Abstract
Overview
ISO 13964:1998/Amd 1:2024 is an amendment to ISO 13964 (Ultraviolet photometric method) that provides a at room temperature for the mercury-line wavelength . The amendment updates numeric constants, formula parameters and bibliographic references used in the UV photometric determination of ozone in ambient air to reflect current metrological consensus and improved accuracy.
