    Significance and Use

    This test method is intended to provide a means for testing the resistance to fogging in sealed insulating glass units.

    This test method is also intended to provide a means for testing the resistance to fogging caused by components in the interior of the unit. These interior components include, but are not limited to, suspended or applied films, decorative components, muntins, and coatings.

    1. Scope

    1.1 This test method covers procedures for testing the resistance to fogging of preassembled permanently sealed insulating glass units or insulating glass units with capillary tubes intentionally left open.

    1.2 This test method is applicable only to sealed insulating glass units that are constructed with glass.

    1.3 This test method is applicable to both double-glazed and triple-glazed insulating glass units; for triple-glazed insulating glass units where both of the outer lites are glass and the inner lite is either glass or a suspended film.

    1.4 The unit construction used in this test method contains construction details that are essential components of the test. Different types of glass, different glass thicknesses and different airspace sizes may affect the test results.

    1.5 This test method is not applicable to sealed insulating glass units containing a spandrel glass coating due to testing limitations.

    1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

    1.7 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.
