Reliability figures of existing equipment shall be supported by evidence from operational experience at similar types of installation / figure given by OEM.
System availability tests shall be conducted after completion of the field tests. The system availability test shall apply to the RT-DAS system (hardware and software) integrated with its FRTU and R-APDRP IT SYSTEM . However, the non-availability of FRTU /R-APDRP –IT system etc & Communication System shall not be considered for calculating system availability. However , FRTU, , Auxiliary power supply shall be tested as per the provisions given in their chapters.
The RT-DAS system (hardware and software systems) shall be available for 99.5% of the time during the 120 hours (5 days) test period. However, there shall not be any outage /down time during last 48 Hours of the test duration.

Availability tests of FRTUs shall be conducted along with System availability test for 120 hours. Each FRTUs shall exhibit minimum availability of 98%. In case the FRTU availability falls short of 98%, the contractor shall be allowed to repeat the FRTU availability test (for failed FRTU only) after fixing the problem, failing which the equipment shall be upgraded by the contractor to meet the availability criteria without any additional cost implication to the owner.
In the event of unsuccessful reruns of the availability test, employer may invoke the default provisions described in the General Conditions of Contract.
The RT-DAS system shall be considered as available if

The downtime shall be measured from the instant, the contractor starts the investigation into the system and shall continue till the problem is fixed. In the event of multiple failures, the total elapsed time for repair of all problems (regardless of the number of maintenance personnel available) shall be counted as downtime. Contractor shall be allowed to use mandatory spares (on replenishment basis) during commissioning & availability test period. However it is the contractor’s responsibility to maintain any additional spares as may be required to maintain the required system availability individual device/ equipment availability. All outage time will first be counted but if it is proven to be caused by hardware or software not of Contractor’s scope, it will then be deducted.
8.4.2 Hold time
During the availability test, certain contingencies may occur that are beyond the control of either employer or the Contractor. These contingencies may prevent successful operation of the system, but are not necessarily valid for the purpose of measuring RT-DAS availability. Such periods of unsuccessful operation may be declared "holdtime" by mutual agreement of employer and the Contractor. Specific instances of holdtime contingencies could be Scheduled shutdown of an equipment, Power failure to the equipment, Communication link failure.
