Measure includes but are not limited to wear the measures such as anti-electrostatic clothing, anti-static shoes, band ESD-preventive wrist strap, but these measures are for quiet
Electricity protection actual effect on earth how, be required for various evaluation and test means to go to be detected, evaluate and test.
For example, for anti-electrostatic clothing, its sheet resistance and Abrasive voltage are usually artificially tested, is such as less than a fixed limit
System, then it is assumed that it is electrostatic protection safety, but this evaluation and test mode is problematic：
Just as it is well known that the height of two material Abrasive voltages and electricity mutually rubs with personnel's movement range and two
Wiping the order of the electrostatic between material has relation, and when evaluating result also only can be shown that test and appraisal anti-electrostatic clothing state,
So simple laboratory evaluating method can not truly reflect the actual electrostatic protection feelings that antistatic clothing is mounted in actual application environment
Condition, once the result of laboratory test and appraisal and the situation of practical application scene differ greatly, is individually carried out quiet using anti-electrostatic clothing
Electricity protection may cause the accident, and there are certain hidden danger.
And it is grounded bleed-off system when anti-electrostatic clothing is combined with other electrostatic protection measures, such as with wrist static electrification
With the use of when, and need to coordinate wrist band detector etc. to aid in detection means to confirm electrostatic, and the meeting such as wrist band detector
Take the limited space of each station.
