AS ISO 9555.3:2023 identically adopts ISO 9555 3:1992, which specifies requirements for the use of chemical tracers in discharge measurements by the dilution method. Apparatus and methods of general application are set out in AS 3778.5.1:2022 and are not repeated here, with the exception of those relating specifically to chemical tracers
