Here are the three most critical takeaways to remember about the IEC 255-22-2 standard:

1. Purpose: To ensure electrical protection devices don’t fail when zapped by static electricity, which is commonly generated by the human body.
2. Primary Target: It applies specifically to new static measuring relays and protection equipment.
3. Core Principle: It standardizes test methods (Contact and Air discharge) and severity levels to make testing reliable and repeatable across different products and manufacturers.
