Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

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.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

on the ISO list of patent declarations received (see www .iso .org/ patents).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to the

World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www .iso .org/

iso/ foreword .html.

This document was prepared by Technical Committee ISO/TC 58, Gas cylinders, Subcommittee SC 2,

Cylinder fittings, in collaboration with the European Committee for Standardization (CEN) Technical

Committee CEN/TC 23, Transportable gas cylinders, in accordance with the Agreement on technical

cooperation between ISO and CEN (Vienna Agreement).

This third edition cancels and replaces the second edition (ISO 13338:2017), which has been technically

revised with the following change:
The main changes compared to the previous edition are as follows:

— clarification in the document of the corrosiveness of gases and gases mixtures;

— clarification of the definition of FTSC codes for corrosiveness gases and gas mixtures in Clause 4;

— minor editorial changes in Table 1.

Any feedback or questions on this document should be directed to the user’s national standards body. A

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

method of the 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.

Gas cylinders — Gases and gas mixtures — Determination
of corrosiveness for the selection of cylinder valve outlet
1 Scope
This document provides:

— for pure gases and some liquids, a complete list indicating their corrosiveness;

— for gas mixtures, a calculation method, in the absence of experimental data, relating to the

corrosiveness of each of their components;

in order to determine the corrosiveness of gases and gas mixtures so that a suitable outlet connection

can be assigned to each of them.
