Don't Get Burned by Vague Contracts: The FAT/SAT Checklist Every Buyer Needs

In global B2B procurement, especially for high-value industrial machinery, the contract is your first line of defense. Yet, a surprisingly common and costly pitfall is an ambiguous equipment acceptance clause. Vague terms like "machine shall perform satisfactorily" are an open invitation for disputes, delays, and budget overruns. The structured Factory Acceptance Test (FAT) and Site Acceptance Test (SAT) are your contractual tools to prevent this. Here are the critical items these protocols must explicitly define.

1. Performance Specifications & Tolerances: The protocol must list every key performance metric (e.g., throughput rate, accuracy, energy consumption, output quality) with clear, measurable pass/fail criteria and acceptable tolerances. Avoid subjective language. Specify the exact test conditions (input materials, ambient temperature, run duration) to replicate real-world operation.

2. Documentation & Compliance Verification: The FAT is your chance to verify compliance before shipment. The checklist must include reviewing all manuals, technical data sheets, CE/UL certifications, and material test reports. Confirm that nameplate data matches the order and that all required safety devices are installed and functional.

3. Pre-Shipment Inspection (FAT Focus): Beyond performance, the FAT should cover visual inspection for workmanship, verification of components against the bill of materials, and complete functional testing of all subsystems. Document any non-conformities with a clear remediation plan and re-test requirement before authorizing shipment.

4. Site-Specific Conditions & Reassembly (SAT Focus): The SAT clause must account for site variables. It should state who provides utilities (power, air, water), foundation requirements, and environmental conditions. Crucially, it must define that successful FAT does not waive the right to SAT, and specify the process for testing after reassembly and integration at your facility to ensure no damage occurred during logistics.

5. Roles, Responsibilities, and Timeline: Clearly define who attends (supplier engineers, your team, third-party inspectors), who provides test materials, and who operates the equipment. Set a fixed window for SAT after delivery. Specify the consequences of a failed test—typically, the supplier bears the cost of rework, re-testing, and any resulting project delays.

6. The Punch List & Final Acceptance: The protocol must outline the process for creating a punch list of minor deficiencies (e.g., software bugs, small spare parts). Define a timeframe for rectification and link the release of the final payment milestone to the formal signing of the SAT certificate, not just delivery.

Integrating this detailed FAT/SAT framework into your procurement contract transforms it from a simple purchase agreement into a powerful project management and risk mitigation tool. It aligns supplier incentives with your success, ensures compliance, and provides a clear roadmap for successful equipment commissioning. Before signing, ask not just if the machine works, but exactly how and when you will prove it.
