Overview

Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) are critical considerations for any equipment utilizing electrical energy, as they pertain to the generation and mitigation of undesirable electronic noise. A wide range of equipment falls under the purview of EMC/EMI requirements, including consumer electronics, power electronics, automotive components, industrial machinery, medical equipment, telecommunications devices, and more.

BTH is one of the few privately owned independent testing laboratories in Delhi NCR & Haryana, and among a select few in India, accredited for EMI/EMC testing. Their state-of-the-art test facility boasts a 3-meter Semi-Anechoic Chamber (SAC) and a 10-meter open site & shielded room for Conformité Européenne (CE) testing. These facilities are approved by regulatory bodies like the FCC (Federal Communication Commission) & IC (Industry Canada), covering a comprehensive range of standards including CISPR, IEC, and EN standards.

Key accredited tests under EMI/EMC encompass various standards such as CISPR-11, CISPR-13, CISPR-14, CISPR-15, CISPR-16, CISPR-22, IEC 61000-4, EN 55011, EN-55014 & EN-55015. These tests ensure that equipment meets the required electromagnetic compatibility standards, minimizing interference and ensuring reliable operation in diverse environments.

What is EMI/EMC Testing

EMI/EMC Testing, or Electromagnetic Interference (EMI) and Electromagnetic Compatibility (EMC) Testing, is a crucial process ensuring that electrical and electronic equipment operate without causing interference to other devices and are immune to external electromagnetic disturbances. 

A wide range of equipment falls under EMI/EMC requirements, including Consumer Electronics, Power Electronics, Automotive Components, Industrial Machinery, Medical Devices, Telecommunication Equipment, Household Appliances, and more. 

BTHPL, one of the few privately owned independent testing labs in India, offers state-of-the-art EMI/EMC test facilities accredited for various international standards. Their facilities include a 3 Meter Semi-Anechoic Chamber (SAC) and a 10 meter open site & shielded room for Conducted Emissions (CE) testing. These facilities are approved by regulatory bodies such as the FCC and IC.

EMI/EMC testing covers a range of standards including CISPR (International Special Committee on Radio Interference), IEC (International Electrotechnical Commission), and EN (European Norms). Key accredited tests include CISPR standards (CISPR-11, CISPR-13, CISPR-14, CISPR-15, CISPR-16, CISPR-22), IEC 61000-4, and EN 55011, 55014, and 55015.

Overall, EMI/EMC testing ensures that equipment meets regulatory requirements, operates reliably, and does not interfere with other devices or systems, thus guaranteeing safety and performance in diverse environments.
