1.1 This test method covers testing procedures for architectural joint systems. This test method is intended for the following uses for architectural joint systems:
1.1.1 To verify movement capability information supplied to the user by the producer,
1.1.2 To standardize comparison of movement capability by relating it to specified nominal joint widths,
1.1.3 To determine the cyclic movement capability between specified minimum and maximum joint widths without visual deleterious effects, and
1.1.4 To provide the user with graphic information, drawings or pictures in the test report, depicting them at minimum, maximum, and nominal joint widths during cycling.
1.2 This test method is intended to be used only as part of a specification or acceptance criterion due to the limited movements tested.
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.4 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.
