The container is equipped with a grooved base for setting up of samples.
The Bac-Ford-Bath, Model 531, is developed as well as the Machu-Test-Bath for performing immersion corrosion tests on coated test panels.
The construction of the Bac-Ford-Bath is similar to the Machu-Test-Bath.
The test panels are placed directly into the bath with no separate container.
The bottom of the test container is equipped with slots to place the test panels with an angle of 15° or 20°.
The test samples will be immersed in distilled water for some days at a temperature of 40 °C, after the time test samples are removed and the coating is inspected.
Extract from the standard :
" Immersion
procedure
Add to the tank (5.1) sufficient water of
grade 2 purity, as specified in ISO 3696, such that the test panels, when
placed in position on the support (5.3), are immersed for three-quarters of
their length. Commence the circulation and aeration of the water (5.2) in the
tank, adjust the temperature of the water to (40 ± 1) °C and maintain this
temperature throughout the test.
Place
the test panels in the tank for the specified period, rearranging them at
regular intervals of not more than 3 days. Replace the test water if at any
time during the test it becomes turbid or coloured or its conductivity
exceeds 2 mS/m."
