1, Antistatic Performance
The domestic anti-static overalls standard GB12014 - 2009 of the antistatic performance is the main testing point to point resistance, that is, in a given period of time, applying anti DC voltage and flow through the static fabric surface between the two electrodes of the two the DC current ratio. The EU's anti - static work clothing Standard Test Method BSEN1149-1 is for most properties of electrostatic dissipation behavior of surface resistance based on the determined resistance, it is a short distance. More test items on the antistatic property of the fabric of the EU standards, in addition to the short distance of the resistance and loop resistance tests and so on.
2, The Test Environment Conditions
Environmental temperature and humidity on the antistatic clothing anti electrostatic performance of great influence. So the test environment anti-static clothing have strict rules, such as the European standard of environmental requirements for temperature (23 + 1) C, relative humidity (25 + 5)%, demands on the environment standard for temperature (23 + 3) C, relative humidity (50 + 5)% in 2001, Japan revised standards for temperature (25 + 5) C, relative humidity (45 + 5)%[2]. National standards for ambient temperature differences is not big, but the difference of environmental humidity America and Europe standard reached about 30%. Test the temperature of our country in the new regulations for the (20 + 5) C, relative humidity (35 + 5)%.
