Chapter 6Test Methods 6.1 Oxygen Content Test. 6.1.1* T
47、he oxygen content shall be determined by any instru- ment that can demonstrate an accuracy of 0.5 percent oxy- gen in the presence of nitrogen and argon normally found in ambient air. 6.1.2Calibration standards containing the applicable gas- eous components to an accuracy of 2 percent relative shall
