Escopo e aplicabilidade

This standard applies to the inspection of hazardous properties for miscellaneous dangerous substances and articles (Class 9). It covers the classification of various items, including lithium batteries, asbestos, life-saving appliances, and environmentally hazardous substances. It is essential for manufacturers and transporters of Class 9 dangerous goods entering the Chinese market. The standard aligns with the UN Recommendations on the Transport of Dangerous Goods.

Requisitos técnicos

The standard specifies the classification criteria for Class 9 substances and articles, which are not covered by other hazard classes. This includes items like inhalable fine dusts, lithium batteries, life-saving appliances, and environmentally hazardous substances. For environmentally hazardous substances (aquatic environment), the standard outlines requirements based on acute aquatic toxicity, chronic aquatic toxicity, bioaccumulation, and degradation data. It defines specific threshold limits for classifying substances into Acute Category 1, Chronic Category 1, and Chronic Category 2, depending on whether the substance is rapidly degradable or not. For mixtures, the standard provides a tiered approach to classification, utilizing bridging principles and the summation method to determine the overall aquatic hazard. Manufacturers must accurately classify their mixtures based on the toxicity data of individual components.

Métodos de ensaio

The standard references various testing methods to determine aquatic toxicity and degradation. Key tests include fish acute toxicity tests (e.g., GB/T 21281), bioconcentration tests (e.g., GB/T 21800), and ready biodegradability tests (e.g., GB/T 21801, GB/T 21802). It also mentions the use of OECD test guidelines for data generation.
