The terms and definitions defined in GB13690 and the following terms and definitions apply to this document. 3.1
Gases under pressure
Gases filled into receptacles at a pressure equal to or greater than 200 kPa (gauge pressure) at 20°C, or liquefied gases or refrigerated liquefied gases. Pressurized gas includes compressed gas, liquefied gas, dissolved gas, refrigerated liquefied gas, 4 Classification standards
4.1 General requirements for classification and labeling of pressurized gas See GB13690. 4.2 See Table 1 for classification of pressurized gas.
Note: Aerosols should not be classified as pressurized gas, see GB30000.4. Table 1 Classification of pressurized gas
Compressed gas
Liquefied gas
Gases that are completely gaseous when packaged under pressure at 50°C: including all gases with a critical temperature not greater than -50°C. Gases that are partially liquid when packaged under pressure at a temperature higher than -50°C. It is divided into: High-pressure liquefied gas: gas with a critical temperature between 50 and 65°C: a
Low-pressure liquefied gas: gas with a critical temperature above 65°C Gas that is partially liquid when packaged due to its low temperature Frozen liquefied gas
Dissolved gas
Gas dissolved in a liquid solvent when packaged under pressure Note: Critical temperature refers to the temperature above which pure gas cannot be liquefied regardless of the degree of compression GB30000.6—2013
5 Decision logic and guidance
Decision logic and guidance are for reference only. Decision logic and guidance refer to Appendix A. It is particularly recommended that the person responsible for classification study Chapter 4 before and when using the decision logic.
6 Labeling
6.1 Overview
6.1.1 For the labels of pressurized gases, the hazard categories are listed in the order of the designated pictograms, signal words and hazard statements. The hazard types or categories covered by the United Nations "Recommendations on the Transport of Dangerous Goods Model Regulations (Seventeenth 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 pressurized gas label elements is shown in Appendix B. 6.1.2 For the classification standards and label elements for pressurized 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, etc. 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 additional information.
6.2 Hazard pictograms
Hazard pictograms should use black symbols with white backing and a red frame wide enough to ensure that the hazard pictograms, graphic special colors, numbers and minimum length are as specified in the Model Regulations. See Appendix B. 6.3 Signal words
Signal words are words used on labels to indicate the relative severity of a hazard and to alert readers to potential hazards. For pressurized gases use the signal word "Warning". 6.4 Hazard statements A hazard statement is a short description of the hazardous properties of a chemical assigned to a hazard class and category. When appropriate, it is also used to describe the hazardous properties of a chemical. Hazard statements for pressurized gases include the degree of hazard. 6.5 Precautionary statements A synonym (and or pictogram) used to describe the measures recommended to minimize or prevent adverse effects of exposure to the chemical or inappropriate storage or handling of the chemical. There are five types of precautionary statements to meet the requirements: general, prevention, emergency, storage and disposal. Precautionary statements for pressurized gases are shown in Appendix D. 6.6 Product identifiers .6.1 The product identifier should be used on the label and should be consistent with the product identifier used on the Material Safety Data Sheet. If a substance or mixture is listed in the Model Regulations, the correct UN shipping name should also be used on the packaging. 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 cause these hazards. The competent authority may require that the chemical names of all ingredients or alloying elements that may contribute to the hazards of the mixture or alloy be listed on the label. 6.7 Supplier Identification
The label should provide the name, address, and address of the manufacturer or supplier of the substance or mixture. Address and telephone number. 6.8 Examples of labels See Appendix E for examples of labels for pressurized gases. 2 A.1 Decision logic Classification shall be carried out according to the decision logic in Figure A.1. Appendix A (Informative Appendix) Decision logic and guidance Is the substance or mixture a gas? Is the pressure equal to or greater than 200 kPa at 20°C and the container stores a gas or a liquefied gas or a refrigerated liquefied gas? Is the gas dissolved in liquid form under high pressure? Does the gas partially liquefy at low temperatures? Does the gas partially liquefy at temperatures above the product? Does the critical temperature of the gas exceed 65°C? Does the critical temperature of the gas exceed - Is it between 50℃ and 65℃? Is the gas completely gaseous at -50C? Yes

A.2.1 For gases in this category, the following information is required: a) vapor pressure at 50℃;
b) physical state at 20℃ and standard ambient pressure; c) critical temperature.
A.2.2 The above data are required to classify a gas. These data can be found in the literature, calculated or determined by experiments. The Model Regulations already classify most pure gases. For most disposable mixtures, additional calculations are required, which can be very complex.

D.1.2 Coding of hazard statements:bzxz.net
D.1.2.1 For the coding of hazard statements, see Annex 3 of GHS. D.1.2.2 Each hazard statement is assigned a specific alphanumeric code consisting of one letter and three numbers, as follows: The letter "H" (for hazard statement); "2" for physical hazard; "4" for health hazard; and "5" for environmental hazard. The last two numbers correspond to the sequence number of the hazard that can be avoided by the inherent properties of the substance, as follows: Explosive (code 200 to general mixed
230), etc.
210), flammability (code
Unless otherwise specified, all
competent authorities may stipulate that the hazard statements shall appear on the label
. When providing two or more combined hazard statements, the competent authorities may specify that the order in which the combined hazard statements appear
is determined by the manufacturer or supplier at their discretion. D.1.3 Precautionary statements should be marked together with the standard on the label. Additional information, such as instructions for use, may also be provided at the discretion of the manufacturer/supplier and/or competent authority. D.1.3.1 The codes for precautionary statements are shown in GHS Annex 3 D.1.3.2 Precautionary statement codes: D.1.3.2.1 Each precautionary statement is assigned a unique alphanumeric code consisting of 1 letter and 3 digits. The letter \P\ (stands for "precautionary statement") a)
The first digit represents the type of precautionary statement, as follows: b)
"1" represents a general precautionary statement;
"2\ represents a prevention precautionary statement;
\3\ represents an emergency precautionary statement:
"4\ represents a storage precautionary statement;
"5\ represents a disposal precautionary statement;
c) The last two digits (corresponding to the serial number of the precautionary statement). D.1.3.2.2 The precautionary statement code is for reference only. The precautionary statement code is not part of the precautionary statement clause and should not be used to replace the precautionary statement clause.
