Telecom Devices

BTH lab is accredited for Testing of Telecom Devices, Equipment & Accessories under IS 13252 under IT & Electronics Equipment by considering the requirements of TEC (Telecom Engineering Centre) under Ministry of Telecom. Accordingly, the test facility has been enhanced to meet the GR & IR requirements as per TEC test specifications that mainly cover Electronics Safety and EMI/EMC Compliance for Telecom products/Accessories.

BTHPL test facility was designated as CAB(Conformity Assessment Body) by TEC(Telecom Engineering Center) DOT(Department Of Telecom) Govt. in india, to examine Telecom Devices’ Operation, Performance & Safety. Telecom facility is equipped with Combined Telecom Equipment Tester (Herman Laboratory Tele-conformance Analyzer). The facility also includes EMC Compliance required for TEC including CISPR 11 and CISPR 22, CISPR 32, ITU Standard Testing and CE Marking facility for all the Telecom Equipment.

As per latest Gazette notification by DOT, "TEC will be implementing mandatory Testing and Certification of Telecom Equipment, prior to sale/import/use in the country, is under consideration in Department of Telecommunications telecom equipments manufacturers are obliged to go for TEC registration by testing in the TEC approved laboratories designated as CABs, who will test and certified the telecom equipments conforming to TEC specification /requirements ”. The Essential Requirements (ER) to be complied for the purpose of certification under this procedure would be:

  1. General Requirements: a) EMI/EMC b) Safety
  2. Security Requirements
  3. Technical Requirements
  4. Other Requirements: SAR, ROHS, IPv6 etc.

Bharat Test House (P) Ltd (BTHPL) has been designated as Conformity Assessment Body (CAB) for Safety EMI/EMC Testing of Telecom Equipment, by Telecom Engineering Center (TEC), Department of Telecommunication, Govt. of India in 2016.

Wireless Devices

Wireless devices have found its wider applications across variety of very high tech products (Keyboard, Scanners, Laptops, and Printers etc.) to very low-end products including electronic toys. Many products operated on electrical power, can be operated through the wireless devices namely Wi-Fi routers/modems, wireless mouse, wireless keyboard, wireless headphones, wireless smart watches, Wi-Fi USB pen-drives, wireless speakers etc primarily for Convenience and Safety of human beings. Now a day, even Pedestal/Ceiling fans can also be operated through the wireless control instead of manual control. Hence, Safety is also a matter of concern since it radiates certain amount of power. To address this issue, BTH lab has also added test facility as per WPC(Wireless Planning and Coordination) requirements under ETA(Equipment Type Approval) to examine operations, performance and safety of wireless devices. The EMC/EMI test lab facility would also cover tests on various low power wireless devices are being widely used in the IT & Electronic where EMC is essential to comply as per WPC requirement products for satisfactory remote operations as per IS/IEC/EN/WPC/TEC requirements.

The current test facility is mainly consisting of testing of Wireless & Bluetooth devices as per WPC, of Ministry of Communication & Information Technology requirements for all wireless equipments, Wi-Fi, Bluetooth devices covering Wi-Fi routers/modems, wireless mouse & keyboard and headphones, wireless smart watches, Wi-Fi USBs, pen-drives, wireless speakers, etc. BTH Lab has the test facility as per WPC open to the domestic & overseas manufacturers who plans to sell their products in India after getting tested and obtaining approval from WPC. WPC ETA Approval is mandatory from WPC for the low power fixed frequency wireless operated devices.
