ISO 19652:2018标准是一项测试光催化材料在室内照明环境下对乙醛分解性能的方法。乙醛是一种常见的有害气体，它会对人体健康产生负面影响。光催化材料是一种能够利用光能将有害气体分解为无害物质的材料。该标准的目的是为了评估光催化材料在室内照明环境下对有害气体的分解效果，以便为室内空气净化提供参考。

该标准适用于各种光催化材料，包括半导体光催化材料。测试过程中，需要将光催化材料与乙醛混合，然后在室内照明环境下进行测试。测试过程中需要测量乙醛的浓度变化，以评估光催化材料的分解效果。该标准还规定了测试条件、测试设备和测试方法等方面的要求。

该标准的实施可以为光催化材料的研发和应用提供参考。通过测试光催化材料的分解效果，可以评估其在室内空气净化方面的应用潜力。此外，该标准还可以为光催化材料的质量控制提供参考，确保其分解效果符合要求。
