Escopo e aplicabilidade

This standard applies to the classification and labelling of chemical substances and mixtures that exhibit skin corrosion or skin irritation properties. It is designed to align with the United Nations *Globally Harmonized System of Classification and Labelling of Chemicals (GHS)*. Manufacturers and suppliers of hazardous chemicals must comply with this standard to ensure proper hazard communication in the Chinese market.

Requisitos técnicos

The standard establishes the classification criteria for chemicals based on their potential to cause skin corrosion or irritation. It defines skin corrosion as irreversible damage to the skin, while skin irritation refers to reversible damage. The classification process utilizes a weight-of-evidence approach, prioritizing existing human and animal data, structure-activity relationships, and extreme pH values (pH ≤ 2 or pH ≥ 11.5). For mixtures, the standard outlines specific bridging principles and calculation methods when test data for the mixture as a whole is not available. It is mandatory to apply these principles to avoid unnecessary animal testing while accurately determining the hazard category. The standard also details the use of additivity methods based on the concentration of corrosive or irritant components within the mixture. Chapter 4 and Chapter 6 of this standard are mandatory, dictating the precise classification standards and labelling requirements. Compliance with these chapters is legally required for all relevant chemical products. The labelling requirements specify the use of designated hazard pictograms, signal words ("Danger" for corrosion, "Warning" for irritation), hazard statements, and precautionary statements.

Métodos de ensaio

The standard references a tiered testing and evaluation strategy. Key methods include evaluating existing human and animal data, assessing extreme pH and buffering capacity, and utilizing validated *in vitro* skin corrosion tests (such as those outlined in GB/T 27828 and GB/T 27830). If necessary, *in vivo* skin corrosion and irritation tests on animals are prescribed, followed by human patch tests when ethically permissible.

Perguntas frequentes

What products are regulated under GB 30000.19-2013?

This standard regulates chemical substances and mixtures that possess skin corrosion or skin irritation properties, requiring them to be classified and labelled according to the GHS framework in China.

Are there any updates from the previous version of this standard?

Yes, GB 30000.19-2013 replaces GB 20593-2006. The update aligns the technical content with the fourth revised edition of the UN GHS, modifies classification criteria, and restructures the labelling elements and appendices.

Is animal testing mandatory under this standard?

No, the standard encourages a weight-of-evidence approach and the use of validated in vitro alternative methods to minimize animal testing. Animal tests are only considered when existing data and alternative methods are insufficient.
