本标准规定了本试验箱中臭氧浓度的测定方法。 此外，本标准适用于三种方法，如紫外吸收法（测量方法A）、仪器法（测量方法B）和湿化学法（测量方法C）。然而，紫外线吸收法是臭氧浓度校准的参考方法，用于仪器法和湿化学法的校准。

This Standard specifies the methods for the determination of ozone concentration in test chamber. Moreover, this Standard is applied to three types of method such as the ultraviolet absorption method (Measuring method A), the instrumental method (Measuring method B) and the wet chemical method (Measuring method C). However, the ultraviolet absorption method is the reference method for the calibration of ozone concentration and used for the calibration of the instrumental method and the wet chemical method.
