There are many kinds of certification for heat shrinkable tubes, such as ROHS certification and UL certification. These certifications are very important reference elements and even necessary conditions in the procurement process of heat shrinkable tubes. Here is a brief introduction of the main heat shrinkable casing certification.

 

1, UL certification:

 

UL is the shorthand of the Underwriter Laboratories Inc.. It was founded in 1894. UL Safety Testing Institute is the most authoritative non-governmental organization in the United States and is also engaged in safety testing and identification in the world. It is an independent, non-profit, professional institution for public safety.

 

For different types of products, UL designs different testing methods, labeled with UL + column name tags, such as UL224.

 

Through the UL authentication product obtains a UL number, may inquire through the website.

 

2, CSA certification

 

CSA is the abbreviation of Canadian Standards Association. Founded in 1919, it is the first non-profit organization in Canada to develop industrial standards. Electronic products and other products sold in the North American market require safety certification. At present, CSA is Canada's largest security certification agency and one of the world's most famous security certification agencies.

 

3, KEMA certification

 

KEMA is the global authority for consultation, testing and certification in the field of energy, serving the entire energy value chain. With the increasing demand for energy in the world today, KEMA plays an important role in ensuring the availability, reliability, sustainability and profitability of energy and related products and processes.

 

4, ROHS certification

 

ROHS is a mandatory standard enacted by EU legislation. Its full name is Restriction of Hazardous Substances. The standard has been put into effect since July 1, 2006. It is mainly used to standardize the material and process standards of electronic and electrical products, making it more conducive to human health and environmental protection. The aim of this standard is to eliminate six substances including lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers in electrical and electronic products, and the content of lead should not exceed 0.1%. The following are the maximum concentrations of six pests in RoHS: cadmium: less than 100 ppm; lead: less than 1000 ppm. Steel alloy less than 3500 ppm, aluminum alloy less than 4000 ppm, copper alloy less than 40 000 ppm; mercury: less than 1000 ppm; hexavalent chromium: less than 1000 ppm.

 

5, SONY SS00259

 

The full name is "Environmental Management Material Management Regulations in Parts and Materials". By defining the environmental management substances contained in the components or components of a product, we can prevent them from mixing into the product and at the same time achieve compliance with national decrees, protect the environment and mitigate the impact on the ecosystem.

 

The heat shrinkable pipes supplied by Suzhou Tongjin Polymer Material Co., Ltd. conform to the European environmental ROHS certification, U. S. UL certification, Canadian CSA certification and SONY SS00259 certification. The product quality of our heat shrinkable tube is reliable, and customers can rest assured to purchase.

Also, there are many kinds of heat shrink tube which ued in diffren situation,so diffrent client need diffrent certification.
