|Publication Date:||1 April 2008|
|ICS Code (Relays):||29.120.70|
Scope and object
This section of IEC 255-22 is based on IEC 1000-4-2 and it refers to that standard where applicable.
This section specifies general requirements for electrostatic discharge tests of static measuring relays and protection equipment, with or without output contacts.
The object of the tests is to confirm that the equipment being tested will not maloperate when energized and subjected to an electrostatic discharge.
The requirements are applicable only to relays and protection equipment in new condition.
The tests specified in this standard are type tests.
The object of this standard is to state:
a) definition of terms used;
b) test severity classes;
c) test conditions;
d) test procedures;
e) criteria for acceptance.
