Test parameter variation Sample Clauses
The 'Test parameter variation' clause defines the process and conditions under which the parameters of a test may be adjusted during the course of a project or agreement. This clause typically outlines who has the authority to request or approve changes to test parameters, the procedures for documenting such changes, and any limitations or notification requirements. For example, it may allow for the modification of temperature, pressure, or timing settings in a laboratory test if initial results are inconclusive. The core function of this clause is to provide flexibility in testing while maintaining clear communication and control, thereby ensuring that tests remain relevant and effective without compromising the integrity of the results.
Test parameter variation. The manufacturer shall declare the system boundaries to the Technical Service. The Technical Service shall define different combinations of test parameters (e.g. present speed of the ALKS vehicle, type and offset of target, curvature of lane) in order to cover scenarios in which a collision shall be avoided by the system as well as those in which a collision is not expected to be avoided, where applicable. If this is deemed justified, the Technical Service may test additionally any other combination of parameters. If a collision cannot be avoided for some test parameters, the manufacturer shall demonstrate either by documentation or, if possible, by verification/testing that the system doesn’t unreasonably switch its control strategy.
Test parameter variation. 3.1.6.1. The manufacturer shall declare the system boundaries to the Type Approval Authority. The Type Approval Authority shall define different combinations of test parameters (e.g., present speed of the vehicle under test, type and offset of the target, curvature of lane).
3.1.6.2. In order to confirm consistency of the system, base tests shall be carried out at least 2 times. If one of the two test runs fails to meet the required performance, the test shall be repeated once. A test shall be accounted as passed if the required performance is met in two test runs and the manufacturer has provided sufficient evidence according to Annex 3 Appendix 4. The Type Approval Authority may choose to require additional test runs to confirm the declaration thresholds outlined in Annex 3 Appendix 4.
3.1.6.3. When conditions deviate from those specified for the base test, the system shall not unreasonably switch its control strategy. This shall be verified by the extended testing. Each parameter as outlined in the extended tests shall be varied, where variations can be grouped into a single test design. In addition, the Type Approval Authority may request additional documentation evidencing the system’s performance under parameter variations not tested.
