EN 957-1:1996, Stationary training equipment — Part 1: General safety requirements and test methods.
3 Terms and definitions
For the purposes of this European Standard the terms and definitions given in EN 957-1:1996 apply.
4 Classification
Clause 4 of EN 957-1:1996 applies.
5 Safety requirements
5.1 General
Depending on the design of the piece of training equipment the following requirements shall apply as appropriate.
5.2 Loading
5.2.1 Intrinsic loading
Each piece of equipment loaded with the user's bodymass shall withstand a force F
for class H 2,5 times the bodymass (100 kg) without breakage,
for class S 2 times the bodymass (100 kg) without permanent deformation.
When tested according to 6.2, supports (e. g. load bearing surfaces) shall not be deformed by more than f = 1/100,
cantilever supports (cantilever surfaces) by more than f = 1/150 and other dimensions by more than 1 %. The
training equipment shall not break when a static load of 4 times the bodymass is applied.
5.2.2 Extrinsic loading
5.2.2.1 Class H
When tested according to 6.3 and loaded with the user's bodymass and/or reaction forces or moments of the user,
each piece of equipment shall withstand without breakage a load F according to equation (1):
F(N) = [G (kg) + 1,5 G (kg)] · 2,5 · 9,81m/s² (1)
k
where
G is the maximum load in kilograms indicated by the manufacturer (see clause 10 of EN 957-1:1996);
G is the force in kilograms determined by the proportional bodymass (100 kg);
k
1,5 is the dynamic coefficient;
2,5 is the safety coefficient.
5.2.2.2 Class S
When tested according to 6.3 and loaded with the user's bodymass and/or reaction forces or moments of the user,
each piece of equipment shall withstand a load F according to equation (2):
F (N) = [G (kg) + 1,5 G (kg)] · 2 · 9,81m/s² (2)
k
where
G is the maximum load in kilograms indicated by the manufacturer (see clause 10 of EN 957-1996). The
torques as specified in Table 1 are to be taken as basis for the calculation of G, if greater than the
manufacturer's stated maximum load;
G is the force in kilograms determined by the proportional bodymass (100 kg);
k
1,5 is the dynamic coefficient;
2 is the safety coefficient.
