See Elastomeric Parts Test, Section 9

30、. PERFORMANCE 8 General 8.1 Representative samples of each class and size of pipe and couplings shall be subjected to the tests specied in Sections915. 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

31、for Gaskets and Seals, UL 157: a) Minimum tensile strength 2000 pounds per square inch (psi) (13.8 MPa). b) Minimum ultimate elongation 300 percent 1 to 4 inches (25.4 to 102 mm). c) Permanent set of 3/16 inch (4.8 mm) when 1 inch (25.4 mm) marks are stretched to 3 inches (76.2 mm), held for 2 minut

32、es and measured 2 minutes after release. d) Those properties relating to 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 temperature for oven aging is 60C (140F). 10

33、 Hydrostatic Pressure Test 10.1 Pipe and couplings (if provided) shall withstand for 5 seconds without rupture or weepage an internal hydrostatic pressure of four times the rated working pressure based on the minimum wall thickness of the pipe. 10.2 Three samples of each pressure class and size of p

34、ipe and couplings are to be prepared for hydrostatic pressure for short-time rupture strength in compliance with the Standard Test Method for Resistance to Short-Time Hydraulic Pressure of Plastic Pipe, Tubing, and Fittings, ANSI/ASTM D1599. The minimum wall thickness, average wall thickness (minimu

35、m of six points), outside diameter, and length of the samples are to be measured and recorded. The test pressure is to be determined based on the calculated hoop stress for the minimum wall thickness and minimum test pressure (four times rated working pressure) using the measured minimum wall thickn

36、ess. For sizes up to and including 8 inches (203 mm), the sample length (between end caps) is to be at least ve times the nominal diameter, and for larger sizes, the length is to be at least three times the nominal diameter. 10.3 The ends of the sample are to be sealed with gaskets or end caps. The

37、sample is then to be connected to the hydrostatic-pressure testing equipment and all air is to be expelled from the pipe or tting. The internal water pressure is to be increased at a uniform rate until the calculated test pressure has been attained. The calculated test pressure is to be held for 5 s

38、econds. The pressure then is to be increased until rupture or weepage occurs. See 17.1. The rate at which the pressure is increased is to be adjusted within the range of 50 30 psig (345 207 kPa) per second so that rupture or weepage occurs in not less than 60 seconds after the initial application of

39、 pressure.

40、h clearances determined by the manufacturers tolerances, shall not leak and shall not exhibit damage that impairs the intended operation when subjected to a hydrostatic pressure of twice the rated pressure. 11.2 Pipe to be used in each test is to be representative of each class and size. At least on

41、e joint is to be machined to the maximum clearance allowed by the manufacturers tolerances. A test line is to be assembled of at least ve lengths of pipe with couplings and sealing gaskets, in compliance with the manufacturers installation instructions. At least two joints, including the maximum cle

42、arance joint, are to be deected to the maximum deection rated by the manufacturer. The ends of the test line are to be restrained to conne longitudinal separation at the joints. Four tests of single joints are capable of being conducted in lieu of the test on a single line. 11.3 The test line is to

43、be connected to the hydrostatic pressure testing equipment and all air is to be expelled from the system. The water pressure is to be increased in 50 psig (345 kPa) increments until twice the rated pressure is attained. At each increment of pressure increase, measurements are to be made of distortio

44、n at each joint, protrusion of gasket material (if any) or other factors that cause leakage after continued use of the pipe in service. During the test, the pressure is not to be increased to the next increment until the line and connections have become stable, as evidenced by no further movement of

45、 gasket material. 11.4 After the test pressure has been increased to twice the rated pressure, the test pressure is to be decreased to 0 psig, while observations are made for leakage. Then, the pressure is again to be slowly increased to twice the rated pressure while observations are made for leaka

46、ge. 12 Assembly Test 12.1 Pipe joints made with minimum clearances between the pipe spigot and bell or coupling, determined in accordance with the manufacturers tolerances, shall, when assembled as specied in 12.2, exhibit no damage to gaskets, pipe, or coupling sections. Cut or torn gasket material

47、s and chipped or broken pipe or coupling sections do not comply with the requirement. 12.2 Representative samples of each class and size of pipe and couplings are to be machined as required. Two pipe sections are to be joined together in accordance with the manufacturers instructions, using a nonmin

48、eral base lubricant, or the equivalent, and installation tools such as pike bars and jack and chain .
