The cell and battery shall be tightened onto the impact testing apparatus with hard bracket,

and the bracket shall support all the installation surfaces. Each cell or battery shall bear

impacts of the equal size for three times, and these impacts shall be applied along three

mutually perpendicular directions that are orthometric to the cell or battery surface. During

the impact of every time, the acceleration mode of cell or battery shall be.

5.2.3.3 Short circuit

The same as 5.1.3.3.

5.3 Vibration, Impact and Charge Test

5.3.1 Test equipments

This test needs the following equipments. vibration machine, impact testing apparatus,

resistor and voltmeter. The impact testing apparatus shall meet the requirements stated in

38.3.4.2.2.1 of the "UN Recommendations on the Transport of Dangerous Goods--Manual of

Tests and Criteria" (Fourth revised edition).

5.3.3.2 Impact

The same as 5.2.3.2.

5.3.3.3 Charge test

One test cell or battery shall be connected with one non-discharged primary cell or battery of

the same type or one fully charged rechargeable cell or battery in the series connected cell

string, and the electrodes of the test cell or battery shall be inversely connected.

5.4 Internal Short Circuit Test

5.4.1 Test equipments

This test needs the following equipments. the clamping device (jaw vice and hydraulic ram,

etc.) with cleat insulator, the rod with the diameter of its rigid insulation surface being at least

50% of the overall size of minimum cell or being at least 6mm (taking the larger one therein),

and voltmeter.

The same as 5.2.3.2.

5.7 Classification

The lithium cell and battery shall be respectively carried out with the series tests required in

5.1~5.6, and the tests of every series shall be carried out in order. If the lithium cell or the

battery meets all the test requirements listed in Table 1, then this lithium cell or battery shall

be judged as the Class 9 dangerous goods. The lithium cells and batteries related to

transportation as stated in the Special Regulations 188 in Chapter 3 of "UN

Recommendations on the Transport of Dangerous Goods--Model Regulation" (Thirteenth

revised edition) are not applicable to this standard.

6.1 The inspection shall be carried out item by item according to the requirements in

Chapter 4 and Chapter 5 of this standard.

6.2 Inspection conditions of hazardous properties.

The inspection of hazardous properties shall be carried out in case any one of the following

conditions is met.

6.3 Judgment rules.

The tests shall be carried out according to 5.1~5.6 of this standard, and the judgment shall be

carried out according to the test results and the hazardous properties for dangerous goods of

lithium batteries stated in 5.7 of this standard.
