Subdivision 6: medium pressure range, compressed gases from 35 bar up to and including 250 bar; Subdivision 7: hiah pressure range, above 250 bar Each category is composed of Merent Sub-diWions, a supports combustion (oxidizing gas having an oxidant potential equal to or less than that of ai

For corrosiveness, gases are divided into 4 subdivisions:
23、Subdivision O non-corrosive; Subdivision 1: non-halogen acid forming; Subdivision 2: basic; Subdivision 3: halogen acid forming. 6.6 Designation of the code This code is called E“rsc code: F: E fortoxicity; for fire potentia S: for gas state, defining the physical state of the contents in the cylind

Most of these gases may be Nied at hig
26、her pressure and consequently the relevant digit 7 or 8 shall then be used. For liquefied gases the third digit used in this standard is O or 1 (depending on the pressure). Most of these gases may be used with liquid withdrawal and consequently the relevant digit 2 shall then be used (irrespective o
27、f the pressure). where E50 values correspond to 1 h exposure and mortality in 14 days and with p.p.m.V corresponding to the parts per million by volume.
