Significance and Use
5.1 Compliance with national and local air emission regulations create the need to determine volatile organic compound (VOC) emissions from adhesive-bonded structural wood products.
5.2 This method has been used to estimate the types and amounts of certain VOC that are emitted during production operations.
5.3 The method was originally developed to measure the methanol, formaldehyde, and phenol emitted in a laboratory setting that is designed to simulate the hot pressing, and post pressing conditions of hot stacking and cool down period for exterior plywood and laminated veneer lumber (LVL) processes. This current method generalizes the concept for adhesive-bonded wood products.
1.1 This test method provides a method for the collection of volatile organic compounds (VOC) that are emitted during the manufacture of engineered wood products using a laboratory environment designed to simulate a defined production process. The method is used for the determination of the amounts of methanol, formaldehyde, phenol and other VOC that may be emitted during conditions designed to simulate production such as hot pressing, the conditions of ‘hot stacking’ and ‘cool-down’ that occurs post-press.
1.2 The test method was originally developed to measure certain VOC from exterior plywood meeting Voluntary Product Standard PS 1–09 and structural composite lumber products such as laminated veneer lumber (LVL) meeting Specification . Both of these product types are typically manufactured using phenol-formaldehyde resin based adhesives that meet Specification .
1.3 The test method is suitable for many types of wood products bonded with adhesives.
1.4 This test method is specific for collecting VOC during simulated production of wood products and is not designed to determine general organic emissions from all indoor materials or sources.
1.5 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Some specific hazards statements are given in Section on Hazards.
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
