International standard comparison of vacuum pressure switches

At present, no unified international standard specifically for vacuum pressure switches has been found. However, from the perspectives of relevant standards and product characteristics, a comparative analysis of some international common norms and standards involved in vacuum pressure switches can be conducted:

Specifications for pressure and vacuum switches

British standard BS 6134-1991 is a specification specifically for pressure and vacuum switches. Although it may not be directly equivalent to international standards, it has certain reference value internationally. This specification may put forward specific requirements for the design, manufacture, testing and other aspects of pressure and vacuum switches, and these requirements may be referred to or borrowed by other countries or regions when formulating relevant standards.

Electromagnetic compatibility standard

For electrical equipment such as vacuum pressure switches, electromagnetic compatibility is an important consideration factor. The GB/T11022-2011 standard is equivalent to the relevant provisions of IEC62271-1. which puts forward requirements for the electromagnetic compatibility of switchgear, including interference emission tests for the main circuit, auxiliary circuit and control circuit, etc. These requirements help ensure the stability and reliability of vacuum pressure switches in electromagnetic environments. Although this standard is not specifically for vacuum pressure switches, as a type of electrical equipment, vacuum pressure switches also need to meet similar electromagnetic compatibility requirements.

General technical requirements

Some international standards or specifications may stipulate the general technical requirements for electrical equipment such as vacuum pressure switches, such as rated voltage, rated current, insulation level, and mechanical life. These requirements help ensure the basic performance and safety of vacuum pressure switches.

The differences in standards among different countries and regions

Different countries and regions may have formulated different standards for vacuum pressure switches based on their own industrial foundations, technological levels and market demands. These standards may have differences in details, such as testing methods, performance indicators, safety requirements, etc. Therefore, when choosing and using vacuum pressure switches, it is necessary to pay attention to whether they comply with the relevant standards and norms of the target market.
