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).
4.1.3 Personnel acquiring different qualification classes of different nondestructive
testing methods can only be engaged in nondestructive testing work corresponding to
the method and the qualification.
4.2 Testing equipment and devices
4.2.1 Testing equipment and main devices shall be accompanied with product quality
certification documents.
4.2.2 Testing equipment and devices shall comply with provisions of corresponding
product standard and the performances of them shall meet relevant requirements
specified in the Standard NB/T 47013.2 ~ 47013.13 and certification documents are
required to provide.
4.2.3 For nondestructive testing equipment and devices related to sensitivity used
repeatedly, to ensure that their work performances comply with relevant requirements
of each part of the Standard continuously, the organization undertaking the
nondestructive testing (i.e. testing organization or testing department of enterprises,
hereinafter referred to as the testing organization) shall conduct checking, calibration
or verification regularly (each year or a longer period, according to relevant
requirements of each part of the Standard) and shall specify them in the process rules
of the testing organization.
a) Checking. all nondestructive testing equipment and devices related to sensitivity
listed in the national compulsory verification catalog that shall be conducted with
compulsory testing management shall be sent to qualified legal metrological
verification or authorized metrology institutes for checking;
b) Calibration. regular calibration shall be done to nondestructive testing equipment
documents. According...
