Electromagnetic compatibility standards for vacuum pressure switches

The electromagnetic compatibility standards for vacuum pressure switches mainly involve basic standards, general standards, product category standards and special standards. The following is a detailed explanation:

Basic standards

The basic standard serves as the foundation for formulating other EMC standards. It describes EMC phenomena, stipulates the testing methods, equipment and arrangements for electromagnetic disturbance emission and immunity, and defines the test grades and performance criteria, but does not involve specific products. For example, the IEC61000-X-X series of standards provide a basic framework and general methods for electromagnetic compatibility testing.

General standard

General standards are classified according to the environment in which products are used, stipulating at which ports the equipment should undergo transmission and immunity tests, including AC and DC power ports, signal and data line ports, casing, grounding points, etc., and also specifying the basic standards that can be followed. For example:

EN50082-1: General Standard for Environmental Immunity in Residential, Commercial and Light Industrial Areas.

EN50082-2: General Standard for Environmental Immunity in Industrial Zones.

EN50081-1: General Standard for Environmental Emissions in Residential, Commercial and Light Industrial Areas.

EN50081-2: General Standard for Emissions in Industrial environments.

Product category standards and specific standards

Product category standards and specialized standards are formulated for the EMC testing of certain product series and specialized products. They often refer to the contents of basic standards and, at the same time, make more detailed regulations on testing based on the particularity of the products. For the disturbance emission test, it stipulates the disturbance emission limit of the product. For the immunity test, it stipulates the test grades and performance criteria that the product should achieve. For example:

CISPR11/EN55011: Launch Requirements for ISM engineering medical equipment.

CISPR22/EN55022: Emission Requirements for ITE information technology equipment.

CISPR24/EN55024: Interference immunity requirements for ITE information technology equipment.

GB6833: Specification for Electromagnetic Compatibility Tests of Electronic Measuring Instruments.

Specialized product EMC standards are usually included in the general-purpose standards for a specific product rather than forming a separate EMC standard. For instance, the EMC standards for computers are included in the "General Technical Conditions for Micro Digital Electronic Computers", which encompasses electromagnetic compatibility testing items and is required to be conducted in accordance with GB6833.2 to GB6833.6 and GB9254.
