Its purpose is to confirm that specified equipment, control functions, electrical systems, sensors, motors and selected mechanical operations are assembled and functioning as agreed before shipment.<\/p>\n<p>For buyers, the most important point is understanding what FAT can prove and what it cannot. Factory testing can confirm a large part of the control and equipment package, but it cannot fully reproduce the final foundations, field wiring, site utilities, real aggregate flow, installed silos, truck circulation or local environmental conditions.<\/p>\n<p>Our <a href=\"https:\/\/mixingplantpro.com\/id\/customization\/\">customized batching plant services<\/a> include project-specific equipment configuration, plant layout and automation integration. This guide explains how batching plant factory acceptance testing should be planned, documented and separated from site acceptance and commissioning.<\/p>\n<h2>What Is Batching Plant Factory Acceptance Testing?<\/h2>\n<figure class=\"wp-block-image aligncenter size-full\" style=\"text-align:center;margin:28px auto;\"><img fetchpriority=\"high\" decoding=\"async\" src=\"https:\/\/mixingplantpro.com\/wp-content\/uploads\/2026\/08\/Precast-Concrete-Batching-Plant03.jpg\" alt=\"Peralatan pencampuran beton pracetak dan sistem pengumpanan material\" width=\"800\" height=\"600\" style=\"display:block;margin-left:auto;margin-right:auto;max-width:100%;height:auto;\" \/><\/figure>\n<p>Batching plant factory acceptance testing is a pre-shipment verification carried out at the manufacturer&#8217;s facility.<\/p>\n<p>The FAT normally checks whether the supplied equipment and automation system conform to the approved technical specification.<\/p>\n<p>Depending on project scope, this can include:<\/p>\n<ul>\n<li>equipment identification;<\/li>\n<li>control cabinet inspection;<\/li>\n<li>PLC and HMI functions;<\/li>\n<li>motor rotation and interlocks;<\/li>\n<li>sensor signals;<\/li>\n<li>weighing-system simulation;<\/li>\n<li>alarm functions;<\/li>\n<li>recipe and batch-record logic;<\/li>\n<li>selected no-load mechanical tests;<\/li>\n<li>documentation review.<\/li>\n<\/ul>\n<p>IEC 62381:2024 provides a formal framework for Factory Acceptance Test, Site Acceptance Test and Site Integration Test of automation systems, emphasizing that test scope and responsibilities should be agreed in advance.<\/p>\n<h2>FAT Should Be Based on the Approved Technical Specification<\/h2>\n<p>A useful FAT is not an informal demonstration.<\/p>\n<p>Batching plant factory acceptance testing should compare the equipment against approved project documents such as:<\/p>\n<ul>\n<li>equipment list;<\/li>\n<li>general arrangement drawings;<\/li>\n<li>control philosophy;<\/li>\n<li>I\/O list;<\/li>\n<li>motor list;<\/li>\n<li>electrical drawings;<\/li>\n<li>recipe requirements;<\/li>\n<li>interface requirements;<\/li>\n<li>scope-of-supply matrix.<\/li>\n<\/ul>\n<p>If the project specification is unclear, the FAT cannot resolve the ambiguity by itself.<\/p>\n<p>Our <a href=\"https:\/\/mixingplantpro.com\/id\/lingkup-pasokan-batching-plant\/\">batching plant scope of supply guide<\/a> explains why equipment and responsibility boundaries should be finalized before testing begins.<\/p>\n<h2>Agree on the FAT Test Plan Before the Test Date<\/h2>\n<p>Batching plant factory acceptance testing works best when both buyer and supplier agree on the procedure before the equipment is ready.<\/p>\n<table>\n<thead>\n<tr>\n<th>FAT planning item<\/th>\n<th>What should be defined<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Test scope<\/td>\n<td>Which equipment and functions will be tested<\/td>\n<\/tr>\n<tr>\n<td>Test method<\/td>\n<td>How each item will be verified<\/td>\n<\/tr>\n<tr>\n<td>Acceptance criteria<\/td>\n<td>What result is considered

