The recipient is advised to consider seeking professional guidance with respect to its use of this publication.

This publication is not intended to constitute a contract. Users are responsible for its correct application.

This publication has been prepared under a mandate given to the European Standards Organizations by the European Commission and the European Free Trade Association. It is intended to support requirements of the EU legislation detailed in the European Foreword. A European Annex, usually Annex ZA or ZZ, describes how this publication relates to that EU legislation.

For the Great Britain market (England, Scotland and Wales), if UK Government has designated this publication for conformity with UKCA marking (or similar) legislation, it may contain an additional National Annex. Where such a National Annex exists, it shows the correlation between this publication and the relevant UK legislation. If there is no National Annex of this kind, the relevant Annex ZA or ZZ in the body of the European text will indicate the relationship to UK regulation applicable in Great Britain. References to EU legislation may need to be read in accordance with the UK designation and the applicable UK law. Further information on designated standards can be found at www.bsigroup.com/standardsandregulation.

For the Northern Ireland market, UK law will continue to implement relevant EU law subject to periodic confirmation. Therefore Annex ZA/ZZ in the European text, and references to EU legislation, are still valid for this market.

UK Government is responsible for legislation. For information on legislation and policies relating to that legislation, consult the relevant pages of www.gov.uk.

Compliance with a British Standard cannot confer immunity from legal obligations.

This British Standard was published under the authority of the Standards Policy and Strategy Committee on 30 November 2026.

This European Standard was approved by CEN on 28 September 2026.

CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard the status of a national standard without any alteration. Up-to-date lists and bibliographical references concerning such national standards may be obtained on application to the CEN-CENELEC Management Centre or to any CEN member.

This European Standard exists in three official versions (English, French, German). A version in any other language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has the same status as the official versions.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czechia, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and United Kingdom.

Introduction

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 the 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 specifies general safety requirements for self-loading mobile concrete mixers (here-after referred to as “SLMs”) as defined in ISO 18650‑1:2021, with rigid or articulated wheeled chassis.

This document applies to SLMs which are designed for front or rear loading and can be provided with a slewing and/or tilting frame where the rotating drum and the self-loading equipment (lift arms and bucket) are mounted on. SLMs can also be fitted with accessories such as water dosing means and a weighing system.

This document is not applicable to the following:

machines designed primarily for earth moving, such as loaders or dumpers (see applicable parts of the EN 474 series);
truck mixers (see EN 12609).

This document deals with all significant hazards, hazardous situations and events relevant to SLMs, whether used as intended and under conditions foreseen or under conditions of misuse reasonably foreseeable by the manufacturer (see Annex A).

This document does not provide performance levels required for safety related functions of control systems.

NOTE A document providing detailed description of safety functions for SLMs and related performance levels required is under development.

This document does not address hazards that can occur:

during manufacture;
when using SLMs on public roads, where specific local road regulations can apply;
when operating in potentially explosive atmospheres.

This document does not address hazards specifically related to:

SLMs designed to operate with varying levels of autonomy or when SLMs have embedded safety-systems with fully or partially self-evolving behaviour or logic using machine learning approaches, including collaborative applications;
SLMs when intended to be connected to the internet or to an external network or device that communicates with it (protection against corruption).

This document is not applicable to SLMs manufactured before the date of its publication.
