Scope

This outline is applicable to the type evaluation of pressure type sulfur hexafluoride (SF6) gas density controllers (also known as gas density relays or gas density monitors, hereinafter referred to as "controllers") with measurement elements made of spring tubes or bellows, a measurement range of (-0.1 to 0.9) MPa or (-0.1 to 0.5) MPa, and a nominal diameter of 100 mm for the instrument housing. The working medium is sulfur hexafluoride gas, and the controllers are classified under the code 12320000 in the Measuring Instruments Classification and Coding System.
