European foreword
This document (prEN 12875-1:2024) has been prepared by Technical Committee CEN/TC 194 “Utensils
in contact with food”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 12875-1:2005.
This document includes the following significant technical changes with respect to EN 12875-1:2005:
— Adaptation of the test to the state of the art (test cycle, water quantity, detergent and rinse aid);
— Number of test cycles;
— Editorial changes.
Introduction
This document 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 intended 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.
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 are as
follows:
— Part 2: Inspection and evaluation
— Part 4: Rapid test for domestic ceramic articles
— Part 5: Rapid test for ceramic catering articles
1 Scope
This document specifies a method for testing the resistance of domestic articles made from ceramic, glass,
glass ceramic, decorated glass, vitreous enamel, coatings, rubber, silicones, 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. The minimum number of dishwashing
cycles is defined in EN 12875-2.

4 Principle
Unused articles are repeatedly exposed to a standardized test cycle in a test dishwasher which simulates
usual household dishwashing machines. The test dishwasher is a machine in which a washing cycle
consists of several partial steps: a cleaning step using alkaline cleaner, an intermediate rinse step, and the
final rinse during which a rinse aid is added. The washing cycle is followed by a drying step.
The test dishwasher is fully loaded.
After testing the articles are inspected for deviations from the original according to the conditions
specified in the relevant standards (e.g. prEN 12875-2) and legislations for various groups of products.
5 Reagents
5.1 Water
The water used shall be potable water and shall have a temperature of (15 ± 5) °C. It should be softened
by a cation exchanger to a value ≤ 0,1786 mmol/l, when tested in accordance with ISO 6059.
NOTE 1 If the conditions cannot be reached, the water softener of the dishwasher can be used in accordance with
this document.
−1
For testing metal articles, the chloride ion content shall not exceed 200 mg⋅l when determined in
accordance with ISO 9297.
−1
For testing plastics articles, the copper content shall not exceed 0,03 mg⋅l when determined in
accordance with ISO 8288.
NOTE 2 A higher copper content results in a noticeable yellowing of plastics.
5.2 Cleaning and rinse agents
Reference detergents shall be used as well as standard rinsing agents. For the composition and sources
of supply, see EN 60436.
Quantity of detergent and rinse aid shall be applied according to EN 60436.
NOTE When using a dishwasher with 12 place setting the amount of the detergent is (20 ± 1) g and the amount
of rinse aid is (3 ± 0,3) ml according to EN 60436.
6 Features of the test dishwasher
6.1 Water softener (cation exchanger), which shall be controlled to give a water hardness
