Overview
ISO 10225:2013 specifies a standardized gas letter code for marking equipment used in gas welding, cutting and allied processes when the full gas name or chemical symbol cannot be used. Published by ISO/TC 44 (Welding and allied processes), this concise standard ensures consistent, unambiguous identification of gases on torches, hoses, fittings and related gas-welding equipment to support safety, compatibility and traceability.
Key Topics and Requirements
- Scope: Applies to marking of gas welding, cutting and allied equipment when full gas names or chemical symbols are impractical.
- Primary requirement: Use the letter codes in Table 1 of ISO 10225:2013 for marking equipment instead of full names.
- Mandatory codes (selected from the standard):
- Oxygen - O
- Air - D
- Nitrogen / inert gases - N
- Carbon dioxide - B
- Acetylene - A
- Hydrogen - H
- MPS - Y
- Natural gas / methane - M
- Propane / butane / LPG - P
- Ethylene - E
- Propylene - L
- Coal gas / town gas - C
- Other combustible gases or mixtures - F
- Special note on code F: If F is used for combustible gases or multi-gas compatibility, the manufacturer must supply instructions that specify the full gas names and detailed compatibility information.
- Traceability and safety: The code system reduces confusion in environments where space on equipment is limited or multilingual markings are required.
Applications
ISO 10225:2013 is practical for:
- Marking torches, torches heads, mixers, hoses, regulators and fittings used in gas welding and cutting.
- Manufacturers and OEMs creating compact labels where full names or chemical symbols won’t fit.
- Safety documentation and labeling programs in workshops, fabrication shops, and industrial plants.
- Procurement and inventory systems to standardize equipment identifiers across suppliers and international operations.
Who should use this standard
- Equipment manufacturers and designers of gas welding/cutting tools
- Safety officers, workshop managers and maintenance teams
- Suppliers, distributors and inspectors handling gas welding equipment
- Standards committees and regulatory bodies coordinating marking and safety guidance

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.

L’ISO (Organisation internationale de normalisation) est une fédération mondiale d’organismes
nationaux de normalisation (comités membres de l’ISO). L’élaboration des Normes internationales est
en général confiée aux comités techniques de l’ISO. Chaque comité membre intéressé par une étude
a le droit de faire partie du comité technique créé à cet effet. Les organisations internationales,
gouvernementales et non gouvernementales, en liaison avec l’ISO participent également aux travaux.
L’ISO collabore étroitement avec la Commission électrotechnique internationale (CEI) en ce qui concerne
la normalisation électrotechnique.
Les procédures utilisées pour élaborer le présent document et celles destinées à sa mise à jour sont
