ASTM E2190-02 Standard Specification for Insulating Glass Unit Performance and Evaluation

1.1 This specification is applicable to preassembled permanently sealed insulating glass units with one or two airspaces and preassembled insulating glass units with capillary tubes intentionally left open.

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

1.3 The qualification of test specimens is based on frost/dew point and on the absence of fog after the specified test durations.

1.4 Qualification under this specification is intended to provide a basis for evaluating the durability of sealed insulating glass units.

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

1.6 This specification does not cover other physical requirements such as appearance, thermophysical properties, heat and light transmission, and glass displacement.

Note 1—Sealed 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 C 1369, Guide C 1249, and Test Method C 1265.

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 requirements prior to use.
