Swap bodies and commercial vehicles - Tarpaulins - Part 2: Minimum re for curtainsiders

Dynamic test of a canvas segment consisting of

On the test sample defined and illustrated in the diagram, tests are carried out with an oscillating displacement of ± 15 mm with the following frequency

1 min. at 4 Hz (Settlement test for "reference zero" measurement)

2min.a4Hz 

2min.a8Hz.

After the tests have been carried out:

The belt must have at least a slight residual tension, a loose belt is 
unacceptable. 

The maximum permissible slip of the belt in tension is 5 mm at the level of the tensioner lock. 

动态测试所需的样品：

带钩和杠杆偏转点之间的长度应不超过 350 毫米。 （此要求对于没有带子操作的张紧器是不必要的）

Static test of a canvas segment with horizontal force consisting of

Elongation test: A test with a horizontal load of 8 kN is performed on the test sample, the load is applied in the following sequence

2.5 kN for 30 s (conditioning cycle, after it we restart and tensions the canvas segment)

8 kN for 5 minutes. After doing the test

In the range of 2.5 kN to 8 kN, the calculated average stiffness of the test part must be higher than 33N/mm.

There must be no changes in position or any alteration that affects the operation of the components.

Breaking test: In the next test step, the same sample must be loaded until a component failure occurs, and a diagram on the force-displacement must be recorded

静态测试所需的样品

帆布必须配备上下加强件。 中央部分的水平加强件可以省略。

• 水平和垂直带的排列间隔≤600 mm。垂直带的总数 X 必须至少相等

• 如果有抓点，则垂直带在抓点边缘的距离必须≤ 100 mm。

释放，其行为必须清晰明显）

释放手动杆，必须首先通过激活单独的解• 带钩的垂直耦合深度必须至少为 22.5 毫米。

• 垂直肩带：抗拉强度 ≥ 23 kN

• 帆布面料：必须证明表中所示要求的合理性
