BAIJIAN - Third party testing organization
3.1 General Provisions
3.1.1 The physical testing of concrete structures in water transportation engineering can be divided into physical verification testing、 engineering quality physical testing、 and structural performance physical testing.
3.1.2 The physical verification testing of concrete structures in water transportation engineering should be carried out in accordance with the relevant provisions of the current industry standard "Quality Inspection Standards for Water Transportation Engineering" (JTS 257) When encountering one of the following situations、 physical inspection of the quality of concrete structure engineering in water transportation engineering should be carried out:
(l) Insufficient inspection quantity of test blocks、 specimens、 and related materials related to structural safety (2) The sampling inspection results of construction quality do not meet the design requirements (3) There are doubts or controversies about the construction quality (4) If an engineering accident occurs、 it is necessary to analyze the cause of the accident and its impact on structural reliability through testing 3.1.4 The monitoring of construction quality during the construction process of concrete engineering can be used for physical inspection of the quality of concrete structures in water transportation engineering When encountering one of the following situations、 physical testing of the current performance of concrete structures in water transportation engineering should be carried out:
(l) The situation specified in Article 3.1.3 (2) Conduct concrete structure evaluation (3) Reliability evaluation of concrete structures before maintenance or change of service conditions (4) Identification of doubts or controversies about the existing engineering quality of concrete structures、 or the need to continue using concrete structures after reaching their designed service life (5) Identification of impacts caused by environmental erosion、 explosions、 impacts、 disasters、 and human factors; (6) Evaluation of concrete structures during operation according to relevant standards The data and conclusions of the physical inspection of concrete structures in water transportation engineering should be true、 reliable、 and effective The physical inspection of concrete structures in water transportation engineering should be based on the purpose and content of the inspection、 combined with the actual situation on site、 to develop a suitable method and a reasonable inspection plan for the project 3.1.8 Concrete structure entity testing units and personnel in water transportation engineering should meet the following conditions:
(l) The testing unit should have independent legal personality and obtain corresponding qualification level certificates; (2) The testing unit has a sound technical management and quality assurance system (3) The instruments and equipment used for testing shall have a product qualification certificate、 a valid verification (calibration) certificate from a metrological verification institution、 or a self calibration certificate (4) Testing technicians have corresponding professional and technical abilities
