ASTM D4851-97(2003) - 10.1.1997
 
1. Scope

1.1 These test methods cover the testing of coated and laminated fabrics made primarily for use in fabric roof systems. These coated and laminated fabrics are generally in either an air supported or tension supported construction of fabric roof systems.

1.2 These test methods provide procedures to test coated and laminated fabrics used in fabric roof systems. These methods can be used for most fiber-based, coated and laminated architectural fabrics.

1.3 This standard includes the following sections that provide test procedures for coated and laminated architectural fabrics:

Section Fabric Count 8 Mass per Unit Area 9 Fabric Thickness 10 Fabric Width 11 Fabric Length 12 Fabric Bow 13 Adhesion of Coating to Fabric 14 Uniaxial Elongation Under Static Load 15 Fabric Breaking Strength 16 Breaking Strength After Crease Fold 17 Elongation at Break 18 Fabric Trapezoid Tear Strength 19 Resistance to Accelerated Weathering 20 Solar Optical Properties 21 Fabric Flame Resistance 22 Noise Reduction Coefficient 23

1.4 These test methods include only testing procedures and do not include specifications or tolerances. They are intended as a guide for specifications. Any of these methods may be used in material specifications to evaluate requirements for a specific end use as related to a particular job.

1.5 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of 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. See Note 6, Note A1.1, Note A2.1, and Note A3.1.
