ISO 6145-11:2005规定了通过使用电化学生成校准组分并引入互补气流来制备校准气体混合物的方法。通过改变气体流动或通过电池电解质的电荷，可以改变气体混合物的组成。通过将相对组合的标准不确定度乘以覆盖系数k = 2获得的校准气体含量U的相对扩大的不确定度不大于5％。 ISO 6145-11:2005中描述的方法旨在用于制备体积分数范围（0.1至250）×10-6的校准气体混合物

ISO 6145-11:2005 specifies a method for the preparation of calibration gas mixtures by using electrochemical generation of a calibration component and introduction into a complementary gas flow. By alteration of the gas flow or the charge passed through the cell electrolyte, it is possible to change the composition of the gas mixture. The relative expanded uncertainty of the calibration gas content, U, obtained by multiplying the relative combined standard uncertainties by a coverage factor, k = 2, is not greater than 5 %. The method described in ISO 6145-11:2005 is intended to be applied to the preparation of calibration gas mixtures in the volume fraction ranges (0,1 to 250) x 10-6.
