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
38、 averaged minimum wall thickness is due to core shift which is a normal occurrence found in fittings that are injectionmolded. When core shift occurs, the 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 ave
39、raged 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 applies 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
40、wye fitting) thenthe single wall thickness reading shall not be more than 10% below the averaged minimum value shown in Table 1.B Not applicable for these nominal sizes.D2665 143std. dev.!5F(PS2 2(PS! 2 /NN 21 G1/2N = 116.3.1.4 The 15 % requirement is calculated as follows:Avg2LCL!/Avg! 3100#15% (3)
