Magnaflux 14AM Fluorescent Particles

INSTRUCTIONS FOR USE

Use 14AM with appropriate magnetization procedure and equipment. For best results, all components, parts, or areas to be tested should be clean and dry prior to testing to provide an optimal test surface and reduce particle suspension contamination. Particle suspension must be properly mixed and continuously agitated when in use to ensure uniformity and concentration.

14AM Aerosol: Shake the can well before use and occasionally during application to ensure proper particle suspension. Hold the can 7 to 9 inches (18 to 24 cm) from the area to be tested. Using the continuous or residual application method, spray particle suspension over the test area until it is completely covered. Inspect under ultra-violet black light. Use in a well-ventilated area. To verify particle concentration, perform a sensitivity check using a known test standard prior to inspection.

14AM Liquid: The suspension can be applied by gently spraying or flooding the area to be tested using the continuous or residual application method. Inspect under ultra-violet black light. Check particle concentration before use.

14AM Liquid Maintenance Recommendations

Magnetic particle suspensions need to be properly maintained to provide consistent results. Suspension concentration and contamination should be monitored at least once a day, or according to applicable specifications. Contaminated suspensions, or those in use for an extended length of time, should be replaced. Properly cleaning all components, parts, or inspection areas before testing helps to significantly reduce particle suspension contamination. Particle concentration should be determined after initial bath preparation and at least once a day, or according to applicable specifications, to maintain the proper level of particles in the suspension. The most widely used method of control is by settling volume measurement in a graduated ASTM pear-shaped centrifuge tube. For testing 14AM, Magnaflux centrifuge tube 8493 is recommended: 100 ml capacity, stem graduated from 0 to 1 mL in 0.05 mL increments.

PREPARATION INSTRUCTIONS

14AM Aerosol: Use as supplied.

14AM Liquid: Use as supplied. Fill tank or container to proper level with 14AM liquid. Mix for a minimum of 15 minutes until the particles are completely and evenly dispersed in the suspension. Check particle concentration before use. Do not add additional Carrier II or mix 14AM with water.

REMOVAL

All components, parts, or inspection areas must be properly demagnetized before cleaning to ensure easy particle removal. Cleaned parts may be treated with a temporary film protective coating if longer corrosion protection is required.
