2.2 Preparation before the test is carried out
The material to be tested
It is decisive for the accuracy of the product that
the material to be tested is checked and
prepared in the correct way.
It is therefore important that the following
recommendations are followed when carrying
out the material test.
Cleaning of the material to be tested
Always clean the material very carefully using a
3M Scotch Brite soft
grinding wheel.
It is important that the material is completely
cleaned from paint, rust etc. The surface to be
tested must be completely "plate clean".
Never use a rough grinding disc or material for
cleaning, since too rough a surface influences
the test result negatively.
Testing exposed/simple material
Clean the surface to be tested, regardless of
material thickness, and carry out the test.
Testing double material (2 or more layers)
when the material thickness is less than
Always expose the material to be tested by
opening the weld etc and removing the part,
which is not to be tested (see picture).
1.2
mm
Testing double material (2 or more layers)
when the material thickness is greater than
Clean or expose the material to be tested and
then carry out the test. It is thus possible to
directly test on a material with a thickness
greater than 1.2 mm, even if the material is
1.2 mm.
