The values stated in eachsystem are not exact equivalents; therefore, each system mustbe used independently of th

10、e other. Combining values from thetwo systems may result in nonconformance with the specifi-cation. The inch-pound units shall apply unless the “M”designation (SI) of the product specification is specified in theorder.NOTE 1The dimensionless designator NPS (nominal pipe size) hasbeen substituted in
