Type Approval & EMC
Type Approval
 

In accordance with Sections 5(o), 5(q) and 5(v) of the Sri Lanka Telecommunications Act No. 25 of 1991 as amended TRCSL has statutory duty to:

1.
Specify technical standards and procedures for the provision of telecommunication services;
2.
Approve types of telecommunication apparatus which may be connected to a telecommunication system;
3.
Make and enforce compliance with rules to minimize electro-magnetic disturbances produced by radio communications  emissions.
 
Radio and Telecommunications Terminal Equipment (RTTE) which is to be used in Sri Lanka shouldcomply with a set of national and international regulatory standards and requirements for compatibility and safety.

Individuals and business entities those who intend to import/manufacture/sell/ use RTTE should first ensure that the equipment has been type approved by the Commission for use in Sri Lanka. Applications for Type Approval should be made  in accordance with theRTTE Type Approval Rules 2014.
 

Objectives of Type Approval


The objectives of the type approval are to:

• 
Ensure that RTTE does not cause interference  with  the  operation  of  other  radio communications  services or   telecommunications  networks;
• 
Ensure the operating frequency of RTTE is in conformity with the National Frequency Allocation Tableof Sri Lanka;
• 
Ensure that electromagnetic disturbances generated by RTTE does not degrade the operation of other equipment working in close proximity and  RTTE should  have an acceptable level of immunity to  the electromagnetic disturbances which may occur as a result of the operation of other equipment nearby;
Protect users from RTTE that are non-compatible with the  telecommunications networks in Sri Lanka;
• 
Enable the users become aware of the need to ensure that RTTE conforms to national standards and regulation before procuring;
•  Protect the health and safety of end users or any other individual from harmful emissions that may arise out of connection of RTTE to the telecommunications networks.
  

Exempt from Type Approval

The following RTTE are exempted from type approval for import, manufacture, sale and use in Sri Lanka provided that RTTE should meet the relevant technical specifications as specified by the Commission.
 
1.
Infrared remote control equipment .
2.
A short range infrared remote control equipment includes TV remote control, garage door opener.
3.
RTTE is embedded in Desktop Computers and tablets that use short-range radio technologies .
4.
Transmitting equipment with output power below 50mw.
5.
RTTE is installed in a vehicle as part of it such as car navigation units, remote car keys that use short‐range technologies.
 

Importation of RTTE for own use

Persons (individuals or corporate entities) are allowed to import type approved RTTE for their own use   subject to payment of a fee and other applicable rules and regulations. The permission is only granted to import RTTE that type approved under these rules or does comply with the relevant technical specifications specified by the Commission. Followings are maximum number of quantities that can be allowed to bring into the country subject to Conditions stipulated below.

 

1.
Individuals are permitted to bring total of 5 (five) units in all categories of RTTE within a time period of one year from the date of first importation of the RTTE.
2.
In the case of corporate entities, they are allowed to import a total not exceeding 10 (ten) units in all categories of RTTE within a time period of one year from the date of first importation of the RTTE.
 

Electromagnetic Compatibility

Electromagnetic Compatibility (EMC) means the ability of an electronic device to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbances to anything in that environment.

Generally, the investigation of EMC is categorized into two main areas. The Investigation of:

 

a.
The Radio/Telecommunication equipment has an adequate level of immunity to perform without degradation in the presence of an electromagnetic disturbance; and
b. The electromagnetic disturbing emission it generates does not exceed a level allowing Radio/Telecommunication equipment to operate as intended.
 

These requirements are applicable to all Radio/Telecommunication equipment which may produce electromagnetic disturbance, or to functioning of which such disturbances may affect.

Compliance with EMC requirements should be demonstrated by meeting the applicable EMC standards for both emission and immunity limits. The applicable EMC standards for Radio and Telecommunications Terminal Equipment (RTTE) in Sri Lanka could be downloaded from here.
