3.2.1 The subentry project shall be taken as the basic evaluation unit of the quality inspection and evaluation for engineering. Based on the evaluation on the subentry project, the part project and the unit project are evaluated by grades.
3.2.2 The quality inspection and evaluation for the engineering is divided into two grades, i.e., qualified and unqualified.
3.2.3 The quality inspection and evaluation for the subentry project shall include basic requirements, measured item, quality of appearance and quality assurance data.
3.2.4 It is a prerequisite for the quality inspection and evaluation of the subentry project that the basic requirements pass the inspection.
3.2.5 The measured item is divided into the guarantee item and the general item, and the following requirements shall be met if evaluated as qualified:
1 If the measured item has a specified extreme value, any single inspection value shall not exceed the specified extreme value; otherwise, the deviation of the single inspection value shall not exceed 2 times of the allowable deviation value.
2 The qualification rate of the guarantee item shall not be less than 95%, while that of the general item shall not be less than 85%; any qualification rate if specified otherwise shall be subject to its provisions.
The qualification rate shall be calculated using the following equation:
Qualification rate = (Number of points (groups) that are qualified in the inspection)/(Number of all inspection points (groups))×100% (3.2.5)
