Test The outer surface of the lamp lenses shall be subjected once or more than once to the action of the sand jet produced as described above. The jet shall be sprayed almost perpendicular to the surface to be tested. The deterioration shall be checked by means of one or more samples of glass placed as a reference near the lenses to be tested. The mixture shall be sprayed until the variation in the diffusion of light on the sample or samples measured by the method described in Appendix 2, is such that: Δ d = (T5 - T4) / T2 ≤ 0.0250 ± 0.0025 Several reference samples may be used to check that the whole surface to be tested has deteriorated homogeneously.
Test conditions 6.1.1. The test shall be performed on a flat, dry concrete or asphalt surface affording good adhesion. 6.1.2. The ambient temperature shall be between 0°C and 45°C. 6.1.3. The horizontal visibility range shall allow the target to be observed throughout the test.
Performance Tests Contractor shall perform Performance Tests in accordance with Section 11.2 of the Agreement and Attachment S.
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).
Hearing Tests Audiometric tests should be conducted within two months of a person commencing employment, and thereafter at intervals of two years.
