1.1 This specification covers the procedures to establish a performance rating for wood-plastic composite (WPC) deck boards. This specification also defines the procedures to establish a performance rating for WPC guards and handrails. The purpose of this specification is to establish the basis for code recognition of these products or systems in exterior applications where combustible construction is allowed (see X1.1). Note 1: While WPCs may contain wood fiber, the presence of
wood fiber in the composite is not required by this standard. Other
lignocellulosic materials may be used. For WPC deck boards and
guardrail systems evaluated according to this standard, the
structural, physical, and fire attributes may or may not exhibit
similarity to those of wood due to the presence, type, and quantity
of plastic(s) in the composite. WPCs should not be assumed to
behave similarly to wood. For example, to address the influence of
plastic in the composite, special considerations in the standard
address sensitivity to temperature, ultraviolet (UV) exposure, and
freeze-thaw resistance.
1.2 Deck boards, guards, and handrails covered by this specification are permitted to be of any code compliant shape and thickness (solid or non-solid). Note 2: While WPCs are produced in a broad range of ratios of
fiber to resin it is recognized that the performance requirements
in this specification are valid for any material or combination of
materials used as deck boards, guards, or handrails. For products
made primarily from resin, or for products that exhibit highly
plastic properties (for example, more than 3 % strain without
rupture in a standard flexural test under ambient conditions),
users are directed to Specification D6662 for additional guidance.
1.3 A deck board, and a deck board used as a stair tread, are assigned a span rating indicating its ability to comply with model code specified functions identified for its specific end use. A guard or handrail is recognized for its ability to meet minimum code requirements specified in the appropriate model building code. 1.4 Details of manufacturing processes may be proprietary and are beyond the scope of this specification. 1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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 requirements prior to use. 1.7 Table of Contents:
