Electromagnetic compatibility testing

Electromagnetic compatibility (EMC) assesses the ability of electrical and electronic equipment fuction without interfering with other equipment aor radio and telecommunication systems.

About this service:

Testing emission on electromagnetic compatibility (EMC) aims at assessing the possibility of electrical and electronic equipment interfering with other equipment and with radio and telecommunication systems.

The activity of the EMC Laboratory focuses on testing for compliance with the legal requirements, standards and customer specifications.

The laboratory performs testing during all stages of product life, including precompliance testing, final testing, product inspection and validation. This process may involve a product certification body. ISQ has agreements with the Certification Body CERTIF (Association for the Certification) for swifter certification process which issue the licenses based in the ISQ test reports.
