集装袋厂家:集装袋吊带、吊绳测试方法

Test method for sling and rope of container bag

1、取样方法 在集装袋吊环处截取适当长度的吊带试样,吊带试样至少为两块。

1. The sampling method is to cut the sling sample of appropriate length at the lifting ring of the container bag, and the sling sample shall be at least two pieces.

2、伸长试验 将试样装在抗拉试验机上,施加196N的涨紧负荷后,划出200mm间距的标线,100mm/min的速度拉伸,当负荷达到抗拉强度F的30%时,测出标线的间距。

2. In the elongation test, install the sample on the tensile testing machine, apply 196N tension load, draw a line with a spacing of 200mm, stretch at a speed of 100mm / min, and measure the distance between the lines when the load reaches 30% of the tensile strength F.

伸长率(%)=L×100 200 L表示负荷达到抗拉强度30%的标线间距。

Elongation (%) = l × 100 200 L indicates the distance between markings when the load reaches 30% of the tensile strength.

3、抗拉强度试验 将试样装在夹具间距为220mm的抗拉试验机的夹具上,以约100mm/min的速度拉伸,测出断裂时的抗拉强度。
