化学品分类和标签规范 第13部分：遇水放出易燃气体的物质和混合物
GB 30000.13-2013 is a current mandatory Chinese national standard for Rules for classification and labelling of chemicals - Part 13: Substances and mixtures which, in contact with water, emit 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
GB 30000.13-2013 applies to the classification and labelling of substances and mixtures which, in contact with water, emit flammable gases. It is designed for chemical manufacturers and distributors aligning with the UN Globally Harmonized System (GHS) (Rev. 4). This standard is mandatory for chemical products entering the Chinese market that exhibit water-reactive properties. It does not apply to substances or mixtures whose chemical structures do not contain metals or metalloids, or those known to form stable mixtures with water.
Technical requirements
The standard establishes the criteria for categorizing water-reactive chemicals into three hazard classes based on the rate of flammable gas emission. Category 1 covers substances that react violently with water at ambient temperature, potentially exhibiting spontaneous ignition, or releasing gas at a rate of ≥10 L/kg per minute. Category 2 includes substances releasing gas at a maximum rate of ≥20 L/kg per hour, while Category 3 applies to those releasing ≥1 L/kg per hour, provided they do not meet the criteria of higher categories. The standard mandates specific labelling elements for each category, including hazard pictograms, signal words, and hazard statements. Manufacturers must ensure that labels accurately reflect the assigned hazard category using the prescribed signal words—either 'Danger' for Categories 1 and 2, or 'Warning' for Category 3. The standard also details the required precautionary statements (P-codes) covering general, prevention, response, storage, and disposal measures to mitigate risks.
Testing methods
Classification testing must be conducted according to the UN Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria (Rev. 5), specifically test method N.5. This test evaluates the reaction of the substance with water and measures the rate of flammable gas evolution to determine the appropriate hazard category. The standard provides a decision logic flowchart to guide classification personnel through the evaluation process.
