《GB/T 12703.1-2021纺织品 静电性能试验方法 第1部分：电晕充电法》由TC209（全国纺织品标准化技术委员会）归口，TC209SC1（全国纺织品标准化技术委员会基础标准分会）执行，主管部门为中国纺织工业联合会。
Introduction
Key points of core changes in the standard
| Technical parameters | 2008 version | 2021 version | Impact of changes |
|---|---|---|---|
| Half-life termination condition | 180s | 120s | Improve test efficiency |
| Relative humidity control | Tolerance is not specified | (40±4)% | Improve data comparability |
| Number of samples | Not specified | 5 pieces | Ensure statistical validity |
Key requirements for instrument configuration
The test system must include:
- Discharge electrode: needle tip curvature radius ≤0.5mm, applied (-10±1)kV voltage
- Sensing electrode: diameter (28±0.5)mm flat plate, response time <4ms
- Rotating platform: diameter (200±4)mm, rotation speed ≥1000r/min
Actual application case
A medical protective clothing manufacturer used this standard to test and found that: The half-life of the fabric treated with class=instrument>conductive fiber is ≤2s, while that of the untreated fabric is >120s, which proves that conductive fiber can significantly improve the antistatic performance.
Technology Evolution Analysis
This standard is modified to adopt ISO18080-1:2015. The main technical differences include:
- The detergent type is clarified as GB/T8629 standard detergent 3
- The discharge needle distance tolerance is adjusted from ISO's ±0.5mm to ±1mm
- The test result rounding rule is added (two significant figures)
Implementation suggestions
Laboratories should pay attention to:
- Strictly control the environmental conditions at (20±2)℃, (40±4)%RH
- Use static eliminator to treat the sample before each test
- Regularly calibrate the electrode distance (20±1mm between the discharge needle and the sample surface)
