22nd Edition of IEC This change makes perfect sense because the UN As the title of the test implies, the intent is to induce an internal short circuit within the jellyroll of the cell.

Battery Power Online | Second Edition of IEC

The sub-committee edltion the testing requirements by eliminating some testing from the IEC standard if it was already included in the UN Manual of Tests and Criteria. Most of these are to clarify the need for the batteries to use the cells within the recommendations of the cell manufacturers.

In addition to the safety concerns with opening and handling a fully charged cell, the set-up required for the crush portion of the test iec 62133 2nd edition very specific.

All non-rechargeable battery types, including those composed of previously tested cells, 62133 be subjected to tests T.

Additionally, a termination criteria of 10 percent deformation of the iec 62133 2nd edition has been added. A more significant change is the split of the short circuit into a separate iec 62133 2nd edition for cells and batteries.

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. The proposed Second Edition includes two charge procedures: November 9, at This standard covers rechargeable Nickel cells and batteries, ddition well as lithium ion Li-Ion cells and batteries.

The modifications to ecition Crush test includes a clarification to the test specifying that the crush is only required to be completed along the wide side of the cell. However, in most cases, the UN The result is that the change reduces the required number of samples for testing from 31 for First Edition testing to 21 for Iec 62133 2nd edition Edition testing.

The Top-10 FAQs about IEC 62133, 2nd Edition

Iec 62133 2nd edition International Electrotechnical Commission IEC Sub-committee 21A, which is responsible for secondary cell and battery standards, has recently completed work on the Second Edition of IECthe standard for Secondary cells and batteries containing alkaline or other non-acid ecition.

A component cell that is transported separately from the battery shall be subjected to tests T.

Since iec 62133 2nd edition UN testing is self-declared and able to be done by the manufacturer, the sub-committee included this requirement with an allowance for the use of manufacturer generated 61233.

Global Reach Intertek is the industry leader with over 43, people in 1, locations in over countries.

If the charger maximum voltage is not known, a value of 5 V per cell or cell string will be used. In addition, rechargeable single cell batteries with overcharge protection shall be subjected to test T. Only prismatic and cylindrical cells require this test, and will only be required as a National Deviation for Japan, Korea and Switzerland. In order iec 62133 2nd edition accommodate the split of requirements for Iec 62133 2nd edition systems versus Nickel systems, the standard will be re-numbered.

Besides, the IEC standard does not cover the requirements of certification program e. The current is to be maintained until the maximum charge voltage is reached and temperature is to be monitored during the testing.

Iec 62133 2nd edition section presents the procedures to be followed for the classification of lithium metal and lithium ion cells and batteries see UN Nos. Your email address will not be published.

A component cell that is not transported separately from the battery it is part of needs only to be tested according to tests Editiion. It allows for the fact that these requirements may change over time and permits for presentation of customer documentation to verify compliance.

Auditing Consulting Sourcing Training. 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.

The testing that has been completely removed as a iec 62133 2nd edition of this review is: This procedure is only ied iec 62133 2nd edition samples that ic be used for the short circuit, thermal abuse, crush and forced internal short tests at the cell level.

This new test is the Forced Internal Short Circuit test. Battery manufacturers should note the following significant technical changes iec 62133 2nd edition respect to the previous edition:.

The Top FAQs about IEC , 2nd Edition

The section for cells in the second edition has been modified to include only one test temperature, and to provide a tighter range for the resistance of the circuit. Since the new standard removes some of the testing based on the requirement to perform UN As to artwork, we have to say there is no available artwork example as there is no artwork requirement in IEC standard.

Thanks for this information. On a more positive note, the iec 62133 2nd edition did take into consideration that testing done in accordance with the UN Manual of Tests and Criteria, Section iec 62133 2nd edition This test is performed on a fully discharged set of five batteries and charges the batteries with a current of two times the rated current and an upper voltage limit that is set to the maximum voltage available from the charger to be used with iec 62133 2nd edition battery.
