Scope

This part of GB/T 18851 specifies the discontinuity of the surface opening of the tested material (eg cracks, heavy skin, folds, pores and not
Penetration detection method for fusion, etc.). This method is mainly used for metal materials, but can also be used for other materials as long as these materials are not porous.
And it is inert with respect to the detection medium. Examples of the material to be inspected include castings, forgings, welds, ceramics, and the like.
The term "discontinuous" as used in this section includes all acceptable or unacceptable meanings that have not been assessed.
GB/T 18851.2 and GB/T 18851.3 specify the measurement and monitoring methods for the practical performance of penetration testing products.
