a) in the scope, energy absorbing systems (EAS) according to this document have been limited to users
weighing not less than 40 kg (total weight without equipment) and no more than 120 kg (total weight
including the equipment) and the use is limited on via ferrata according to EN 16869:2017;
b) modification of the maximum impact force in 4.2.3 a);
c) modification of the mass in 4.2.3 b);
d) modification of the test apparatus and the test method for the dynamic performance;
e) the manufacturer’s instructions and information take into account the previous modifications, the
