Annex ZA
(informative)
Relationship between this European Standard and the safety requirements
of Directive 2001/95/EC aimed to be covered
This European Standard has been prepared under a Commission’s standardization request
Standardisation mandate issued to the European standardisation organisations (ESOs) to develop
European standards for stationary training equipment “M/506” to provide one voluntary means of
conforming to the safety requirements of Commission Decision (EU) No 476/2011 of 27 July 2011
implementing General Product Safety Directive 2001/95/EC of the European Parliament and of the
Council with regard to safety requirements for stationary training equipment.
Once this standard is cited in the Official Journal of the European Union under that Directive
2001/95/EC, compliance with the normative clauses of this standard given in Table ZA.1 confers,
within the limits of the scope of this standard, a presumption of conformity with the corresponding
safety requirements of that Directive and associated EFTA regulations.

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.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 83, Sports and other recreational facilities and
equipment, in collaboration with the European Committee for Standardization (CEN) Technical Committee
CEN/TC 136, Sports, playground and other recreational facilities and equipment, in accordance with the
Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This third edition cancels and replaces the second edition (ISO 20957-2:2020), which has been technically
revised.
The main changes are as follows:
— referenced standards have been updated with year of publication;
— NOTE 2 has been added to Clause 1;
— Clause 3 has been updated to add definition and corresponding figure for rack station;
— Clause 5 has been restructured;
— 6.1.5 “Finger entrapment test” has been added.
