3. If the supplier (including transportation) causes any damage, defect, shortage or does not conform to the quality standards and specifications specified in the contract in the field inspection, the bidder shall have the right to refuse to accept, and all expenses shall be borne by the supplier.
4. The tenderer shall also submit complete inspection methods and acceptance standards (including single equipment and complete system). As the basis for accepting the tenderee.
4. Guide installation and commissioning
1. After the installation is completed, the tenderer is obliged to cooperate with the mechanical and electrical installation unit to conduct a comprehensive inspection and test on the system, and complete the partial and comprehensive commissioning of the system.
2. All testing must be carried out by an engineer certified by the product manufacturer. Instruments meeting the corresponding accuracy requirements shall be used in the test. The supplier is responsible for the instruments, tools and materials required for the test work.
5. Commissioning
1. The electromechanical device unit is responsible for the trial operation process of the whole system;
2. Test run is an important link to evaluate the quality and reliability of the whole system engineering. The probation period is three months. When the main indicators (monitoring performance, reliability and stability) meet the requirements of test operation acceptance, final acceptance can be carried out. If the above-mentioned conditions are not met, a new trial run for three months is required;
3. The tenderer must submit operation and maintenance manual to make the tenderer familiar with the pre installed equipment and system. The manual shall include control procedures, operation and maintenance procedures. Each manual shall include at least the following information:
A. All equipment specifications and detailed Chinese operation manual, commissioning manual and quality assurance 4 sets;
B. Describe common faults of system and main components, including accessories and assembly drawings, general accident description. The manual shall include an operation manual and a list of general spare parts;
