What Is IEC 60099?

IEC 60099 is a multi-part international standard for surge arresters – devices that protect electrical equipment from overvoltages (e.g., lightning strikes, switching surges).

The standard is officially titled:
IEC 60099 – Surge arresters

It consists of several parts:

| Part | Title | |------|-------| | IEC 60099-1 | Non-linear resistor type gapped arresters for a.c. systems | | IEC 60099-4 | Metal-oxide surge arresters without gaps (most common today) | | IEC 60099-5 | Selection and application recommendations | | IEC 60099-6 | Surge arresters containing both series and parallel gapped structures | | IEC 60099-8 | Metal-oxide surge arresters with external series gap (EGLA) |

Note: You wrote “iec 600995” – likely a typo for IEC 60099-5 (Part 5) or simply IEC 60099.

Why it matters right now

• Reliability in critical infrastructure: Hospitals, data centers and emergency communications depend on predictable battery behavior during outages. Compliance reduces failure risk.
• Procurement clarity: Specifying IEC 60095–compliant batteries avoids vendor ambiguity and hidden tradeoffs (e.g., capacity rated at unrealistic conditions).
• Safety and liability: Using standardized, tested products lowers the chance of hazardous incidents and simplifies regulatory compliance.
• Sustainability lifecycle: Standards encourage testing protocols that reveal degradation modes, informing recycling and replacement policies.
