Alcance y aplicabilidad

GB 30000.21-2013 applies to the classification and labelling of chemicals that exhibit respiratory or skin sensitization properties. This standard is mandatory for chemical manufacturers and importers in China. It aligns with the UN *Globally Harmonized System of Classification and Labelling of Chemicals (GHS)* (Rev. 4) and replaces the previous GB 20595-2006. It is applicable to substances and mixtures that may cause allergic reactions upon inhalation or skin contact.

Requisitos técnicos

This standard specifies the classification criteria and labelling requirements for respiratory sensitizers and skin sensitizers. It divides these hazards into Category 1, with optional sub-categories Category 1A (strong sensitizers) and Category 1B (other sensitizers) based on evidence weight and severity. For respiratory sensitizers, classification relies on human evidence (e.g., asthma, rhinitis) and, where available, animal data. For skin sensitizers, criteria include positive results from animal tests (e.g., Local Lymph Node Assay, Guinea Pig Maximisation Test) and human diagnostic patch test data. The standard also details the bridging principles for classifying mixtures without whole-mixture test data, utilizing data from similar tested mixtures or component concentrations. Specific concentration limits are established for classifying mixtures containing sensitizing components. Labelling requirements mandate the use of specific pictograms, signal words (Danger for respiratory, Warning for skin), and hazard statements (e.g., H334, H317) as defined in the GHS framework.

Métodos de ensayo

The standard references various testing approaches to determine sensitization. For skin sensitization, it mentions the Local Lymph Node Assay (LLNA), Guinea Pig Maximisation Test (GPMT), and Buehler test. It also references human diagnostic methods like patch tests and bronchial provocation tests for respiratory sensitizers. The overview focuses on the evidence weight approach rather than detailing specific test protocols.

Preguntas frecuentes

What products are regulated under GB 30000.21-2013?

GB 30000.21-2013 regulates chemical substances and mixtures that may cause respiratory or skin sensitization. It applies to all such chemicals manufactured, imported, or used in China.

Are there any updates from the previous version of GB 30000.21-2013?
