LP905 PACKING INSTRUCTION LP905
This instruction applies to UN Nos. 3090, 3091, 3480 and 3481 production runs consisting of not more than 100 cells or batteries and to pre-production prototypes of cells or batteries when these prototypes are transported for testing.

The following large packagings are authorized for a single battery and for a single item of equipment containing cells or batteries, provided that the general provisions of 4.1.1 and 4.1.3 are met:

  1. For a single battery:

    • steel (50A);
    • aluminium (50B);
    • metal other than steel or aluminium (50N);
    • rigid plastics (50H);
    • natural wood (50C);
    • plywood (50D);
    • reconstituted wood (50F);
    • rigid fibreboard (50G).

    Large packagings shall also meet the following requirements:

    1. A battery of different size, shape or mass may be packed in an outer packaging of a tested design type listed above provided the total gross mass of the package does not exceed the gross mass for which the design type has been tested;
    2. The battery shall be packed in an inner packaging and placed inside the outer packaging;
    3. The inner packaging shall be completely surrounded by sufficient non-combustible and electrically non-conductive thermal insulation material to protect against a dangerous evolution of heat;
    4. Appropriate measures shall be taken to minimize the effects of vibration and shocks and prevent movement of the battery within the package that may lead to damage and a dangerous condition during transport. When cushioning material is used to meet this requirement it shall be non-combustible and electrically non-conductive; and
    5. Non-combustibility shall be assessed according to a standard recognized in the country where the large packaging is designed or manufactured.

  2. For a single item of equipment containing cells or batteries: Rigid large packagings conforming to the packing group II performance level, made of:

    • steel (50A);
    • aluminium (50B);
    • metal other than steel or aluminium (50N);
    • rigid plastics (50H);
    • natural wood (50C);
    • plywood (50D);
    • reconstituted wood (50F);
    • rigid fibreboard (50G).

    Large packagings shall also meet the following requirements:

    1. A single item of equipment of different size, shape or mass may be packed in an outer packaging of a tested design type listed above provided the total gross mass of the package does not exceed the gross mass for which the design type has been tested;
    2. The equipment shall be constructed or packed in such a manner as to prevent accidental operation during transport;
    3. Appropriate measures shall be taken to minimize the effects of vibration and shocks and prevent movement of the equipment within the package that may lead to damage and a dangerous condition during transport. When cushioning material is used to meet this requirement, it shall be non-combustible and electrically non-conductive; and
    4. Non-combustibility shall be assessed according to a standard recognized in the country where the large packaging is designed or manufactured.

Additional provision:

Cells and batteries shall be protected against short circuit.
