Introduction
This document has been prepared to be a harmonized standard to provide one means of conforming to
the essential health and safety requirements of the Machinery Directive and associated EFTA Regulations.
This document is a type-C standard as stated in EN 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);
— health and safety bodies (regulators, accident prevention organizations, 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 and 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.

1 Scope
This document applies to stationary surface-finishing machines with stationary work piece (see 3.1) or
with moving work piece (see 3.2) which are used to grind or polish horizontal surfaces of slabs, strips or
tiles of natural stone and engineered stone (e.g. agglomerated stone) as defined by EN 14618:2009.
This document deals with all significant hazards, hazardous situations and events relevant to surface-
finishing machines, when they are used as intended and under conditions of misuse which are reasonably
foreseeable by the manufacturer (see Clause 4).
This document specifies the appropriate technical measures to eliminate or reduce risks arising from the
significant hazards.
This document deals with the foreseeable lifetime of the machinery including the phases of transport,
assembly, dismantling, disabling and scrapping.
This document does not deal with:
— hand-held grinding machines;
— machines intended for operation in a potentially explosive atmosphere;
— operation in severe environmental conditions (e.g. extreme temperatures, corrosive environment);
— machines intended for outdoor operation.
This document is not applicable to machinery which is manufactured before the date of publication of
this document by CEN.

European foreword
This document (prEN 15571:2019) has been prepared by the Technical Committee CEN/TC 151
“Construction equipment and building material machines - Safety”, the secretariat of which is held by
DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 16564:2014.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association and supports essential requirements of
EU Directive(s).
For relationship with EU Directive 2006/42/EC, see informative Annex ZA which is an integral part of
this document.

Introduction
This document has been prepared to be a harmonized standard to provide one means of conforming to
the essential health and safety requirements of the Machinery Directive and associated EFTA Regulations.
This document is a type-C standard as stated in EN 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);
— health and safety bodies (regulators, accident prevention organizations, 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 and 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.

1 Scope
This document applies to stationary surface-finishing machines with stationary work piece (see 3.1) or
with moving work piece (see 3.2) which are used to grind or polish horizontal surfaces of slabs, strips or
tiles of natural stone and engineered stone (e.g. agglomerated stone) as defined by EN 14618:2009.
This document deals with all significant hazards, hazardous situations and events relevant to surface-
finishing machines, when they are used as intended and under conditions of misuse which are reasonably
foreseeable by the manufacturer (see Clause 4).
This document specifies the appropriate technical measures to eliminate or reduce risks arising from the
significant hazards.
This document deals with the foreseeable lifetime of the machinery including the phases of transport,
assembly, dismantling, disabling and scrapping.
This document does not deal with:
— hand-held grinding machines;
— machines intended for operation in a potentially explosive atmosphere;
— operation in severe environmental conditions (e.g. extreme temperatures, corrosive environment);
— machines intended for outdoor operation.
This document is not applicable to machinery which is manufactured before the date of publication of
this document by CEN.
