An Updated Guide to IEC EN 61000 6 2

With the latest version published in 2016, IEC 61000-6-2 applies to electrical and electronic apparatus intended for use in industrial environments. It covers immunity requirements in the frequency range 0 Hz to 400 GHz (no tests need to be performed at frequencies where no requirements are specified).

Should I Use IEC/EN 61000-6-2?

As a generic EMC immunity standard, IEC/EN 61000-6-2 is applicable when no relevant EMC family immunity standard exists, and is commonly used for heavy industrial equipment in both indoor and outdoor environments.

Specifically, IEC/EN 61000-6-2 applies to any apparatus intended to be connected to a power network supplied from a high or medium voltage transformer dedicated to the supply of an installation feeding manufacturing or similar plant, and intended to operate in or in proximity to industrial locations. It also applies to any battery operated apparatus intended to be used in industrial locations.

Choosing the Best Standard

While IEC/EN 61000-6-2 is a widely used standard, it isn’t always the most appropriate choice. In some cases, product or industry-specific standards may exist that are required for your equipment, or are a better fit for your product’s features.

Common alternatives to IEC/EN 61000-6-2 include:

• EN 50370-2:2003 Electromagnetic compatibility (EMC) — Product family standard for machine tools
• EN 14010 Safety of Machinery – Equipment for power driven parking of motor vehicles – Safety and EMC requirements for design, manufacturing, erection and commissioning stages
• EN 61326-2-1:2013 Electrical equipment for measurement, control and laboratory use — EMC requirements — Part 2-1: Particular requirements — Test configurations, operational conditions and performance criteria for sensitive test and measurement equipment for EMC unprotected applications

IEC/EN 61000-6-2 may be the most appropriate standard for you if:

• There really isn’t a more specific standard
• It is directly referenced form a more specific standard
• It is intended as a generic product with differing EM environments

Ultimately, the decision will depend on the end use and the type of environment it will be used in. if the environment is unknown, it is expected that the worst case immunity standard (aka IEC/EN 61000-6-2) is used and the generic emission standard for domestic, commercial and light industrial environments is used.
