14A
Wet Method Fluorescent Magnetic Particles
A highly sensitive magnetic particle powder, 14A fluorescent magnetic
particles are engineered to locate very fine discontinuities in criticalparts and applications. 14A can be suspended in either a petroleumbased vehicle (oil), such as Magnaflux Carrier II, or in water. The
resulting ink gives clear bright yellow/green indications when viewed ina darkened area under UV(A) of peak wavelength 365 nm.
Designed with strong fluorescent properties, 14A magnetic powder ismade with a carefully optimized range of particle sizes & shapes toensure particles move quickly and easily to indications, while minimizing
background and particle clumping. The result is faster inspections withbetter reliability and greater confidence.
A great choice for inspecting a wide range of ferromagnetic parts, 14A
particles meet all major industry and NDT specification requirements,including Aerospace, ASTM, AMS, and ISO 9934.
BENEFITS
Increases indication detection••

Find smaller, finer indications in criticalapplications using the highly sensitive,
strong ferromagnetic 14A particlesOptimized particle size and shape help
particles move freely to stick to a wide
variety of discontinuities with less particle
clumping

Minimizes inspection time••

Clear, bright fluorescent indications form
quickly due to the highly fluorescent,highly mobile particles
Minimal background fluorescence help
indications stand out so inspectors needto spend less time examining each part

Improve inspection consistency and reliability••

Reduced particle clumping helps maintainparticle concentration in the suspension
bath for dependable inspections

Product Data SheetSTORAGE
Store in a well-ventilated area away from magnetizing
equipment and heat sources. Product age, exposure
to elevated temperatures, and/or exposure to astrong magnetic field may adversely affect particle
redistribution.
Protect from sunlight. 14A is a hygroscopic (moistureabsorbing) powder so storage containers should
be tightly sealed when not in use. Cool, dry storage
location is preferred. Refer to Safety Data Sheet for
additional storage instructions.
REMOVALAll components, parts, or inspection areas must be
properly demagnetized before cleaning to ensure
easy particle removal. Cleaned parts may be treatedwith a temporary film protective coating if longer
corrosion protection is required.
PREPARATION INSTRUCTIONS
Oil Bath: Weigh out the appropriate amount of 14A
and add to the appropriate amount of Carrier II.
Mix for a minimum of 15 minutes, until the particles
are completely and evenly dispersed in thesuspension. Check concentration before use.
Water Bath: In water-based suspensions,conditioning agents are required to improveparticle suspendibility, mobility, and surface
wetting.

* Various water conditioners are available, dependingon your region; for example: WA-1, AX-52, WA-2, WA-2B,ZAF-2. Please consult the Product Data Sheets for yourchosen conditioner. If you are unsure, contact a Magnaflux
representative for assistance choosing the best product foryour application.

INSTRUCTIONS FOR USE
Use 14A with appropriate magnetization procedureand equipment. For best results, all components,parts, or areas to be tested should be clean anddry prior to testing to provide an optimal testsurface and reduce particle suspension
contamination. Particle suspension must be
properly mixed and continuously agitated when in
use to ensure uniformity and concentration.
1. Check particle concentration before use.
2. The suspension can be applied by gently
spraying or flooding the area to be tested using
the continuous or residual application method(see ASTM guidelines for more details on theseprocesses).

1. Measure out the appropriate amount of waterconditioner*, add to water and mix for 5
minutes.

3. Inspect under ultra-violet black light.

2. Next, measure out the appropriate amount of
14A magnetic particles and add particles to theconditioned water.

Magnetic particle suspensions need to beproperly maintained to provide consistent results.
Suspension concentration and contamination
should be monitored at least once a day, oraccording to applicable specifications.

3. Add particles directly over the pump for more
rapid dispersion.
4. Mix for 15 minutes or until the particles arecompletely dispersed.
5. Check particle concentration before use.

Maintenance Recommendations

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.

Product Data Sheet
Particle concentration should be determined after
initial bath preparation and at least once a day, oraccording to applicable specifications, to maintainthe proper level of particles in the suspension. The
most widely used method of control is by settlingvolume measurement in a graduated ASTM pearshaped centrifuge tube. For testing 14A, Magnafluxcentrifuge tube 8493 is recommended: 100 ml
capacity, stem graduated from 0 to 1 mL in 0.05 mL
increments.
