EN 358:2018 (E)
Introduction

When work undertaken at a height is of short duration, or for technical reasons, the provision of a

working platform, suitable barriers and other similar safeguards is impracticable, then the prevention

from falling from a height while performing correctly the related work activity can be achieved by the

use of personal fall protection equipment. Equipment when manufactured in accordance with this

European Standard is intended either to prevent the user from reaching a position where a fall can

occur (restraint) or to secure the user safely in position at the point of work in such a way that the user

can share and control his weight between the waist and the feet (work positioning). It is essential to

note that such personal fall protection equipment by design does not meet the requirements necessary

for the purposes of fall arrest. It may be necessary to supplement it with collective or personal means of

protection against falls from a height. Its safe use, in practice, relies upon the effective training and

instruction of the user.

Work positioning belts or restraint belts are not suitable if there is a risk of uncontrolled slippage by the

user, e.g. when working on a steep roof or wet or slippery surfaces, which could result in the user being

suspended by or exposed to unintended tension by the belt.

push with a load of ( 200 ) N by using a hand-held load cell making sure that the buckle does not

−10

move sideways. Check that the fastening element holds the mass. After unloading, remove the test mass

and check if the button goes back in its original position. If it does not go back in its original position,

turn the buckle, reattach the test mass on the same end of the belt and push the other button with the

same procedure. Check that the fastening element holds the mass.
Repeat the test by pushing the other button first.
Repeat the tests by using test masses of (5 ± 0,1) kg and (10 ± 0,1) kg.
