3 Terms and definitions
For the purpose of this document, the following terms and definitions defined in GB/T 12604 (all parts) and GB/T 20737 shall apply.
3.1
Nondestructive testing, NDT
On the premise of not damaging testing objects, conduct check and testing to the internal and surface structure, nature or state of testing objects by using physical or chemical methods with appropriate equipment according to technical requirements in specification and analyze and evaluate the result.
3.2
Incomplete penetration
The phenomenon that the joint ends are not completely dissolved in welding. For butt weld, it also refers to the phenomenon that the welding depth does not meet the design requirements.
3.3
Lack of fusion
The unbound parts between weld metal and base metal or among weld layers of weld metal, which may be one of the following forms.
a) The sides are lack of fusion;
The ratio of defects to total defects that can be tested by skilled nondestructive testing personnel according to given equipment and process documents on workpieces under given environmental conditions.
4 General requirements
4.1 Testing personnel
4.1.1 Personnel conducting nondestructive testing of pressure equipment shall obtain corresponding nondestructive testing personnel qualifications according to relevant provisions about the review to nondestructive testing personnel of national special equipment.
4.1.2 The qualification of nondestructive testing personnel is divided into class I (primary), class II (intermediate) and class III (advanced).
