▍What is TISI Certification?

TISI is short for Thai Industrial Standards Institute, affiliating to Thailand Industry Department. TISI is responsible for formulating the domestic standards as well as participating in international standards formulation and supervising the products and qualified assessment procedure to ensure the standard compliance and recognition. TISI is a governmental authorized regulatory organization for compulsory certification in Thailand. It is also responsible for formation and management of standards, lab approval, personnel training and product registration. It is noted that there is no non-governmental compulsory certification body in Thailand.

There is voluntary and compulsory certification in Thailand. TISI logos (see Figures 1 and 2) are allowed to use when products meet the standards. For products that have not yet been standardized, TISI also implements product registration as a temporary means of certification.

▍Compulsory Certification Scope

The compulsory certification covers 107 categories, 10 fields, including: electrical equipment, accessories, medical equipment, construction materials, consumer goods, vehicles, PVC pipes, LPG gas containers and agricultural products. Products beyond this scope are fall within the voluntary certification scope. Battery is compulsory certification product in TISI certification.

Applied standard: TIS 2217-2548 (2005)

Applied batteries：Secondary cells and batteries(containing alkaline or other non-acid electrolytes – safety requirements for portable sealed secondary cells, and for batteries made from them, for use in portable applications)

License issuance authority:  Thai Industrial Standards Institute

Overview of the Standard
General Specification for the Space-using Li-ion Storage Battery was put forward by China Aerospace Science and Technology Corporation and issued by ShanghaiInstitute of Space Power-Sources. Its draft
has been on public service platform tocanvass opinion. The standard givesregulations on the terms, definition, technical requirement, test method, quality assurance, package, transportation and storage of Li-ion storage battery. The standard applies for the space-using li-ion storage battery (hereinafter referred to as “Storage Battery”).
Requirement of the Standard
Appearance and markThe appearance should be intact; the surface should be clean; the parts and
components should be complete. There should be no mechanical defects, no extras and other defects. The product identification shall include the polarity and traceable product number, where the positive pole is represented by “+” and the negative pole isrepresented by “-”.
Dimensions and weightThe dimensions and weight should be consistent with the technical specifications of thestorage battery.AirtightnessThe leakage rate of the storage battery is not more than 1.0X10-7Pa.m3.s-1; after thebattery is subjected to 80,000 fatigue life cycles, the welding seam of the shell should not be
damaged or leaked, and the burst pressure should not be lower than 2.5MPa.For the requirements of tightness, two tests are designed: leakage rate and shell burst pressure; the analysis should be on test requirements and test methods: these requirements mainly consider the leakage rate of the battery shell under low pressure conditions and its ability to withstand gas pressure.
