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. Annex 6 - Appendix 4
Vehicle Safety Vehicles used by employees, whether or not issued to the employee, shall be maintained in safe operating condition by the state.
ODUF Testing 6.6.1 Upon request from TWTC, AT&T shall send ODUF test files to TWTC. The Parties agree to review and discuss the ODUF file content and/or format. For testing of usage results, AT&T shall request that TWTC set up a production (live) file. The live test may consist of TWTC’s employees making test calls for the types of services TWTC requests on ODUF. These test calls are logged by TWTC, and the logs are provided to AT&T. These logs will be used to verify the files. Testing will be completed within thirty (30) days from the date on which the initial test file was sent.
