ASTM D4851 : 97(2003)

Standard Test Methods for Coated and Laminated Fabrics for Architectural Use

Standard Details

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 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 Force	16
Breaking Strength After Crease Fold	17
Elongation at Break	18
Fabric Trapezoid Tear Force	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 The values stated in either SI or inch-pound units are to regarded separately as the standard. Within the text, the inch-pound units are shown in parentheses. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other.

1.6 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.
