1、Test purpose

The purpose is to test the limit dynamic performance of ASAT horizontal lifeline in condition 

that multi-persons are attached at a single span, so as to determine the limit bearing capacity 

of a single-span of the lifeline in practical application.

2、Lifeline configuration

are vertically arranged one above the other; its ends are fitted with P type end fittings; and 

the lifeline is properly tensioned. 

3、Test basis

3.1  The measurement taken according to the standard shows that the impact peak of 12 kN 

can be reached by the combination of 1 m dynamic rope and 200 kg weight. Therefore, it is 

determined to release 200 kg weight at 1.5 m height to create the impact peak of 13 kN (the 

value is higher than 12 kN required in the standard) for the test.

3.2  The measurement taken according to the standard shows that the impact peak of 9 kN 

can be reached by the combination of 2 m dynamic rope and 100 kg weight. Therefore, it is 

determined to release 100 kg weight at 2.5 m height to create the impact peak of 9 kN for the 

test.

4、Test procedure

4.1  Attach 200 kg weight to the slider on the lifeline and its releasing height is specified in 3.1.  

Position the slider in the middle of the lifeline and then release the weight.

4.2  The 200 kg weight still remains hanging on the lifeline after the releasement. Attach a 100 kg 

weight to the slider on the lifeline and its releasing height is specified in 3.2. A force measurement

apparatus is linked between the slider and the dynamic rope. Release the weight. 

4.3  The above mentioned 200+100 kg weights still remain hanging on the lifeline. Attach another 

100 kg weight to the slider on the lifeline and its releasing height is specified in 3.2. Release the 

weight.

4.4  After the dynamic test, carry out the static strength test according to the standard requirements.

5、Test data

5.1 After the 200 kg weight is released, the slider on the lifeline is measured to move down about 

1.1 m, which is consistent with the drooping height of the lifeline as expected. The shock absorbing 

rings slip to the positions near the stop rings at both ends. No visible deformation nor break is found 

on all the parts of the system.

5.2  After the first 100kg weight is released, the measured impact peak is 8.59 kN. No newly visible

deformation nor break is found on the lifeline, and the drooping height of the lifeline measured 

remains unchanged.

5.3  After another 100kg weight is released, no newly visible deformation nor break is found on the 

lifeline, and the drooping height of the lifeline measured remains unchanged.
