1. Scope

1.1 This guide covers the testing of molded automotive/industrial composite materials. It is intended to increase the users awareness of the special considerations necessary for the testing of these materials. In addition, the user is provided with a comparison of some of the more commonly used ASTM International standard test methods that are applicable for evaluating automotive/industrial composites.

1.2 Areas in which current ASTM International standard test methods do not meet the needs for testing of automotive/industrial composites are indicated. This provides direction for future standardization work.

1.3 It is not the intent of this guide to cover all test methods which could possibly be used for automotive/industrial composites. Only the most commonly used and most applicable standards are included.

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.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