forms<\/td>\n<\/tr>\n<tr>\n<td>Punch list<\/td>\n<td>How open items will be closed<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>A pre-agreed test plan prevents the FAT from becoming a simple equipment walkaround.<\/p>\n<h2>Verify Equipment Identification First<\/h2>\n<p>Before functional testing, confirm that the equipment being inspected is the equipment ordered.<\/p>\n<p>For batching plant factory acceptance testing, verify:<\/p>\n<ul>\n<li>mixer model;<\/li>\n<li>peringkat motor;<\/li>\n<li>gearbox information;<\/li>\n<li>load-cell model;<\/li>\n<li>PLC and HMI hardware;<\/li>\n<li>variable-frequency drives;<\/li>\n<li>sensors;<\/li>\n<li>pneumatic components;<\/li>\n<li>major purchased components.<\/li>\n<\/ul>\n<p>Record nameplates and component labels where useful.<\/p>\n<h2>Inspect Fabrication and Assembly Condition<\/h2>\n<p>FAT can include visual inspection of fabricated structures and assembled equipment.<\/p>\n<p>Periksa:<\/p>\n<ul>\n<li>weld condition;<\/li>\n<li>surface coating;<\/li>\n<li>bolt installation;<\/li>\n<li>guards;<\/li>\n<li>platforms;<\/li>\n<li>access doors;<\/li>\n<li>equipment labels;<\/li>\n<li>cable routing;<\/li>\n<li>pneumatic tubing.<\/li>\n<\/ul>\n<p>Batching plant factory acceptance testing should identify obvious fabrication defects before shipment makes them harder to correct.<\/p>\n<h2>Control Cabinet Inspection Is a Major FAT Activity<\/h2>\n<p>The electrical control cabinet is one of the easiest systems to test thoroughly at the factory.<\/p>\n<p>Ulasan:<\/p>\n<ul>\n<li>component arrangement;<\/li>\n<li>terminal identification;<\/li>\n<li>wire numbering;<\/li>\n<li>PLC modules;<\/li>\n<li>power supplies;<\/li>\n<li>motor protection;<\/li>\n<li>VFDs;<\/li>\n<li>cabinet ventilation;<\/li>\n<li>spare terminals where specified.<\/li>\n<\/ul>\n<p>Batching plant factory acceptance testing can confirm that the cabinet matches the approved electrical drawings before site installation.<\/p>\n<h2>PLC I\/O Testing Should Be Systematic<\/h2>\n<p>Each input and output should be checked against the I\/O list.<\/p>\n<p>Misalnya:<\/p>\n<ul>\n<li>limit switch input;<\/li>\n<li>load-cell signal;<\/li>\n<li>level switch;<\/li>\n<li>motor start output;<\/li>\n<li>solenoid valve output;<\/li>\n<li>alarm signal.<\/li>\n<\/ul>\n<p>The test should confirm that the physical or simulated field signal reaches the correct PLC address and that the intended output is commanded.<\/p>\n<p>Batching plant factory acceptance testing should record any I\/O mismatch as a punch-list item.<\/p>\n<h2>Test HMI Screens and Operator Commands<\/h2>\n<p>The HMI should be checked for both display accuracy and command logic.<\/p>\n<p>Verify:<\/p>\n<ul>\n<li>equipment status;<\/li>\n<li>manual controls;<\/li>\n<li>automatic mode;<\/li>\n<li>recipe selection;<\/li>\n<li>setpoint entry;<\/li>\n<li>alarm pages;<\/li>\n<li>trend pages where included;<\/li>\n<li>izin pengguna;<\/li>\n<li>language settings.<\/li>\n<\/ul>\n<p>Do not limit the test to whether the screen turns on.<\/p>\n<h2>Recipe Management Can Be Verified at FAT<\/h2>\n<p>Recipe logic is well suited to factory testing.<\/p>\n<p>Batching plant factory acceptance testing can verify:<\/p>\n<ul>\n<li>recipe creation;<\/li>\n<li>recipe editing;<\/li>\n<li>ingredient assignment;<\/li>\n<li>target quantities;<\/li>\n<li>recipe selection;<\/li>\n<li>revision control where included;<\/li>\n<li>operator permissions.<\/li>\n<\/ul>\n<p>Use representative project recipes rather than generic demo values where possible.<\/p>\n<h2>Automatic Sequence Logic Can Be Tested Without Real Concrete<\/h2>\n<p>The PLC can run through a simulated batching sequence using test signals.<\/p>\n<p>This can confirm:<\/p>\n<ul>\n<li>aggregate weighing sequence;<\/li>\n<li>powder weighing sequence;<\/li>\n<li>water and admixture sequence;<\/li>\n<li>pengisian mixer;<\/li>\n<li>mixing timer logic;<\/li>\n<li>discharge command;<\/li>\n<li>next-batch preparation.<\/li>\n<\/ul>\n<p>Batching plant factory acceptance testing can therefore prove control sequencing even when the full plant is not processing real aggregate.