Overview

EN 60512-2-3:2002 (IEC 60512-2-3:2002) defines a standardised test method - Test 2c: Contact resistance variation - for measuring how the contact resistance of electromechanical components (primarily connectors for electronic equipment) changes under specified dynamic conditions. Published by CLC/CENELEC and based on IEC technical committee 48 work, this part of IEC 60512 is intended to be referenced in detail specifications when contact resistance stability is a requirement.

Key topics and technical requirements

  • Scope: Applies to electromechanical components within IEC TC 48 scope; used only when Test 2a (contact resistance measured by the millivolt-level method) is applicable.
  • Test objective: Determine variation of contact resistance under dynamic conditions specified by the detail specification.
  • Measurement method:
    • Measurements are carried out in accordance with IEC 60512-2-1 (Test 2a) using a d.c. test current not exceeding 50 mA.
    • Apparatus must display voltage drop between designated points and be adapted for required bandwidth and sensitivity (e.g., oscilloscope or recorder).
    • Guidance example: d.c. to 20 kHz bandwidth and 50 μV sensitivity corresponds to about 1 mΩ resolution, suitable for most cases.
  • Dynamic testing: Contact resistance variation is assessed during the dynamic event(s) specified (e.g., mechanical movement, mating/unmating cycles) and over the period given in the detail specification.
  • Pass/fail: The permissible limit of variation is defined by the relevant detail specification; the standard requires the variation not exceed that value.
  • Details to be specified: Mounting/wiring method, variation limits, associated dynamic test severity, which contacts to measure, measuring apparatus sensitivity/bandwidth, and any deviations from the standard method.

Practical applications

  • Qualification and validation of connectors and electromechanical contacts used in:
    • Industrial control systems
    • Automotive and transport electronics
    • Telecommunications and data centers
    • Consumer and medical electronic equipment
  • Ensures reliability of electrical continuity where transient or mechanical conditions can cause contact resistance fluctuations that affect performance or safety.
  • Useful for supplier quality control, product development, compliance testing, and acceptance criteria definition.

Who uses this standard

  • Connector manufacturers and component designers
  • Test laboratories and compliance engineers
  • Procurement and quality assurance teams specifying acceptance criteria
  • R&D engineers validating connector performance under dynamic conditions
