EMI/EMC-testenEMI/EMC-testen

EMI (electromagnetic interference) is unwanted electromagnetic disturbance that can affect other equipment. EMC (electromagnetic compatibility) is the ability of equipment to work properly in its electromagnetic environment without causing interference to others, which includes limiting its own emissions and tolerating interference from outside.

It typically evaluates how much electromagnetic interference a machine emits, and how well the machine keeps working when exposed to electromagnetic disturbances. The exact tests depend on the machine and the applicable standards, and will be scoped for your project.

The requirements come from the EMC Directive, together with the harmonised standards that apply to the machine. Prazamana's testing verifies machinery against the applicable EU directive and harmonised standards. The specific standards depend on the type of equipment and where it will be used, so these are confirmed when the tests are scoped.

Testing can be scoped for a machine you already have, for example if you need to verify compliance before exporting it to the EU. Whether a particular machine can be tested, and how, depends on its size, installation and operating conditions, so please describe it to the team.

The arrangement is agreed when the tests are scoped, depending on the machine and what needs to be measured. Please contact the team to discuss on-site or other options for your equipment.

The cause of the failure is identified and corrected, typically through design or installation changes such as filtering, shielding, grounding or cable routing, and then the equipment is tested again. Please discuss how Prazamana can help with any corrective work and retesting with the team.

Test records are normally kept in the machine's technical documentation, which supports the CE marking process and the EU Declaration of Conformity. The exact format of reports is agreed for each project, so please ask the team what you will receive.
