This practice covers acceptance criteria for visual inspection of parts made from glass-reinforced plastic laminates. It presents word descriptions of possible defects to serve as a guide for contracts, drawings, product specifications, and final inspection. This practice also categorizes different inspection requirements for levels of product quality. The acceptance criteria shall be applied to the following: dimensions and tolerances, inserts, molded-in threads or cored holes, workmanship, critical area, allowable visual defects, repairable defects, surface finish, and surface appearance. Four acceptance levels for visual inspection are described: Acceptance Level I, Acceptance Level II, Acceptance Level III, and Acceptance Level IV.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

1.1 This practice covers acceptance criteria for visual inspection of parts made from molded glass-reinforced plastic laminates.
1.2 This practice presents word descriptions of possible defects to serve as a guide for contracts, drawings, product specifications, and final inspection.
1.3 This practice also categorizes different inspection requirements for levels of product quality.
1.4 The allowable size and frequency of permitted defects within the acceptance level categories of this specification are general and not related to specific service requirements. A Level IV of allowable defects which defines allowable size, frequency, and permitted repair procedures should be established for specific service requirements as agreed upon between the purchaser and the supplier.
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.6 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.
