Fireworks shall normally be assigned to divisions 1.1, 1.2, 1.3, and 1.4 on the basis of test data  derived from Test Series 6 of the Manual of Tests and Criteria.

However:

(a)    waterfalls containing flash composition (see Note 2 of 2.2.1.1.7.5) shall be classified as 1.1G regardless of the results of Test Series 6;

(b)    since the range of such articles is very extensive and the availability of test facilities may be limited, assignment to divisions may also be made in accordance with the procedure in 2.2.1.1.7.2.
 

Assignment of fireworks to UN Nos. 0333, 0334, 0335 and 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 2.2.1.1.7.5. 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.

NOTE 1: The addition of other types of fireworks to column 1 of the table in 2.2.1.1.7.5 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.

NOTE 2: Test data derived by competent authorities which validates, or contradicts the assignment  of fireworks specified in column 4 of the table in 2.2.1.1.7.5 to divisions in column 5 should be submitted to the UN Sub-Committee of Experts on the Transport of Dangerous Goods for information.
 

Where fireworks of more than one division are packed in the same package, they shall be classified on the basis of the most dangerous division unless test data derived from Test Series 6 indicate otherwise.

The classification shown in the table in 2.2.1.1.7.5 applies only for articles packed in fibreboard boxes (4G).

Default fireworks classification table1
NOTE 1: References to percentages in the table, unless otherwise stated, are to the mass of all pyrotechnic substances (e.g. rocket motors, lifting charge, bursting charge and effect charge).

NOTE 2: "Flash composition" in this table refers to pyrotechnic substances in powder form or as pyrotechnic units as presented in the fireworks that are used in waterfalls, or to produce an aural effect or used as a bursting charge, or propellant charge unless:

(a)    The time taken for the pressure rise in the HSL Flash Composition Test in Appendix 7 of the Manual of Tests and Criteria is demonstrated to be more than 6 ms for 0.5 g of pyrotechnic substance; or

(b)    The pyrotechnic substance gives a negative "-" result in the US Flash Composition Test in Appendix 7 of the Manual of Tests and Criteria.

NOTE 3:  Dimensions in mm refer 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.

_____________________
1  This table contains a list of firework classifications which may be used in the absence of Test Series 6  data (see 2.2.1.1.7.2).

An article or a substance may be excluded from Class 1 by virtue of test results and the Class 1 definition with the approval of the competent authority of any ADR Contracting Party who may also recognize an approval granted by the competent authority of a country which is not an ADR Contracting Party provided that this approval has been granted in accordance with the procedures applicable according to RID, ADR, ADN, the IMDG Code or the ICAO Technical Instructions.

 With the approval of the competent authority in accordance with 2.2.1.1.8.1, an article may be excluded from Class 1 when three unpackaged articles, each individually activated by its own means of initiation or ignition or external means to function in the designed mode, meet the following test criteria:

(a)    No external surface shall have a temperature of more than 65 °C. A momentary spike in temperature up to 200 ºC is acceptable;

(b)    No rupture or fragmentation of the external casing or movement of the article or detached parts thereof of more than one metre in any direction;

NOTE: Where the integrity of the article may be affected in the event of an external fire these criteria shall be examined by a fire test, such as described in ISO 12097-3.

(c)    No audible report exceeding 135 dB(C) peak at a distance of one metre;

(d)    No flash or flame capable of igniting a material such as a sheet of 80 ± 10 g/m² paper in  contact with the article; and

(e)    No production of smoke, fumes or dust in such quantities that the visibility in a one cubic metre chamber equipped with appropriately sized blow out panels is reduced more than 50% as measured by a calibrated light (lux) meter or radiometer located one metre from a constant light source located at the midpoint on opposite walls. The general guidance  on  Optical Density Testing in ISO 5659-1 and the general guidance on the Photometric System described in Section 7.5 in ISO 5659-2 may be used or similar optical density measurement methods designed to accomplish the same purpose may also be employed. A suitable hood cover surrounding the back and sides of the light meter shall be used to minimize effects of scattered or leaking light not emitted directly from the source.

NOTE 1: If during the tests addressing criteria (a), (b), (c) and (d) no or very little smoke is observed the test described in (e) may be waived.

NOTE 2: The competent authority referred to in 2.2.1.1.8.1 may require testing in packaged form if it is determined that, as packaged for carriage, the article may pose a greater hazard.
 

A competent authority assigning an article or substance to Class 1 shall confirm that classification with the applicant in writing.

A competent authority classification document may be in any form and may consist of more than one page, provided pages are numbered consecutively. The document shall have a unique reference.

The information provided shall be easy to identify, legible and durable.

Examples of the information that may be provided in the classification documents are as follows:

(a)    The name of the competent authority and the provisions in national legislation under which it  is granted its authority;

(b)    The modal or national regulations for which the classification document is applicable;

(c)    Confirmation that the classification has been approved, made or agreed in accordance with the UN Model Regulations or the relevant modal regulations;

(d)    The name and address of the person in law to which the classification has been assigned and any company registration which uniquely identifies a company or other body corporate under national legislation;

(e)    The name under which the explosives will be placed onto the market or otherwise supplied for carriage;

(f)    The proper shipping name, UN number, class, division and corresponding compatibility group of the explosives;

(g)    Where appropriate, the maximum net explosive mass of the package or article;

(h)    The name, signature, stamp, seal or other identification of the person authorised by the competent authority to issue the classification document is clearly visible;

(i)    Where safety in carriage or the division is assessed as being dependent upon the packaging, the packaging mark or a description of the permitted:

-    Inner packagings

-    Intermediate packagings

-    Outer packagings

(j)    The classification document states the part number, stock number or other  identifying  reference under which the explosives will be placed onto the market or otherwise supplied for carriage;

(k)    The name and address of the person in law who manufactured the explosives and any company registration which uniquely identifies a company or other body corporate under national legislation;

(l)    Any additional information regarding the applicable packing instruction and special packing provisions where appropriate;

(m)    The basis for assigning the classification, i.e. whether on the basis of test results, default for fireworks, analogy with classified explosive, by definition from Table A of Chapter 3.2 etc.;

(n)    Any special conditions or limitations that the competent authority has identified as relevant to the safety for carriage of the explosives, the communication of the hazard and international carriage;

(o)    The expiry date of the classification document is given where the competent authority considers one to be appropriate.
