GB/T 33584.5-2017 is the fifth of the six parts of GB/T 33584 and covers the dissolved solids of seawater cooling water. It specifies the water quality requirements for seawater cooling and the gravimetric method for determining the dissolved solids in the cooling water.
It applies to the determination of dissolved solids in seawater cooling water from 10 g/L to 100 g/L. The water quality clause fixes allowable values for calcium ion, magnesium ion, zinc ion, chloride, sulfate, dissolved solids and heterotrophic bacteria, with notes stating where each value comes from.
It cites GB/T 6682 for laboratory water and GB/T 12806 and GB/T 12808 for the volumetric flasks and pipettes, and it warns that the user needs practical laboratory experience. It was issued on 12 May 2017 and has applied since 1 December 2017.
