Meaning
Contractual specification boundaries define the acceptable physical and dimensional limits for supplied resin batches or molded components. Initiating a non-conformance dispute occurs when incoming material tests or part measurements fall outside agreed quality control thresholds. Third-party analytical testing resolves disagreement between resin compounder lot certificates and moulder receiving inspection data.
The process establishes formal procedures for quarantining suspect inventory, assigning financial liability, and determining corrective actions without halting downstream assembly lines.
Commercial Risk
Unresolved material defects lead to unexpected tool wear or structural part failure in service. Holding a non-conformance dispute requires clear segregation of disputed resin lots to prevent cross-contamination with approved inventory. Financial exposure includes raw resin purchase costs, lost machine hours, and labor expenses incurred during non-conforming runs.
Verification Procedure
Standardized test procedures evaluate melt flow rate and tensile yield strength against datasheet thresholds. Retain samples stored at resin delivery serve as the neutral reference material during re-testing. Discrepancies between supplier certificate of analysis records and converter laboratory findings highlight testing protocol offsets or sample degradation during transport.
Contract Settlement
Formal resolution remedies include full lot credit, replacement resin shipments, or negotiated price downgrades for less demanding applications. Technical concessions allow minor out-of-spec lots to run under modified processing parameters when structural integrity remains uncompromised. Written settlement documentation updates acceptable quality limit parameters for future supply contracts.
