3 Terms and definitions
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.
53 Powders
Powders for the dry technique shall consist of finely divided coloured 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 ISO 9934-1, ISO 9934-2, and 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 International Standard having used the methods detailed. This certificate shall include results obtained and tolerances allowed.BS EN ISO 9934-2 pdf download.
