    Significance and Use

    4.1 This practice is intended to aid in the selection of test protocols for reinforced pultruded composites.

    4.2 This practice is intended to define the locations from which test specimens shall be taken from the reinforced pultruded composite.

    1. Scope

    1.1 This protocol summarizes the applicable ASTM and other standard test methods commonly used for pultruded composites. The individual performance requirements to these test methods are defined by specific customer specifications.

    1.2 This protocol also defines appropriate specimen locations for sampling from the pultruded composites.

    1.3 This protocol does not discuss all possible standard test methods that may be utilized for pultruded composites.

    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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

    Note 1: There is no known ISO equivalent to this guide.

    1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
