Machines for mechanical processing of minerals and similar solid materials - Safety - Part 5: Specific requirements for cleaning, recycling, sorting and mud treatment machinery

This part of prEN 1009 to be used together with prEN 1009-1, specifies the safety requirements and their verification for the design and construction of machinery for cleaning, water recycling, mud treatment and sorting (other than screens) for the mechanical processing in quarrying, recycling and processing mineral and by-products. In addition, it specifies the type of information on safe working practices (including residual risks) to be provided by the manufacturer.
The requirements of this part are complementary to the common requirements formulated in prEN 1009-1. This part does not repeat the requirements from prEN 1009-1, but adds or replaces them. When requirements of this part of prEN 1009 are different from those which are stated in prEN 1009-1, the requirements of this part of prEN 1009 take precedence over the requirements of prEN 1009-1 for machines that have been designed and built according to the provisions of this part of prEN 1009.
This part of prEN 1009, together with prEN 1009-1, deals with all the significant hazards, hazardous situations and events relevant to machinery for cleaning, recycling, mud treatment when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer associated with the whole lifetime of the machine (see Clause 4).
NOTE 1   EN 13309 specifies test methods and acceptance criteria for evaluating the electromagnetic compatibility of all kind of mobile construction machinery.
NOTE 2   Specific requirements related to road traffic regulations (e.g. lighting, dimensions, speed limit plate) are not taken into account in this standard.
This part of prEN 1009 is not applicable to machinery for cleaning, recycling, mud treatment which are manufactured before the date of publication of this document by CEN.

Maschinen für die mechanische Aufbereitung von Mineralien und ähnlichen festen Stoffen - Sicherheit - Teil 5: Spezifische Anforderungen für Reinigungs-, Recycling-, Sortier- und Schlamm-Verarbeitungsmaschinen

Dieser Teil der prEN 1009, der zusammen mit prEN 1009-1 anzuwenden ist, legt die Sicherheitsabforderungen und ihre Überprüfung für die Auslegung und Konstruktion von Maschinen zur Reinigung, Wasseraufbereitung, Schlamm-Verarbeitung und Sortierung (keine Siebe) für die mechanische Aufbereitung im Sinne von Abbau, Recycling und Aufbereitung von Mineralien und Nebenprodukten fest. Zusätzlich legt er fest, welche Informationen zum sicheren Betrieb (einschließlich Restgefahren) vom Hersteller zur Verfügung zu stellen sind.
Die Anforderungen dieses Teils ergänzen die gemeinsamen Anforderungen aus prEN 1009-1. In diesem Teil werden die Anforderungen aus prEN 1009 1 nicht wiederholt, sondern ergänzt oder ersetzt. Wenn Anforderungen dieses Teils der prEN 1009 von in prEN 1009-1 beschriebenen abweichen, haben die Anforderungen dieses Teils der prEN 1009 für Maschinen, die entsprechend den Anforderungen dieses Teils der prEN 1009 ausgelegt und konstruiert wurden, Vorrang vor den Anforderungen von prEN 1009-1.
Dieser Teil der prEN 1009 befasst sich zusammen mit prEN 1009 1 mit allen signifikanten Gefährdungen, Gefährdungssituationen und -ereignissen, die für Reinigungs-, Recycling- und Schlamm-Verarbeitungsmaschinen gelten, wenn sie bestimmungsgemäß und unter den vom Hersteller in Verbindung mit der Maschinenlebensdauer vorhersehbaren Bedingungen verwendet werden (siehe Abschnitt 4).
ANMERKUNG 1   EN 13309 legt Prüfverfahren und Abnahmekriterien zur Bewertung der elektromagnetischen Verträglichkeit für alle Arten mobiler Baumaschinen fest.
ANMERKUNG 2   Besondere Anforderungen im Hinblick auf Regularien des Straßenverkehrs (z. B. Beleuchtung, Abmessungen, Geschwindigkeitsanforderungen, Kennzeichen) werden in dieser Norm nicht berücksichtigt.
Dieser Teil der prEN 1009 gilt nicht für Reinigungs-, Recycling- und Schlamm-Verarbeitungsmaschinen, die vor dem Datum der Veröffentlichung dieses Dokuments durch CEN hergestellt wurden.

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);

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 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, to be used together with EN 1009-1, specifies the safety requirements and their

verification for the design and construction of machinery for cleaning, water recycling, mud treatment

and sorting (other than screens) for the mechanical processing in quarrying, recycling and processing

mineral and by-products. In addition, it specifies the type of information on safe working practices

(including residual risks) to be provided by the manufacturer.

When requirements of this part of EN 1009 are different from those which are stated in EN 1009-1:2020,

the requirements of this part of EN 1009 take precedence over the requirements of EN 1009-1:2020 for

machines that have been designed and built according to the provisions of this part of EN 1009.

This document, together with EN 1009-1:2020, deals with all the significant hazards, hazardous

situations and events relevant to machinery for cleaning, recycling, mud treatment when they are used

as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer

associated with the whole lifetime of the machine (see Annex C).
This document does not cover:
— design relating to road traffic regulations;

— hazards arising from the use of the machines in potentially explosive atmospheres as well as from

processing of explosive materials and risks related to electromagnetic compatibility;

— specific hazards related to mobile machinery.

NOTE 1 EN ISO 13766-1 and EN ISO 13766-2 specify test methods and acceptance criteria for evaluating the

electromagnetic compatibility of all kinds of mobile construction machinery.

NOTE 2 prEN 1009-6 “Specific requirements for mobile and semi mobile equipment” is under preparation to

cover specific requirements (e.g. mobility, braking, access, frequent transportation), including exceptions and

additional requirements for mobile and semi mobile equipment. This means that mobile machines are not covered

as long as EN 1009-6 is not published by CEN.

This document is not applicable to machinery for cleaning, recycling, mud treatment and sorting which

are manufactured before the date of publication of this document by CEN.
