This specification contains various requirements that, with the exception of Section 5 and Section 10, are mandatory requirements to the following ASTM nickel and nickel alloy, longitudinally welded piping specifications:

B464/B464M: Welded UNS N08020 Alloy Pipe
B514: Welded Nickel-Iron-Chromium Alloy Pipe
B517: Welded Nickel-Chromium-Iron-Alloy (UNS N06600, UNS N06603, UNS N06025 and UNS N06045) Pipe
B619/B619M: Welded Nickel and Nickel-Cobalt Alloy Pipe
B673: UNS N08904, UNS N08925, and UNS N08926 Welded Pipe
B675: UNS N08367 Welded Pipe
B705: Nickel-Alloy (UNS N06625, N06219, and N08825) Welded Pipe
B723: Ni-Cr-Mo-Co-W-Fe-Si Alloy (UNS N06333) Welded Pipe
B725: Welded Nickel (UNS N02200/UNS N02201) and Nickel Copper Alloy (UNS N04400) Pipe

One or more of the test requirements of Section 5 apply only if specifically stated in the product specification or in the purchase order.

In case of conflict between a requirement of the product specification and a requirement of this general specification, only the requirement of the product specification needs to be satisfied.

The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.
