introduction
In addition to the electrostatic safety hazards and the damage and interference to sensitive electronic equipment and systems that have been included in other standards, the static electricity of clothing will also
Cause problems such as adhesion, uncomfortable electric shock, adsorption of dust and other pollutants in the air.
In some fast-developing industries related to precision technology, biotechnology, food, hygiene, etc., clothing is required to block air dust and pollution.
At the same time, the wearer usually hopes that the clothing will not stick to the skin or produce uncomfortable electric shocks.
Many national and international standards, including ISO and IEC, have standards for electrostatic performance evaluation, which are used to guide clothing design.
To avoid problems caused by static electricity. However, the relationship between the measured electrostatic performance and the end-use performance is more complicated and may require
Use different methods for testing according to the actual situation of the application.
This document is one of the testing methods for the electrostatic properties of textiles. This document does not give clear performance requirements, only in the informative Appendix A
The reference for the evaluation of the results is given in the performance evaluation table. The performance evaluation table is based on the prevention of adhesion, electrostatic discharge discomfort and particulate pollutants in the industry.
Adsorption and other related experiences are set for reference only. It is recommended that users of this document check their applicability according to their own application conditions.

are accumulated on the sample.
3.2
Static half period
The time that is required for the electrostatic voltage on the sample to decay to
half of the original value.

6 Atmospheric conditions for humidifying and testing
The environmental conditions of the atmosphere for humidifying and testing are:
the temperature is (20 ± 2) °C; the relative humidity is (35 ± 5) %; the ambient
wind speed shall be below 0.1 m/s.
7 Sample preparation
7.1 Pretreatment
7.1.1 If necessary, wash in accordance with the 7A procedure in GB/T 8629-
2001; the parties concerned can choose to wash 5, 10, 30, 50 times through
consultation; for multiple washings, the time can be accumulated for continuous
washing. Or wash according to the method and frequency approved by the
relevant parties.
Note: When the time is accumulated, the time of washing, flushing 1, flushing
2, and flushing 3 in the 7A procedure shall be accumulated respectively.
7.1.2 Pre-bake the sample or the washed sample at 50 °C for a certain period
of time.
7.1.3 Place the pre-baked sample in the environment of Chapter 6 for more
than 24 hours; the sample shall not be stained.
7.2 Sample
7.2.1 Take 3 groups of samples at random; the size of each sample is 4.5 cm ×
4.5 cm or a suitable size. The number of samples in each group depends on
the number of sample tables in the instrument. The sample shall be
representative and free of defects that would affect the test results.
7.2.2 Slivers, filaments and yarns shall be evenly and densely wound on a flat
plate of the same size as the sample of 7.2.1.
7.2.3 During operation, avoid touching the sample with hands or other objects
that may stain the sample.
8 Test procedure
8.1 Calibrate the instrument before the test.
8.2 Discharge the surface of the sample.
8.3 Clamp the sample in the test clamp so that the pin electrode and the upper
surface of the sample are separated by (20 ± 1) mm, and the sensing electrode
and the upper surface of the sample are separated by (15 ± 1) mm.
Note: When changing the sample, the distance between the pin electrode and
the sensing electrode and the upper surface of the sample shall be re-
adjusted, so as to meet the specified requirements.
8.4 Drive the test bench; apply a high voltage of 10 kV to the pin electrode after
the rotation is stable.
8.5 After applying pressure for 30 seconds, disconnect the high voltage; the test
bench continues to rotate, until the electrostatic voltage decays below 1/2; then,
stop the test; record the sample electrostatic voltage (V) at the moment of high
voltage disconnection and the time required to decay to 1/2 [i.e., half period (s)].
Note: When the half period is greater than 180 s, stop the test, and record the
residual electrostatic voltage value at the decay time of 180 s, or record
the residual electrostatic voltage value at 60 s, 120 s or other decay times
if necessary.
9 Test results
9.1 Perform two tests on the same sample (group); calculate the average value
as the measured value of the sample (group).
9.2 Perform the same test on 3 samples (groups); calculate the average value
as the measured value of the sample. Round the final result of electrostatic
voltage to 1 V, and of half period to 0.1 s.
10 Technical requirements and evaluation of the half
period
The technical requirements of the half period are shown in Table 1. For non-
