organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

ISO 13338:2022(E)
Introduction
ISO 5145 specifies the dimensions of different valve outlets for different compatible gas groups. 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 gas corrosiveness is considered in this document.
The aim of this document is to assign a classification category for each gas that takes into account the
tissue corrosiveness of the gas for skin, eyes and the respiratory tract as well as the potential for a
corrosiveness related acid/base chemical reaction.
For gas mixtures containing corrosive components, a calculation method based on the additivity
[3]
method of the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) is
proposed.
However, for gas mixtures containing corrosive gas components, some valve outlets standards require
the use of the corrosive category regardless of the corrosive gas concentration.

tissue corrosiveness
ability of a gas to damage or destroy living tissues (eyes, skin and mucous
membranes)
Note 1 to entry: It corresponds to GHS hazard class “Skin corrosion/irritation” Cat. 1, 1A, 1B or 1C, or to GHS
hazard class “Serious eye damage/eye irritation”, Cat. 1.
3.2
irritant
property of a gas which can cause a temporary reaction to the skin, eyes and mucous membranes
Note 1 to entry: It corresponds to GHS hazard class “Skin corrosion/irritation”, Cat. 2, or to GHS hazard class
“Serious eye damage/eye irritation”, Cat. 2.
4 Classification
Gas cylinder connections should take into account all aspects of corrosiveness as reflected in the
subdivisions of the C code of the FTSC code (which includes tissue corrosiveness and acid/base chemical
reactivity). The subdivisions of the FTSC code are given below and repeated in the footer of Table 1:
— 0: non-corrosive;
— 1: non-halogen acid forming;
— 2: basic;
— 3: halogen acid forming.
