General Information

Overview
EN ISO 2503:2009/A1:2015 is the CEN-adopted amendment to ISO 2503:2009 covering gas welding equipment - specifically pressure regulators and pressure regulators with flow‑metering devices for gas cylinders used in welding, cutting and allied processes up to 300 bar (30 MPa). Amendment A1 (approved 2015) updates marking and identification requirements to align with the revised gas letter code system introduced in ISO 10225. The amendment is endorsed by CEN without modification and is intended for manufacturers, test houses and users of gas welding regulators across Europe and internationally.
Key Topics and Requirements
- Scope: Regulators and regulators with integrated flow‑metering for gas cylinders up to 300 bar (30 MPa).
- Marking and identification: When the full gas name or chemical symbol cannot be applied, the gas letter codes from ISO 10225 must be used for equipment marking (modification to Clause 7.1).
- Normative references: Amendment adds ISO 10225 to the list of referenced standards (modification to Clause 2).
- Document edits: The amendment replaces the previous marking bullet, and removes Table 5 from the base standard as part of the update.
- Safety and conformity: Ensures consistent identification and traceability of regulators used in welding and allied processes, helping users meet regulatory and safety management requirements.
Applications and Who Uses It
This standard is practical for:
- Manufacturers and designers of pressure regulators and flow‑metering devices - to ensure product marking and documentation comply with current international conventions.
- Procurement and quality managers - to specify compliant equipment for welding and cutting operations.
- Testing and certification bodies - to assess marking, safety and conformity against EN ISO 2503:2009/A1:2015.
- Safety officers and maintenance teams - for correct identification of gas service and safe replacement or servicing of regulators.
- Welding and fabrication workshops - to select appropriate, clearly marked regulators for oxy‑fuel and other gas processes.
Practical uses include product design verification, factory acceptance checks, procurement specifications, and workplace safety audits where correct gas identification and regulator compatibility are critical.
