Brief: This video provides a brief case-style overview of the IEC 60335-2 Automatic Insulation Surface Scratch Resistance Test Apparatus in action. You will see how this advanced equipment performs precise scratch resistance tests on insulation surfaces for household appliances, demonstrating the testing methodology and key features that ensure compliance with international safety standards.
Related Product Features:
  • Evaluates scratch resistance of insulation surfaces on household appliances and similar equipment.
  • Meets requirements of multiple international standards including IEC 60335-1, IEC60950, and IEC 62368-1.
  • Uses a hardened steel pin with 40° conical tip and 0.25mm radius for precise scratching.
  • Features PLC + touch screen control system for accurate and programmable operation.
  • Stepper motor drive ensures precise movement control during testing cycles.
  • 90° auto-rotation test bench allows for both vertical and horizontal testing orientations.
  • Programmable parameters for scratch distance, cycles, and speed up to 25mm/s.
  • Applies controlled axial force of 10N±0.5N at 80°-85° angle to horizontal.
FAQs:
  • What standards does this insulation surface scratch resistance test apparatus comply with?
    The apparatus meets requirements of IEC 60335-1 clause 21.2, IEC60950:2013 clause 2.10.8.4, IEC 62368-1 clause 5.4.1.5.3, and multiple IEC 60335-2 series standards including -78, -95, -97, -103, and -40.
  • What types of samples can be tested with this equipment?
    It is designed for testing solid insulated parts that are touched, coated printed boards, or coated components of household and similar electrical appliances.
  • How is the scratching test performed and what parameters are controlled?
    The test uses a hardened steel pin with 40° conical tip at 80°-85° angle with 10N±0.5N axial force, creating parallel scratches at approximately 20mm/s speed covering about 25% of insulation length, with programmable distance, cycles, and speed parameters.
  • What control and drive systems does the apparatus use?
    It features a PLC + touch screen control system with stepper motor drive for precise movement control and a 90° auto-rotation test bench for comprehensive testing orientations.
