Escopo e aplicabilidade

GB 30000.5-2013 applies to the classification and labelling of oxidizing gases according to the UN *Globally Harmonized System of Classification and Labelling of Chemicals* (GHS). It is applicable to any gas or gas mixture that, by providing oxygen, can cause or contribute to the combustion of other materials more than air can. This standard is mandatory for manufacturers and suppliers of oxidizing gases in China. It replaces the previous standard GB 20579-2006.

Requisitos técnicos

The standard specifies the terms, definitions, and classification criteria for oxidizing gases. It defines an oxidizing gas as any gas that generally provides oxygen, causing or contributing to the combustion of other materials more than air does. For classification, the standard relies on the oxidizing power (OP) of the gas or gas mixture. A gas mixture is classified as an oxidizing gas if its oxidizing power is greater than 23.5%. The calculation method involves determining the oxygen equivalence coefficient of oxidizing gases and the nitrogen equivalence coefficient of inert gases within the mixture. Regarding labelling, the standard mandates specific label elements including hazard pictograms, signal words, and hazard statements. The required signal word for oxidizing gases is "Danger," and the assigned hazard statement is "May cause or intensify fire; oxidizer." Labels must also include precautionary statements covering general, prevention, response, storage, and disposal measures, along with product identifiers and supplier identification.

Métodos de ensaio

Classification and determination of oxidizing gases are based on the testing or calculation methods described in *GB/T 27862*. The standard provides a specific formula to calculate the oxidizing power (OP) of gas mixtures, comparing the sum of the products of oxidizing gas mole concentrations and their oxygen equivalence coefficients against the total adjusted mole concentrations of all gases in the mixture.

Perguntas frequentes

What products are regulated under GB 30000.5-2013?

GB 30000.5-2013 regulates oxidizing gases, which are gases or gas mixtures that can cause or contribute to the combustion of other materials more than air by providing oxygen.

What is the threshold for a gas mixture to be classified as an oxidizing gas under this standard?

According to the standard, a gas mixture is classified as an oxidizing gas if its calculated oxidizing power (OP) is greater than 23.5%.

Are there any updates from the previous version of GB 30000.5-2013?

Yes, GB 30000.5-2013 replaces GB 20579-2006. Key updates include modifying the standard's name, adjusting the scope, and reorganizing chapters and annexes to align with the fourth revised edition of the UN *Globally Harmonized System of Classification and Labelling of Chemicals* (GHS).
