Formerly under the jurisdiction of Committee D20 on Plastics, this practice was withdrawn in July 2022. This standard is being withdrawn without replacement because this standard is obsolete and not specified in any known specifications or standards other than D7745.

This practice outlines a method for classifying reinforced plastic pultruded shapes according to their composition. In classifying the reinforced plastic pultruded shape according to composition, four separate aspects of the composition shall be considered: reinforced material; reinforcement type; resin type; and filler amount. The composition shall be identified by the use of four capital letters. The sequential position of each letter shall have particular significance in describing the composition.

1.1 This practice outlines a method for classifying reinforced plastic pultruded shapes according to their composition.

1.2 One objective of this practice is to provide a codification means and descriptive limits for classification.

1.3 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.

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