Performance tests after Completion. a. The Contractor applies formally for each test/test phases to start. The test only starts when the Plant is in a fully operational state. Plant commissioning and optimization are not be allowed during testing. b. The Contractor submits, for approval by the Project Manager, a complete and detailed test procedure prior to any tests commencing. This test procedure includes all tests and inspections required in terms of the respective specifications and other tests and inspections deemed necessary by the Contractor to prove to the Project Manager’s satisfaction that the Plant is performing according to this specification and shall include reliability - and capacity tests. c. Reliability tests constitute at least one month of continuous unassisted operation of the Plant of which the last week are completely trouble free. The reliability tests are regarded as successful when the stoppages as a result of this relevant system is limited to a maximum of 0.5 incidents per day and that the downtime as result of the combined stoppages is less than 30 minutes per day on average measured over the period of 30 days continuous operation in the fully automatic mode with no control simulations in place. d. During capacity testing the system operates at maximum design capacity for a continuous period of more than 8 hrs. The Plant operates satisfactorily with no indication of constraints in the functional performance for extended operation at this maximum load. e. The following are tested and confirmed, as a minimum: Confirmation that the control system performs according to the design with reference to control and sequence starting and stopping and that all protection devices, limits and the communication links operates correctly. No spillages No blockages or build ups that may result in blockages Acceptable levels of dust in the environment. The levels of dust complies with statutory requirements and no nuisance dust in the general working areas for operators and maintainers are present. The central loading of conveyors The performance of the transfer chutes. The evaluation of conveyor transfer balance when tripped at full capacity and speed (no over spilling at transfer points during conveyor run-down). The ability of the Plant to stop and start under full load. All the functional operation of the machines under load. Performance of the conveyor drive train with reference to acceleration torque introduction, the dynamic behaviour and the suitability of the design with reference to the system resistance. In case of failure of any of the test phases, the functional tests for the relevant Plant area and all other effected Plant are repeated. The capacity and reliability test are re-done in total on the relevant system. During the tests period, the Employer’s Personnel operates the Plant, under the supervision of the Contractor. The Contractor is not allowed to operate the Plant directly. The nominal as well as average capacities are proven during this period. f. The Project Manager reserves the right to carry out further tests on the installation. On completion of the tests the Contractor supplies complete test certificates as necessary, and such prescribed statutory documents as are required certifying that the equipment is in complete working order and that all working parts are effectively lubricated.
