ASTM-E1089 › Standard Test Method for Water Penetration of Flat Plate Solar Collectors by Uniform Static Air Pressure Difference (Withdrawn 2013)
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 This test method covers the determination of the resistance of flat plate solar collectors to water penetration when water is applied to their outer surfaces with a static air pressure at the outer surface higher than the pressure at the interior of the collector.
1.2 This test method is applicable to any flat plate solar collector.
1.3 The proper use of this test method requires a knowledge of the principles of pressure and deflection measurement.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 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. Specific precautionary information is contained in Section 6.
Significance and Use
The rain spray test described in 8.1 as Method A is based upon Test Method E 331
Water leakage due to joint expansion can be influenced by several factors, including: the specific collector design and materials used, the test specimen temperature, and the water spray temperature (Note 1), in addition to the pressure differential. The temperature conditions will vary in outdoor exposure. The test temperatures should be selected to be representative of outdoor conditions where the collectors will be used.
Note 1—Water spray temperatures are likely to range from 4.5°C to 29.4°C (40 to 85°F).
