BS EN 957-5:2009 pdf free download – Stationary training equipment Part 5: Stationary exercise bicycles and upper body crank training equipment, additional specific safety requirements and test methods.
6.1 General
6.1.1 Dimensional check
6.1.2 Visual examination
6.1.3 Tactile examination
6.1.4 Performance test
6.1.5 Manufacturer’s certificate
6.2 Testing of temperature rise
Apparatus: contact thermometer with an accuracy of ± I °C.
Pedal the training equipment at (200 ± 10) W with (60 ± 1) rpm for 3 periods of (20 ± 1) mm.
After each 20 mm period, rest for (5 ± 1) mm.
See also EN ISO 13732-1.
6.3 Testing of transmission elements and rotating parts
6.3.1 Crank and protective cover finger probe examination
Insert the test finger probe according to EN 957-1:2005, Figure 1, parallel to the axis of rotation with a tolerance of ± 5°, in contact with the crank and the protective cover. The test shall be carried out in the most onerous position with the crank rotated fully in both directions. Determine whether the test finger becomes entrapped. If the angle allows the test finger to be pushed away it is not considered to be an entrapment.
If the protective cover is smaller than the rotated diameter of the crank at any point perform the dimensional test.
6.3.2 Other moving parts finger probe examination
Approach a test finger probe B in accordance with EN 71-1 from all sides to all moving parts for class H and EN 957-1:2005 for class S and I.
Determine whether the test finger is trapped or whether it touches moving parts which are not smooth.
6.4 Testing of intrinsic loading
The training equipment shall be free standing on a flat surface. Clamp the seat pillar in its most onerous position as specified in the manufacturer’s instructions for use.
Plot the position of the seat pillar compare to the seat tube.
Apply on the seat, with a (300 ± 5) mm x (300 ± 5) mm plate a pre load of 10 % of the test load as described in 5.3 for 1 mm and measure the distance between the highest rigid part of the seat and the floor. Then apply the test load for 3 mm. After the release of the test load, measure again height in the same position as before versus the floor whilst under pre load, and calculate the permanent deformation.
Check that the requirements specified in 5.3 are fulfilled.
For other types of crank training equipment, e.g. recumbent, other relevant dimensions shall be used.
6.5 Testing of seat tilting
Fix the seat and the seat pillar to the seat tubes as specified in the instructions.
Apply a vertical force of (650 ± 32,5)N at (25 ± 5) mm from either the front or rear of the saddle on an area of 100 mm2.
Arrange the test rig in such a way that the maximum torque is applied to the saddle clamp. The duration of the test shall be (5 ± 1) mm.
6.6 Testing of handlebars
Fix the machine to prevent tilting and/or slipping.
