1.1 This test method covers testing procedures for architectural joint systems. This test method is intended for the following uses:

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 acceptable standard units of measure are SI units and the equivalent inch-pound units are expressed in parenthesis.

1.4 This standard does not purport to address the safety problems 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.
