实施绝热材料终饰材室外暴露测试的试验方法

Standard Test Method for Conducting Exterior Exposure Tests of Finishes for Thermal Insulation

适用范围:<p id="s00014">Both physical and chemical changes may occur from weather exposure, and these changes affect performance properties, service life, and maintenance schedules. For this reason, tests of properties relating to performance should be made both before and after specific periods of outdoor exposure.</p> <p id="s00015">This test method recognizes that differing geographical locations, environmental conditions, differences between surface temperatures and ambient temperatures, and test durations may have extremely varied effects upon the test results.</p> <p id="s00016">This test method is to be used for comparative qualitative testing.</p><p>1.1 This test method covers out-of-doors exposure testing of finishes that are normally field-applied to thermal insulation which may include joints or joint sealants, or both. Such exposure may be essential prior to the determination of certain physical properties. This test method may also indicate compatibility problems between the joint sealant and the finish as well as the ability of the finish to span a dry joint. This test method is not intended to evaluate mildew resistance, efflorescence, or chemical resistance. Note 1For testing free plastic films, see Practice D 1435.</p></p><p>1.2 This test method does not prescribe the method of application, test duration, or inspection intervals.</p><p>1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information only.</p><p>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.</p>
