Antistatic level, can be divided into basic antistatic level, antistatic level, electrostatic conduction level three levels. Anti-static standards in various industries are generally developed according to the IEC and ANSI\/ESD two standards.
1, basic antistatic level: surface electric resistance value (surface electric resistance) :10 9 ~ 10 12 ohm.
2, antistatic level (electrostatic dissipation) : surface electric resistance value (surface electric resistance) :10 6 ~ 10 9 ohm.
3, electrostatic conduction level: surface electric resistance value :10 4 ~ 10 6 ohm.
