Foreword
2006 "Protective clothing - Electrostatic properties - Part 1.. surface resistivity test method" to adopt the European standard EN1149-1 This standard is identical
(In English).
For ease of use, this standard made the following editorial changes.
a) the standard name to "clothing anti-static properties of the surface resistivity test method";
b) "The European Standard" be replaced by "this standard";
c) use a decimal point instead of a decimal comma ",". ",";
d) with the "ln" instead of "loge";
e) Remove European standard preface, introduction;
f) Remove European standard informative appendix;
g) increase information appendix.
NA appendix of this standard is an informative annex.
The standard proposed by China Textile Industry Association.
This standard by the National Standardization Technical Committee apparel (SAC/TC219) centralized.
Drafting of this standard. Wenzhou City of Quality and Technical Supervision and Inspection Institute, Shanghai Institute of clothing.
The main drafters of this standard. yellow win, Zhang Dawei, Lin Ouwen, Nieya Yuan, Xu Jian, Wang Hongming.
This standard was first published.
Clothing anti-static properties Surface Resistivity Test Method
1 Scope
This standard specifies the test methods to eliminate static electricity spark anti-static protective clothing (or gloves) material used.
This standard does not apply to the anti-material supply voltage protective clothing or gloves used.

3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
By specific surface electrodes are placed to measure the resistance in ohms (Ω).
3.2
Along the surface of the material on opposite sides of a square between the resistance in ohms (Ω).
Note. The surface resistivity of the electrode size has nothing to do, by the surface resistance measured with a suitable factor calculated by multiplying.
Test Method 4
4.1 Principle
The sample is placed on an insulating chassis, and then placing one electrode arrangement on the specimen. The direct current through the electrode device, and then measuring the fabric
resistance.
4.2 Device
4.2.1 Electrode
By a cylindrical electrode and ring electrodes coaxial components. A stainless steel electrode as shown in Fig. 4.4.2 When in accordance with the
When the method of measuring internal and external electrode insulation resistance should not be less than 1014Ω.
4.2.2 flat chassis
Flat chassis by a surface resistivity of not less than 1014Ω (see 4.4.2), the thickness of 1mm to 10mm between the insulating material composition, and should
Is greater than the maximum size of the electrode. The chassis used in the measurement of the sample-receiving samples, according to the order placed on the surface of the ground conductor, such as metal plate.
4.2.3 Resistance Meters
Measuring range resistance meter. 105Ω ~ 1014Ω.
The maximum permissible error. ≤1012Ω when, ± 5%;
