ASME A112.18.1-2018/CSA B125.1-18 Plumbing supply fittings Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application. 1.5 SI units are the units of record in Canada. In this Standard, the inch/pound units are shown in parentheses. The values stated in each measurement system are equivalent in application; however, each system is to be used independently. Combining values from the two measurement systems can result in nonconformance with this Standard.
