These compatible gas groups are determined according to practical c
28、riteria defined in ISO 14456.These criteria are based on certain physical, chemical, toxic and corrosive properties of the gases. In particular, the tissue corrosiveness is considered in this document.The aim of this document is to assign a classification category for each gas that takes into accoun
29、t the corrosiveness for skin, eyes and the respiratory tract of the gas.For gas mixtures containing corrosive components, a calculation method based on the additivity method of the GHS is proposed.However, for gas mixtures containing corrosive gas components, some valve outlets standards require the
30、 use of the corrosive category regardless of the corrosive gas concentration.
