1.1 This specification establishes the requirements for two wall thickness schedules of specially cleaned, straight lengths of seamless copper tube, identified as Types K and L, suitable for medical gas systems. The tube shall be installed in conformance with the requirements of the National Fire Protection Association (NFPA) Standard 99, Gas and Vacuum Systems (NFPA) Standard 99C, Standard for Hypobaric Facilities (NFPA) Standard 99B, and Canadian Standards Association (CSA) Standard Z 305.1/Z 7396.1, Nonflammable Medical Gas Piping Systems.
Note 1Types K and L tube are defined in Specification B 88.
Note 2Drawn temper tube is suitable for use with capillary (solder joint) fittings for brazing.
1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units, which are provided for information only and are not considered standard.
This specification establishes the requirements for two wall thickness schedules of specially cleaned, straight lengths of seamless copper tube, identified as Types K and L, suitable for medical gas systems. The product shall be manufactured by such hot working necessary to convert the billet to a tubular shape and cold worked to the finished size. Seamless copper tube for medical gas systems shall be furnished in the H58 (Drawn General Purpose) temper. Tension test and Rockwell hardness test shall be performed to determine the tube's tensile strength and hardness, respectively. Eddy-current test, a nondestructive test, shall be performed as well. The tubes used for medical gas systems shall be cleaned by any of the following recommended methods: alkaline washing, steam solvent washing, steam detergent washing, steam washing, vapor degreasing, and refrigerant degreasing.
