Groups and Schemes in TEC

Groups in TEC

Groups in TEC refers to the Grouping of Equipments for which TEC Certification is mandatory. Equipments are grouped according to the time and complexity involved in testing the equipment or evaluating test reports. These equipments are divided into three Groups: Group A, Group B and Group C.

Schemes in TEC

Below are the 2 types of Certification Schemes for notified Telecom Equipment:
General Certification Scheme (GCS)
Under this scheme, applicant has to submit test wise compliance along with test reports, in respect of parameters included in Essential Requirements (ERs), from any designated Conformance Assessment Body (CAB).

General Certification Scheme (GCS) is applicable to Group A, Group B and Group C equipment. View / Download the group chart.

Simplified Certification Scheme (SCS)
Under this scheme, applicant has to submit a test wise compliance sheet, along with a Self-Declaration of Conformity (SDoC), in respect of parameters included in ERs. Test reports from CAB are not required to be submitted by applicant or evaluated by TEC.

Simplified Certification Scheme (SCS) is applicable to Group A equipment. View / Download the group chart.

Validity and Renewal

Validity of Certificate

TEC Certification is valid for 5 years from the date of issue. However, for Foreign OEM the Certificate is granted for five years or validity of MOU or AIR letter, whichever is earlier.

Renewal of Certificate

Application for renewal is to be made online along with the renewal fee, at least one month prior to expiry of the current certificate’s validity period.

A certificate shall be renewed if there is no change in the ERs applicable to the equipment, and there is no change in the equipment model.

A fresh certificate valid for another five years shall be issued, indicating the previous certificate number thereon.

TEC may ask for re-testing / re-evaluation of certified telecom equipment and charge the relevant fee, should the need arise to check on the compliance of the equipment to the ERs.

Registration Process
Process of TEC Certification involves following steps:

  • Step-1: Registration on TEC Portal
  • Step-2: Allotment of Testing Lab
  • Step-3: Submission of Samples for Testing
  • Step-4: Receiving of Test Reports
  • Step-5: Submission of Documents & Payment to TEC

Prior to Certification on the TEC Portal

Indian OEM

Any Executive of the Indian OEM / Brand owner needs to be made Authorized Signatory through Authorization Letter from his company for TEC related responsibility.

Foreign OEM

Foreign manufacturer is required to nominate an Indian business organization as its Authorized Indian Representative and Signatory (AIR). Any Executive of this company, located in India, can become AIR.
Note – EVTL INDIA can become the AIR for Foreign OEM, if it does not have any other arrangement.

Placing TEC Logo on the product
TEC labelling requirements consist of:

  • Logo on the body of equipment at a prominent location.
  • Indication of equipment conforming to ERs in its technical document.
  • Certification e-label applicable only in case of mobile handset and tablets.
  • Size of TEC logo may be reduced or enlarged maintaining the aspect ratio.

Certificate Modification

Without Re-Testing

Change or modifications performed on the certified equipment that do not affect compliance with approved Essential Requirements will require certificate modification without going through the process of testing. Examples of such modifications are:

  • Change in model number / name arisen due to change in size, shape, colour or enclosure of equipment.
  • Change in model number without affecting the hardware design.
  • Change in ownership / structure / address of company holding the certificate for the equipment.
  • Inclusion of name of a new Associated Model not originally available on the existing certificate, but covered by BoM already submitted.

After examination of the application TEC will issue a new certificate reflecting the changes.

With Re-Testing

Any other modifications performed on the certified equipment that affects its conformance with approved Essential Requirements will require fresh certification. Some examples (not limited to the following) of such modifications are:

  • Addition of new network interface card.
  • Change in the existing network interface card.
  • Inclusion of a new Associated Model neither originally mentioned on the existing certificate, nor covered by BoM of certified model.
  • Inclusion of a new chasses, interface module or unit in the family of already certified equipment.

The modified equipment shall be sold or used only after fresh certificate is issued by TEC.

A change in software, by way of major revision / minor revision / patch / bug fix / update does not necessarily call for certificate modification, unless the change has resulted in non-conformity or non-compliance to ERs, to which the equipment was earlier compliant. The OEM himself is responsible for ascertaining the same and applying for certificate modification, should such a need arise.

Non Conformity and Contraventions
If it comes into the notice of TEC that an uncertified equipment or certified equipment with unauthorized modifications or equipment whose certification has expired is being sold / used or intended to be sold / used, such equipment will be required to undergo the mandatory certification within one hundred and eighty days from the date of notice of violation.

In case certification is not obtained for such telegraph within stipulated timeframe, TEC may order to take custody of all such equipment and destroy them.

Testing Sample Return Policy
The tested samples have to be collected back after 3 months and before 4 months from the date of issue of test report. After 4 months, the lab reserves the right to destroy the sample as per its policy and no claim will be entertained afterwards.

Further, the sample may be partially or fully damaged during the testing. Lab or EVTL INDIA will not entertain any claim regarding this.
