Magnaflux 14HF Oil-Based Fluorescent Magnetic Particle Ink

Compliance Standards AMS 2641, AMS 3044, AMS 3045, AMS 3046, ASME BPVC, ASTM E1444/E1444M, ASTM E709, ISO 9934-2, MIL-STD-2132, Rolls Royce RRP 58004 (CSS 231), SAFRAN IN 5300, SNECMA DMR70-520 Clean the component before testing to reduce the risk of contamination and provide a suitable test surface. Mix the ink thoroughly and keep it agitated during testing. Apply the ink by spraying, flooding or immersion, depending on your chosen method (see below): Wet continuous method Apply the ink to all surfaces of the component and apply a magnetising current. Remember to stop the flow of ink before the current is switched off, otherwise there is a risk that the force of the ink flood may wash away indications. Wet residual method This method is generally less sensitive than the continuous method and is more susceptible to rapid particle depletion and bath contamination. • Pre-magnetise the part to be tested. • Immerse the part in a bath of the ink. • Remove it and allow it to drain. • Inspect the part. During use, the magnetic content of any ink bath will become depleted so you will need to check your bath strength at least once each day. The most widely-used way of checking an ink’s settlement volume is by using a graduated ASTM pearshaped centrifuge tube. When the settlement volume approaches the lower limit (0.15 ml), check the bath. If the bath appears contaminated, or if it has been in use for a long time, replace the contents. If it is still clean and uncontaminated, add some 14A powder.
