QW462.3弯曲试验宽度尺寸范围

happytree

If the pipe being tested has a diameter of NPS 4 (DN 100) or less,
the width of the bend specimen may be 3⁄4 in. (19 mm) for pipe
diameters NPS 2 (DN 50) to and including NPS 4 (DN 100). The
bend specimen width may be 3⁄8 in.

可以理解为 NPS 4 (DN 100)~NPS 2 (DN 50) 选取的试样宽度为19mm
请教这里的NPS 4 (DN 100)具体的范围是多少啊？
