Water Suspension:

The water must be conditioned before adding the Black Oxide No.1 in order to disperse the particles wet the test surface and inhibit corrosion. W5-C is the recommended conditioner and is added at 10g/Lt. Black Oxide No.1 should be added at a concentration of 15g/Lt.

Settlement Test :

The settlement test, using a pear-shaped centrifuge tube, is essential to check the particle concentration and contamination to the suspension. This SHALL be performed on the initial batch, an adjustment made to the concentration, or at each shift change. The Settlement Test methods and particle concentrations can be found in relevant standards. The recommended volume is between 1.2 and 2.5 ml and will vary from one specification to another. The concentration may be adjusted by adding more MPF, water or Black Oxide No.1 as required.

1. Clean the test surface and allow it to dry.

2. Apply DUBL-CHEK CP-2 for background contrast, if required.

3. Magnetise the area to be inspected.

4. Ensure continuous agitation of the suspension.

5. Apply the suspension to the test part at a distance of approximately 150mm from surface.

Preparation:

GW-8 should be used at a concentration of 5 grams/litre of water. For best results, add a small amount of water to the powder and form a slurry prior to addition to the bath. When using the scoop provided with the DUBL-CHEK GW-8, one level scoop treats 3.8L of tap water.

Settlement Test:

The settlement test, using a pear-shaped centrifuge tube, is essential to check the particle concentration and contamination to the suspension. This SHALL be performed on the initial batch, an adjustment made to the concentration, or at each shift change. The Settlement Test methods and particle concentrations can be found in relevant standards. The recommended volume is between 0.15 and 0.25 ml and will vary from one specification to another. (Read the settled particles that are fluorescent using an ultraviolet light.) The concentration may be adjusted by adding more water or GW-8 as required.

Underwater No. 1 is to be added at a concentration of 15 grams/litre of water. The preparation may vary due to customer practice and specific application. The storage reservoir should have mechanical or air agitation to help keep the particles in suspension.

It is recommended that adequate particle concentration for the specific application be checked by use of a magnetic field indicator or by observation of the particles applied to a magnetisation device (i.e., electromagnet yoke leg).

When these particles are used in a saltwater environment, a fresh batch solution should be made daily to prevent corrosion of the particles.
