Electromagnetic compatibility testing

Electromagnetic compatibility testing

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.

Non-destructive testing - Conventional

Non-destructive testing - Conventional

Non-destructive control laboratory The Non-destructive testing laboratory, offers a wide range of non-destructive tests to its customers. Also known as techniques of "NDT - Non-Destructive Testing" or NDE - Non Destructive Evaluation, the conventional non-destructive testing techniques use the basic principles of visual inspection; radiography; ultrasound and electromagnetism to perform the detection and dimensioning of discontinuities in materials. The application of one or several test techniques allows us to provide fundamental elements for the assessment of the condition and quality of construction. With the exception of industrial radiography conventional non-destructive testing does not provide a record of results, being dependent on the punctual assessment that should always be performed by a qualified technician.

Non-destructive testing - Advanced

Non-destructive testing - Advanced

When the response to needs for inspection of materials, equipment and structures does not fall in the so-called conventional non-destructive testing techniques (NDT), ISQ uses a range of Advanced NDT. Supported by its R&D department, ISQ has its own ability to develop applications of NDT techniques according to the customer needs. These advanced NDT solutions enable you to store and share data, thereby rendering the dissemination and consultation of results fully accessible to all areas involved, e.g. quality, production and maintenance. The increased sensitivity of this kind of tests and the spatial resolution make inspections more feasible and less dependent on the operator, significantly improving the probability to detect discontinuities.
