标题: ASTM F963-08 的轮胎玩具测试方法疑问
ASTM F963 08 对於轮胎玩具的测试方法如下:

8.7.3 Tumble Test for Wheeled Toys
... The toy, including accessories, where applicable, shall be caused to fall down the steps two times in each of four attitudes: tumbling forwardly end-over-end and tumbling rewardly end-over-end from each...

我的理解是, 把玩具从楼梯 (见 ASTM Fig 26) 推下, 玩具前後左右四个方向, 每个方向分别以 Tumbling forwardly 及 Timbling rearwardly 各一次, 总共推八次.

请问怎麽推才是 Tumbling forwardly 及 Timbling rearwardly?
