ISO 13585:2021

Overview - What ISO 13585:2021 covers

ISO 13585:2021 specifies requirements for the qualification testing of brazers and brazing operators working with metallic materials. It defines how to assess and document the competence of personnel who directly influence the quality of brazed joints, and it gives general provisions on brazing quality (see Annex A). The standard applies to a broad set of brazing processes (local and global heating) and establishes the essential variables, test methods and certification requirements needed to demonstrate repeatable, production-level brazing competence.

Key technical topics and requirements

• Scope of processes covered - Includes infrared, flame/torch, laser, electron beam, induction, resistance, diffusion, furnace, vacuum, dip-bath, salt-bath, flux bath, immersion, and arc weld brazing (ISO 857‑2 / ISO 4063 references).
• Personnel categories - Distinguishes between a brazer (manual hand-held heating) and a brazing operator (controls/sets parameters for mechanized or automatic brazing).
• Essential variables and ranges of qualification - Defines variables that determine qualification scope, for example:
  • Brazing process number
  • Product type (pipe or plate), joint type (butt, lap, T‑joint)
  • Parent material group(s) (see Annex E material grouping)
  • Filler metal classification and application (face-fed or pre-placed)
  • Dimensions (thickness, diameter, overlap) and filler‑metal flow direction
  • Type of equipment (for brazing operators)
• Examination and testing methods - Requires visual inspection, non‑destructive and destructive testing as appropriate (Clauses 6–8) and assessment of test pieces and specimens.
• Certification and validity - Provides templates for qualification certificates (Annexes B and C) and rules for re-testing, prolongation and a typical validity period (revised to five years).

Practical applications - Who uses this standard

• Manufacturing quality and welding engineers implementing brazing quality programs.
• Training and certification bodies issuing brazer and brazing operator qualifications.
• Production supervisors and procurement teams specifying competence requirements in contracts.
• Fabrication shops, heat‑treatment and joining facilities that require documented operator qualification for metallic brazed assemblies.
• Inspectors and examining bodies verifying compliance with brazing procedure specifications (BPS / pBPS).
