a) Gases that are ignitable when the volume fraction in a mixture with air is 13% or less: or 6) Gases that have a flammable range of at least 12 percentage points when mixed with air, regardless of the lower flammable limit. Gases that have a flammable range when mixed with air, other than gases in Category 1, at 20°C and standard atmospheric pressure of 101.3 kPa. Note: Nitrogen and methyl compounds may be considered as exceptions when there are regulations. Aerosols should not be classified as flammable gases, see GB30000.4. Table 2 Classification of chemically unstable gases
Flammable gases that are chemically unstable at 20°C and standard atmospheric pressure of 101.3 kPa Flammable gases that are chemically unstable at temperatures exceeding 20°C and/or pressures above 101.3 kPa 5 Decision logic and guidance
Decision logic and guidance are for reference only. See Appendix A for decision logic and guidance. It is particularly recommended that the person responsible for classification study Chapter 4 before and during the use of decision logics.
6 Labels
6.1 Overview
6.1.1 For the labels of flammable gases, the hazard categories are listed in the order of the designated pictograms, signal words and hazard statements. The hazard classes or categories covered by the United Nations "Recommendations on the Transport of Dangerous Goods Model Regulations" (10th revised edition) (hereinafter referred to as the "Model Regulations") should list the designated corresponding graphic signs for each category on the label. The allocation of flammable gas label elements is shown in Appendix B. 6.1.2 For the classification standards and label requirements for flammable gases, see Appendix C6.1.3 The information required on the label includes hazard pictograms, signal words, hazard statements, precautionary statements, product identifiers and supplier logos. Note: For other label elements that have not yet been standardized, such as precautionary statements, they also need to be included on the label. The competent authority may also require additional information, and the supplier may also add supplementary information.
6.2 Hazard pictograms
Hazard pictograms should use black symbols with white backgrounds, and the red frame should be wide enough to be eye-catching. The hazard pictograms, graphic symbol colors, numbers and minimum sizes specified in the Model Regulations are shown in Appendix B.6.3 Signal words
Signal words are words used on labels to indicate the relative severity of the hazard and to alert readers to potential hazards. For extremely flammable gases, the signal word "Danger" is used. For flammable gases, the signal word "Warning" is used.2
TKANTKAca-
6.4 Hazard statements
GB30000.3—2013
Hazard statements are phrases assigned to a hazard class and category that describe the hazardous nature of a dangerous product and, where appropriate, its degree of hazard. For flammable gas hazard statements, see Appendix D. 6.5
Precautionary statements
A precautionary statement is a word (and/or pictogram) describing the recommended action to minimize or prevent adverse effects resulting from exposure to, or improper storage or handling of, the hazardous product. For this purpose, there are five categories of precautionary statements: general, prevention, emergency, storage and disposal. See Annex D for precautionary statements regarding flammable gases. 6.6 Product identifiers
6.6.1 The product identifier should be used on the label and should be consistent with the product identifier used on the MSDS. If a substance or mixture is listed in the Model Regulations, the correct UN shipping name should also be used on the package. 6.6.2 The label should include the chemical name of the substance. For mixtures or alloys, when acute toxicity, skin or respiratory sensitization or specific target organ toxicity appear on the label, the label should include the chemical composition of all ingredients or alloying elements that may give rise to these hazards. The competent authority may require that the chemical names of all ingredients or alloying elements that may contribute to the hazard of the mixture or alloy be listed on the label. 6.7 Supplier identification
The name, address and telephone number of the manufacturer or supplier of the substance or mixture should be provided on the label. 6.8 Label examples
For examples of flammable gas labels, see Appendix E. 3
GB30000.3—2013
A.1 Decision logic
Appendix A
(Informative Appendix)
Decision logic and guidance
A.1.1 Gas flammability data are required to classify flammable gases. Classification should be carried out according to the decision logic in Figure A.1. Gaseous substances or gas mixtures
Is the gas flammable at 20°C and 101.3kP: standard pressure below the flammable range?
At 20℃ and 101.3kPa standard pressure, if the gas ignites when it occupies 13% or less by volume in a mixture with air, is it a)
irrespective of its lower flammability limit, and mixed with air, has a flammable range of at least b)
12 percentage points?
Figure A.1 Decision logic for flammable gases
Category 2
No graphic symbol
A.1.2 Chemical instability data are required for the classification of a gas as a chemically unstable gas. The classification shall be made according to the decision logic of Figure A.2. ifKAoNrKAca
is the flammable gas or gas mixture
a chemically unstable gas at 20℃ and/or standard atmospheric pressure 101.3kPa?
When the gas pressure is higher than 200 and/or the atmospheric pressure is higher than 101.3kPa, it is a chemically unstable gas.
A.2 Guidance
Decision logic for chemically unstable gases

When the data required for the use of these methods are insufficient, 4.2.2 Chemical instability shall be determined by tests or calculations in accordance with Part 3 of the Manual of Tests and Criteria. If the calculation results according to GB/T 27862 show that the gas mixture is not flammable, the test for determining chemical instability for the classification date does not need to be carried out. A.2.3 Example of classification of flammable gas mixtures based on the calculation results of GB/T 27862. The calculation formula for the flammability (R) of flammable gas mixtures is shown in formula (A.1): A.2.4
Wherein:
Volume fraction of flammable gas. Expressed in %:
The maximum non-flammable concentration of a mixture of flammable gas in nitrogen and air; The first gas in the mixture;
The number of gases in the mixture;
..(A.1)
GB30000.3—2013
K, the equivalent coefficient of an inert gas to nitrogen. When the gas mixture contains an inert diluent gas other than nitrogen, the corresponding coefficient (K,) of the inert gas should be used to adjust the volume of the inert diluent gas to the volume of the diluent equivalent to the volume of nitrogen. A.2.5 The principle of flammability determination is shown in formula (A.2): V
A.2.6 Example: Using the following gas mixture 2% (H) + 6% (CH) + 27% (Ar) + 65% (He) to calculate
A.2.6.1 Determine the equivalent coefficient (K) of the inert gas to ammonia: K, (Ar) = 0.5
K(He) = 0.5
2 Use the K value of the inert gas to calculate the equivalent gas mixture with nitrogen as the balance gas: A.2.6.2
2% (H) + 6% (CH,) + [27% × 0.5 + 65% × 0.5] (N) = 2% (H2) + 6% (CH) + 46% (N) = 54%A.2 .6.3 Adjust the content to 100%:
×［2%（H）+6%(CH4)+46%(N4)I=3.7%（H2)+11.1%（CH4)+85.2%(N4)100
A.2.6.4 Determine the T. coefficient of the flammable gas: T.(H)=5.7%www.bzxz.net
T(CH4)=14.3%
Use the following formula to calculate the flammability of the equivalent mixed gas: R=
R1, so the mixed gas is flammable in air XV_3.7+111
