ASME B16.15:2018 pdf download.Cast Copper Alloy Threaded Fittings Classes 125 and 250.

2.5 Time of Purchase, Manufacture, or InstaLLation

The pressure—temperature ratings in this Standard are applicable upon its publication to all fittings within its scope that

otherwise meet its requirements. For unused fittings maintained in inventory, the manufacturer of the fittings may certify

conformance to this edition provided it can be demonstrated that all requirements of this edition have been met. Where such

components were installed in accordance with the pressure-temperature ratings of an earlier edition of this Standard, those ratings are applicable except as may be governed by the applicable code or regulation.

2.6 User AccountabiLity

This Standard cites responsibilities that are to be assumed by the fitting user in the areas of the temperature at which the

pressure rating is taken.

2.7 Service Conditions

Criteria for selection of materials suitable for particubr fluid service are not within the scope of this Standard.

3 PRESSURE-TEMPERATURE RATiNGS

3.1 GeneraL

Pressure-temperature ratings for these pipe fittings are shown in Table 3.1-1. All pressures are gage.

3.2 Rating

Pressure—temperature ratings are independent of the contained fluid and are the maximum allowable pressures at the tabulated

temperatures. Intermediate ratings may be obtained by linear interpolation between the temperatures shown.

The temperature shown for the corresponding pressure rating shall be the material temperature ot the pressure- retaining structure. It may be assumed that the material temperature is the same as the fluid temperature. Use of a pressure rating at a material

temperature other than that of the contained fluid is the responsibility of the user and subject to the requirements of any

applicable codes and regulations.
