Robot Joint FAT/SAT and Measurement Acceptance Decision Matrix

Assign each requirement to a declared DUT, method, condition, measurement chain, tolerance, evidence record, verification stage, owner, exception route and authorized sign-off. Silence is not compliance.

Stage boundary

Stage	Primary decision	Required evidence	Not proven
R&D characterization	Behavior across declared conditions	Synchronized data, calculations, state and validity record	Every-unit release
EOL screening	Unit release under the approved sequence	Unit ID, recipe, checks, result, exception and disposition	Full design characterization
FAT	Agreed factory configuration and methods	Samples/utilities, checks, selected runs, deviations, punch list and witness	Buyer-site installation
SAT / commissioning	Delivered system within the agreed site boundary	Installation, utilities/interfaces, agreed runs, training, open items and sign-off	Excluded requirements
Production release	Controlled routine measurement process	Released method, trained roles, reference checks, permissions, backup and escalation	Capability after uncontrolled change

Requirement-to-acceptance record

Requirement ID / revision	Buyer requirement	Supplier response	DUT / method / condition	Measurement / decision rule	Evidence / stage / owner	Status / sign-off
		Compliant / Deviation / Option / Excluded / Clarification required

Exception and retest

Record ID	Observed condition / impact	Containment / owner / due date	Correction or configuration change	Retest link / disposition / approval

Scope limit: No universal Weiheng tolerance, uncertainty ratio, cycle time, delivery, warranty or acceptance value is asserted. Remote commissioning does not automatically replace agreed SAT or buyer sign-off.
