NF ISO 23780-1, J38-545-1 (06/2023)

This document specifies a method for ascertaining the performance of continuous monitoring ORT sensors that may be installed in a BWMS or other location on a vessel, taking into account environmental factors associated with conditions on board the vessel. vessel, humidity and temperature variations as well as predictable sea conditions. This document is intended for use by BWMS manufacturers, sensor manufacturers, testing organizations and ship owners in order to check the performance of an ORR sensor unit. This document is intended to provide requirements and recommendations for ORR sensors that use the N,N-diethyl-1,4-phenylenediamine (DPD) method. These requirements and recommendations are applicable to testing of ORR sensor units in the laboratory, prior to installation. This document identifies: — performance characteristics to be defined by manufacturers of ORR sensors used in the processing environment on board ships (e.g. salinity range); — the pre-qualification and performance control procedures to produce documentation on the capabilities of the instruments; — performance monitoring procedures to be used in different environmental conditions.
