Significance and Use | ||
4.1 Wood adhesive performance and cost is often related to the solids level (nonvolatile content). 4.2 This test method determines the apparent nonvolatile content for urea-formaldehyde resins. |
||
1. Scope | ||
1.1 This test method covers the determination of the apparent nonvolatile content of urea-formaldehyde resin solutions intended for use as wood adhesives. Due to the chemical nature of such resins, the nonvolatile content determined varies markedly according to the type of test used. In order to minimize this condition, this test method is designed to yield reasonably uniform agreement among different laboratories testing specimens from the same sample. 1.2 The values stated in SI units are to be regarded as the 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, health, and environmental 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. |
