Documentation requirements for electromagnetic compatibility (EMC) testing

Electrical and electronic equipment manufacturers must prepare specific documents before performing EMC testing and provide the documents to the testing agency. EMC test documents can be divided into several groups.

I. Basic documentation for EMC testing

Here, the following types of information must be provided:

· Risk analysis, where applicable

· Usability information, where appropriate

· Software verification and software life cycle information, if relevant

· Product samples submitted for EMC testing

· A brief description of the product's functions and intended use, including name and model

· Description of product model differences

· Product sample status for testing (e.g., prototype and production)

· Number of models

· Dimensions and weight of the device.

II. Power supply and grounding requirements

EEE manufacturers must provide information on power supply and grounding requirements for product samples and auxiliary equipment. For example, such EMC test documentation should include line voltage requirements, frequency requirements, number of power cords, type of power connection, and any special grounding requirements.

III. Configuration Documentation for EMC Testing

The documentation should be able to answer the following questions:

· What line voltage needs to be tested?

· How many product sample configurations will be tested?

· If applicable, how will the product be operated under maximum load conditions within the specified duty cycle?

· How many I/O ports are there?

· How will the I/O ports be used?

· Which is the worst operating mode?

IV. Construction Details

This section of the EMC test documentation should include the following:

· Block diagram, including insulation diagram.

· Accessories.

· PCB layout.

· If applicable, any auxiliary equipment, including spare fuses, special tools for opening the product, or other replaceable parts.

· List of all safety-critical components, including the name, model or model number, manufacturer details, ratings, and applicable safety standards of the safety-related components.

V. Transformers and Chokes

The manufacturer should be able to meet the following information requirements:

· Construction drawing with all part numbers (e.g., core, partitions, and core insulation).

· Installation schematic with rated voltage, resistance, current, lead color/number, wire diameter and integrated fuse.

· Product parts list, including information such as material, type/model, manufacturer, flame rating and certification.

· Test samples.

In addition to all of the above, EMC test documentation should also include failure mode information, usage environment, auxiliary equipment information and software verification information (such as software version, software development requirements and software test plan with test results). In addition, if the electrical product is controlled, monitored or programmed by remote software, the test laboratory should have access to a laptop or PC with pre-installed software. There are not many companies that have the strength to make these standards. Luxshare Testing Agency, which has accumulated 18 years of experience, can meet the requirements.
