This Standard specifies the technical requirements, test methods, inspection
rules, identification, etc. of static protective clothing.
This Standard applies to static protective clothing worn in places that may
cause electric shock, fire and explosion hazards due to static electricity.
This Standard does not apply to non-woven static protective clothing and static
protective clothing for power supply voltage protection.

3 Terms and definitions
For the purpose of this document, the following terms and definitions apply.
3.1
static protective clothing
Work clothing that are made of static protective fabric and according to the
specified style and structure to reduce the accumulation of static electricity on
the clothing.
3.2
static protective fabric
Fabrics that are woven of yarn mixed with conductive fibres or embedded
conductive filaments when weaving, or fabrics that are made of treated
electrostatic dissipative materials.
3.3
electrostatic dissipative material
Materials of which the surface resistivity is greater than or equal to 1 × 105 Ω/□,
but less than 1 × 1011 Ω/□.
3.4
conductive fibre
Fibres that are all or partially made of conductive materials or electrostatic
dissipative materials.
3.5
surface resistivity
Ratio of the potential gradient that is parallel to the direction of the current
passing through the surface of the material TO the current per unit width of the
surface, that is, the DC resistance between two opposite sides of a square
material per unit area.
NOTE. Unit. Ω/□.
4 Technical requirements
4.1 Fabric
4.1.1 Appearance quality
Test according to the method specified in 5.1, the fabric shall be free of damage,
spots, dirt or other defects that affect the performance of the fabric.
4.1.2 Physical and chemical properties of woven fabrics
The physical and chemical properties of woven fabrics shall meet the
requirements of Table 1.For clothing with lining, the formaldehyde content, pH
value and decomposable carcinogenic aromatic amine dyes of the lining shall
meet the requirements of Table 1.
4.1.3 Physical and chemical properties of knitted fabrics
The physical and chemical properties of knitted fabrics shall meet the
requirements of Table 2.For clothing with lining, the formaldehyde content, pH
value and decomposable carcinogenic aromatic amine dyes of the lining shall
meet the requirements of Table 2.
4.2 Clothing
4.2.1 Clothing fabrics
The fabrics of finished clothing shall meet the technical requirements of 4.1.
4.2.2 Structure and style
The clothing structure shall be easy to put on and take off and adapt to physical
activities during work. If the clothing itself has a multilayer structure, it shall be
able to ensure that the outermost material always covers the inner clothing
when worn.
4.2.3 Size and specifications
The size and specifications of static protective clothing for men are selected
according to the requirements of GB/T 1335.1, and the size and specifications
of static protective clothing for women are selected according to the
requirements of GB/T 1335.2.
4.2.8 Antistatic performance of clothing
4.2.8.1 Where stripe-like or grid-like conductive fibers or conductive filaments
are used to achieve antistatic performance, the spacing of conductive materials
shall not be greater than 10 mm.
4.2.8.2 Test according to the method specified in Annex B, the charged electric
charge shall not be greater than 0.60 μC/set.
5 Test methods
5.1 SPREAD the fabric or clothing flat on the table; OBSERVE at a distance of
1.5 m from the product under good lighting conditions. Broken warp, broken
weft, damage and stains are not allowed.
5.2 SELECT samples from different parts of the fabric and clothing lining, and
TEST the formaldehyde content according to the method specified in GB/T
2912.1.
5.5 The smell is tested according to the method specified in GB 18401.
5.6 The dimensional change rate and relaxed dimensional change rate of the
fabric are carried out according to the provisions of GB/T 8628 and GB/T 8630.
Use the 4N procedures in GB/T 8629 to wash; woven fabrics are dried by
hanging and drying, and knitted fabrics are dried by flat drying.
5.7 SELECT 10 samples from different parts of the fabric or clothing, and TEST
the air permeability according to the method specified in GB/T 5453.
5.8 The color fastness to washing of fabrics is tested according to the method
A (1) specified in Table 2 of GB/T 3921-2008.
5.16 The tester wears clothing of suitable size and performs the following
actions.
5.17 The seam strength of finished clothing adopts different test methods
according to the different fabrics used in the clothing. The clothing made of
woven fabrics is tested according to the method specified in GB/T 3923.1.CUT
five samples with the seam in the center from the part with weak seam, and the
direction of the seam is at a 90° angle to the direction of the force.
6 Inspection rules
6.1 Factory-exit inspection
The manufacturer shall carry out the factory-exit inspection on the static
protective clothing batch by batch according to the production batch. See Table
5 and Table 6 for the test items, test sample size, non-conformity classification
