5.1 This test method is a general procedure for testing architectural glass products under uniform static loads.

5.2 Loads on glass in windows, curtain walls, and doors may vary greatly in magnitude, direction, and duration. An understanding of wind loads on the building is required for selection of test loads and interpretation of results with respect to expected exposure at a particular site.

5.3 A thorough understanding of the variations of the strength of glass and the nature of loading is required to interpret results of this test method.

5.4 The proper use of this test method requires a knowledge of the principles of pressure, deflection, and strain measurement.

1.1 This test method is a general test procedure for load tests of glass subjected to uniform static loads. It is applicable for test protocols involving specified loads, load durations, and loading rates.

1.2 This test method is applicable to architectural flat glass of various types; for example, annealed, heat-strengthened, fully tempered, laminated, insulating, and combinations thereof.

1.3 This test method describes a process of applying specific test loads to glass. The test may be conducted using a standard test frame specified herein or a test frame of the user's design.

1.4 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.

1.5 This standard does not purport to address all of the safety problems, 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. For specific precautionary statements see Section 7.

1.6 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.
