Complete Testing Methods for Alcohol Lint-Free Wipes:

1. Basic Physical Performance Tests

  • Fiber Shedding Test:

    • Method: IEST-RP-CC004.3 standard, using particle counter for ≥0.5μm particles

    • Pass Criteria: <100 particles/m³ (Class 100)

  • Liquid Absorption Rate:

    • Method: ASTM E2315, measure time for 1μL alcohol absorption

    • Pass Criteria: <2 seconds

2. Chemical Safety Tests

✅ Alcohol Residue:

  • GC-MS test, limit <0.01ppm
    ✅ Heavy Metals:

  • ICP-OES test for Pb/Cd/Hg, compliant with RoHS 2.0

3. Functional Verification

  • Cleaning Efficiency:

    • Apply 0.5μm silicone oil on 304 stainless steel, wipe and measure residue (<0.1μg/cm²)

  • Static Control:

    • Surface resistance tester (10⁶-10⁹Ω acceptable)

4. Industry-Specific Standards

Industry Key Tests Standard
Semiconductor ESD Performance ANSI/ESD S20.20
Medical Sterility Assurance (SAL) ISO 11737-1
Optics Silicone Residue ISO 9022-22

5. On-Site Quick Tests

  • UV Contamination Check: 365nm UV lamp for fluorescent contaminants

  • Tape Test: Press adhesive tape to surface to check fiber shedding
