Overview
EN ISO 9013:2017/A1:2024 is Amendment 1 to ISO 9013:2017 - the international standard for thermal cutting that defines the classification of thermal cuts and the associated geometrical product specification (GPS) and quality tolerances. Published as a CEN-endorsed amendment in 2024, it updates normative references and aligns surface texture requirements with the newer ISO GPS series for profile surface texture.
Key factual points:
- Amendment modifies EN ISO 9013:2017 without other technical changes.
- Approved by CEN on 16 April 2024 and to be implemented by CEN members (national adoption deadline March 2025).
- Prepared by ISO/TC 44 (Welding and allied processes) in collaboration with CEN/TC 121.
Key topics and technical changes
This amendment focuses on updating references related to surface texture and indication within the GPS framework:
- Removes the reference to withdrawn ISO 1302:2002.
- Replaces references to withdrawn ISO 4288 with ISO 21920-3: Geometrical product specifications (GPS) - Surface texture: Profile - Part 3: Specification operators.
- Updates clause cross-references: clauses 6.2.2.3, 6.2.3 and 10.2.1 now reference ISO 21920-3 or ISO 21920-1 as applicable.
- Adds ISO 21920-1 (Surface texture: Profile - Part 1: Indication of surface texture) to the bibliography.
What this means practically:
- Surface texture measurement terminology and indication methods in ISO 9013 are now consistent with the latest GPS profile standards (ISO 21920 series).
- Quality tolerances and specification operators for thermal cutting will reference current GPS methods rather than withdrawn standards.
Applications and users
EN ISO 9013 (with Amendment 1) is used by professionals and organizations involved in thermal cutting and downstream processes where cut geometry and surface quality matter:
- Welding and cutting shops, plate and structural fabricators
- Welding engineers, quality control and inspection personnel
- Designers and procurement specialists specifying cut tolerances and surface requirements
- Equipment manufacturers for oxy-fuel, plasma, laser and other thermal cutting systems
- Certification bodies and standards committees implementing GPS-based surface specification
Practical uses:
- Specifying acceptable cut classes and tolerances on drawing notes and contracts
- Defining surface texture and profile acceptance criteria for post-cut fabrication or welding
- Harmonizing inspection procedures with up-to-date GPS standards
