5 Verdrag inzake het onderzoek en de stempeling van edelmetalen werken
Control by the authorised assay office(s)
5.1 Principle
5.1.1 Articles, which satisfy the criteria in Annex I, shall be marked with the Common Control Mark (CCM), as described in paragraph 5.5, in line with the requirements set out in the present Annex.
5.1.2 The CCM is applied together with other marks (some of which can be combined), which together provide the following minimum information on:
a) who has produced (or imported) the article: this is indicated by a registered responsibility mark as described in paragraph 5.4;
b) who has controlled the article: this is shown by the mark of the assay office;
c) what the precious metal content of the article is: this is indicated by a fineness mark in Arabic numerals; and
d) what precious metal the article is made of: this is shown by a mark, symbol or shape indicating the nature of the precious metal.
5.1.3 The Standing Committee determines which of these marks must be applied on articles and which can be combined.
5.2 Methods
The following are accepted methods of marking: punching and laser. The Standing Committee can decide on other methods of marking articles.
5.3 Display
Whenever possible, all marks shall be placed in immediate proximity to each other. Other marks (e.g. year mark), which are not to be confused with the marks mentioned above, are allowed as additional marks.
5.4 Register for responsibility marks
The responsibility mark referred to in letter a) of paragraph 5.1.2 shall be registered in an official register of the Contracting State and/or one of its assay offices, which controls the article in question.
5.5 The Common Control Mark (CCM)
5.5.1 Description
5.5.1.1 The CCM is a conformity mark indicating that the article of precious metals has been controlled in accordance with the Convention’s requirements, as contained in the present Annexes and the Compilation of Technical Decisions. It shall consist of the representation of a balance in relief on a lined background surrounded by a geometrically variable shield.
5.5.1.2 The CCM can be combined with a fineness and precious metal mark: in this case, it is surrounded by a shield indicating the nature of the precious metal and contains a number in Arabic numerals showing in relief the standard of fineness of the article in parts per thousand, as described below (Type 1).
5.5.1.3 The CCM can be a conformity mark only: in this case, it is surrounded by a standardised octagonal shield, as described below (Type 2).
Type 1 | Type 2
Platinum | Gold | Palladium | Silver
5.5.2 Approved sizes
The approved sizes of the CCM and other compulsory marks are defined by the Standing Committee.
5.6 Articles consisting of more than one alloy of the same precious metal
Where an article consists of different alloys of the same precious metal, the fineness mark and the CCM applied shall be that of the lowest fineness present in the article. Exceptions can be decided on by the Standing Committee.
5.7 Articles consisting of parts
If an article consists of parts which are hinged or readily separable, the above marks shall, when possible, be applied to the main part. Where practicable the CCM shall be applied also to the lesser parts.
5.8 Mixed precious metal articles
5.8.1 If an article consists of different precious metal alloys, and if the colour and extent of each alloy are clearly visible, the marks referred to in paragraph 5.1.2 shall be applied on one precious metal alloy and the appropriate CCM (Type 1) on the other(s).
5.8.2 If an article consists of different precious metal alloys and if the colour and extent of each alloy is not visible, the marks referred to in paragraph 5.1.2 and the corresponding CCM shall be applied on the least precious metal. The CCM relating to the more precious metals may not be applied.
5.8.3 Additional rules as well as exceptions justified by technical reasons are decided on by the Standing Committee.
5.9 Multimetal articles
5.9.1 The marks referred to in paragraph 5.1.2 shall be applied on the precious metal part of a multimetal article. The mark <METAL> (or equivalent) shall be applied on the metallic part in line with paragraph 2.6 of Annex I to the Convention.
5.9.2 The Standing Committee may decide on further details or exceptions.
