Engineering Standardization

Engineering Standardization

The Engineering Standardization Division formulates the National Engineering Standards. These standards are developed through a committee process and a consultative process with the voluntary involvement and the cooperative effort of all interested parties representing consumers, producers, users, public Institutions and independent technical organizations.

The Institution appoints Technical Committees to advice and guides the institution in these activities with the aim of gathering all possible expertise in the best possible way to maximize benefits to the national economy from these Standardization activities.

National standards represent coordinated solutions for use in technology, commerce, trade and administration are intended to achieve:

  • Overall economy in terms of human effort materials, power and other resources in the exchange of goods and services;
  • The protection of consumer interest through adequate and consistent quality of goods and services;
  • Safety, health and protection of life; and
  • Provide a means of expression and of communication amongst all interested parties.

These standards may be specifications for materials or products, they may be codes of practice giving recommended practices in some field of industry, or they may be methods of test, definition of terms or may express some other form of standardization.

In the formulation of Standards, the policy of the Sri Lanka Standards Institution is to be in line with the International Standards and practices as far as practicable. To this effect, International Standards are adopted as Sri Lanka Standards wherever applicable.

In the selection of standards formulation projects priority is given to standards that facilitate internal and external trade and to enhance the international competitiveness of Sri Lankan products with the prime objective of safeguarding the interest of the consumer.

There are more than 4000 Standards relating to products, commodities, materials, processes & practices. Many have been revised to take care of the developments in the new materials, processes and technologies. Such revisions are indicated with the year of revision. Sri Lanka Standards are intended for voluntary adoption by those concerned unless made compulsory by acts and regulations.

Sectoral Commitees

The Council of the SLSI appoints Sectoral Committees covering broad subject areas to advise the SLSI on standards formulationand implementation activities. Sectoral Committees presently in operation are given below:

Electronic Engineering

Electrical Appliances & Accessories

Electric Cables & Conducters

Information Technology

Materials, Mechanical Systems & Manufacturing

Building & Construction Materials

Sectoral Committees are formed from experts in the respective areas representingall stake holders including manufacturers, academia, relevant government institutions, consumers, independent research and testing organizations, and individual experts. Thus a Sectoral Committee constitutes of both members nominated from respective organizations as well as members appointed on a personal capacity.


The division is responsible for the formulation of National Standards on,

  • Agricultural machineries
  • Automotive Industry
  • Construction materials & Industries
  • Electrical Appliances
  • Electric Cables & Conductors
  • Electronics
  • Engineering design codes
  • Environmental Management Systems
  • Energy Management Systems
  • Occupational Health & Safety Management Systems
  • Security Management Systems
  • Information Technology
  • Nano technology
  • Oil & Gas
  • Renewable Energy

Note:- For scientific based Standardization Activities please refer the Standardization (Scientific) Division.

SLSI in consultation with Sectoral Committees may appoint Working Groups to deal with specific standardization projects. Such Working Groups report to the relevant Sectoral Committee.

Meetings of a committee are normally open only to members of the committee. Requests for attendance by visitors for special purposes should be directed in the first instance to SLSI which will issue an invitation in consultation with the Chairman of the Sectoral Committee.

Each standardization project is managed by an Assistant Director / Deputy Director (Engineering) of the Engineering Standardization Division of the SLSI. There are several procedures which are adopted based on the nature and complexity of the subject, availability of data, reference documents, other relevant standards, and information.

Working Groups

SLSI is in consultation with Sectoral Committees may appoint Working Groups to deal with Specific Standardization projects. Such Working Groups report to the relevant Sectoral Committee. Each Standardization Project is managed by an Assistant Director of Engineering Standardization Division of the SLSI. These committees meet about once in a months or more often as necessary

There are several alternative procedures, which are adopted based on the nature and complex city of the subject, availability of data, reference documents, other relevant Standards and information.

What We Do

The core activity of the Engineering Standardization Division is the formulation of National Standards required for the development of the National economy.

The Engineering Standardization Division is responsible for entire progression of National Standard formulation in the field of Engineering discipline In a broad sense, the tasks related to setting National Standards are as follows;

  1. Formulation of New National Standards
  2. Adoption of International Standards
  3. Review of existing Standards - based on the results of review,
    • Reaffirm
    • Revision
    • Amend (Erratum, corrigendum) when there are minor changes
  4. Withdraw Standards when a need arise

In order to increase productivity and maximize the utilization of resources, the Engineering Standardization Division is working with other divisions of the institution to launch the following strategies to achieve its goals.

  • Promote the use and application of National Standards in all spheres of economic and social activities, related to agriculture, food, chemicals, cosmetics, paper and board Packaging, textiles, leather, garments & also certain needs of the society.
  • Participate in International and Regional Standardization Activities to safeguard National interests.
  • Constantly develop and upgrade the institution and its resources.
