ASTM B183-18,Standard Practice for Preparation of Low-Carbon Steel for Electroplating.ASTM B183-18 pdf free download.ASTM B183-18 pdf free download.
ASTM B183-18 is intended as an aid to electroplaters in setting up a suitable cleaning cycle preparatory to electroplating of low-carbon steel (Note 1) containing less than 0.35 mass % of carbon and to indicate some of the precautions that must be taken to maintain this cycle in good operating condition.

4. Cleaning Solutions and Apparatus
4.1 All solutions should be subject to chemical control including determinations of the free acid and iron contents of the pickling solutions and acid dips, and such tests of the cleaning solutions as recommended by the manufacturer.
4.2 Based on tests and experience, all solutions should be discarded before they have lost their effectiveness.
4.3 To conserve cleaning and pickling solutions and to ensure continuous operation when heavy production
is involved, doubling of facilities in the same line of operation may be desirable. This arrangement will result in a high degree of contamination of the first of two solutions of the same kind while the second ones will be sufficiently clean to continue to use, It will also reduce the degree of contamination of subsequent solutions, for example, by oil and grease.
4.4 As an alternative to the procedure described in 4.3
cleaner and pickle tanks may be provided with a large dam overflow and a pump having its intake placed about half-way down the overflow dam between the accumulated grease ane oil on top and the settled-out solid dirt at the bottom and having its outlet placed near the bottom of the tank at the end opposite to the dam overflow.
