EN 12875-1:2005 (E) 3 Foreword This European Standard (EN 12875-1:2005) has been prepared by Technical Committee CEN/TC 194 “Utensils in contact with food”, the secretariat of which is held by BSI. 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of an identical text or by endorsement, at the latest by November 2005, and conflicting national standards shall be withdrawn at the latest by November 2005. This document supersedes ENV 12875-1:1998. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

EN 12875-1:2005 (E) 4 Introduction This European Standard specifies a test method for the determination of the mechanical dishwashing resistance of domestic articles. The results obtained according to this document are intended to serve for comparison purposes for the dishwashing resistance of the different domestic articles and give an indication of resistance only under the standard conditions of this test. The dishwasher test method described in this document is both time consuming and expensive. However, no single accelerated and inexpensive test is available which gives comparable results to the dishwasher test for the whole variety of utensils made of various materials which are cleaned in dishwashers. The test method described here is to be used as a reference method for dishwashing resistance. Accelerated test methods may be used instead of the reference test method provided that valid comparison to the dishwasher test is shown. NOTE Consideration should be given to the normal use of each type of domestic article and its normal frequency of mechanical dishwashing. Further parts of EN 12875, under the general title Mechanical dishwashing resistance of utensils, that have already been published or are in preparation are as follows: Part 2: Inspection of non-metallic articles Part 4: Rapid test for domestic ceramic articles Part 5: Rapid test for ceramic catering articles SIST EN 12875-1:2005



EN 12875-1:2005 (E) 5 1 Scope This European Standard specifies a method for testing the resistance of domestic articles made from ceramic, glass, glass ceramic, vitreous enamel, metal and plastics under the combined chemical, thermal and mechanical stresses of mechanical dishwashing in domestic dishwashers. It specifies a reference test method for domestic dishwashing only. It does not define the number of dishwashing cycles which any given product shall withstand. 2 Normative references The following referenced documents are indispensable for the application of this document.
