If one or two

26、fail, additional testing shall beconducted in accordance with 6.3.1.2. If all three fail, thesample does not meet the PS requirement.6.3.1.2 Pipe Stiffness and Lower Confidence LimitIn theevent that one or two of the specimens tested in 6.3.1 fail tomeet the minimum PS requirement, the average pipe

Alternatively, if the LCL exceeds the minimum PSrequirement in Table 3, but is not within 15 % of the average,the sample meets the requirements of the pipe stiffness testing.The eleven specimens include the three tested under 6.3.

Use a 12-lb (5-kg) tup for testing pipesizes 4 in. and smaller and a 20-lb (10-kg) tup for pipe largerthan 4 in. T

33、est fittings with a 12-lb (5-kg) Tup. Test couplingscemented to short pieces of pipe and allowed to dry for 24 h.For fittings larger than 4-in, a symmetric section cut from thehub or body with a minimum centerline length of 2 in. shall bepermitted to be used rather than the entire fitting.D2665 1426

34、.4.1 Test 10 specimens. When 9 or 10 specimens pass,accept the lot. When 2 or more specimens fail, test 10additional specimens. When 17 of 20 specimens tested pass,accept the lot. When 4 or more of 20 specimens tested fail, test20 additional specimens. When 32 of 40 specimens pass,accept the lot. Wh

35、en 9 or more of 40 specimens fail, the lotdoes not meet the requirements of this specification.6.4.2 Failure in the test specimens shall be shattering or anycrack or break extending entirely through the pipe wall andvisible to the unaided eye.TABLE 1 Dimensions and Tolerances for Fitting Sockets for

41、. An averaged minimum is derived by adding two wall thicknesses that are directly opposite eachother and dividing the result by 2. The reason for an averaged minimum wall thickness is due to core shift which is a normal occurrence found in fittings that are injectionmolded. When core shift occurs, t

42、he result is a pair of high and low wall thickness readings. The average of the high and the low wall thickness readings must equal orexceed the averaged minimum value shown in Table 1. The low wall thickness reading shall not be more than 10% below the averaged minimum value shown in Table1. This a

43、pplies to any point on the fitting (hub, body, or spigot). In cases where there is no opposite side (as in the case of a portion of the branch of a wye fitting) thenthe single wall thickness reading shall not be more than 10% below the averaged minimum value shown in Table 1.BNot applicable for thes
