How to comply with local and international regulations
Successfully complying with both Mexican and international regulations to perform EMC testing on electronic equipment for telecommunications and automotive industries in a Semi-Anechoic Chamber (SAC) was the key challenge for the test house giant Intertek Latinoamérica & Caribbean in Mexico.

The first shipment of our new generation of Tempest and acoustically shielded doors is ready to cross the Atlantic. How did we succeed in developing a door that meets TEMPEST shielding standards while also being acoustically proof? Over four posts, our specialist will guide you through this journey from concept and prototype, including all the challenges we faced, to the final solution.
Vincent van de Vrie (in the photo), our Technical Consultant for Tempest-shielded products, explains the challenges his team faced during the development of the doors.
Vincent: ‘RF shielding requires full contact between the door and the post, whereas acoustic protection needs decoupling to isolate vibrations, which is the opposite. The door acts as a kind of sound box, and the point where the door and the frame meet is the most vulnerable spot for sound insulation. Martijn Fokker, our senior designer, managed to combine rubber profiles with copper fingerstocks to address both threats. These doors are now Sound Transmission Class 55 classified.’
Vincent and Martijn will monitor the shipment and installation to oversee the integration of these doors into the client’s chamber solution and to validate their effects through shielding effectiveness and sound transmission testing.
