Our certification arm covers a wide spectrum of services that includes:

  • Hallmarking of Precious Metal Articles
  • Management Systems Certification
  • Product Certification & Product Listing Scheme

Hallmarking of Precious Metal Articles
Through Singapore Assay Office (SAO), a division of STS, we test and hallmark various types of precious metal jewellery made of gold, platinum, palladium and silver for their precious metal content before the articles are released for sale. SAO is an independent and recognised body that tests and hallmarks in accordance to the guidelines established by the Convention on the Control and Marking of Articles of Precious Metals, or other national requirements as required by the customers.

Management Systems Certification
With a high level of technical expertise, and an unparalleled focus on customer satisfaction, we provide the various management systems certification services to allow organisations to demonstrate their high levels of service/product quality, commitment to the environment and devotion to occupational health & safety, in local and international markets.

  • Quality Management Systems: ISO 9001
  • Environmental Management Systems: ISO 14001
  • Occupational Health & Safety Management Systems: OHSAS 18001
  • Business Continuity Management Systems: SS 540 or BS 25999
  • Energy Management Systems: ISO 50001 / BS 16001

Product Certification & Product Listing Scheme
Our product certification scheme helps manufacturers and traders demonstrate their commitment and compliance to safety and performance requirements of their products, in accordance to national or international standards. Certificate of conformity will be issued once products meet the required standards. Our STS Product Listing Scheme (PLS) includes certifi ed products regulated by Singapore Civil Defence Force (SCDF).


This scheme involves safety and performance of products in accordance to the national and international standards. Certificate of Conformity will be issued once products meet the required standards.

 
Singapore Fire Safety & Shelter Department (“FSSD”) regulated products are specified in the list of products under STS-PLS ISO System 2, ISO System 5 and ISO System 7.
 
ISO System 5 – This PLS system entitles Certificate and “STS Listed” mark. ISO System 5 scheme consists of Type Test representative of a sample of production, inspection of factory quality management system (to ISO 9001) and routine surveillance of the management system and samples of the product, and if necessary, market surveillance. Depending on the relevant authority’s requirement, the “STS Listed” marks are by label issued by STS or by printing of label on products by the applicant. Due to their nature, some products will be issued with Declaration of Compliance instead of label.
 
 
• ISO System 7 – This PLS system entitles Certificate and “STS Listed” mark. ISO System 7 scheme consists of Type Test representative of a sample of production and subsequent batch inspection/testing. The “STS Listed” marks are by label issued by STS. The labels are issued according to the size of the batch and upon condition that the batch has passed the batch testing /inspection. Due to their nature, some products will be issued with Declaration of Compliance instead of label.
 
 
• ISO System 2 – This PLS system entitles Certificate. There will be product review /market surveillance.
