As of 2026, IEC 60099-5 Edition 3.0 (2018) remains the current standard, offering guidelines for selecting and applying surge arresters in three-phase systems exceeding 1 kV. This 2018 version, which replaced the 2013 edition, is active and directly aligned with the revised classification system in IEC 60099-4:2014. Key technical updates include:

Classification Shift: Replaced "line discharge class" with a focus on thermal energy ratings ( Qthcap Q sub t h end-sub Wthcap W sub t h end-sub ) and repetitive charge transfer ratings ( Qrscap Q sub r s end-sub ).

Updated Guidance: Enhanced formulas for calculating charge and new annexes covering class comparisons (Annex H), energy estimation (Annex I), and SiC arrester replacement (Annex J).

The Correct Standards: IEC 61000-4-30 and IEC 62586

Q1: Is there an official IEC 600995 standard?

A: No. It is a common typo. Use IEC 61000-4-30 or IEC 62586.

2. Scope and Purpose

This standard serves as a technical guide rather than a testing specification. While other parts of the series (like Part 4) define how to test an arrester, this part explains how to use it.

It provides recommendations for the selection and application of surge arresters for the protection of AC electrical systems against overvoltages (typically caused by lightning or switching operations).

Q3: Which update is the most current for power quality?

A: As of 2025, IEC 61000-4-30 Edition 3.1 (2021) + Corrigendum 1 (2022). Check the IEC webstore for any newer amendments.

4. Obtaining the PDF

Obtaining official standards requires adherence to copyright laws. Here is how to legally access the document:

1. IEC Webstore (Official Source):

   • Go to webstore.iec.ch.
   • Search for "IEC 60099-6" (for the application guide) or "IEC 60099-4" (for the test standard).
   • You can purchase the PDF here. This guarantees you have the latest, watermarked, and authentic version.

2. National Committee Mirror Sites:

   • IEC standards are often adopted by national bodies.
   • USA: ANSI/IEEE (IEEE Std C62.22 is the US equivalent guide for application).
   • UK: BSI (BS EN 60099 series).
   • Germany: VDE (DIN EN 60099 series).

3. Technical Libraries:

   • University libraries with engineering departments often hold subscriptions to the IEC database.

Warning regarding "Free" PDFs: Downloading copyrighted standards from unauthorized file-sharing sites is illegal and risky. These files are often outdated, incomplete, or contain malware.

How to Stay Updated on Changes Without Re-buying Full Standards

IEC releases three types of updates:

1. New edition – Complete rewrite (every 5–10 years).
2. Amendment (AMD) – Technical changes; inserted into the base standard.
3. Corrigendum (COR) – Typographical or minor technical fixes.

To track updates for IEC 61000-4-30 without repurchasing:

• Sign up for IEC Change Notification Service (free via the webstore).
• Use IEC Alert – email alerts when a standard you follow is revised.
• Many national bodies offer "standards update" subscriptions for ~50€/year per standard family.
