Test Method and Standard of Antistatic Performance
The antistatic performance can be checked by testing surface resistance and decay time of film.
Test Method Standard:
ASTM (American Society for Testing Materials)
ASTM D257 Standard Test Method for DC Resistance of Conductance of Insulating Materials
ANSI (American National Standards Institute)/ESD(Electro-Static Discharge)
ANSI/ESD STM4.2 Test Method for Protection of Electrostatic Discharge Susceptible Items - ESD Protective Worksurfaces Charge Dissipation Characteristics
Test instrument：
