ISO 17168-5:2018标准是一项针对半导体光催化材料的测试方法，旨在评估其在室内照明环境下净化空气的性能，特别是针对甲硫醇去除的测试方法。该标准适用于半导体光催化材料的性能评估和比较，以及室内空气净化设备的性能测试。

该标准规定了测试所需的设备和试剂，包括光源、反应器、甲硫醇气体、气体流量计等。测试过程中，需要将半导体光催化材料置于反应器中，通过光源照射产生光催化反应，将甲硫醇转化为无害物质。测试过程中需要测量甲硫醇的去除率和反应速率等指标，以评估半导体光催化材料的性能。

该标准的实施可以帮助用户选择合适的半导体光催化材料，评估其在室内照明环境下的净化空气性能，为室内空气净化设备的选型和设计提供参考依据。
