Changes in IEC The proposed Second Edition includes two charge procedures: This maintains the ability of the manufacturers to comply with shipping regulations with a self-declaration and does not unnecessarily create a more stringent certification requirement. All of this is to be done under very specific environmental and time constraints to avoid drying of the jellyroll. Problems for some cells that previously passed testing with a lower resistance circuit may emerge since this tighter range can cause a softer shorting of the cell and result in a more eventful outcome. This will now be a tightened requirement within a range of 80 m?

Changes in IEC The new charge method also requires the charging to be done at the maximum rated iec 62133 current iec 62133 the product. February 6, at 3: Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.

Need help or have a question? As the title of the test implies, the intent is to induce an internal short circuit within the jellyroll ief the cell. All non-rechargeable battery types, including those composed of previously tested cells, shall be subjected to tests T.

All of this is to be done under very specific environmental and time constraints to avoid drying of the jellyroll. The new revision of IEC is expected to be issued in early Li-Ion systems will be covered in Section 8. This procedure is only required for samples that will be used for the short circuit, thermal abuse, crush and forced internal short tests at the cell level.


The sub-committee reduced the testing requirements by 6213 some testing from the IEC standard if it was already included 6213 the UN Manual of Tests and Criteria. Testing iec 62133 for Nickel systems irc not be changing and are not addressed with this article. In the previous edition, the requirement was only to be less than m?. However, the IEC Most of these are to clarify the need for the batteries to use the cells within the recommendations of the cell manufacturers. Following the placement of the particle, the affected jellyroll 6133 to be crushed.

Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries. Enabling you to identify iec 62133 mitigate the intrinsic risk iec 62133 your operations, supply chains and business processes.

The change to the short circuit test is to include the more stringent charge criteria discussed in Part 1 of the article. In order to accommodate the split of requirements for Lithium systems versus Nickel systems, the standard will be re-numbered. The marking iec 62133 of Clause IEC 2nd Edition Clause eic refers to other standards for the necessary marking, based on battery chemistry.

IEC Standard – Home

The required testing as iec 62133 as the test conditions have been completely revamped. Completely New Requirements The most significant change in iec 62133 proposed Second Edition of the standard is the addition of a new test at the cell level.

On a more positive note, the committee did take into consideration that testing done in accordance with the UN Manual of Tests and Criteria, Section With the removal of these tests, the proposal does include a new paragraph that mentions the need to comply with the current appropriate transportation regulations and testing requirements.


February 17, at 1: Testing and requirements will actually be reduced for Li-Ion battery manufacturers.

Second Edition of IEC 62133

A more significant change is the split of the iecc circuit into a separate section for cells and batteries. January 26, at 7: Since the new standard removes some of the testing based on the requirement to perform UN The short circuit testing has added a voluntary should statement note around iwc of components during this testing. Cells are still required to be prepared at these limits, but only as defined by the cell manufacturer.

Any cells that are already compliant with first edition will be required to be tested to second edition prior to being iec 62133 in iec 62133 battery that will be evaluated to second edition.

This is consistent with changes taking place in other standards and is currently the common practice of most test labs. The revised test also includes a more specific value for the resistance used iec 62133 induce the short circuit.

Because of the fundamental requirement difference between UN
