Road test surface Clause Samples
The 'Road test surface' clause defines the standards and requirements for the condition and quality of the surface used for road testing vehicles or equipment. It typically specifies the type of materials, smoothness, and maintenance levels necessary to ensure consistent and reliable test results. For example, it may require that the surface be free of debris, potholes, or irregularities that could affect test outcomes. The core function of this clause is to ensure that road tests are conducted under controlled and repeatable conditions, thereby improving the accuracy and safety of the testing process.
