Magnetic Particle Oil Dispersion Black Oxide 1503-400

DESCRIPTION

Magnetic Particle Oil Dispersion Black Oxide 1503-400

black magnetic oxide suspended in a highly refined light petroleum oil. The suspension responds to magnetic leakage fields created by discontinuities in ferromagnetic material. Particles rapidly collect at leakage fields producing black indications.

Properties
Particle Colour: Black
Particle Concentration: 1.2 – 2.4 ml (i.a.w AMS 3041 & AMS 3043)
Particle Size: 0.5 - 4.0 μm, with an average size of 1.5μm.
SAE Sensitivity: 6 lines
Suspension Fluid: Clear highly refined light petroleum oil or water
Viscosity: 2.64 cSt ± 5% (ASTM D445 @ 37.8°C±1°C)
Flash Point: ˃95°C (˃200°F)

Special Features
A unique 360° spray valve.
Low background colour for high contrast indication visibility.
Multiple spray patterns for controlled application and comfort.
Particles are easily agitated, fast acting and produce defined indications.
Can be used with both stationary and portable magnetic test equipment.
Aerosols offer convenience and improve reliability.

Instructions
Note: These instructions describe the basic process, but they may need to be amended by the user
to comply with applicable specifications and/or inspection criteria provided by the contracting agency.
1. Clean the test surface and allow it to dry.
2. Apply DUBL-CHEK CP-2 for background contrast.
3. Magnetise the area to be inspected.
4. Ensure continuous agitation of the suspension. If using an aerosol, shake vigorously before
and during inspection.
5. Apply the BO-1 suspension to the test part at approximately 150mm from the surface.
6. Allow the excess oil/water to run off the inspection area.
7. Inspect the surface under visible light.
8. Collections of Black Oxide No.1 particles will reveal discontinuities at the leakage fields.
9. Clean and repeat the process; changing the orientation of the magnetising direction.
Health & Safety
DUBL-CHEK CP-2 is flammable and when packaged within an aerosol is extremely flammable. Use
with adequate ventilation and away from spark, fire or open flames. Avoid prolonged or repeated
contact with skin. Do not breathe gas, fumes, vapour or spray. Consult the MSDS for more Safety
and Health information.
Get medical attention if irritation develops and persists. Ensure that medical personnel are aware of
the material(s) involved and take precautions to protect themselves.
