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

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
