The magnetic particle materials covered by this specification shall be classified as follows.
5.2 Magnetic inks
Magnetic inks shall consist of finely divided coloured or fluorescent magnetic particles in a suitable carrier liquid.
They shall form a uniform suspension when agitated.
Magnetic inks may be produced from products supplied as concentrates, including paste and powders, or ready for
use.
5.3 Powders
Powders for the dry technique shall consist of finely divided coloured and/or fluorescent magnetic particles.
6 Testing and test certificate
6.1 Type testing and batch testing
Type testing and batch testing of magnetic particle materials shall be carried out in accordance with the
requirements of EN ISO 9934-1, EN ISO 9934-2, and EN ISO 9934-3.
Type testing is carried out in order to demonstrate suitability of a product for the intended use. Batch testing is
carried out in order to demonstrate conformity of the characteristics of a batch to the product type specified.
The supplier shall provide a test certificate showing compliance with this standard having used the methods
detailed. This certificate shall include results obtained and tolerances allowed.
If any changes are made to the detection media, then a new type test shall be performed.
6.2 In service testing
In service testing is carried out to demonstrate the continued performance of the detection media.
7 Requirements and test methods
7.1 Performance
7.1.1 Type testing and batch testing
Type testing and batch testing shall be carried out according to annex A using the reference blocks types 1 or 2 as
described in annex B.
7.1.2 In service testing
In service testing shall be carried out according to annex A using one of the reference blocks types 1 or 2 as
described in annex B or a test block which exhibit similar discontinuities to those normally found in components
typically processed in the equipment.
7.1.3 Contrast aid paints
Type testing and batch testing shall be carried out according to 7.1.1 after having applied the paint in accordance
with the manufacturer instructions and using a type test approved, compatible magnetic ink.
7.2 Colour
The colour of magnetic particles detection media under working conditions shall be stated by the supplier.
The colour of the batch test sample shall not differ from the colour of the type test sample when visually
