Standard Test Methods for
Coated and Laminated Fabrics for Architectural Use1

This standard is issued under the fixed designation D 4851; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

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 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
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 appro
