橡胶 硫化或热塑性 - 耐臭氧裂纹 - 第3部分:用于确定实验室试验室中臭氧浓度的参考和替代方法
ISO 1431-3:2017 describes three types of method for the determination of ozone concentration in laboratory test chambers.
Method A?UV absorption: this is the reference method, and is used as the means of calibration for the alternative methods B and C.
Method B?Instrumental techniques:
B1: electrochemical
B2: chemiluminescence
Method C?Wet-chemical techniques:
Procedure I
Procedure II
Procedure III
