- AS 3580.6.1:2023 規(guī)定了使用直讀儀器測定環(huán)境空氣中臭氧的方法。該方法適用于測定環(huán)境空氣中標稱濃度范圍為 0 至 0.5 ppm（體積比）（0 至 1 071 μg/m3，0 °C 和 101.3 kPa）的臭氧。如果需要，現(xiàn)代儀器可以在更大的范圍內(nèi)進行測量
| 術(shù)語 | 描述 |
|---|---|
| 下降時間 fall time | Time interval, after a step decrease in input concentration, between initial instrument response and 95 % of final instrument response. |
| 全量程 full scale | Nominated maximum concentration for which an instrument has been calibrated. |
| 干擾等效 interference equivalent | Positive or negative instrument response caused by a substance other than the one being measured. |
| 滯后時間 lag time | Time interval between a step change in input concentration and the first observable corresponding change in instrument response. |
| 一級校準 level 1 calibration | Two-point instrument calibration using a reference test atmosphere which includes adjustment of instrument gain or zero. |
