Power quality and electromagnetic compatibility:Standards

Standards

The three types of EMC standards in current use in Europe are basic standards, generic standards and product-specific standards. Basic standards contain the test methods and test levels at limits but do not specify a product type. Product standards contain comprehensive details on how the product should be configured and operated during the test and what parameters should be observed. Generic standards apply in the absence of a product standard and are relevant to all products which may be operated within a defined environment. Both product standards and generic standards may refer to basic standards for their test methods. The important standards in current use in Europe are listed. Those listed in section 14.3.1 and 14.3.2 which are applicable to a particular product or system may be applied by the manufacturer to demonstrate compliance with the EMC Directive.

Generic standards

EN 61000-6-3: Emissions: residential, commercial and light industrial environment EN 61000-6-4: Emissions: industry environment

EN 61000-6-1: Immunity: residential, commercial and light industrial environment EN 61000-6-2: Immunity: industrial environment

Important product standards

EN 50011: Emissions: industrial, scientific and medical equipment EN 50013: Emissions: radio and TV equipment

EN 55020: Immunity: radio and TV equipment

EN 50014-1: Emissions: household appliances and portable tools EN 55014-2: Immunity: household appliances

EN 50015: Emissions: lighting equipment EN 61547: Immunity: lighting equipment

EN 50022: Emissions: information technology equipment EN 55024: Immunity: information technology equipment EN 50091-2: Uninterruptable Power Supplies (UPS)

EN 55103: Professional audio and video equipment EN 60947: Low-voltage switchgear and controlgear EN 61131-2: Programmable controllers

EN 61326: Measurement and control instruments EN 61800-3: Electrical power drives

Other product standards are emerging at a high rate which will mean that reliance on generic standards will diminish significantly in the future.

Basic standards
