Anti-static clothing manufacturers to introduce to you the national standard of anti-static clothing.

First, the standard range:

This standard specifies the technical requirements, test methods, inspection rules, signs, etc. of anti-static clothing.

This standard applies to anti-static clothing that may cause electric shock, fire and explosion hazard.

The antistatic suits defined in this standard are not suitable for use against power supply voltages.

Standard number: GB 12014-2009

Chinese standard name: anti-static clothing

(Replacement standard number: GB 12014-1989 anti-static clothing)

Second, terms and definitions

The following terms and definitions apply to this standard.

Anti-static clothing

In order to prevent static electricity accumulation on the clothing, the anti-static fabric is used as the fabric, and the overalls are sewn according to the prescribed style and structure.

Anti-static fabric

In the case of weaving, a fabric spun from conductive fibers or a fabric formed by weaving conductive filaments may also be treated to prevent

Electrostatic properties of the fabric.

Conductive fiber

A fiber made of a conductive material or a static dissipative material of metal or organic in whole or in part.

Static dissipative material

A material having a surface resistivity greater than or equal to 1 x 10^5 ohms but less than 1 x 10^11 ohms.

Surface resistivity

A physical quantity that characterizes the electrical conductivity of an object's surface.

Point-to-point resistance

The ratio of the current voltage between the two electrodes on the surface of the material applied to the direct current flowing between the two points is applied at a given time.

Third, technical requirements:

1) Fabric:

- Appearance quality: The fabric should be free from damage, spots, dirt or other defects that affect the antistatic properties of the fabric.

- Detection parameters: The fabric is tested by point-to-point resistance method. The technical parameters are shown in the table below.

2) Clothing:

- Appearance quality: There should be no damage, spots, dirt and other defects that affect the wearing performance.

- Structure style: The structure of the garment should be safe and hygienic, which is conducive to the normal physiological requirements and health of the human body; the clothing should be easy to put on and take off and adapt to the physical activities during the operation; the clothing style should be simple and used. According to the use requirements.

- Sewing: The sewing lines of all parts are straight, tidy and firm. Up and down elastic, suitable, no jump needle, needle should have a back needle

- Detection parameters: Anti-static clothing is tested according to the method of charged charge. The technical parameters are shown in the table below.

3) Washing:

Antistatic clothing and fabrics must be cleaned as required prior to testing.
