Fall protection safety rope range
-
This standard specifies the classification and marking of safety ropes, technical requirements, test methods, inspection rules and markings.
This standard applies to safety ropes used in high-altitude operations, ascent and suspension operations of personnel with a weight and a weight of not more than 100 kg.
This standard does not apply to safety ropes for sports, fire fighting and other purposes. -

Terms and Definitions
The terms and definitions established by GB/T 12903 and set forth below apply to this Standard.
Safety rope lanyard
A rope (belt, wire rope, etc.) that connects the tie to the hanging point in
the seat belt.
Note: Safety ropes are generally used in conjunction with buffers to expand or
limit the wearer’s range of motion and mitigate impact energy.
3.2 Adjustable safety cord adjustable lanyard Safety ropes with adjustable
length.
3.3 Safety ropes for pole work lanyard for work positioning systems Safety
ropes in harnesses for rod work.
3.4 Zone restrictions are restricted with safety ropes lanyard for restraint
systems Safety ropes are included in zone restricted seat belts.
3.5 Fall suspension with safety ropes lanyard for fall arrest systems Safety
ropes in the drop suspension harness.
3.6 End ring eye terminations
At the end of the safety rope, the ring or set is formed by folding,
stitching, weaving, etc.
Note: The end ring eye can be loaded with metal parts or directly for hanging.
GB 24543-2009
c) Install the safety rope on the static mechanical properties test device,
apply a load of 6kN, and maintain it for 3min;
d) Measure the slip off the mark after unloading.
6.3 Static mechanical properties test
The test steps are as follows:
a) Install the safety rope on the static mechanical properties test device and
load according to Table 1, loading speed: webbing and fiber rope safety rope
Should not exceed 100mm/min, wire rope and chain safety rope should not exceed
30mm/min;
b) Hold for 3 min after reaching the load, unload, observe and record the
damage of the safety rope.
6.4 Dynamic mechanical properties test (adjustable safety rope for falling
suspension)
The test steps are as follows:
a) Adjust the position of the adjustment buckle so that the length of the
safety rope is (2000±25) mm; If the length is not enough, adjust to the
maximum length;
b) Connect one end of the safety rope to the test weight through the
connector, and the other end to the rigid hanging point of the test stand, and
the connector should match GB/T 23469;
c) Lift the test weight so that the horizontal distance from the hanging point
to the release point before release is not more than 300mm, and the free
falling distance of the test weight at least (4000±100) mm; If the length of
the adjustable safety rope is not enough, the free falling distance of the
test weight cannot be reached (4 000±100) mm, the test weight is lifted to the
maximum height;
d) Release the test weight, observe and record the damage of the adjustable
safety rope after the heavy object is stationary.
6.5 Corrosion resistance test
According to the neutral salt spray (NSS) test method specified in GB/T 10125,
the test cycle is 2d.
Inspection rules
7.1 Inspection Categories
Inspection categories are divided into factory inspection and type inspection.
7.2 Factory Inspection
The production enterprise shall carry out factory inspection of the batch of
the products produced batch by batch, and the inspection items and single
inspection sample size, unqualified classification and judgment shall be
carried out See Table 2 for definite arrays.

7.3 Type inspection
7.3.1 Type inspection shall be carried out in the following cases:
a) Identification of new products or trial identification of old products for
the production of factories;
b) After formal production, when the raw materials, production processes,
product structure and form of the product change greatly, which may affect the
performance of the product;
c) when production resumes after more than half a year of suspension of
production;
d) periodic inspection, once a year;
e) When there is a big difference between the factory inspection results and
the last type inspection results;
f) When the relevant competent department of the state puts forward the type
inspection requirements.
GB 24543-2009
7.3.2 The sample shall be randomly selected by the unit proposing the
inspection or entrusted to a third party from the products that have passed
the factory inspection of the enterprise, and the number of samples shall be
satisfied
All test items are required as principles,
