Summary of EN 50270 EMC Testing for Electrical Equipment
The EN 50270 standard evaluates electrical equipment for detecting and measuring combustible gases, toxic gases, or oxygen. The standard applies to residential, commercial, and light-industrial environments. The apparatus can be AC, DC, or battery-powered.
The standard test method, EN 50270, applies to devices intended for use in hazardous areas. These areas can contain explosive or potentially explosive atmospheres.
Additionally, this standard is a product standard that is based on the product family standard, EN 61326.
Lastly, EN 50270 does not apply to the following:
- Equipment intended for the detection of dust or mists in air,
- Scientific or laboratory based equipment used for analysis or measurement,
- Equipment used exclusively for process measurement,
- Equipment for medical purposes,
- Equipment used for breath alcohol measurement,
- Equipment intended for the direct measurement of automotive exhaust gases
EN 50270 EMC Testing Program
An EMC test plan is established before testing. The test plan will contain the following:
- Type of equipment,
- The specification of the safety functions,
- The specification of the non-safety functions,
- Specific pass/fail criteria
Configuration of the Equipment During Testing
The electrical apparatus for detecting and measuring gases or oxygen often consists of systems with no fixed configuration. However, the kind, number, and installation of different subassemblies can vary from system to system.
For simulating electromagnetic compatibility conditions, the unit must represent a typical installation as specified by the manufacturer. This relates to both emissions and immunity.
Operating Conditions of the Equipment During Testing
EN 50270 carries out testing within the manufacturer’s specified environmental operating range. The test is also generally carried out within the rated ranges of supply voltage and frequency.
The apparatus must continue to operate as intended during and after the test.
During the test, the degradation of performance is allowed. However, the performance requirements can not exceed by more than a factor of 2. The unit under testing must show a specified fault indication and/or output.
After the test, any degradation in performance must be self-recoverable. The unit must continue to operate as intended. No permanent change of the actual operating state, stored data, or continuous deactivation of the unit is allowed.
The test results of EN 50270 are documented in a comprehensive report. The information documented in this report includes:
- A description of the apparatus including versions of hardware and software,
- The EMC test plan,
- Arrangements of the apparatus for each test,
- Test data, evaluation, and results.
- Test equipment and set-up
