Product Certification

Product certification Scheme which is popularly known as the "SLS Marks Scheme", is a scheme that gives a third party guarantee on quality of a product making a competitive market for manufacturers and to improve confidence in consumers. This scheme enables the SLSI to grant permits to local as well as overseas manufacturers producing goods conforming to Sri Lanka Standards to mark the "SLS" mark on their products.
The Certification Mark on a commodity or product signifies that the commodity or product is consistently manufactured in accordance with the relevant Sri Lanka Standard Specification and with the assurance of optimal quality. Compliance with the requirements of the specification is assured through regular monitoring of the quality assurance system through quality audits carried out by qualified Auditors of the Institution and product testing.
