test fixtureの説明

The test fixture is defined as a device used to simulate obstacles that may be encountered on an airport ramp (e.g., wheel chocks, storm drains, fuel pit lids, snow and ice ruts, etc.). The test fixture shall be made out of wood measuring 10.2 cm (4 inches) high x 15.2 cm (6 inches) wide x 60.96 cm (24 inches) long. The top comers shall be symmetrically cut at 45-degree angles along the longitudinal length of the member providing a top flat surface measuring 5.1 cm (2 inches) in width. The test fixture shall be secured in such a manner that prevents sliding or overturning as the vehicle is driven over it during dynamic load testing.
