A project-controlled FAT plan for drawings, dimensions, operation, services, defects and shipment release
Quick Answer
An expandable container house factory acceptance test, or FAT, is an agreed inspection and test event before shipment. Buyers should witness the checks that matter to the exact order: unit identity, approved drawings, critical dimensions, expandable operation, openings, finishes, selected electrical and plumbing work, wet-area details, loose items and packing readiness.
A generic checklist is not the acceptance standard. The contract, approved drawing, specification and inspection-and-test plan must define criteria, methods, sample size, witness points, records and authority to release shipment.
What Xutuo House Publishes – and What Still Needs Confirmation
Xutuo’s official service and OEM/ODM pages support requirements confirmation, customization and production discussions, but the reviewed pages do not publish one universal FAT protocol, tolerance set, test pressure, electrical test value or automatic third-party inspection package. These must be agreed for the selected model and destination.
| Evidence boundary: Xutuo facts in this article are attributed to current manufacturer pages. Project dimensions, materials, performance, approvals, packing, commercial terms and site responsibilities must be confirmed in the selected model’s current drawings and order documents. |
1. Issue the FAT Plan Before Production Is Complete
Identify units, order lines, drawing revisions, documents, characteristics, test methods, acceptance criteria, sample size, witness parties and hold points. State whether inspection is by the buyer, Xutuo, an independent party or a combination.
Link the FAT date to readiness evidence. A unit should not be presented while required work remains concealed, drawings are obsolete or measuring and test equipment is unavailable.
- Order and unit identity
- Approved documents
- Inspection and test characteristics
- Witness and hold points
- Release authority
2. Review Documents and Traceability
Start with the purchase order, approved drawings, inclusion schedule, component references, approved deviations and prior inspection records. Confirm labels or serial references that connect the inspected unit and loose parts to those documents.
Mark missing evidence as open rather than assuming compliance. Where destination certificates or reports are required, verify their scope, issuer, model relationship and validity instead of checking only that a file exists.
- Purchase and drawing revision
- Options and deviations
- Component identification
- Required evidence
- Unit and package traceability
3. Inspect Dimensions, Layout and Finish
Measure agreed external and critical internal dimensions, openings, service locations and furniture clearances. Compare the physical layout with the approved plan. Inspect visible finishes, damage, contamination, sharp edges, door and window operation and access to maintainable components.
Use specified tolerances only. If none are approved, record actual measurements and obtain a disposition rather than inventing a pass limit during inspection.
- Critical dimension schedule
- Room and opening positions
- Door and window operation
- Finish and damage review
- Maintenance access
4. Witness the Expandable Function
Use the approved method and safety controls to open or operate the selected unit. Observe alignment, supports, hinges, locks, joints, seals, roof interfaces and any temporary restraints. Record abnormal resistance, interference, noise or damage.
A demonstration time is not a universal installation time. The FAT should distinguish factory operation from site placement, anchoring, weather completion, utility connection and commissioning.
- Approved operating sequence
- Safety exclusion and support
- Alignment and locking
- Joint and seal interfaces
- Post-cycle inspection
5. Test the Ordered Services and Wet Areas
Apply only the tests defined for the order and destination. Electrical checks may cover identified circuits, protective devices, polarity, continuity or function as specified. Plumbing checks may cover routes, joints, fixtures, drainage and leak testing as specified. Wet-area review may include membranes, penetrations and drainage details before concealment.
Record test method, criterion, result, date, unit, instrument and witness. Factory checks do not replace qualified site connection, destination inspection or commissioning after transport and installation.
- Order-specific electrical checks
- Order-specific plumbing checks
- Wet-area hold points
- Traceable test records
- Site retest responsibility
6. Close Defects and Release Packing
List every non-conformance with location, evidence, responsible party and due date. After repair, verify the correction and any affected function. A promise to repair later is not a closed FAT item.
Then reconcile installed and loose items, protection, labels, package marks, final dimensions and gross weights. Shipment release should identify accepted exceptions and the exact documents that support release.
- Punch-list ownership
- Repair and retest
- Accepted deviation authority
- Loose-parts reconciliation
- Packing and shipment release
What to Send Xutuo House for an Order-Specific Reply
A useful inquiry gives the sales and technical teams enough information to answer the real project. Send one numbered request and ask for assumptions, exclusions and pending items to be stated rather than filled silently.
- Purchase order and selected model
- Approved drawings and inclusion schedule
- Inspection-and-test plan
- Destination requirements
- Witness and sampling plan
- Test criteria and instruments
- Defect closure process
- Packing release documents
Recommended Buyer Sequence
- Agree FAT scope before completion.
- Confirm unit identity and controlling documents.
- Inspect dimensions, layout and finish.
- Witness the expandable function safely.
- Complete specified service and wet-area checks.
- Close defects and authorize packing in writing.
Frequently Asked Questions
Is FAT the same as a factory audit?
No. FAT accepts specified units or order characteristics; an audit evaluates broader systems or capability.
Does Xutuo publish one standard FAT?
No universal protocol was identified on the reviewed pages. Agree the order-specific plan.
Can FAT prove local building approval?
No. It provides manufacturing evidence; destination approval also depends on design, site work and authority review.
Must every unit be fully tested?
Sampling or 100-percent checks should be defined by the contract and risk, not assumed.
Can photos replace witnessing?
Photos are useful records but may not prove method, result or unit identity without a controlled plan.
When can shipment be released?
After required checks, defect closure, document review and packing conditions meet the agreed release criteria.
Request a Defined Quotation from Xutuo House
Send the destination, intended use, quantity, selected model or required layout, option list, site constraints and evidence requirements. Ask Xutuo to identify the drawing revision, inclusions, exclusions, package assumptions and buyer responsibilities in its response.