<\/p>\n<h2>Interlocks Are One of the Most Important FAT Checks<\/h2>\n<p>Interlocks prevent the control system from issuing unsafe or logically incorrect commands.<\/p>\n<p>Examples include:<\/p>\n<ul>\n<li>do not discharge a weigh hopper unless the receiving path is ready;<\/li>\n<li>do not start a screw conveyor if the downstream valve is closed where the logic requires it;<\/li>\n<li>do not open mixer discharge when the receiver is not confirmed;<\/li>\n<li>do not start automatic batching when a critical fault is active.<\/li>\n<\/ul>\n<p>Batching plant factory acceptance testing should deliberately create abnormal conditions to confirm that interlocks respond correctly.<\/p>\n<h2>Alarm Testing Should Include Failure Scenarios<\/h2>\n<figure class=\"wp-block-image aligncenter size-full\" style=\"text-align:center;margin:28px auto;\"><img decoding=\"async\" src=\"https:\/\/mixingplantpro.com\/wp-content\/uploads\/2026\/08\/Side-mounted-belt-concrete-mixing-plant02.jpg\" alt=\"Tata letak pabrik pencampuran beton sabuk yang dipasang di samping dengan silo bubuk\" width=\"800\" height=\"600\" style=\"display:block;margin-left:auto;margin-right:auto;max-width:100%;height:auto;\" \/><\/figure>\n<p>An alarm system should not be tested only by viewing the alarm page.<\/p>\n<p>Trigger representative faults such as:<\/p>\n<ul>\n<li>motor overload;<\/li>\n<li>sensor failure;<\/li>\n<li>weighing timeout;<\/li>\n<li>high or low level;<\/li>\n<li>communication loss;<\/li>\n<li>emergency-stop activation.<\/li>\n<\/ul>\n<p>Verify:<\/p>\n<ul>\n<li>alarm text;<\/li>\n<li>alarm priority;<\/li>\n<li>equipment response;<\/li>\n<li>reset logic;<\/li>\n<li>alarm history.<\/li>\n<\/ul>\n<h2>Motor Rotation Can Often Be Verified Before Shipment<\/h2>\n<p>Where the equipment is assembled and safe to operate, FAT can verify motor direction for:<\/p>\n<ul>\n<li>mixer drives;<\/li>\n<li>konveyor;<\/li>\n<li>konveyor sekrup;<\/li>\n<li>pumps;<\/li>\n<li>fans.<\/li>\n<\/ul>\n<p>Batching plant factory acceptance testing should record the result before components are disconnected for shipping.<\/p>\n<p>However, final rotation should still be checked again after site wiring because phase sequence can change.<\/p>\n<h2>No-Load Mechanical Operation Can Be Verified<\/h2>\n<p>Some equipment can be operated without production material.<\/p>\n<p>Possible checks include:<\/p>\n<ul>\n<li>mixer rotation;<\/li>\n<li>belt conveyor travel;<\/li>\n<li>screw conveyor rotation;<\/li>\n<li>gate opening and closing;<\/li>\n<li>pneumatic cylinder motion;<\/li>\n<li>lubrication-system operation.<\/li>\n<\/ul>\n<p>These checks confirm basic mechanical function but do not prove production performance under load.<\/p>\n<h2>Gate and Valve Feedback Should Match Actual Position<\/h2>\n<p>A control system may command a valve open while the position feedback remains incorrect.<\/p>\n<p>Batching plant factory acceptance testing should confirm both command and feedback for critical devices.<\/p>\n<p>Periksa:<\/p>\n<ul>\n<li>aggregate gates;<\/li>\n<li>powder valves;<\/li>\n<li>water valves;<\/li>\n<li>admixture valves;<\/li>\n<li>mixer discharge gates.<\/li>\n<\/ul>\n<p>This is especially important where automatic sequence logic depends on confirmed position.<\/p>\n<h2>Weighing Signals Can Be Tested at FAT<\/h2>\n<p>Load cells and indicators can be checked for signal stability and basic operation at the factory.<\/p>\n<p>Depending on assembly condition, batching plant factory acceptance testing can verify:<\/p>\n<ul>\n<li>zero signal;<\/li>\n<li>load-cell wiring;<\/li>\n<li>indicator response;<\/li>\n<li>scale assignment;<\/li>\n<li>software display;<\/li>\n<li>high\/low limits.<\/li>\n<\/ul>\n<p>Reference weights may also be used if the weigh hopper is fully assembled and accessible.<\/p>\n<h2>FAT Does Not Replace Final Scale Verification<\/h2>\n<p>NRMCA requires scale accuracy verification through the actual range of use and documentation of test loads, indicated values and errors. It also notes that scale accuracy should be reverified when portable plants are moved or when maintenance affects weighing systems.