ASTM E773-01

1.1 This test method covers procedures for testing the performance of preassembled permanently sealed insulating glass units against accelerated weathering.

1.2 This test method is applicable only to sealed insulating glass units, with one or two airspaces, fabricated for vision glass areas for use in buildings, such as sliding doors, windows, wall systems, and picture windows.

1.3 The unit construction used in this test method contains dimensions that are an essential component of the test. Deviations of glass or airspace sizes, or both, will affect the test results.

1.4 This test method is not applicable to sealed insulating glass units that are constructed from exterior vision materials other than glass.

1.5 The values stated in SI units are to be regarded as the 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 and health practices and determine the applicability of regulatory limitations prior to use. A specific hazard statement is given in Note 2.

This test method is intended to provide a means for evaluating the durability of the sealing system of sealed insulating glass units. A round-robin test has been conducted, and additional data are being collected. The suitability of these test methods will be further evaluated as the analysis of test results is completed.
