What anti-static standards are in reference to anti-static in various industries
Antistatic level can be divided into three levels: basic antistatic level, antistatic level, and conductive level. The anti-static standards of various industries are generally formulated in accordance with the two standards of IEC and ANSI/ESD.
1. Basic antistatic level: surface impedance value: 10 +9 ~ 10 +12 ohm.
2. Antistatic level (static dissipation): surface impedance: 10 +6 ~ 10 +9 ohm.
3. Static electricity level: surface impedance value: 10 +4 ~ 10 +6 ohm.
In high-precision rooms, such as wafer production lines, cutting rooms, ammunition warehouses, etc., where static electricity cannot be collected, static electricity must be discharged through static conductive grade materials to avoid danger.
For example, when performing an operation, doctors need to monitor various precision instrument indexes. If the computer or instrument is disturbed by static electricity and the readings are incorrect, it may cause the doctor to misjudge and cause the patient's danger. Another example is the accumulation of static electricity that may cause sparks. If it occurs in an ammunition depot, it may cause an explosion and cause disaster.
Anti-static level (static dissipative) offices, schools, libraries, museums, hospitals, wards, nursing centers, indoors in various public places, factory offices, manufacturing and processing plants.
