EN ISO 10472-2:2008

Safety requirements for industrial laundry machinery - Part 2: Washing machines and washer-extractors (ISO 10472-2:1997)

Covers together with ISO 10472-1, most significant hazards associated with washing machines and washer-extractors of all configurations having a net usable cage volume 60 l. This part does not cover particular hazards for drawer-type washer extractors. This part does not cover the hazards caused by processing work which may create an explosive or flammable atmosphere inside the machine. This part complements the basic requirements as laid down in ISO/TR 12100-1 and ISO/TR 12100-2. It also gives guidance to the designer on assessing the risks associated with the hazards (see EN 1050) and on selecting measures for attaining the required safety level.

Sicherheitsanforderungen für industrielle Wäschereimaschinen - Teil 2: Wasch- und Waschschleudermaschinen (ISO 10472-2:1997)

Dieser Teil der ISO 10472 behandelt, zusammen mit ISO 10472-1, die meisten wesentlichen Gefährdungen,
die auftreten bei der Verwendung von Wasch- und Waschschleudermaschinen jeder Art, deren Trommel ein
Nettonutzvolumen > 60 l hat.
Dieser Teil der ISO 10472 berücksichtigt nicht die besonderen Gefährdungen bei Schubladen-Waschschleudermaschinen.
Dieser Teil der ISO 10472 behandelt nicht die Gefährdungen, die bei der Bearbeitung von Waschgut
verursacht werden, das eine explosionsfähige oder brennbare Atmosphäre in der Maschine erzeugen kann.
Dieser Teil der ISO 10472 ergänzt die grundlegenden Sicherheitsanforderungen von ISO/TR 12100-1 und
ISO/TR 12100-2. Er gibt dem Konstrukteur auch Anleitung bei der Einschätzung der mit den Gefährdungen
(siehe EN 1050) verbundenen Risiken und bei der Auswahl von Maßnahmen zur Erreichung des
erforderlichen Sicherheitsniveaus.
Zusatzeinrichtungen, z. B. Dosierpumpen für Chemikalien, Dampfventile und Zuleitungen, Entlüftungssysteme
sowie Zufuhr- und Entnahmesysteme für das Waschgut und Ableitung ins Freie, werden in diesem Teil der
ISO 10472 nicht berücksichtigt.

Exigences de sécurité pour les machines de blanchisserie industrielle - Partie 2: Machines à laver et laveuses-essoreuses (ISO 10472-2:1997)

La présente partie de l'ISO 10472 couvre, avec l'ISO 10472-1, la plupart des phénomènes dangereux significatifs associés aux machines à laver et laveuses-essoreuses de tous types dont le tambour a un volume net utile supérieur à 60 l. La présente partie de l'ISO 10472 ne couvre pas les risques particuliers liés à l'utilisation des laveuses-essoreuses à tiroirs. La présente partie de l'ISO 10472 ne couvre pas les risques engendrés par le traitement du linge pouvant générer une atmosphère explosive ou inflammable à l'intérieur de la machine. La présente partie de l'ISO 10472 vient en complément des exigences fondamentales spécifiées dans l'ISO/TR 12100-1 et l'ISO/TR 12100-2. Elle guide également le concepteur dans l'évaluation des risques liés aux phénomènes dangereux (voir l'EN 1050) et dans le choix des mesures à prendre pour atteindre le niveau de sécurité requis. La présente partie de l'ISO 10472 n'est pas applicable au matériel connexe (par exemple stockage et pompes d'alimentation des produits chimiques, vannes vapeur et tuyauteries d'alimentation, systèmes d'évent et systèmes de chargement et de déchargement et d'évacuation dans l'air).

Overview

EN ISO 10472-2:2008 (ISO 10472-2:1997) specifies safety requirements for industrial laundry machinery - specifically washing machines and washer-extractors. Adopted by CEN, this part complements ISO 10472‑1 (common requirements) and covers the most significant hazards for machines with a net usable cage volume greater than 60 L. It is intended to guide designers, manufacturers and safety assessors on machine safety, risk reduction and conformity with applicable EU machinery directives (see informative Annexes ZA and ZB).

