ISO 22095 Mass Balance Chain of Custody Audit Requirements
ISO 22095 mass balance audits demand strict site boundaries, verified baseline yield conversions, and zero negative credit balances across accounting periods.
Product Claim Validation
Meaning
Conformity assessment procedures verify that a manufactured plastic resin or moulded component satisfies specified mechanical or thermal performance attributes. Conducting product claim validation involves rigorous laboratory testing and statistical process control reviews. The procedure governs marketing claims and technical datasheet metrics for plastic products.
It stops at documented performance boundaries and does not cover unstated operating conditions or unverified field applications.
Datasheet Verification
Laboratory testing protocols measure tensile modulus and heat deflection temperature against standardized test methods. Technical teams performing product claim validation test multiple resin lots under controlled ambient conditions to establish true baseline values. Relying on single sample datasheets leads to non-compliance during customer incoming quality audits.
Regulatory Audit
Compliance audits check toxicological disclosures and food contact migration limits against regional chemical registries. Executing product claim validation protects resin suppliers from legal penalties associated with misleading environmental declarations. Audit failure requires immediate product recall and expensive re-testing of distributed production lots.
Processing Assurance
Moulding trials verify that resin batches meet target processing behavior during high volume manufacturing runs. Technical specialists apply product claim validation methods to confirm melt flow rate consistency and minimal batch to batch shrinkage variation. Inconsistent resin flow causes dimensional defects and unacceptable scrap rates in automated injection lines.
