International EMC/EMI certification (if needed):
The lab should test results can qualify you for CE mark, FCC, AS/NZ, BSMI, Bellcore, Industry Canada, VCA, VCCI, and other approvals.

The lab should be internationally accredited by A2LA (ISO Guide17025) and ANSI (ISO Guide 65). These accreditations bring recognition from the FCC (USA), BSMI (Taiwan), iDA (Singapore), NATA (Australia), New Zealand Ministry of Commerce, SABS (South Africa), HOKLAS (Hong Kong) and others. Additionally, the lab should operate test sites approved for testing by VCCI (Japan) and VCA (Vehicle Certification Agency – UK).

High-technology testing:
To provide accurate, repeatable data, the EMC laboratory must use cutting-edge test facilities and manage the many factors that affect the quality of measurements. For example, the lab may use full-scan height emissions chambers provide ambient free, fast test results. Similarly, the lab may also operate Open Area Test Sites (OATS) which are located in RF quiet areas for emissions testing. Both our full-scan height chambers and OATS provide accurate test results that are not distorted by ambient RF noise. The lab's immunity test sites should use the latest-technology, fully-anechoic chambers. These facilities, also known as Free-Space Rooms, ensure proper evaluation by reducing the risk of over-stress during RF immunity testing.

The Human Factor:
EMC test engineers must understand the application of test standards; the accredited procedures for performing tests; the operation and capabilities of the test equipment; troubleshooting techniques and the fundamentals of excellent customer service. The EMC lab's engineers should have a minimum of a BSEE and / or a minimum of 5 years electronics experience. Their staff must be continually trained, perhaps the training is conducted by senior EMC engineers. If you have a product that needs to meet new or more-complex test requirements, such as Access BPL, “e” mark, powered wheel chairs, ICs and others, the EMC lab should allow for such tests. The experience, attitude and education of the lab's engineers means that they can perform EMC test projects that other labs are not qualified or willing to handle. Their test engineers should also practice efficient and effective EMC troubleshooting techniques. Each lab location should also have access to Senior EMC engineers, capable of addressing any EMC challenge.
