4.1 Types of architectural joint systems included in this test method are the following:
4.1.5 Preformed foams and sponges:
4.1.5.1 Self-Expanding, and
4.1.6 Fire barriers:
4.1.6.1 Used as joint systems, and
4.1.6.2 Used as a part of the joint system, and
4.1.7 Elastomeric membrane systems:
4.1.7.1 With nosing material(s), and
4.1.7.2 Without nosing material(s).
4.2 This test method will assist users, producers, building officials, code authorities, and others in verifying some performance characteristics of representative specimens of architectural joint systems under common test conditions. The following performance characteristics are verifiable:
4.2.1 The maximum joint width,
4.2.2 The minimum joint width, and
4.2.3 The movement capability.
4.4 This test method does not provide information on:
4.4.1 Durability of the architectural joint system under actual service conditions, including the effects of cycled temperature on the joint system,
4.4.2 Loading capability of the system and the effects of a load on the functional parameters established by this test method,
4.4.3 Rotational, vertical, and horizontal shear capabilities of the specimen,
4.4.4 Any other attributes of the specimen, such as fire resistance, wear resistance, chemical resistance, air infiltration, watertightness, and so forth, and
4.4.5 Testing or compatibility of substrates.
4.5 This test method is only to be used as one element in the selection of an architectural joint system for a particular application. It is not intended as an independent pass/fail acceptance procedure. In conjunction with this test method, other test methods are to be used to evaluate the importance of other service conditions such as durability, structural loading, and compatibility.
