Compliance overview
Scope and applicability
GB 30000.12-2013 applies to the classification and labelling of self-heating substances and mixtures entering the Chinese market. It is designed for chemical manufacturers and distributors who must comply with the UN *Globally Harmonized System of Classification and Labelling of Chemicals (GHS)*. This standard is mandatory for all relevant chemical products and replaces the older GB 20584-2006.
Technical requirements
The standard specifies the terms, definitions, and classification criteria for self-heating substances and mixtures. It divides these substances into two hazard categories based on their potential to undergo oxidative self-heating and spontaneous ignition. Chapter 4 and Chapter 6 are designated as mandatory, outlining the specific classification logic and labelling requirements. The classification is determined by testing different sample sizes (e.g., 25mm and 100mm cubes) at various temperatures (140°C, 120°C, 100°C) and considering the intended packaging volume. For labelling, the standard mandates the use of specific hazard pictograms, signal words, and hazard statements. Category 1 requires the signal word 'Danger', while Category 2 requires 'Warning'. Manufacturers must ensure all label elements, including precautionary statements, are accurately displayed in accordance with the prescribed formats.
Testing methods
Classification testing must be conducted according to test method N.4 as described in Part 33.3.1.6 of the UN *Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria* (Fifth Revised Edition). The standard also mentions screening tests, such as the Grewer Oven test, which may be used if they show sufficient correlation with the classification test results.
FAQs
What products are regulated under GB 30000.12-2013?
GB 30000.12-2013 regulates self-heating substances and mixtures, which are solid or liquid chemicals that can self-heat in contact with air without energy supply, potentially leading to spontaneous ignition.
Are there any updates from the previous version of GB 30000.12-2013?
Yes, this standard replaces GB 20584-2006. Key updates include aligning the technical content with the *UN GHS (Fourth Revised Edition)*, modifying the scope and referenced documents, and restructuring the classification criteria and labelling elements into normative appendices.
How does GB 30000.12-2013 differ from international standards?
GB 30000.12-2013 is technically consistent with the *UN GHS (Fourth Revised Edition)*. It adopts the same classification logic and labelling principles, ensuring alignment with global chemical safety standards while enforcing specific mandatory chapters for the Chinese market.
