Standard Specification for Dimensional Tolerance of Thermosetting Glass-Reinforced Plastic Pultruded Shapes
|Publication Date:||1 March 2008|
|ICS Code (Laminated sheets):||83.140.20|
1.1 This specification defines tolerances applicable to standard rods, bars, and shapes pultruded from thermosetting glass-reinforced plastics.
1.2 These dimensional tolerances apply to all shapes specified as "standard" by the pultrusion industry.
1.3 Custom shapes and products designed for special applications shall carry specific tolerances that may vary from the standard because a change in type or amount of reinforcement used in a composite directly affects dimensions. The tolerances may be wider or tighter than associated with "standard" shapes.
1.4 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 similar or equivalent ISO standard.
