Type A test block is suitable for sensitivity comparison test of
two different penetrant flaw detection agents in the case of
non-contamination, and is also suitable for sensitivity comparison
test of the same penetrant flaw detection agent in A different
process. However, due to the large size of the crack, it can not be
used for the performance identification of highly sensitive testing
agent.
Type B test block is mainly used to verify the sensitivity of
operation method and process system; It is usually used against
plastic reproductions or photographs.
Type C test blocks are used for the same purposes as Type A test blocks,
but mainly to identify various penetrant properties and determine
the sensitivity level, because the crack width and depth of Type C
test blocks can be controlled.
Precautions for the use of penetration test blocks
1 The penetration test block shall be cleaned with solvent before
repeated use; Wash with a hard bristle brush and dry for later use.
2 Penetration inspection procedures shall be carried out on the
penetration test blocks in accordance with the instructions of the
manufacturer of the obtained flaw detection agent.
3 Two sets of penetration test blocks shall be used for
fluorescence detection and colored penetrant detection
respectively, because the fluorescence display of fluorescent
penetrant in the test will be affected after the use of colored
penetrant.
4 After use, it should be cleaned thoroughly in time, and all
traces of penetrant flaw detection agent should be eliminated as
far as possible, and then soaked in acetone or alcohol for 1-2
hours. Whether the cleaning is timely and thorough after use
directly affects the service life of the test block.
5 Test blocks should not be placed in a dryer or soaked in
anhydrous alcohol.
6 The test block shall be replaced in time if it is found that the
original feature of the defect cannot be displayed during use
