Council Directive 84/500/EEC of 15 October 1984 on the approximation of the laws of the Member States relating to ceramic articles intended to come into contact with foodstuffs
1. This Directive is a specific Directive within the meaning of Article 3 of Directive 76/893/EEC.
2. This Directive concerns the possible migration of lead and cadmium from ceramic articles which, in their finished state, are intended to come into contact with foodstuffs, or which are in contact with foodstuffs, and are intended for that purpose.
3. 'Ceramic articles' means articles manufactured from a mixture of inorganic materials with a generally high argillaceous or silicate content to which small quantities of organic materials may have been added. These articles are first shaped and the shape thus obtained is permanently fixed by firing. They may be glazed, enamelled and/or decorated.
1. The quantities of lead and cadmium transferred from ceramic articles shall not exceed the limits laid down below.
2. The quantities of lead and cadmium transferred from ceramic articles shall be determined by means of a test, the conditions of which are specified in Annex I, using the method of analysis described in Annex II.
3. Where a ceramic article consists of a vessel fitted with a ceramic lid, the lead and/or cadmium limit which may not be exceeded (mg/dm2 or mg/litre) shall be that which applies to the vessel alone.
The vessel alone and the inner surface of the lid shall be tested separately and under the same conditions.
The sum of the two lead and/or cadmium extraction levels thus obtained shall be related as appropriate to the surface area or the volume of the vessel alone.
4. A ceramic article shall be recognized as satisfying the requirements of this Directive if the quantities of lead and/or cadmium extracted during the test carried out under the conditions laid down in Annexes I and II do not exceed the following limits:
1.2.3 // // Pb // Cd // - Category 1: // // // Articles which cannot be filled and articles which can be filled, the internal depth of which, measured from the lowest point to the horizontal plane passing through the upper rim, does not exceed 25 mm // 0,8 mg/dm2 // 0,07 mg/dm2 // - Category 2: // // // All other articles which can be filled // 4,0 mg/l // 0,3 mg/l // - Category 3: // // // Cooking ware; packaging and storage vessels having a capacity of more than three litres // 1,5 mg/l // 0,1 mg/l
5. However, where a ceramic article does not exceed the above quantities by more than 50 %, that article shall nevertheless be recognized as satisfying the requirements of this Directive if at least three other articles with the same shape, dimensions, decoration and glaze are subjected to a test carried out under the conditions laid down in Annexes I and II and the average quantities of lead and/or cadmium extracted from those articles do not exceed the limits set, with none of those articles exceeding those limits by more than 50 %.
The amendments to be made to the Annexes in the light of developments in scientific and technical knowledge, with the exception of sections 1 and 2 of Annex I, shall be adopted in accordance with the procedure laid down in Article 10 of Directive 76/893/EEC.
1. Within three years of notification (1) of this Directive, the Council shall determine in accordance with the procedure laid down in Article 100 of the Treaty:
(a) the limitations to be imposed on those areas of ceramic articles with which the mouth is intended to come into contact;
(b) the methods for checking that the limitations provided for in (a) are complied with.
2. Within the same period, the Commission shall, on the basis of toxicological and technological data, re-examine the limits laid down in Article 2, with a view to reducing them, and the lighting conditions for the test specified in Annex I, and shall, if appropriate, submit to the Council proposals for amendments to the Directive.
1. The Member States shall, if necessary, amend their national laws to comply with this Directive so that:
- three years after the notification of this Directive, trade in ceramic articles which comply with its provisions is permitted,
- five years after the notification of this Directive, the placing on the market of ceramic articles which do not comply with its provisions is prohibited.
They shall forthwith inform the Commission of any such amendment.
2. Without prejudice to paragraph 1, Member States may prohibit or continue to prohibit the manufacture of ceramic articles which do not comply with this Directive.
This Directive is addressed to the Member States.

BASIC RULES FOR DETERMINING THE MIGRATION OF LEAD AND CADMIUM
1. Test liquid ('simulant')
4 % (v/v) acetic acid, in a freshly prepared aqueous solution.
2. Test conditions
2.1. Carry out the test at a temperature of 22 Β± 2 Β°C for a duration of 24 Β± 0,5 hours.
2.2. When the migration of lead is to be determined, cover the sample by an appropriate means of protection and expose it to the usual lighting conditions in a laboratory.
When the migration of cadmium or of lead and cadmium is to be determined, cover the sample so as to ensure that the surface to be tested is kept in total darkness.
3. Filling
3.1. Samples which can be filled
Fill the article with a 4 % (v/v) acetic acid solution to a level no more than 1 mm from the overflow point; the distance is measured from the upper rim of the sample.
Samples with a flat or slightly sloping rim should be filled so that the distance between the surface of the liquid and the overflow point is no more than 6 mm measured along the sloping rim.
3.2. Samples which cannot be filled
The surface of the sample which is not intended to come into contact with foodstuffs is first covered with a suitable protective layer able to resist the action of the 4 % (v/v) acetic acid solution. The sample is then immersed in a recipient containing a known volume of acetic acid solution in such a way that the surface intended to come into contact with foodstuffs is completely covered by the test liquid.
4. Determination of the surface area
The surface area of the articles in category 1 is equal to the surface area of the meniscus formed by the free liquid surface obtained by complying with the filling requirements set out in section 3 above.
ANNEX II
METHODS OF ANALYSIS FOR DETERMINING THE MIGRATION OF LEAD AND CADMIUM
1. Object and field of application
The method allows the specific migration of lead and/or cadmium to be determined.
2. Principle
The determination of the specific migration of lead and/or cadmium is carried out by atomic absorption spectrophotometry.
3. Reagents
- All reagents must be of analytical quality, unless otherwise specified.
- Where reference is made to water, this always means distilled water or water of equivalent quality.
3.1. 4 % (v/v) acetic acid, in aqueous solution
Add 40 ml of glacial acetic acid to water and make up to 1 000 ml.
3.2. Stock solutions
Prepare stock solutions containing 1 000 mg/litre of lead and at least 500 mg/litre of cadmium respectively in a 4 % acetic acid solution (3.1).
4. Instruments
4.1. Atomic absorption spectrophotometer
The instrument's detection limit for lead and cadmium must be equal to or lower than:
- 0,1 mg/litre for lead,
- 0,01 mg/litre for cadmium.
The detection limit is defined as the concentration of the element in 4 % acetic acid (3.1) which gives a signal equal to twice the background noise of the instrument.
5. Method
5.1. Preparation of the sample
The sample must be clean and free from grease or other matter likely to affect the test.
Wash the sample in a solution containing a household liquid detergent at a temperature of approximately 40 Β°C. Rinse the sample first in tapwater and then in distilled water or water of equivalent quality. Drain and dry so as to avoid any stain. The surface to be tested should not be handled after it has been cleaned.
5.2. Determination of lead and/or cadmium
- The sample thus prepared is tested under the conditions laid down in Annex I.
- Before taking the test solution for determining lead and/or cadmium, homogenize the content of the sample by an appropriate method which avoids any loss of solution or abrasion of the surface being tested.
- Carry out a blank test on the reagent used for each series of determinations.
- Carry out determinations for lead and/or cadmium under appropriate conditions by atomic absorption spectrophotometry.
