Introduction

This part of this European Standard concerns the safety of strength training equipment.

It amends and supplements EN 957-1. The requirements of this specific standard take priority over those in the

general standard.
1 Scope

This part of this European Standard specifies additional safety requirements for strength training equipment in

addition to the general safety requirements of EN 957-1.

This part of this European Standard is applicable to stationary training equipment type strength training equipment

with stack weight resistance or other means of resistance like weight disks, elastic cords, hydraulic, pneumatic and

magnetic systems and springs (type 2) (hereinafter referred to as training equipment) with the classes S and H.

Any attachment provided with the training equipment for the performance of additional exercises are subject to the

requirements of EN 957-1.
2 Normative references

This European Standard incorporates by dated or undated reference, provisions from other publications. These

normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For

dated references, subsequent amendments to or revisions of any of these publications apply to this European

Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the

publication referred to applies (including amendments).

EN 294, Safety of machinery - Safety distance to prevent danger zones being reached by the upper limbs.

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.

---------------------- Page: 5 ----------------------
EN 957-2:2003 (E)
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)
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);
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)
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);
1,5 is the dynamic coefficient;
2 is the safety coefficient.
