化学品制造商和检测机构使用该标准来评估气体或气体混合物的燃烧潜力和氧化能力，以确定其危险性分类。该标准帮助选择合适的气缸阀排气口，确保储存和运输安全。它对于全球化学品统一分类和标签制度（GHS）的实施至关重要，为危险物质的警示标签提供数据支持。
AI Summary AI generated
This standard specifies test and calculation methods for the flammability in air and oxidizing ability of gases and gas mixtures, applicable to hazard classification and cylinder valve outlet selection. It determines whether a gas is flammable or highly oxidizing through tests or calculations (e.g., nitrogen equivalence coefficient method). The standard is not applicable under other pressure and temperature conditions, and provides extensive flammability data tables for pure gases and vapors, along with nitrogen equivalence coefficients for inert gases.
本标准规定了气体和气体混合物在空气中可燃性和氧化能力的试验与计算方法，适用于危险性分类及汽缸阀排气口选择。通过试验或计算（如氮等价系数法）判定气体是否易燃或具有强氧化性。标准不适用于其他压力温度条件，并提供了大量纯气体和蒸气的可燃性数据表，以及惰性气体的氮等价系数。
