These compatible gas groups are determined according to practical criteria defined in ISO 14456.These criteria are based on certain physical, chemical, toxic and corrosive properties of the gases. In particular, the flammability in air and the oxidizing ability are considered in this document.One of the potential complications that prompted the development of this document
