Don't Leave It to Chance: The Critical FAT & SAT Checklist for Equipment Procurement

In the high-stakes world of capital equipment procurement, a vague acceptance clause is a direct invitation for cost overruns, project delays, and legal disputes. The Factory Acceptance Test (FAT) and Site Acceptance Test (SAT) are your primary contractual tools to verify performance before final payment. Leaving these standards undefined is a critical sourcing error. Here are the key items your FAT/SAT protocols must explicitly contain.

1. Define Clear, Measurable Performance Criteria. Move beyond subjective terms like "runs properly." Specify exact throughput rates, cycle times, energy consumption, output quality tolerances, and uptime percentages. Reference all applicable American (e.g., ANSI, ASME) or international (ISO) standards. This transforms acceptance from an opinion into a data-driven decision.

2. Detail the Test Environment and Methodology. The FAT must stipulate the exact conditions at the supplier's facility: input material specifications, utility requirements (voltage, air pressure), and ambient conditions. The SAT should account for site-specific variables. Define who provides test materials, the sequence of operations, the duration of the test run, and the roles of both your team and the supplier's personnel.

3. Mandate Documentation and Witnessing. The contract must require comprehensive documentation: calibrated instrument reports, raw test data logs, and signed test result sheets. Crucially, secure the right for your qualified engineers to witness the FAT in person. For the SAT, define responsibilities for installation support, commissioning, and operator training by the supplier.

4. Establish Non-Conformance and Remediation Procedures. What happens if the equipment fails? Your protocol needs a clear process: immediate notification, detailed failure reports, the supplier's proposed corrective action plan with deadlines, and the schedule for re-testing. Define at what point failure constitutes a breach of contract, triggering remedies or termination.

5. Link Tests to Payment and Title Transfer. This is the core commercial safeguard. Structure milestone payments so that a significant portion (often 10-25%) is withheld until successful SAT completion. Explicitly state that title and risk of loss for the equipment do not transfer to you until after SAT sign-off. This aligns the supplier's incentive with delivering a fully functional system.

Procurement best practice is about managing risk. A robust FAT/SAT clause, integrated into your overall supply agreement and logistics plan, is not just technical diligence—it is essential financial and operational protection. Never finalize a contract for industrial equipment without it.
