Standard Specification for Dimensional Tolerance of Thermosetting Glass-Reinforced Plastic Pultruded Shapes

2015

5

ASTM Vol.08.02 (2022)

This specification defines production tolerances applicable to standard rods, bars, shapes, and flat sheet pultruded from thermosetting glass-reinforced plastics. These dimensional tolerances apply to all shapes specified as “standard” by the pultrusion industry. Custom shapes and products designed for special applications may carry specific tolerances that vary from the standard. The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. The following safety hazards caveat pertains only to the test methods portion, Section 4, of this specification: 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.
