GB 30000.3-2013 is a current mandatory Chinese national standard for Rules for classification and labelling of chemicals - Part 3：Flammable gases. It appears in the Electronics compliance cluster with a labeling & classification focus and has an implementation date of Nov 1, 2014.
Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard specifies the classification criteria and labelling requirements for flammable gases and chemically unstable gases. It applies to the classification and labelling of chemical products in accordance with the United Nations *Globally Harmonized System of Classification and Labelling of Chemicals (GHS)*. This standard is mandatory for manufacturers and suppliers dealing with flammable gases in China. It explicitly excludes aerosols, which are covered by GB 30000.4.
Technical requirements
GB 30000.3-2013 establishes the criteria for classifying gases into Category 1 (extremely flammable) and Category 2 (flammable) based on their flammability range and lower flammable limit at 20°C and standard atmospheric pressure. It also defines Category A and Category B for chemically unstable gases that can react rapidly even without air or oxygen. The standard mandates specific labelling elements, including hazard pictograms, signal words (Danger or Warning), and hazard statements. Suppliers must ensure that product identifiers and supplier information are clearly displayed on the label. The standard also references calculation methods for determining the flammability of gas mixtures, utilizing equivalent coefficients for inert gases as detailed in the informative appendices.
Testing methods
Flammability should be determined through testing or calculation according to GB/T 27862. Chemical instability is determined based on the methods described in Part III of the United Nations *Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria*. The standard provides a calculation formula for the flammability of gas mixtures, adjusting volumes of inert dilution gases to equivalent nitrogen volumes to assess the overall flammability.
FAQs
What products are regulated under GB 30000.3-2013?
GB 30000.3-2013 regulates flammable gases and chemically unstable gases. It does not apply to aerosols, which are regulated under a separate standard.
Are there any updates from the previous version of this standard?
Yes, GB 30000.3-2013 replaces GB 20577-2006. The main changes include modifying the standard's name, updating referenced documents to include the 4th revised edition of the GHS, and restructuring the chapters and appendices to align with international guidelines.
How does GB 30000.3-2013 align with international standards?
The technical content of this standard is consistent with the United Nations *Globally Harmonized System of Classification and Labelling of Chemicals (GHS)* (4th revised edition) and the *Recommendations on the Transport of Dangerous Goods*.
