Lists acceptable materials that comply with ASTM specifications:

For instrument manifold systems, gauge isolation, and small-bore connections, MSS SP-99 is the definitive standard.

ISO 17292 covers metal ball valves for petroleum, petrochemical, and allied industries. MSS SP-99 is narrower (needle/manifold valves). However, many manifold valves now also comply with ISO 15848 for fugitive emissions. mss sp99 pdf

: Covers operational ratings reaching a maximum of 15,000 psi (103.4 MPa) at 100°F (38°C).

(revised as MSS SP-99-2023 ) is a standard practice published by the Manufacturers Standardization Society (MSS)

The standard mandates that each valve must have a clearly marked pressure rating at 100°F (38°C), with de-rating factors for higher temperatures. For example: It primarily covers steel and alloy valves with

: Applicable designs include needle valves, ball valves, plug valves, check valves, manifold valves, and packless valves. Excluded Scope
