For the purposes of this document, the terms and definitions given in EN 1330-1, EN 1330-2, EN 1330-7, ISO 12707, and the following apply.
3.1
batch
quantity of material produced during one manufacturing operation having uniform properties throughout and with a unique identifying number or mark
4 Safety precautions
The materials used in magnetic particle inspection and those used in their testing include chemicals that can be harmful, flammable, and/or volatile. All necessary precautions should be observed. All relevant regulations, including national and local regulations pertaining to health and safety, antipollution requirements, etc., shall be observed.
5 Classification
5.1 General
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 can 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 or fluorescent magnetic particles.
