European foreword

This document (prEN 15163-2:2020) 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 15163-2:2017.

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 transportable diamond wire saws previously treated in

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

prEN 15163-1:2020. As safety requirements related two types of machines have been separated, this

standard 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. transportable

diamond wire saw; coated diamond wire, cutting operations);
— 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.
