This standard establishes a method for the determination of ozone concentration in environment air using ultraviolet spectrophotometry. It is suitable for instantaneous determination and continuous automatic monitoring of ozone in environment air, with a concentration range of 0.003 to 2 mg/m3. Terms include "zero air" and "transfer standard". The principle of the method is to alternately enter the Absorption cell, cuvette, through sample air and zero air, to detect its light transmitance at a wavelength of 253.7 nm, and then calculate the ozone concentration according to Lambert-Beer's law.
