This document deals with all significant hazards, hazardous situations and events, as listed in Annex A, which are relevant to stationary diamond wire saws (stationary diamond mono-wire saws and stationary diamond multi-wire saws), as defined in Clause 3.
Stationary diamond wire saws may be used in quarries or in sawmill for cutting natural stones (e.g. marble, granite), when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Annex A).
This document deals only with stationary diamond wire saws using coated diamond wire as tool.
This document specifies the appropriate technical measures to eliminate or reduce risks arising from the significant hazards.
This document deals all significant hazards that may occur within the expected lifetime of the machinery including the phases of transport, assembly, dismantling, disabling and scrapping.
This document does not deal with the significant hazards arising by the use of other facilities/devices not described in this document, that may be fitted on the machines or that may be used during the work cycle.
This document does not deal with:
a)   operation under extreme ambient conditions (outside the limits defined in EN 60204-1:2018);
b)   upstream and downstream conveying elements, not integrated with stationary diamond wire saws, for transporting of the work-pieces.
This document is not applicable to machines which are manufactured before the date of publication of this document by CEN.

European foreword

This document (prEN 15163-1:2020) has been prepared by 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 15163:2017.

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(s), see informative Annex ZA, which is an integral part of this

document.

This document deals with safety requirements of stationary diamond wire saws previously treated in

EN 15163:2017 with safety requirements of transportable diamond wire saws now treated in

prEN 15163-2:2020. As safety requirements related two types of machines have been separated, this

document edition is completely different from the previous one.

Safety requirements treated in Clause 4, information for use treated in Clause 5 and related annexes have

been deeply modified, in addition, the following changes have been introduced:

— list of the significant hazards has been moved from Clause 4 to Annex A, according to Clause 6.10.3.1

of CEN Guide 414;
— normative references have been modified and updated to Clause 2;

— new terms and definitions have been introduced and improved to Clause 3 (e.g. coated diamond

wire);
— Annex ZA has been modified according to the last edition of CEN Guide 414.

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 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.

1 Scope

This document deals with all significant hazards, hazardous situations and events, as listed in Annex A,

which are relevant to stationary diamond wire saws (stationary diamond mono-wire saws and stationary

diamond multi-wire saws), as defined in Clause 3.

Stationary diamond wire saws may be used in quarries or in sawmill for cutting natural stones (e.g.

marble, granite), when they are used as intended and under conditions of misuse which are reasonably

foreseeable by the manufacturer (see Annex A).

This document deals only with stationary diamond wire saws using coated diamond wire as tool.

This document specifies the appropriate technical measures to eliminate or reduce risks arising from the

significant hazards.

This document deals all significant hazards that may occur within the expected lifetime of the machinery

including the phases of transport, assembly, dismantling, disabling and scrapping.

This document does not deal with the significant hazards arising by the use of other facilities/devices not

described in this document, that may be fitted on the machines or that may be used during the work cycle.

This document does not deal with:

a) operation under extreme ambient conditions (outside the limits defined in EN 60204-1:2018);

b) upstream and downstream conveying elements, not integrated with stationary diamond wire saws,

for transporting of the work-pieces.
