(Test Method)Standard Test Method for Qualitative Tests for the Presence of Water Repellents and Preservatives in Wood Products
Standard Test Method for Qualitative Tests for the Presence of Water Repellents and Preservatives in Wood Products
SIGNIFICANCE AND USE
3.1 Although chlorinated phenol-treated wood has become less common due to environmental concerns, repellent-treated wood is commonly specified in construction. This test method provides a means to verify the presence of a significant level of water repellent protection.
SCOPE
1.1 This test method covers simple qualitative field or laboratory tests to determine water repellency or the presence of chlorinated phenol2 preservative chemicals in wood products that are specified to be water repellent preservative treated.
1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.3 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.
1.4 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.
