- What changed
- During the application of the load, the loading device may now deviate by not more than 5° in z-direction, in each direction. The reference is the parallel plane to the x-y plane of the chassis.
- Why
- The proposal introduces a tolerance for the position of the loading device during the test.
Q1What changed1 change
Tolerance for the position of the loading device (Annex 3, para. 7.4.4.1.)
During the test, the loading device must be parallel to the x-y plane of the chassis (paragraphs 7.4.4. and 7.4.4.1.). Paragraph 7.4.4.1. now adds a tolerance for the position of the loading device. During the application of the load, the loading device may deviate by not more than 5° in z-direction. This applies from the parallel plane to the x-y plane of the chassis, in each direction.
