ISO 5364:2016规定了塑料材料和/或橡胶口咽气道的要求，包括带有塑料材料和/或金属制成的加强件的口咽气道。 ISO 5364:2016不适用于金属口咽气道，也不适用于有关口咽气道易燃性的要求。 例如，如果使用易燃麻醉剂、电外科设备或激光，口咽气道的易燃性是公认的危险。由适当的临床管理部门解决，这不在本国际标准的范围内。 ISO 5364:2016不适用于没有内部整体密封机制的喉上气道。

ISO 5364:2016 specifies requirements for oropharyngeal airways of plastics materials and/or rubber, including those with a reinforcement insert made of plastics materials and/or metal. ISO 5364:2016 is not applicable to metal oropharyngeal airways, nor to requirements concerning flammability of oropharyngeal airways. Flammability of oropharyngeal airways, for example, if flammable anaesthetics, electrosurgical units, or lasers are used, is a well-recognized hazard. It is addressed by appropriate clinical management, which is outside the scope of this International Standard. ISO 5364:2016 is not applicable to supralaryngeal airways without an internal, integral sealing mechanism.
