Abstract
Overview
ISO 7934:1989/Amd 1:1998 is an amendment to the international standard for measuring the mass concentration of sulfur dioxide (SO2) in stationary source emissions using the hydrogen peroxide / barium perchlorate / Thorin chemical method. The amendment (1998) updates parts of the original 1989 procedure to improve accuracy and practical performance based on intermethod comparisons and field experience.
