Which ASTM standard is NOT applicable to medical-surgical vacuum system piping made from hard-drawn seamless copper tube?

ASTM B597 is not applicable to medical-surgical vacuum system piping made from hard-drawn seamless copper tube, mainly because it specifically pertains to copper and copper alloys used in the construction of heat exchangers, rather than piping systems for medical gas applications. Therefore, this standard does not cover the material properties or construction methods relevant to vacuum systems used in healthcare settings.

In contrast, the other standards mentioned serve different purposes within the medical gas piping realm. ASTM B88 pertains to the specifications for seamless copper water tubes, which can be relevant given that medical vacuum systems may utilize similar materials. ASTM B280 focuses on the requirements for copper tube and fittings for air conditioning and refrigeration applications, which can also overlap with the materials used in medical tubing. ASTM B819 outlines the copper piping for medical gas systems, making it directly applicable to the mentioned systems. Each of these applicable standards emphasizes the quality and safety of materials pertinent to medical applications, while ASTM B597 does not align with the particular specifications required for medical-surgical vacuum system piping.
