Standards for common anti-static products
First, the test of the wrist strap
1. Test standard: ANSI/ESD S1.1
2, the type of test: Evaluation (laboratory testing);; Acceptanceteating; Functional testing
3. Test and evaluation indicators: connection line resistance, internal and external resistance of wristband, mechanical strength, system resistance
Second, the test of anti-static clothing
1. Test standard: ANSI/ESD2.1, IEC61340-5-1-ANNES-A
2, test and evaluation indicators: sleeve to sleeve resistance, point-to-point resistance, dissipation speed (IEC61340-5-1-ASSEX-A)
3, test environment: laboratory testing at low humidity 23 ± 3 ° C 12 ± 3% RH ≥ 48H placed and MODERATE HUNIDITY 23 ° C ± 3 ° C, 50 ± 5% RH ≥ 48H placed
4, indicator requirements: 1 * 10 5 power to 1 * 10 11 power
Third, the test of the work surface
1. Test standard: ESD S4.1 resistance measurement, ESDSTM 4.2 charge dissipation characteristic
s
2, instrument requirements: the same surface resistance measurement requirements
3, test environment: laboratory testing at low humidity 23 ± 1 ° C 12 ± 3% RH ≥ 48H placed and MODERATE HUNIDITY 23 ° C ± 1 ° C, 50 ± 5% RH ≥ 48H placed
4. Sample: S4.1: 25.4*61CM, with two grounding points on each sample; S4.2: 61*61CM
