1.1 This specification recognizes the complexity of structural glued products. Consequently, this specification covers both specific procedures and statements of intent that sampling and analysis must relate to the specific product. 1.2 This specification was developed in the light of currently manufactured products as defined in 1.3 Details of manufacturing procedures are beyond the scope of this specification. 1.4 This specification primarily
considers end use in dry service conditions, such as with most
protected framing members, where the average equilibrium moisture
content for solid-sawn lumber is less than 16 %. The conditioning
environment of 1.5 The performance of structural
composite lumber is affected by wood species, wood element size and
shape, and adhesive and production parameters. Therefore, products
produced by each individual manufacturer shall be evaluated to
determine their product properties, regardless of the similarity in
characteristics to products produced by other manufacturers. Where
a manufacturer produces product in more than one facility, each
production facility shall be evaluated independently. For
additional production facilities, any revisions to the full
qualification program in accordance with this specification shall
be approved by the independent qualifying agency.
1.6 This specification is intended to provide manufacturers, regulatory agencies, and end users with a means to evaluate a composite lumber product intended for use as a structural material. 1.7 This specification covers initial qualification sampling, mechanical and physical tests, analysis, and design value assignments. Requirements for a quality-control program and cumulative evaluations are included to ensure maintenance of allowable design values for the product. 1.8 This specification, or parts thereof, shall be applicable to structural composite lumber portions of manufactured structural components. 1.9 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. 1.10 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. |
