Introduction
Core changes in the standard revision
| Change dimensions | 2001 version | 2020 version | Technical significance |
|---|---|---|---|
| Anti-static performance classification | No distinction between long-term and short-term effects | Added boiling water for 8 hours test | Ensure long-term stability |
| PVC veneer size deviation | Uniform ±0.3mm | Controlled by thickness classification (0.1-0.2mm) | Adapt to the accuracy requirements of different application scenarios |
| Test environment level | Not clearly specified | Added a 4-level humidity control system | Improve comparability of test results |
Analysis of key performance indicators
Resistance value classification requirements
Conductive type: 1.0×10⁴~1.0×10⁶Ω | Static dissipative type: 1.0×10⁶~1.0×10⁹Ω
Test voltage is dynamically adjusted according to the resistance range:
- ≤10⁵Ω uses 10V voltage
- ＞10⁵Ω uses 100V voltage
Material property comparison
| Characteristics | PVC anti-static laminate | HPL anti-static laminate |
|---|---|---|
| Abrasion resistance (1000 turns) | ≤0.02g/cm² | According to GB/T17657 |
| Heating dimensional change rate | ≤0.25% | ≤0.30% |
| Environmental protection requirements | In line with GB18586 | In line with GB18580 |
Implementation suggestions
Selection decision tree
- Determine the humidity level of the operating environment (it is recommended to give priority to environmental level 3)
- Choose conductive or dissipative type according to the requirements of electrostatic protection
- For long-term use, long-lasting products that have passed the 8-hour boiling water test must be selected
- High wear resistance requirements give priority to HPL anti-static veneer
Acceptance points
- Roll length deviation: +100mm (need to be measured with a steel tape measure under tension-free state)
- Block material straightness: ≤0.8mm/m (use a grade 0 square ruler with a feeler gauge for detection)
- Pre-treatment for 48 hours at 23±2℃, 50±5%RH before testing