<\/p>\n<p>This is why batching plant factory acceptance testing does not eliminate the need for final site scale verification.<\/p>\n<p>Shipping, reassembly, foundation condition and field connections can all affect weighing systems.<\/p>\n<h2>Water Meter and Admixture Signals Can Be Simulated<\/h2>\n<p>FAT can verify:<\/p>\n<ul>\n<li>meter pulse input;<\/li>\n<li>totalizer logic;<\/li>\n<li>target calculation;<\/li>\n<li>valve command;<\/li>\n<li>alarm logic.<\/li>\n<\/ul>\n<p>However, final accuracy should be checked with the actual installed water and admixture system.<\/p>\n<p>NRMCA requires periodic verification of water meters, admixture dispensers and moisture probes as part of plant certification.<\/p>\n<h2>Moisture Correction Logic Can Be Tested by Simulation<\/h2>\n<p>The actual moisture sensor may not be installed in final aggregate conditions during FAT.<\/p>\n<p>But the control logic can still be tested.<\/p>\n<p>For batching plant factory acceptance testing, enter or simulate different moisture values and confirm that the system adjusts:<\/p>\n<ul>\n<li>wet aggregate target;<\/li>\n<li>added water target;<\/li>\n<li>batch record.<\/li>\n<\/ul>\n<p>Our <a href=\"https:\/\/mixingplantpro.com\/id\/aggregate-moisture-correction-concrete-batching-guide\/\">panduan koreksi kelembaban agregat<\/a> explains the underlying material-balance logic.<\/p>\n<h2>Batch Records and Reports Should Be Reviewed at FAT<\/h2>\n<p>NRMCA&#8217;s plant inspection program evaluates the recording capabilities for batched materials at concrete plants.<\/p>\n<p>Batching plant factory acceptance testing is a good time to verify:<\/p>\n<ul>\n<li>target quantities;<\/li>\n<li>actual quantities;<\/li>\n<li>batch ID;<\/li>\n<li>recipe name;<\/li>\n<li>date and time;<\/li>\n<li>operator;<\/li>\n<li>alarm or override information;<\/li>\n<li>report export.<\/li>\n<\/ul>\n<p>Use sample batches to confirm the report contains the fields required by the project.<\/p>\n<h2>Data Backup and Restore Should Be Tested<\/h2>\n<p>Automation systems should have a clear recovery method.<\/p>\n<p>FAT can verify:<\/p>\n<ul>\n<li>PLC program backup;<\/li>\n<li>HMI project backup;<\/li>\n<li>recipe database backup;<\/li>\n<li>report database backup;<\/li>\n<li>restore procedure.<\/li>\n<\/ul>\n<p>Batching plant factory acceptance testing should record the software version delivered with the equipment.<\/p>\n<h2>Remote Access Should Be Tested If It Is in Scope<\/h2>\n<p>If remote diagnostics or remote support are part of the agreed system, verify them before shipment.<\/p>\n<p>Periksa:<\/p>\n<ul>\n<li>connection method;<\/li>\n<li>izin pengguna;<\/li>\n<li>security controls;<\/li>\n<li>logging;<\/li>\n<li>customer IT requirements.<\/li>\n<\/ul>\n<p>Do not assume remote access will function at site if network requirements were never defined.<\/p>\n<h2>Third-Party Interfaces Need Simulation<\/h2>\n<figure class=\"wp-block-image aligncenter size-full\" style=\"text-align:center;margin:28px auto;\"><img decoding=\"async\" src=\"https:\/\/mixingplantpro.com\/wp-content\/uploads\/2026\/08\/Precast-Concrete-Batching-Plant04.jpg\" alt=\"Silo bubuk dan konveyor sekrup di dalam pabrik beton pracetak\" width=\"800\" height=\"600\" style=\"display:block;margin-left:auto;margin-right:auto;max-width:100%;height:auto;\" \/><\/figure>\n<p>A concrete batching plant may exchange data with:<\/p>\n<ul>\n<li>ERP;<\/li>\n<li>truck dispatch;<\/li>\n<li>precast production software;<\/li>\n<li>external weighing systems;<\/li>\n<li>laboratory systems.<\/li>\n<\/ul>\n<p>Where possible, batching plant factory acceptance testing should simulate the interface.<\/p>\n<p>IEC 62381:2024 also distinguishes factory integration testing and site integration testing, which is useful when several systems need to communicate.