Annex ZA
(informative)
Relationship between this European Standard and the essential
requirements of Directive 2006/42/EC, aimed to be covered
This European Standard has been prepared under a Commission’s standardization request “M/396
Mandate to CEN and CENELEC for Standardisation in the field of machinery” to provide one voluntary
means of conforming to essential requirements of Directive 2006/42/EC of the European Parliament

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 documents 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).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions 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

This document was prepared by Technical Committee ISO/TC 72, Textile machinery and accessories,
Subcommittee SC 8, Safety requirements for textile machinery, in collaboration with the European
Committee for Standardization (CEN) Technical Committee CEN/TC 214, Textile machinery and

ISO 22291:2022(E)
Introduction
This document was prepared simultaneously by ISO/TC 72 and CEN/TC 214, and adopted under the
Vienna Agreement in order to obtain identical standards on technical safety requirements for the
design and construction of wetlaid-nonwoven machinery.
This document is a type-C standard as stated in ISO 12100.
This document is of relevance, in particular, for the following stakeholder groups representing the
market players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— machine designers;
— systems integrators;
— health and safety bodies (regulators, accident prevention organisations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate at the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events
are covered are indicated in the Scope of this document. When requirements of this type-C standard are
different from those which are stated in type-A or type-B standards, the requirements of this type-C
standard take precedence over the requirements of the other standards for machines that have been
designed and built according to the requirements of this type-C standard.
For machines or machine equipment not dealt with in this document, the designer performs a risk
assessment according to ISO 12100 and provides means for reducing the risk from significant hazards.
These risk reduction measures that need to be identified by the designer/manufacturer of the
machinery by risk assessment are outside the scope of this document.
This document contains a summary of general safety requirements and/or protective/risk reduction
measures for frequently occurring hazards of wetlaid-nonwoven machinery (see Clause 5) which apply
whenever referred to in this document.
Specific hazards and corresponding specific safety requirements and/or protective/risk reduction
measures for certain machine elements (e.g. winders) and their combination of wetlaid-nonwoven
machines are also described (see Clause 6).

INTERNATIONAL STANDARD ISO 22291:2022(E)
Safety requirements for wetlaid-nonwoven machinery
1 Scope
This document specifies safety requirements and means of verification for wetlaid-nonwoven
machinery.
This document applies to wetlaid-nonwoven machines, including approach flow system, headbox, wire
section and jet head, hydroentangling unit, dryer, finishing, quality control system (QCS), winder, drives
and control system. Annex C illustrates general wetlaid-nonwoven machinery and their components.
It deals with all significant hazards, hazardous situations and hazard events relevant to wetlaid-
nonwoven machines, when used as intended and under the conditions foreseeable by the manufacturer.
This document does not deal with pressure hazards in steam-heated drying cylinders and does not
apply to equipment under pressure.
This document does not apply to machines which are intended for use in explosive atmospheres.
This document does not apply to wetlaid-nonwoven machines which have been manufactured before
the date of publication of this document.
