ASTM-D4225 › Standard Specification for Styrene-Butadiene Sheeting (Withdrawn 2009)
The following bibliographic material is provided to assist you with your purchasing decision:
This specification covers styrene-butadiene sheeting in thicknesses of 0.25 mm [0.01 in.] and greater. Sheeting conforming to this specification is intended for use in instrument housings and applications requiring resistance to impact. Methods of fabrication may require that the sheet be drawn or bent. The styrene-butadiene sheeting is classified by type as follows: type I - low shrinkage, type II - intermediate shrinkage, and type III - high shrinkage. The styrene-butadiene sheeting is further divided into classes and sizes as follows: class 1 - natural, class 2 - as specified by user, size A - 0.5 by 1 m, and size B - as specified by user. The impact strength, Vicat softening temperature, flow rate, and tensile stress at yield of the material shall be tested to meet the requirements specified. The orientation, and warpage or twist shall be tested to meet the requirements prescribed.
Scope
1.1 This specification covers styrene-butadiene sheeting in thicknesses of 0.25 mm (0.01 in.) and greater. Sheeting conforming to this specification is intended for use in instrument housings and applications requiring resistance to impact. Methods of fabrication may require that the sheet be drawn or bent.
1.2 This specification covers natural and colored sheeting.
1.3 This specification covers quality requirements that include degree of orientation, amount of warpage or twist, dimensions, tolerances, and workmanship.
1.4 The values stated in SI units are to be regarded as the standard. The SI units given in parentheses are for information only.
1.5 The following precautionary statement pertains to the test method portion only, Section 12, of this specification: This standard does not purport to address the safety problems 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.