Key topics and technical requirements

The standard addresses hazards, safety measures and verification methods. Major technical topics include:

• Scope and normative references - relationship to ISO 10472‑1 and other relevant technical reports and standards.
• Definitions and terminology used for industrial laundry machinery.
• Hazard identification - systematic listing of likely hazards for washing machines and washer‑extractors.
• Mechanical hazards - rotating cages, manual and power‑operated drum doors, cage doors, loss of stability, suspended machines, falling loads and loading devices.
• Electrical hazards - requirements to reduce electrical risk per referenced electrotechnical standards.
• Thermal hazards - hot liquor, hot surfaces, heat energy and viewing panels.
• Noise and vibration - recognition of hazards generated by noise.
• Materials and chemical hazards - aggressive chemicals, fire/explosion risks and biological hazards.
• Ergonomics and human factors - design to avoid musculoskeletal risk and poor operation layout.
• Energy supply and control failures - safe behavior on loss of power or control malfunction.
• Particular machine types - additional measures for barrier machines and tilting machines (manual and automatic), loading/unloading, overturning and maintenance.
• Verification - procedures for verifying that safety requirements and measures are met.
• Information for use - documentation, instructions and warnings for safe operation and maintenance.

Applications and users

EN ISO 10472‑2 is practical for:

• Machine designers and OEMs developing industrial washing machines and washer‑extractors.
• Safety engineers performing risk assessments and specifying guards, interlocks and controls.
• Manufacturers preparing technical files for CE marking and demonstrating presumption of conformity with EU Directives (98/37/EC and 2006/42/EC as referenced).
• Procurement specifiers, inspection bodies and service/maintenance teams who need standard-based safety guidance.

Related standards

Normative references and complementary standards in the document include (but are not limited to):

• ISO 10472‑1 (Part 1: Common requirements)
• ISO/TR 12100‑1 / 12100‑2 (machine safety fundamentals)
• ISO 13849‑1 (safety‑related control systems)
• IEC 335 series, EN 349, EN 953, EN 1037

This standard is essential for achieving systematic, state‑of‑the‑art safety design and regulatory compliance for industrial laundry washing machines and washer‑extractors.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee has
been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates
closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical
standardization.
Draft International Standards adopted by the technical committees are circulated to the member bodies for
voting. Publication as an International Standard requires approval by at least 75 % of the member bodies
casting a vote.
International Standard ISO 10472-2 was prepared by Technical Committee ISO/TC 72, Textile machinery and
machinery for dry-cleaning and industrial laundering, Subcommittee SC 5, Industrial laundry and
dry-cleaning machinery.
ISO 10472 consists of the following parts, under the general title Safety requirements for industrial laundry
machinery:
— Part 1: Common requirements
— Part 2: Washing machines and washer-extractors
— Part 3: Washing tunnel lines including component machines
— Part 4: Air dryers
— Part 5: Flatwork ironers, feeders and folders
— Part 6: Ironing and fusing presses

Introduction
This part of ISO 10472 is intended to instruct the designer of industrial laundry machinery in a systematic
manner, focusing on his particular type of machine, regarding the relevant essential safety requirements,
and to suggest possible state-of-the-art safety solutions.
The extent to which hazards are covered is indicated in the scope of this part of ISO 10472. In addition,
machinery should comply as appropriate with ISO/TR 12100-1 and ISO/TR 12100-2 for hazards which are not
specifically referred to in this part of ISO 10472.
All examples given in this part of ISO 10472 represent the state of the art. Equivalent solutions are
acceptable, provided they attain at least the same safety level.
The designer is presumed to have taken into account all the provisions of ISO 10472-1 before considering
this part of ISO 10472.
