Interface between test object and test environment Clause Samples

Interface between test object and test environment. Figure 4 and Figure 5 show the physical interfaces between the SOC cell / SOC stack test object and the test environment. The physical interfaces between the test environment (test station) and the SOC cell/stack test object can be separated in media, electric, heat and mechanic interfaces. Media interfaces are the reactants inlet and outlet; electric interfaces are the load and power supply and voltage wiring; heat interface is the oven and the mechanic interface is to mount the cell/stack on the test station which may supply compression force to the cell/stack. These interfaces will be defined by different physical parameters. Depending on the test program these physical parameters can be either of input nature (TIP) or of output nature (TOP) (see Table 1). Test environment TTP A Test Object: Cell V TBP negative electrode gas out VCell TOven Test environment Test object: SOC Stack V V A V V negative electrode gas out TBP TTP TOven For the reactants at cell/stack inlet and/or outlet these parameters are:  Temperature,T  Flow (mass or volume),f  Pressure,p  Gas composition,x The electric interface parameters are:  Cell/stack current (common synonym is stack load), I  Stack voltage, Vstack  Voltages of cell or the individual repeating units, Vcell or VRU,i The heat interface parameters are:  Oven temperature, Toven  Stack top plate temperature, TTP  Stack bottom plate temperature, TBP  Cell or stack internal temperature Tcell or Tstack,intern Considering the fact that a temperature gradient in the stack is unavoidable and depends on various factors such as gas flow rates, current, thermal exchange rate with the furnace, it is difficult to determine the stack temperature. In practice, depending on the stack design, temperature sensors mounted at different locations in or around the stack (e.g., in endplates, in gas inlet/outlet channels, or just in close proximity to the stack) can be used to estimate the stack temperature. It is however important to identify the one that represents the best the real stack temperature. In order to make results comparable among different test facilities, it is necessary to agree prior to the test on which temperature is used to represent the stack temperature. For the results presentation, it is recommended to show also other temperatures measured in order to obtain information on the temperature distribution in the stack. The mechanic interface parameter is:  Cell or stack compression force, Fcompr Ideally, the p...

  • Random Testing Notwithstanding any provisions of the Collective Agreement or any special agreements appended thereto, section 4.6 of the Canadian Model will not be applied by agreement. If applied to a worker dispatched by the Union, it will be applied or deemed to be applied unilaterally by the Employer. The Union retains the right to grieve the legality of any imposition of random testing in accordance with the Grievance Procedure set out in this Collective Agreement.

  • Substance Abuse Testing The Parties agree that it is in the best interest of all concerned to promote a safe working environment. The Union has no objection to pre-employment substance abuse testing when required by the Employer and further, the Union has no objection to voluntary substance abuse testing to qualify for employment on projects when required by a project owner. The cost and scheduling of such testing shall be paid for and arranged by the Employer. The Union agrees to reimburse the Employer for any failed pre-access Alcohol and Drug test costs.

  • Performance Testing (a) All performance tests of the Project, including any Initial Performance Test required in Section 2 of Appendix VIII, will be performed in accordance with the test procedures set forth in Appendix VIII (“Performance Test”), including additional procedures and protocols related to Performance Testing as mutually agreed between Buyer and Seller (“Test Procedures”). Seller shall bear all costs and receive all revenues, if applicable, associated with all Performance Tests. (b) After the Initial Delivery Date and during the Delivery Term, Buyer will have the right to conduct a Performance Test (“Buyer Performance Test”) no more than once a calendar year to demonstrate whether the Project is capable of delivering the Distribution Services at the Contract Capacity. Within 30 calendar days following a Buyer Performance Test, Seller will have the right to retest the Project with a Performance Test (“Seller Retest”). For the avoidance of doubt, the results of any Seller Retest will supersede the results of the preceding Buyer Performance Test. (i) If a Buyer Performance Test or, if a corresponding Seller Retest has occurred, a Seller Retest demonstrates the Project is capable of delivering Distribution Services at or above ninety-nine percent (99%) of the Initial Contract Capacity, the Contract Capacity will remain the Initial Contract Capacity; (ii) If a Buyer Performance Test or, if a corresponding Seller Retest has occurred, a Seller Retest demonstrates the Project is capable of delivering Distribution Services at more than or equal to eighty-five (85%) of the Initial Contract Capacity, but less than ninety-nine percent (99%) of the Initial Contract Capacity (“Testing Band”), the Contract Capacity will be automatically adjusted (upwards or downwards) to the capacity commensurate with the amount of Distribution Services the Project delivered during the Performance Test within the Testing Band. (iii) If a Buyer Performance Test or, if a corresponding Seller Retest has occurred, a Seller Retest demonstrates the Project is not capable of delivering Distribution Services of at least eighty-five percent (85%) of the Initial Contract Capacity, an Event of Default shall occur in accordance with Section 7.1(a)(viii).

  • Meter Testing Company shall provide at least twenty-four (24) hours' notice to Seller prior to any test it may perform on the revenue meters or metering equipment. Seller shall have the right to have a representative present during each such test. Seller may request, and Company shall perform, if requested, tests in addition to the every fifth-year test and Seller shall pay the cost of such tests. Company may, in its sole discretion, perform tests in addition to the fifth year test and Company shall pay the cost of such tests. If any of the revenue meters or metering equipment is found to be inaccurate at any time, as determined by testing in accordance with this Section 10.2 (Meter Testing), Company shall promptly cause such equipment to be made accurate, and the period of inaccuracy, as well as an estimate for correct meter readings, shall be determined in accordance with Section 10.3 (Corrections).
