(Test Method)Standard Test Method for Windload Resistance of Rigid Poly(Vinyl Chloride) (PVC) Siding
Standard Test Method for Windload Resistance of Rigid Poly(Vinyl Chloride) (PVC) Siding
SCOPE
1.1 This test method describes methods for testing and evaluating windload resistance of rigid poly(vinyl chloride) (PVC) siding when fastened in accordance with Practice D4756.
1.2 The proper use of this test method requires a knowledge of the principles of pressure measurement.
1.3 This test method describes the apparatus and the procedures to be used for either a specific static test pressure (Procedure A) or ultimate test pressure values (Procedure B) applied uniformly to a specimen. Note 1-There are no ISO standards covering the subject matter of this test method.
1.4 The values expressed in inch-pound units are to be regarded as the standard. The SI equivalents in parentheses may be approximate.
1.5 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. For specific precautionary statements, see Section 7.
