ASTM F1123-87(2015)

Standard Specification for Non-Metallic Expansion Joints

ABSTRACT
This specification provides the minimum requirements for construction, materials, performance, and dimensions of arch-type non-metallic expansion joints. Expansion joints shall be fabricated with an elastomeric tube reinforced with multiple plies of woven cloth or tire cord covered with synthetic rubber. The inner tube shall be a natural rubber, synthetic rubber, or blend of synthetic rubber. The woven cloth or tire cord shall be nylon, polyester, fiberglass, or aramid, and shall not be cotton. The reinforcing fabric shall be impregnated with a compatible friction stock. Additional reinforcement to the fabric may be provided in the body of the expansion joint and may be solid metal rings or wire embedded in the synthetic rubber. Body rings, if used, must be welded before being installed in the expansion joint body. All expansion joints shall be manufactured with a cover of Hypalon or Neoprene (Chloroprene). The requirements for (1) integral rubber and fabric flanges, (2) floating metal flanges, (3) arches, (4) metallic flanges, (5) retaining rings, and (6) expansion joint cover and body. All expansion joints shall be designed for the specified pressure requirement. Performance requirements for single arch expansion movement and multiple arch-joint movement, as well as the pressure rating, are specified. The following tests shall be performed if required: burst test for prototype testing, hydrostatic test for production testing, and flame resistance test.
SCOPE
1.1 This specification provides the minimum requirements for construction, materials, performance, and dimensional requirements of arch-type non-metallic expansion joints.  
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.3 The following safety hazards caveat pertains only to the test method described in this specification. 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.
