Overview

EN ISO 9312:2013 (ISO 9312:2013) specifies requirements for insulated pins used to pin parts in the secondary circuit of resistance welding equipment (for example in electrode back-ups) or in other live equipment where parts must be electrically insulated from each other. This European adoption supersedes earlier editions and aligns the design, material and dimensional requirements for commonly used insulated pins.

Key topics and requirements

  • Scope: Pins intended to isolate live parts in the secondary circuit of resistance welding equipment and similar live apparatus.
  • Dimensions: Standard diameters covered include 6 mm, 8 mm, 10 mm and 12 mm, with corresponding overall lengths 30, 40, 50 and 60 mm respectively and specified insulating detail dimensions (see Table 1 of the standard).
  • Designation: Standardized naming format, e.g. “Insulated pin ISO 9312:-, 8” for an 8 mm pin.
  • Material: Insulating body made from hard fabric, coarse weave phenolic laminated material complying with IEC 60893-3-4 classifications (PF CC 201 or PF CC 202).
  • Finish and tolerances: Dimensional tolerances without individual indications are medium (ISO 2768-1, designation m). Surface texture reference is ISO 1302 where applicable.
  • Application guidance: Typical application examples are referenced in ISO 5827 (electrode back-ups and clamps).
  • Normative references: ISO 2768-1, ISO 5827 and IEC 60893-3-4 are essential for correct implementation.

Practical applications and users

EN ISO 9312:2013 is directly relevant to:

  • Welding-equipment manufacturers specifying or sourcing insulated pins for electrode back-ups and secondary-circuit assemblies.
  • Maintenance and service engineers replacing insulated pins in resistance welding machines.
  • Purchasing and quality teams ensuring supplied parts meet standard dimensions, material and tolerance requirements.
  • Designers and safety engineers who need to ensure electrical isolation in live welding equipment and to specify compatible components.

Benefits of using the standard:

  • Ensures interchangeability and safety of insulated pins across equipment vendors.
  • Simplifies procurement with a clear designation and material requirement.
  • Helps maintain regulatory compliance and reduce risk of electrical shorting in welding secondary circuits.

Related standards

  • ISO 5827 - Spot welding: electrode back-ups and clamps (typical application context).
  • ISO 2768-1 - General tolerances for linear and angular dimensions.
  • IEC 60893-3-4 - Specifications for phenolic rigid laminated insulating materials.
  • ISO 1302 - Surface texture indication (referenced for finish).
