38、special machining. 9 Elastomeric Parts Tests 9.1 An elastomeric part used to provide a seal shall have the following properties when tested as specied in the Standard for Gaskets and Seals, UL 157: a) For silicone rubber (having poly-organo-siloxane as its constituent characteristic), a minimum tens
39、ile strength of 500 psi (3.4 MPa) and a minimum ultimate elongation of 100 percent. b) For natural rubber and synthetic rubber other than silicone rubber, a minimum tensile strength of 1500 psi (10.3 MPa) and minimum ultimate elongation of 150 percent; or a minimum tensile strength of 2200 psi (15.2
40、 MPa) and a minimum ultimate elongation of 100 percent. c) Those properties relating to maximum tensile set; minimum tensile strength and elongation after oven aging; and hardness after oven aging, all as specied in UL 157. The maximum service temperature used to determine the oven time and temperat
41、ure for oven aging is 60C (140F). 9.2 The Standard for Gaskets and Seals, UL 157, provides for the testing of either nished elastomeric parts or sheet or slab material. Sheet or slab material is to be tested when the elastomeric parts are O-rings having diameters of less than 1 inch (25.4 mm). The m
42、aterial tested is to be the same as that used in the product, regardless of whether nished elastomeric parts or sheet or slab material is tested. 10 Leakage Test 10.1 A rubber gasketed tting assembly with pipe shall withstand for 1 minute, without leakage, an internal hydrostatic pressure of two tim
43、es its rated pressure. No leakage of the tting shall occur as the pressure is increased to the test pressure. 10.2 Leakage tests are to be conducted on ttings assembled onto sections of pipe at least 15 inches (381 mm) in length. The pipe ends to be joined by the tting are to be prepared and assembl
44、ed as specied by the manufacturer. The pipe ends of the test assembly are to be closed to provide for the assembly to be pressurized. The pressure is to be increased to twice the rated pressure and held for 1 minute. AUGUST 1, 2013 RUBBER GASKETED FITTINGS FOR FIRE-PROTECTION SERVICE - UL 213 6UL CO

47、 pipe assemblies in accordance with the methods of 10.2, and with the pressure specied in 11.1. 12 Bending Moment Tests 12.1 General 12.1.1 The tting and pipe joint assembly shall not leak or rupture when subjected to the specied bending moment as determined by 12.1.3. 12.1.2 The pipe ends to be joi
48、ned by the tting are to be prepared and assembled as specied by the manufacturer. The assembly is to be pressurized to rated pressure. 12.1.3 The required bending moment is calculated based on twice the weight of water lled pipe over twice the maximum distance between pipe supports specied in the St
49、andard for Installation of Sprinkler Systems, ANSI/NFPA 13. Table 12.1 contains bending moment requirements for Schedule 5, 10, 30 and 40 steel pipe. The required bending moment for tting sizes and pipe combinations not specied in Table 12.1 is to be calculated according to the following formula: where: M is the required bending moment (lbft); w is the running weight of water lled pipe (lb/ft); and L is two times l, maximum hanger spacing (ft).
