die bei Trocknern und insbesondere bei Tumblern mit einem nutzbaren Nettovolumen der Trommel > 160 l,
Tunnel-Finishern einschließlich damit verbundener Transportvorrichtungen und Kabinett-Trocknern, auftreten.
Dieser Teil der ISO 10472 ergänzt die grundlegenden Anforderungen von ISO/TR 12100-1 und ISO/TR 12100-2.
Er gibt dem Konstrukteur Anleitung bei der Einschätzung der mit den Gefährdungen verbundenen Risiken und
zur Auswahl von Maßnahmen zur Erreichung des erforderlichen Sicherheitsniveaus.
Zusatzgeräte werden in diesem Teil der ISO 10472 nicht behandelt.

Overview

EN ISO 10472-4:2008 - Safety requirements for industrial laundry machinery - Part 4: Air dryers (ISO 10472-4:1997) is the CEN-adopted European version of the ISO technical specification addressing safety of industrial air-drying equipment. It focuses on tumble dryers (net usable cage volume > 160 L), tunnel finishers (including conveyors and cabinet dryers), and related hazards. The standard complements the common requirements in ISO 10472-1 and general machinery safety guidance in ISO/TR 12100‑1/2.

Key topics and requirements

The standard systematically identifies hazards and specifies safety measures and verification steps for air dryers. Main technical topics include:

• Hazard identification specific to air dryers: mechanical, electrical, thermal, noise, materials/substances, fire/explosion and control-system failures.
• Mechanical hazards: risks from rotating cages (entanglement), power-operated doors (crushing/shearing), tunnel finisher conveyors and loading/unloading movements.
• Electrical safety: alignment with machinery electrical equipment principles (see EN/IEC 60204‑1).
• Thermal risks: protection against hot surfaces, steam spray and heated loading/unloading zones.
• Materials and substances: fire and explosion risk reduction and handling of chemicals used in laundering processes.
• Safety measures and verification: design solutions, guarding, interlocks, pressure-sensitive devices and testing/verification procedures to confirm compliance.
• User information: requirements for instruction handbooks, warning signs and operational guidance.
• Regulatory linkage: informative annexes (ZA and ZB) map the standard to Essential Requirements of EU Machinery Directives (98/37/EC and 2006/42/EC), giving a presumption of conformity when implemented.

Practical applications and users

This standard is intended for stakeholders involved in the design, manufacture, installation, operation and compliance of industrial laundry air-drying equipment:

• Machine designers and OEMs developing tumble dryers, tunnel finishers and cabinet dryers
• Safety engineers and risk assessors carrying out machine risk assessments
• Compliance officers and technical managers ensuring conformity with the Machinery Directive
• Procurement teams specifying safety features for industrial laundry equipment
• Service, maintenance and validation personnel implementing verification and testing routines
• Notified bodies and testing laboratories assessing conformity to relevant machinery safety requirements

Related standards

EN ISO 10472‑4 is used together with:

• ISO 10472‑1 (Common requirements)
• ISO/TR 12100‑1 / 12100‑2 (Machinery safety principles)
• EN/IEC 60204‑1 (Electrical equipment of machines)
• ISO 6182‑1, EN 953, EN 1050 and other referenced safety standards listed in the normative references

By following EN ISO 10472‑4:2008, organizations can reduce mechanical, thermal and electrical risks associated with industrial air dryers and support regulatory compliance and safer machine design.

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 10472-4 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.
