European foreword
This document (EN 17116-3:2019) has been prepared by Technical Committee CEN/TC 214 “Textile
machinery and accessories”, the secretariat of which is held by SNV.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by January 2020, and conflicting national standards shall
be withdrawn at the latest by January 2020.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
This document is based on ISO 9398-3 extended by the application of the state of the art methodology
to measure performance and has been prepared by the EUP Lot 24 Working Group of VDMA — ETCT
European Textile Care Technology and CEN/TC 214 in collaboration with wfk-Cleaning Technology
Institute, Germany.
The standard testing procedure for continuous tunnel washer is based on ISO 9398-3. It includes among
others the references EN ISO 10472-1 and EN ISO 10472-3.
European Standard requirements.
ISO 9398-3:2003 is extended by state of the art methodology to measure performance. Significant
technical differences from ISO 9398-3:2003 are:
a) more detailed description of testing procedure;
b) changed test conditions under practical in situ laundry conditions;
c) introduction of a new type of test load;
d) implementation of energy consumption of various heat sources;
e) implementation of air compressor energy consumption;
f) implementation of detergent consumption;
g) implementation of washing performance, as stain/soil removal, secondary wash performance and
rinse performance;
h) comparison of wash performance with reference washing machine.
Contrary to washer extractors, dewatering of the load is carried out in separate machines, like presses
or centrifuges. Therefore, these machines are not content of this standard.
A bilingual version of this publication may be issued at a later date.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, 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, Turkey and the
United Kingdom.
1 Scope
This document defines the characteristics of continuous tunnel washer and gives the usual test methods
for these characteristics with regard to machine capacity, power consumption and productivity. It is
applicable for use as a reference in the drafting of purchasing orders for continuous tunnel washer. In
addition it is recommended for determination of energy consumption and productivity according to
Directive 2009/125 EC. This document excludes the energy consumption for dewatering of the load.
Furthermore, the document describes standard methods for measuring principal performance
characteristics of continuous tunnel washer. It does not cover safety requirements (see EN ISO 10472-
3).
