Chapter 2.1

  2.0.2.4 Amend "2.5.3.3.2" to read "2.5.3.3".

  2.1.3.5 Insert the following new paragraphs:

  "2.1.3.5 Assignment of fireworks to hazard divisions

  2.1.3.5.1 Fireworks shall normally be assigned to hazard divisions 1.1, 1.2, 1.3, and 1.4 on the basis of test data derived from Test Series 6 of the United Nations Manual of Test and Criteria. However, since the range of such articles is very extensive and the availability of test facilities may be limited, assignment to hazard divisions may also be made in accordance with the procedure in 2.1.3.5.2.

  2.1.3.5.2. Assignment of fireworks to UN Nos.0333, 0334, 0335 or 0336 may be made on the basis of analogy, without the need for Test Series 6 testing, in accordance with the default fireworks classification table in 2.1.3.5.5. Such assignment shall be made with the agreement of the competent authority. Items not specified in the table shall be classified on the basis of test data derived from Test Series 6 of the United Nations Manual of Test and Criteria.

  NOTE: The addition of other types of fireworks to column 1 of the table in 2.1.3.5.5 shall only be made on the basis of full test data submitted to the UN Sub-Committee of Experts on the Transport of Dangerous Goods for consideration.

  2.1.3.5.3 Where fireworks of more than one hazard division are packed in the same package they shall be classified on the basis of the highest hazard division unless test data derived from Test Series 6 of the United Nations Manual of Test and Criteria indicate otherwise.

  2.1.3.5.4 The classification shown in the table in 2.1.3.5.5 applies only for articles packed in fibreboard boxes (4G).

  2.1.3.5.5 Default fireworks classification table footnote

  NOTE 1: References to percentages in the table, unless otherwise stated, are to the mass of all pyrotechnic composition (e.g., rocket motors, lifting charge, bursting charge and effect charge).

  NOTE 2: "Flash composition" in this table refers to pyrotechnic compositions containing an oxidizing substance, or black powder, and a metal powder fuel that are used to produce an aural report effect or used as a bursting charge in fireworks devices.

  NOTE 3: Dimensions in mm refers to:

- for spherical and peanut shells the diameter of the sphere of the shell;

- for cylinder shells the length of the shell;

- for a shell in mortar, Roman candle, shot tube firework or mine the inside diameter of the tube comprising or containing the firework;

- for a bag mine or cylinder mine, the inside diameter of the mortar intended to contain the mine.
