What is EMC?

All electronic equipment produces Electromagnetic Fields (EMF) which may cause Electromagnetic Interference (EMI) when not properly addressed.

EMI is an intangible phenomenon, thus Electromagnetic Compatibility (EMC) is used to measure the capability of an electronic equipment to operate in its electromagnetic environment under two general requirements – emission and immunity.

Why is EMC Testing needed?

Standards relating to EMI and EMC have been set by regulatory bodies around the world, limiting the amount of electromagnetic radiation that an electronic equipment can emit depending on the nature of the equipment.

Thus EMC testing is required to ensure that the electronic equipment does not emit large amounts of EMI, and is able to continue functioning in its intended electromagnetic environment, in compliance to the EMC standards and norms.

EMC testing should be conducted regularly, and whenever there are changes made to the structure of the electromagnetic environment, to ensure that compliance is maintained. Regular EMC testing also maintains the health and performance of the electronic equipment.

How we can help

CAST Laboratories offers a comprehensive range of customisable EMC testing services to suit your various EMC needs and requirements, in compliance to international EMC standards or to your in-house EMC standards.
