ASTM D2586-68(1990)e1

Standard Test Method for Hydrostatic Compressive Strength of Glass-Reinforced Plastic Cylinders (Withdrawn 1996)

SCOPE
1.1 This test method covers the determination of the compressive strength properties of filament-wound glass reinforced plastic cylinders of standard size in hydrostatic compression. This test method is generally applicable to hollow cylinders made of glass reinforced plastics, and particularly those formed by filament winding. This test method may be applied to both unidirectional and orthotropic laminates, but is limited to constructions containing greater than 50% by weight of glass reinforcement.  
1.2 The values stated in inch-pound units are to be regarded as the standard. The values in parentheses are for information only.  
1.3 This standard does not purport to address all of the safety problems, 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. >
