Brief: This video provides a detailed walkthrough of the Sandpaper Abrasion Test Apparatus, demonstrating how it evaluates automotive cable insulation resistance according to ISO 6722-1. You'll see the apparatus in action, learn about its precise angle and speed settings, and observe the testing process that ensures cable durability and compliance with international standards.
Related Product Features:
  • Tests automotive cable insulation abrasion resistance per ISO 6722-1 and ISO 19642-2 standards.
  • Features a selectable sandpaper tape speed ranging from 100mm/min to 1500mm/min for versatile testing.
  • Maintains a precise 29±2° angle between the sandpaper tape and the test sample for accurate results.
  • Accommodates test samples with a diameter up to 15mm and a length of 1 meter.
  • Uses standardized sandpaper tapes: 150J garnet or 180J Al2O3, with specific widths and conductive strip spacing.
  • Allows adjustable abrasion travel from 0 to 4000mm to suit various testing requirements.
  • Applies a controlled force of (0.63±0.05)N to the sample via a bracket, support rod, and pivoting arm.
  • Supports customizable weight options including 50g, 100g, 200g, 500g, and 1500g for different force applications.
Faqs:
  • What standards does this sandpaper abrasion test apparatus comply with?
    The apparatus is designed to comply with ISO 6722-1, ISO 19642-2, GB/T25085, QC/T730, JASO D608, JASO D611, SAE J1127, SAE J1128, and JIS C3406 standards, ensuring it meets international requirements for automotive cable testing.
  • What is the purpose of the sandpaper abrasion test for automotive cables?
    This test verifies the resistance of cable insulation to abrasion by sandpaper, measuring the length of sandpaper travel required to expose the conductor, which is critical for assessing cable durability and safety in automotive applications.
  • How is the test sample prepared and mounted in the apparatus?
    The test sample, with a diameter up to 15mm and length of 1m, is mounted taut without stretching between left and right clamps spaced 700mm apart, ensuring consistent and reliable test conditions.
  • What types of sandpaper tape are used, and how are they configured?
    The apparatus uses either 150J garnet sandpaper tape (5m length, 20mm width per ISO 6722-1) or 180J Al2O3 sandpaper tape (5m length, 10mm width with 75mm spacing per ISO 19642-2), both featuring conductive strips to detect conductor exposure.
