ISO 17168-1:2018标准是一项针对光催化材料在室内照明环境下去除硝酸盐气体的测试方法。该标准适用于半导体光催化材料，包括粉末、薄膜、涂层等形式。该标准规定了测试条件、测试方法和测试结果的评价方法。

该标准要求在室内照明环境下进行测试，测试条件包括温度、湿度、光照强度等。测试方法包括将光催化材料与硝酸盐气体接触，通过检测硝酸盐气体的去除率来评价光催化材料的性能。测试结果的评价方法包括硝酸盐气体去除率、反应速率常数等指标。

该标准的实施可以帮助人们了解光催化材料在室内照明环境下去除硝酸盐气体的性能，为空气净化技术的发展提供参考。同时，该标准也可以为光催化材料的研发和生产提供技术支持。

ISO 17168-1:2018标准的实施需要注意以下几点：

1.测试条件应符合标准规定，以保证测试结果的准确性和可比性。

2.测试过程中应注意安全，避免光催化材料对人体和环境造成危害。

3.测试结果应进行科学分析和评价，以便更好地了解光催化材料的性能。

4.该标准只适用于光催化材料在室内照明环境下去除硝酸盐气体的测试，对于其他气体的去除需要采用其他标准进行测试。
