Standard Test Method for Accelerated Aging of Environmentally Controlled Dynamic Glazing

Importancia y uso:

4.1 ECDG perform a number of important functions in a building envelope including: reducing the solar energy heat gain; providing a variable visual connection with the outside world; enhancing human comfort (heat gain), security, illumination, and glare control; providing for architectural expression, and (possibly) improving acoustical performance. It is therefore important to understand the relative serviceability of these glazings.

4.2 This test method is intended to provide a means for assessing the relative serviceability of ECDGs, as described in Section 1.

4.3 The test method is intended to simulate in-service use and accelerate aging of the environmentally controlled dynamic glazings.

4.4 Results from these tests cannot be used to predict the performance over time of in-service units unless actual corresponding in-service tests have been conducted and appropriate analyses have been conducted to show how performance can be predicted from the accelerated aging tests.

4.5 The procedure in this test method includes environmental test parameters that are typically used in weatherability tests by standards organizations and are realistic for the intended use of large-area ECDG units.
