Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 20957-8 was prepared by CEN (as EN 957-8) and was adopted, under a special “fast-track procedure”,
by Technical Committee ISO/TC 83, Sports and recreational equipment, in parallel with its approval by the
ISO member bodies.
ISO 20957 consists of the following parts, under the general title Stationary training equipment:
 Part 1: General safety requirements and test methods
 Part 2: Strength training equipment, additional specific safety requirements and test methods
 Part 4: Strength training benches, additional specific safety requirements and test methods
 Part 5: Pedal crank training equipment, additional specific safety requirements and test methods
 Part 6: Treadmills, additional specific safety requirements and test methods
 Part 7: Rowing machines, additional specific safety requirements and test methods
 Part 8: Steppers, stairclimbers and climbers — Additional specific safety requirements and test methods
 Part 9: Elliptical trainers, additional specific safety requirements and test methods

Stationary training equipment similar to a moving mechanical staircase or escalator (see figure 2)
NOTE Work is carried out by simulating climbing a conventional staircase.
3.3
Climber
stationary training equipment that is equipped with feet and hand positions that can be moved in a reciprocating
motion (see figure 3)
3.4
dependent action
movement of each foot pedal linked directly or indirectly
