▍SIRIM Certification

For the security of person and property, Malaysia government establishes product certification scheme and puts surveillance on electronic appliances, information & multimedia and construction materials. Controlled products can be exported to Malaysia only after obtaining product certification certificate and labeling. 

▍SIRIM QAS

SIRIM QAS, a wholly-owned subsidiary of the Malaysian Institute of Industry Standards, is the only designated certification unit of the Malaysian national regulatory agencies (KDPNHEP, SKMM, etc.).

The secondary battery certification is designated by KDPNHEP (Malaysian Ministry of Domestic Trade and Consumer Affairs) as the sole certification authority. Currently, manufacturers, importers and traders can apply for certification to SIRIM QAS and apply for the testing and certification of secondary batteries under the licensed certification mode.

▍SIRIM Certification- Secondary Battery

Secondary battery is currently subject to voluntary certification but it is going to be in the scope of mandatory certification soon. The exact mandatory date is subject to the official Malaysian announcement time.  SIRIM QAS has already started accepting certification requests.

Secondary battery certification Standard : MS IEC 62133:2017 or IEC 62133:2012

▍Why MCM?

● Established a good technical exchange and information exchange channel with SIRIM QAS who assigned a specialist to handle with MCM projects and inquiries only and to share the latest precisely information of this area.

● SIRIM QAS recognizes MCM testing data so that samples can be tested in MCM instead of delivering to Malaysia.

● To provide one-stop service for Malaysian certification of batteries, adapters and mobile phones.

IEC 62660-3:2022 varies from version 2014 as follows. The column of Reasons of Change is inferred from our actual work, which may be worth as reference. The new version mentions a new forced internal shorting test. The new method is to stimulate internal shorting by penetrating to create positive and negative tabs in layer 1 and 2 shorting. The procedure is as followed: Fixation of the cell: After fully charged, fix the cell in the testing tools. The cell shall be electrically isolated from the test bench. The cell and indenter shall move along the perpendicular axis. The indentation position shall be the same as described in forced internal shorting.Connecting the monitoring line: The temperature monitoring line on cell surface, the voltage of the cell, the voltage of cell negative terminal and the intender (the voltage shall be recorded with sample rate of at least 1000Hz);Press the intender to the cell with a constant velocity of 0.01mm/s. The press speed may be faster than 0.01mm/s if a one or two-layer internal short circuit can be achieved. The press should be stopped when a visible abrupt voltage drop is detected, and the intender should be released from the cell and release the press.
