ASTM C390-02

Standard Practice for Sampling and Acceptance of Thermal Insulation Lots

SCOPE
1.1 This standard provides criteria for establishing the acceptability of lots of shipments of thermal insulation based on sampling and inspection.
1.2 This standard is intended for use in conjunction with appropriate ASTM material specifications that classify and describe the specific physical requirements for the product in terms of qualification requirements and inspection requirements. Determination of nonconformity shall be based on the tolerances for individual sample test values prescribed in the material specification.
1.3 This standard may require inspection substantially different from that performed in the normal course of production. If the purchaser requires sampling and acceptance inspection in accordance with this practice, he shall so specify in the order or contract.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
