New generation of TEMPEST shielded doors
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.

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.
SI-EMC, our official representatives in Mexico, developed a customised solution with our team that not only met international standards but also complied with Mexico’s specific national regulations and the requirements for the telecommunications and automotive industries. This makes it the first semi-anechoic chamber in Mexico for a public laboratory that offers component testing for the automotive industry.
Ricardo Morales Aguayo, EMC applications engineer at SI-EMC, led the project, supervised the installation, and designed this chamber.
Ricardo: “In Mexico, telecommunications equipment must comply with local regulations for Telecom and Electromagnetic Compatibility (EMC) testing. These tests need to be conducted within specialised enclosures and facilities, such as Semi-Anechoic Chambers (SAC), to guarantee the reliability and consistency of the measurements.
However, other industries such as medical, automotive, commercial, aerospace, and military also require specialised testing with different configurations, setups, and test levels according to local and international standards.”
