FprEN 12875-2 is a CEN draft European Standard for the visual inspection and evaluation of utensils after mechanical dishwashing testing. It tells laboratories, inspectors, manufacturers and suppliers how to judge visible changes on tested domestic articles and how to report and mark the result.

What does FprEN 12875-2 specify?

FprEN 12875-2 specifies the conditions for visual inspection of domestic articles after they have been tested for dishwashing resistance according to the relevant parts of the EN 12875 series. It covers a wide range of materials, so the same inspection approach can be used for many common utensil types.

The scope includes ceramic, glass, glass ceramic, decorated glass, plastics, rubber, silicones, metal, mineral based and plant-based products, as well as coated or enamelled articles and others. In practice, that means the document is aimed at evaluating appearance changes after dishwashing tests, not at running the dishwasher test itself.

The document is organized into clauses on scope, normative references, principle, inspectors, apparatus, samples, procedure, test report and marking. Annex A is informative and gives an inspection protocol with examples and report templates.

What are the key requirements of FprEN 12875-2?

FprEN 12875-2 centers on comparing tested samples with an unused reference sample under controlled viewing conditions. The key decisions are made from visible surface changes, so the document focuses on consistent inspection, repeatable scoring and clear reporting.

Inspection setup and samples

At least three tested samples are inspected, preferably from different lots, and a fourth unused specimen is kept as a reference. This helps the user see whether a result is representative of production rather than of one piece only.

At least two inspectors are required, and they must be familiar with the procedure, able to see clearly with the naked eye or normal vision aid, and have normal colour vision. The inspection site must be protected from outside light and use diffuse daylight-type illumination. In practice, this is to make the comparison between reference and tested articles as consistent as possible.

Before inspection, easily removable deposits are removed by wiping, or by hand washing with mild liquid detergent at about 45 °C followed by rinsing and drying. That prevents loose residue from being mistaken for dishwashing damage.

Inspection criteria and classification

The standard asks inspectors to judge changes, where applicable, in colour, gloss, clouding/hazing, resistant deposits, iridescent layers, corrosion products, deformation, cracking, delamination/loss of adhesion, and other aspects. The result is based on what can actually be seen on the surface, so users must pay attention to the most affected area.

Each applicable criterion is classified in three levels: no visible change, first discernible change, or clear visible change. Inspectors work independently, then the figures are averaged across inspectors and samples and rounded to one decimal. If any criterion averages above 1.0, the article is considered to show clearly visible changes.

Number of cycles, reporting and marking

FprEN 12875-2 links the visual result to a minimum number of 100 test cycles. Higher numbers can be claimed in multiples of 50, and if an article is made of more than one material, the lowest result governs the claim. For mixed-material articles, this matters because one weak component controls the statement on dishwasher resistance.

The test report has to identify the document used, the articles tested, the sampling place and dates, the test method applied, the inspectors, the maximum cycle count achieved without exceeding the 1.0 average limit, and the final category and averages. The marking clause then allows a symbol or wording for articles tested according to prEN 12875-1 and evaluated under this document, and a descriptive marking for ceramic articles tested according to EN 12875-4 or EN 12875-5.

What terms does FprEN 12875-2 use?

• Dishwashing resistance - the ability of an article to withstand dishwashing without clear visible change after testing.
• Inspection criteria - the surface features that inspectors judge, such as colour, gloss, cracking or delamination.
• Unused sample - the reference article used for side-by-side comparison with the tested samples.
• First discernible change - the earliest visible difference from the reference, seen only by careful comparison.
• Clear visible change - a change that is plainly visible and significant enough to end the test for that criterion.
• Test cycles - repeated dishwashing test runs used to build the resistance result.
• Marking - the symbol or wording used to communicate the tested resistance result on the article or packaging.

Who uses FprEN 12875-2?

FprEN 12875-2 is used by testing laboratories, inspectors and quality teams that evaluate how articles look after dishwashing tests. It is also relevant to manufacturers and suppliers of domestic utensils made from the covered materials, because they need a consistent way to document results and support dishwasher-resistant claims.

The document is especially relevant for products in cookware, cutlery and flatware, and for items that may be sold with a dishwasher resistance marking.

What changed in FprEN 12875-2 from the previous edition?

FprEN 12875-2 supersedes EN 12875-2:2001. The foreword lists these technical changes:

• scope extended to include non-metallic articles
• minor adjustments to the evaluation procedure
• clearer evaluation criteria
• addition of a section on number of test cycles
• addition of an alternative marking
• addition of informative Annex A, Inspection protocol
• editorial changes

Which standards are used with FprEN 12875-2?

FprEN 12875-2 cites prEN 12875-1, Mechanical dishwashing resistance of utensils - Part 1: Reference test method for domestic articles. That part supplies the dishwashing test method that produces the samples inspected here.

The introduction also names related parts of the same series:

• Part 1 - reference test method for domestic articles
• Part 4 - rapid test for domestic ceramic articles
• Part 5 - rapid test for ceramic catering articles

These parts matter because FprEN 12875-2 is the inspection and evaluation step used after the relevant test method.

What does the FprEN 12875-2 document contain?

The document contains a procedure for preparing samples, inspecting them under defined viewing conditions, scoring visible changes, and converting those scores into a resistance result. It also contains the reporting content needed to document the outcome clearly.

Annex A gives an informative inspection protocol with worked examples for classification and failure detection. It also provides templates that can be used for the test report. The document additionally includes a marking figure and a bibliography entry for colour-blindness testing and graphical symbols.
