欧盟标准 EN12641-2 商业车辆防水油布测试

swap bodies andcommercial vehicles - tarpaulins - part 2: minimumre for curtainsiders

dynamic test of acanvas segment consisting of

on the test sampledefined and illustrated in the diagram, testsare carried out with an oscillating displacement of ± 15 mm withthe following frequency

1 min. at 4hz (settlementtest for "reference zero" measurement)

2min.a4hz 

2min.a8hz.

after the testshave been carried out:

the belt must haveat least a slight residual tension, aloose belt is 
unacceptable. 

the maximumpermissible slip of the belt in tension is 5 mm at the level of thetensioner 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 acanvas segment with horizontal force consisting of

elongation test: atest with a horizontal load of 8 kn is performed on the testsample, theload is applied in the following sequence

2.5 kn for 30s (conditioningcycle, afterit we restart and tensions the canvas segment)

8 kn for 5 minutes.after doing the test

in the range of 2.5kn to 8 kn, thecalculated average stiffness of the test part must be higher than33n/mm.

there must be nochanges in position or any alteration that affects the operation ofthe components.

breaking test: inthe next test step, thesame sample must be loaded until a component failureoccurs, anda 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。
