2005 - ASTM International Accepts Optical Dissolved Oxygen Method - ASTM International Accepts Method D888-05, Standard Test Methods for Dissolved Oxygen in Water. This method lists the luminescence-based dissolved oxygen sensor method (Test Method C) as an acceptable standard method along with the traditional Winkler titration and electrochemical (Clark) methods.