<\/p>\n<h2>Emergency Stops and Safety Circuits Should Be Tested<\/h2>\n<p>Where the safety circuit is complete at the factory, verify:<\/p>\n<ul>\n<li>emergency-stop devices;<\/li>\n<li>safety relays;<\/li>\n<li>guard switches where included;<\/li>\n<li>motor shutdown response;<\/li>\n<li>reset logic.<\/li>\n<\/ul>\n<p>Batching plant factory acceptance testing should not bypass safety circuits simply to make the demonstration easier.<\/p>\n<h2>FAT Can Check Documentation Completeness<\/h2>\n<p>Before shipment, confirm that the document package includes the agreed items.<\/p>\n<p>Possible documents include:<\/p>\n<ul>\n<li>general arrangement drawing;<\/li>\n<li>equipment list;<\/li>\n<li>foundation-load data;<\/li>\n<li>electrical drawings;<\/li>\n<li>I\/O list;<\/li>\n<li>motor list;<\/li>\n<li>operation manual;<\/li>\n<li>maintenance manual;<\/li>\n<li>spare-parts list;<\/li>\n<li>lubrication information.<\/li>\n<\/ul>\n<p>Missing documentation is easier to correct before the project reaches installation.<\/p>\n<h2>FAT Can Confirm Spare Parts and Loose Items<\/h2>\n<p>Spare parts, sensors, tools and accessories that will ship separately should be checked against the packing list.<\/p>\n<p>Batching plant factory acceptance testing can verify:<\/p>\n<ul>\n<li>commissioning spares;<\/li>\n<li>wear parts;<\/li>\n<li>special tools;<\/li>\n<li>loose sensors;<\/li>\n<li>cables;<\/li>\n<li>manuals.<\/li>\n<\/ul>\n<p>Photographic records can help during site receipt inspection.<\/p>\n<h2>What FAT Cannot Fully Verify<\/h2>\n<p>Some important plant functions depend on final site conditions.<\/p>\n<p>Batching plant factory acceptance testing generally cannot fully prove:<\/p>\n<ul>\n<li>foundation performance;<\/li>\n<li>final plant alignment;<\/li>\n<li>site utility quality;<\/li>\n<li>actual aggregate flow;<\/li>\n<li>real cement flow from installed silos;<\/li>\n<li>actual water pressure;<\/li>\n<li>sirkulasi truk;<\/li>\n<li>site dust-control performance;<\/li>\n<li>final production capacity;<\/li>\n<li>concrete quality under real materials.<\/li>\n<\/ul>\n<p>These items belong to installation checks, SAT or commissioning.<\/p>\n<h2>FAT Does Not Prove Rated Production Capacity<\/h2>\n<p>Running motors and simulated batching does not demonstrate sustained concrete output.<\/p>\n<p>Actual capacity depends on:<\/p>\n<ul>\n<li>real aggregate;<\/li>\n<li>powder flow;<\/li>\n<li>air dan dosis campuran;<\/li>\n<li>waktu pencampuran;<\/li>\n<li>waktu pelepasan;<\/li>\n<li>truck or bucket availability;<\/li>\n<li>site logistics.<\/li>\n<\/ul>\n<p>Our <a href=\"https:\/\/mixingplantpro.com\/id\/concrete-batching-plant-capacity-rated-vs-actual\/\">concrete batching plant capacity guide<\/a> explains why rated output should be separated from practical production.<\/p>\n<h2>FAT Does Not Replace Site Acceptance Testing<\/h2>\n<p>Site Acceptance Testing confirms the equipment after shipment, erection and final connection.<\/p>\n<p>IEC 62381:2024 treats SAT as a separate stage from FAT because site installation can introduce new variables.<\/p>\n<p>SAT can verify:<\/p>\n<ul>\n<li>field wiring;<\/li>\n<li>final motor rotation;<\/li>\n<li>instrument installation;<\/li>\n<li>utility connections;<\/li>\n<li>site communication interfaces;<\/li>\n<li>safety circuits after reassembly.<\/li>\n<\/ul>\n<h2>Commissioning Goes Beyond SAT<\/h2>\n<p>Commissioning uses actual materials and production conditions.<\/p>\n<p>It may include:<\/p>\n<ul>\n<li>verifikasi skala;<\/li>\n<li>water-meter verification;<\/li>\n<li>moisture-sensor checks;<\/li>\n<li>aggregate feeding;<\/li>\n<li>cement feeding;<\/li>\n<li>real batching;<\/li>\n<li>mixer trials;<\/li>\n<li>production records;<\/li>\n<li>concrete quality tests.<\/li>\n<\/ul>\n<p>NRMCA&#8217;s plant inspection process emphasizes that batching systems should accurately batch concrete without interference and that measuring devices should be verified.