Standard Specification for Insulating Glass Unit Performance and Evaluation
1.1 This specification covers preassembled permanently sealed insulating glass units with one or two cavities and preassembled insulating glass (IG) units with capillary tubes intentionally left open or closed.
1.2 This specification is applicable only to insulating glass units that are constructed with glass or suspended film.
1.3 This specification 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 middle lite is either glass or a suspended film.
1.4 The qualification of test specimens is based on frost/dew point and on the absence of fog after the specified test durations.
1.5 The qualification of argon gas-filled test specimens is based on maintaining the specified argon gas amounts before and after testing to Test Method E2188.
1.6 Qualification under this specification is intended to provide a basis for evaluating the durability of insulating glass units.
1.7 This specification is not applicable to insulating glass units containing a spandrel glass coating due to test method limitations.
1.8 This specification does not cover other physical requirements such as appearance, thermophysical properties, heat and light transmission, and glass displacement.
Note 1: Insulating glass units qualified according to this specification are not necessarily suitable for structurally glazed applications. Factors such as sealant longevity when exposed to long term ultraviolet light and the structural properties of the sealant must be reviewed for these applications. For more information on the requirements for structural sealant glazing applications, refer to Specification C1369, Guide C1249, and Test Method C1265.
1.9 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.
1.10 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.
1.11 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.
