为了在最大程度发挥环氧乙烷灭菌功效的同时保证其使用的安全性，目前比较流行的的是把环氧乙烷和惰性气体混合（氟利昂、二氧化碳和氮气），使环氧乙烷活性降低，改变爆炸极限，从而提高使用的安全度。由于2000年以后氟利昂因环保问题被淘汰，而二氧化碳的比重和分子量和环氧乙烷比较相近，因此常用70%的二氧化碳和30%的环氧乙烷的混合气体来进行灭菌。
本标准规定了灭菌用环氧乙烷液化气体的术语和定义、分类、要求、试验方法、检验规则、标志、包装、运输、贮存及安全。
本标准适用于灭菌用环氧乙烷液化气体。产品包括环氧乙烷液化气体和环氧乙烷、二氧化碳按比例混合形成的液化气体。

In order to maximize the sterilization effect of ethylene oxide while ensuring its safety during use, it is currently popular to mix ethylene oxide with inert gases (Freon, carbon dioxide, and nitrogen) to reduce the activity of ethylene oxide, change the explosive limit, and thus improve the safety of use. Due to environmental concerns, Freon has been phased out since 2000, and the specific gravity and molecular weight of carbon dioxide are similar to those of ethylene oxide. Therefore, a mixture of 70% carbon dioxide and 30% ethylene oxide is commonly used for sterilization.
This standard specifies the terminology and definitions, classification, requirements, test methods, inspection rules, labeling, packaging, transportation, storage, and safety of ethylene oxide liquefied gas used for sterilization.
This standard is applicable to ethylene oxide liquefied gas used for sterilization. The product includes liquefied gas of ethylene oxide and liquefied gas formed by mixing ethylene oxide and carbon dioxide in proportion.
