Bac Ford-Bath, Model 531
ASTM D870-2, ISO 2812-2, ASTM D714, ISO 4628-2

Water Immersion test
Test instrument for the execution of an immersion-test to determine the corrosion resistance of a coating.
The container with lid is made of polypropylen, equipped with a thermostat and a circulating pump.
The container is equipped with a grooved base for setting up of samples.

Bac-Ford-Bath, Model 531
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.

  • Bottom drain with external valve.
  • High density polypropylene lid.
  • High density polypropylene support for test plates with 20° inclination.
  • Samples immersed with temperature controlled water in permanent circulation.

Ford Bath complies with method (ISO 2812-2:2007), Renault RNUR 1327, NFT 30053-2, NFT 30 054, and ECCA T-9.

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."
