Magnetic partic-
le tester
00, section 5.1.1.
These testers are suitable for complete combined magnetic particle crack inspec-
tion of all ferromagnetic materials. For this purpose an A.C. field circulation can
be combined with a shifted phase A.C. circulation. The two magnetizing
methods are independent from each other and can be applied separately.
To achieve the direction changes of the magnetic field vector necessary for
indication of cracks in any direction, the alternating currents serving as the cur-
rent supply for the different methods of magnetizing are dephased by 120° to
each other.

n.a. Valve lapping paste
This paste, produced by various manufacturers, is a fine gra-
nulate lapping paste for manual lapping of valve seats and
valves. The paste is usually available in 3 different granulate
sizes. Use as per manufacturers instructions.
n.a. MICRONORM abrasive
This abrasive is suitable for local and gradual very fine treat-
ment of steel parts with rust film (propeller shaft). The MI-
CRONORM abrasive contains no harmful substances, is
approved by the competent authorities and guarantees opti-
mum cleaning. The granulates used are of sizes 40 to 60 µ
The achievable surface roughness is between 0.5 and 1 µ,
which corresponds to ultrafine machining of surfaces.
