Standard EN 517
Roof safety hooks

This standard applies to roof safety hooks situated on the surface of pitched roofs. They are intended for:

• the attachment of ladders, for supporting working platforms
• as anchorage points to which personal protective equipment against falls or for restraint are attached, such as singer-user, CE certified inertia reel blocks, energy absorbers, fall arrest devices on ropes, not producing a force greater than 600 kg

The standard specifies:

• the hook’s size and height
• the appropriate materials and surface treatment
• requirements for safety hooks fastened to the roof construction, including their fastening system
• test requirements (static and dynamic loads)
• use and marking requirements

An updated draft of this standard defines 2 types of hooks:

• type A: Roof safety hooks designed only to accept tensile forces in the direction of the slope of the roof
• type B: Roof safety hooks designed to accept tensile forces in the opposite direction of the slope of the roof, as well as in the lateral directions.

Test requirements:

• deformation should be measured under the test load of 1.5 kN and should not deflect more than 5 mm in direction of the force
• functioning of the hook and its fastening shall not be impaired below 2.6 kN
• hook should withstand a single static load at the anchorage point of 1 ton (draft version of the standard)
• hook should withstand a dynamic load at the anchorage point of 100 kg falling from 2.50 m

Standard EN 13374
Temporary edge protection systems

This standard applies to temporary edge protection systems used in construction, whose main function is to prevent people or objects from falling from roofs, beams, girder, stairs and other areas requiring the installation of protective equipment.

By extension, it also concerns scaffolding consoles fitted with guardrails whose main function is to prevent people or objects from falling from roofs.

The standard specifies:

• the size and height of railings:
  • Class A: the space between two rails must be less than 47 cm
  • Class B: the space between two rails must be less than 25 cm
  • Class C: a safety net with mesh size less than or equal to 10 cm x 10 cm
• test requirements (static and dynamic loads)
• use and marking requirements

The standard defines 3 classes depending on roof pitch:

• Class A: slope less than 10° /2.12:12.
• Class B: slope less than 30° /6.93:12 (or 60° /20.78:12 if the drop height is less than 2 m).
• Class C: slope less than 45° /12:12) (or 60° /20.78:12 if the drop height is less than 5 m)

Test requirements:

• Class A:
  – 125 kg load in a vertical direction
  – 30 kg load in an outwards direction
  – 20 kg in a lateral direction

• Class B:
  – 50 kg bag falling from 2.25 m and producing a shock at the bottom of the post
  – 50 kg bag falling from 1 m and producing a shock at the top of the post

• Class C:
  – 75 kg roll falling from 5 m along a 60° /20.78:12 slope
