Flammable gases (including chemically unstable gases) 2.2.1. Definitions 2.2.1.1. Flammable gas means a gas or gas mixture having a flammable range with air at 20 °C and a standard pressure of 101,3 kPa. 2.2.1.2. A chemically unstable gas means a flammable gas that is able to react explosively even in the absence of air or oxygen. 2.2.2. Classification criteria 2.2.2.1. A flammable gas shall be classified in this class in accordance with Table 2.2.1: Table 2.2.1 Criteria for flammable gases Category Criteria 1 Gases, which at 20 °C and a standard pressure of 101,3 kPa: (a) are ignitable when in a mixture of 13 % or less by volume in air; or (b) have a flammable range with air of at least 12 percentage points regardless of the lower flammable limit. 2 Gases, other than those of Category 1, which, at 20 °C and a standard pressure of 101,3 kPa, have a flammable range while mixed in air. Note: Aerosols shall not be classified as flammable gases; see section 2.3. 2.2.2.2. A flammable gas that is also chemically unstable shall additionally be classified in one of the two categories for chemically unstable gases using the methods described in Part III of the UN RTDG, Manual of Tests and Criteria according to the following table: Table 2.2.2 Criteria for chemically unstable gases Category Criteria A Flammable gases which are chemically unstable at 20 °C and a standard pressure of 101,3 kPa B Flammable gases which are chemically unstable at a temperature greater than 20 °C and/or a pressure greater than 101,3 kPa 2.2.3. Hazard Communication Label elements shall be used for substances and mixtures meeting the criteria for classification in this hazard class in accordance with Table 2.2.3.

Figure 2.2.1 Flammable gases Figure 2.2.2 Chemically unstable gases 2.2.4. Additional Classification Considerations 2.2.4.1. Flammability shall be determined by tests or, for mixtures where there are sufficient data available, by calculation in accordance with the methods adopted by ISO (see ISO 10156 as amended, Gases and gas mixtures — Determination of fire potential and oxidising ability for the selection of cylinder valve outlet). Where insufficient data are available to use these methods, test method EN 1839 as amended (Determination of explosion limits of gases and vapours) may be used. 2.2.4.2. Chemical instability shall be determined in accordance with the method described in Part III of the UN RTDG, Manual of Tests and Criteria. If the calculations in accordance with ISO 10156 as amended show that a gas mixture is not flammable it is not necessary to carry out the tests for determining chemical instability for classification purposes. 2.3. Aerosols 2.3.1. Definitions Aerosols, this means aerosol dispensers, are any non-refillable receptacles made of metal, glass or plastics and containing a gas compressed, liquefied or dissolved under pressure, with or without a liquid, paste or powder, and fitted with a release device allowing the contents to be ejected as solid or liquid particles in suspension in a gas, as a foam, paste or powder or in a liquid state or in a gaseous state. 2.3.2. Classification criteria 2.3.2.1. Aerosols shall be considered for classification as flammable in accordance with section 2.3.2.2 if they contain any component which is classified as flammable according to the following criteria set out in this Part: — Liquids with a flash point ≤ 93 °C, which includes Flammable Liquids according to section 2.6; — Flammable gases (see section 2.2); — Flammable solids (see section 2.7). Note 1: Flammable components do not cover pyrophoric, self-heating or water-reactive substances and mixtures because such components are never used as aerosol contents. Note 2: Aerosols do not fall additionally within the scope of sections 2.2 (flammable gases), 2.5 (gases under pressure), 2.6 (flammable liquids) and 2.7 (flammable solids). Depending on their contents, aerosols may however fall within the scope of other hazard classes, including their labelling elements. 2.3.2.2. An aerosol shall be classified in one of the three categories for this Class on the basis of its components, of its chemical heat of combustion and, if applicable, of the results of the foam test (for foam aerosols) and of the ignition distance test and enclosed space test (for spray aerosols) in accordance with Figures 2.3.1(a) to 2.3.1(c) of this Annex and subsections 31.4, 31.5 and 31.6 of Part III of the UN RTDG, Manual of Tests and Criteria. Aerosols which do not meet the criteria for inclusion in Category 1 or Category 2 shall be classified in Category 3. Note: Aerosols containing more than 1 % flammable components or with a heat of combustion of at least 20 kJ/g, which are not submitted to the flammability classification procedures in this section shall be classified as aerosols, Category 1.

Additional Classification Considerations 2.3.4.1. The chemical heat of combustion (ΔΗc), in kilojoules per gram (kJ/g), is the product of the theoretical heat of combustion (ΔΗcomb), and a combustion efficiency, usually less than 1,0 (a typical combustion efficiency is 0,95 or 95 %). For a composite aerosol formulation, the chemical heat of combustion is the summation of the weighted heats of combustion for the individual components, as follows: where: ΔΗc = chemical heat of combustion (kJ/g); wi % = mass fraction of component i in the product; ΔΗc(i) = specific heat of combustion (kJ/g)of component i in the product. The chemical heats of combustion can be found in the literature, calculated or determined by tests (see ASTM D 240 as amended — Standard Test Methods for Heat of Combustion of Liquid Hydrocarbon Fuels by Bomb Calorimeter, EN/ISO 13943 as amended, 86.l to 86.3 — Fire safety — Vocabulary, and NFPA 30B as amended — Code for the Manufacture and Storage of Aerosol Products).’; (9) In section 2.4.2.1, the Note under Table 2.4.1 is replaced by the following: ‘Note: “Gases which cause or contribute to the combustion of other material more than air does” means pure gases or gas mixtures with an oxidising power greater than 23,5 % as determined by a method specified in ISO 10156 as amended.’; (10) Section 2.4.4 is replaced by the following: ‘2.4.4.

Classification criteria 2.5.2.1. Gases under pressure shall be classified, according to their physical state when packaged, in one of four groups in accordance with Table 2.5.1: Table 2.5.1 Criteria for gases under pressure Group Criteria Compressed gas A gas which when packaged under pressure is entirely gaseous at – 50 °C; including all gases with a critical temperature ≤ – 50 °C. Liquefied gas A gas which, when packaged under pressure, is partially liquid at temperatures above – 50 °C. A distinction is made between: (i) high pressure liquefied gas: a gas with a critical temperature between – 50 °C and + 65 °C; and (ii) low pressure liquefied gas: a gas with a critical temperature above + 65 °C. Refrigerated liquefied gas A gas which when packaged is made partially liquid because of its low temperature. Dissolved gas A gas which when packaged under pressure is dissolved in a liquid phase solvent. Note: Aerosols shall not be classified as gases under pressure. See section 2.3.’; (13) In section 2.5.4, the second paragraph is replaced by the following: ‘Data can be found in the literature, calculated or determined by testing.
