3 Terms and Definitions
For the purpose of this document, the following terms and definitions apply.
3.1 Horizontal lifeline device
The device that is fixed by two or more anchors, and the horizontal angle of the
connection between any two anchors is no greater than 15°. It consists of flexible guide
rails such as steel wire rope, fiber rope, webbing, or rigid guide rails such as stainless
steel, aluminum alloy, etc.; it is used to connect and fall protection equipment and
attachments (fixed facilities such as walls, floors, and scaffolding).
NOTE: According to the different used guide rails, it is divided into flexible horizontal lifeline
device and rigid horizontal lifeline device (Figure 1).
3.2 Horizontal lifeline system
A system that consists of a horizontal lifeline device and other fall protection equipment
used in conjunction.
3.3 End anchor
A connecting fixture on a building or structure.
NOTE: It is used to connect with the end anchor of the guide rail.
3.4 End anchor connector
The part that is used to connect the guide rail to the end anchor.
3.5 Intermediate anchor
Except for the end anchor, other anchor devices that are used to fix the guide rail.
3.6 Intermediate anchor connector
The part that connects the guide rail to the intermediate anchor.
3.7 Mobile attachment device
A device that can slide along a guide rail and connect fall protection equipment.
3.8 Horizontal lifeline energy absorber
A device that is connected to a guide rail or a mobile attachment device to absorb
impact force when a fall occurs.
3.9 Maximum arrest force
During the dynamic test, the maximum impact force that is measured at the mobile
attachment device.
3.10 Maximum arrest load
During the dynamic test, the maximum impact force that is measured at the horizontal
lifeline anchor.
3.11 Minimum clearance
The minimum vertical distance that ensures the user not to collide with the highest
obstacle on the ground during the fall. It indicates the distance between the lowest
point of the test object falling and the highest obstacle on the ground.
4.1.1 The personal fall protection equipment that is connected to the horizontal lifeline
device shall meet the corresponding national standards such as GB 24543 and GB/T
23469, etc.
4.1.2 The horizontal lifeline device shall ensure that it is matched with personal fall
protection equipment and shall not accidentally disconnect after being correctly
connected.
4.1.3 If the mobile attachment device is a detachable structure, it shall undergo at least
two clear actions during disassembly.
4.1.4 If the horizontal lifeline device has a fall indication function, the fall indication shall
clearly show that the horizontal lifeline device has withstood the impact of a fall.
4.1.5 The mobile attachment device shall be able to slide smoothly on the guide rail,
and shall not cause damage to the guide rail that affects performance.
4.1.6 For the flexible horizontal lifeline device that uses fiber rope as the guide rail, the
fiber rope shall not use recycled materials and regenerated materials, and shall not
use polypropylene (polypropylene fiber) materials.
4.2 Dynamic performance
4.2.1 Horizontal lifeline device
When tested in accordance with 5.2.4, the horizontal lifeline device shall meet the
following requirements:
a) The test heavy object shall not touch the ground;
b) The horizontal lifeline device shall not be loose from the fixed structure;
c) There shall be no such phenomena, such as broken webbing, broken metal parts,
disconnected connectors, etc.;
d) The fall distance shall be no greater than the value provided by the product
provider;
e) The maximum arrest load shall not exceed the value provided by the product
provider.
4.2.2 Horizontal lifeline system
When tested in accordance with 5.2.5, the horizontal lifeline system shall meet the
following requirements:
a) The maximum arrest force shall be no greater than 6kN;
4.4 Corrosion resistance
Perform the test against the metal parts according to 5.4, the metal parts shall be no
red rust or other visible corrosion marks; but the white spots are allowed.
5 Test Methods
5.1 General
5.1.1 The test shall use an inspection instrument with an appropriate range, and the
inspection of the appearance of the components shall be carried out under good light
conditions.
5.1.2 Unless otherwise specified, a new horizontal lifeline device and test rope shall
be used for each test.
5.1.3 If the horizontal lifeline device allows multiple personal fall protection equipment
to be connected for use, the system that is composed of each type of fall protection
equipment and the horizontal lifeline device shall be tested.
5.1.4 During the inspection process, the technical requirements specified in 4.1 shall
be inspected through operation, trial-use, etc.; and if necessary, inspection shall be
carried out in accordance with the corresponding national standards; or the
manufacturer shall issue a conformity certificate for other equipment and materials.
5.2 Dynamic performance test
5.2.1 Test equipment
5.2.1.1 Dynamic test frame: It shall be able to ensure that the horizontal lifeline device