<\/p>\n<h2>Use a FAT Punch List<\/h2>\n<p>Not every issue discovered during batching plant factory acceptance testing needs to stop shipment.<\/p>\n<p>Classify punch-list items by severity.<\/p>\n<table>\n<thead>\n<tr>\n<th>Category<\/th>\n<th>Example<\/th>\n<th>Action<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Critical<\/td>\n<td>Control logic or major equipment does not meet specification<\/td>\n<td>Correct before shipment<\/td>\n<\/tr>\n<tr>\n<td>Major<\/td>\n<td>Function works but required feature is incomplete<\/td>\n<td>Agree closure before shipment or site<\/td>\n<\/tr>\n<tr>\n<td>Minor<\/td>\n<td>Label, documentation or cosmetic issue<\/td>\n<td>Record and close by agreed date<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>The buyer and supplier should agree who verifies closure.<\/p>\n<h2>Photographs and Screenshots Improve FAT Records<\/h2>\n<p>A signed checklist is important, but visual evidence can be valuable later.<\/p>\n<p>Rekam:<\/p>\n<ul>\n<li>equipment nameplates;<\/li>\n<li>control cabinet;<\/li>\n<li>HMI screens;<\/li>\n<li>alarm tests;<\/li>\n<li>major mechanical assemblies;<\/li>\n<li>packing condition.<\/li>\n<\/ul>\n<p>These records help compare factory condition with site-received equipment.<\/p>\n<h2>Remote FAT Can Work for Some Projects<\/h2>\n<p>When travel is difficult, part of batching plant factory acceptance testing can be witnessed by live video and shared control-system screens.<\/p>\n<p>Remote FAT can be effective for:<\/p>\n<ul>\n<li>HMI review;<\/li>\n<li>recipe logic;<\/li>\n<li>alarm tests;<\/li>\n<li>I\/O simulation;<\/li>\n<li>documentation review.<\/li>\n<\/ul>\n<p>However, the buyer should decide whether physical inspection of fabrication and equipment is still required.<\/p>\n<h2>What Should Buyers Send Before FAT?<\/h2>\n<figure class=\"wp-block-image aligncenter size-full\" style=\"text-align:center;margin:28px auto;\"><img loading=\"lazy\"

mechanical operation, documentation and pre-shipment completeness against an agreed test plan.<\/p>\n<p>FAT should not be treated as proof of final site performance. Scale accuracy after erection, real material flow, site utilities, production capacity and concrete quality still need SAT and commissioning.<\/p>\n<p>The strongest acceptance process uses FAT, SAT and commissioning as separate but connected stages. That approach catches control and fabrication issues early while still verifying the complete plant under real operating conditions after installation.<\/p>\n<h2>FAQ<\/h2>\n<h3>What is batching plant factory acceptance testing?<\/h3>\n<p>It is a structured pre-shipment test at the supplier&#8217;s factory to verify specified equipment, control logic, electrical systems, alarms, interlocks, selected mechanical functions and documentation.<\/p>\n<h3>Can FAT verify batching plant production capacity?<\/h3>\n<p>Not fully. FAT can test control cycles and no-load equipment, but practical capacity depends on real materials, site utilities, transport and operating conditions that must be verified later.<\/p>\n<h3>Should weighing scales be tested during FAT?<\/h3>\n<p>Basic load-cell response and, where practical, reference-load checks can be performed. Final scale accuracy should still be verified after installation because shipping and reassembly can affect the system.<\/p>\n<h3>What is the difference between FAT and SAT?<\/h3>\n<p>FAT is performed before shipment at the factory. SAT is performed after installation at the project site to verify final wiring, utilities, interfaces and installed equipment functions.<\/p>\n<h3>What documents should be ready before FAT?<\/h3>\n<p>Prepare the approved equipment list, drawings, I\/O list, control philosophy, recipe requirements, interface requirements, test procedure and acceptance criteria.<\/p>","protected":false},"excerpt":{"rendered":"<p>Batching plant factory acceptance testing is the structured verification performed before equipment leaves the supplier&#8217;s factory.
