Foreword
This European Standard (EN 71-5:1993/A1:2006) has been prepared by Technical Committee CEN/TC 52

This Amendment to the European Standard EN 71-5:1993 shall be given the status of a national standard,
either by publication of an identical text or by endorsement, at the latest by July 2006, and conflicting national
standards shall be withdrawn at the latest by July 2006.
This European Standard has been prepared under a mandate given to CEN by the European Commission
and the European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this European
Standard.
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, Romania, Slovakia, Slovenia, Spain, Sweden,
Switzerland and United Kingdom.

following the 6 paragraph:
Under a mandate given to CEN by the European Commission, test methods were developed to determine the
migration and emission of the following substances or compounds, respectively:
• elements in ceramic and vitreous enamelling materials;
• plasticizers in oven hardening poly (vinyl chloride) (PVC) modelling clay sets;
• toluene, xylene and benzene in oven hardening plasticized PVC modelling clay sets and plastic moulding
sets;
• styrene in plastic moulding sets;
• substances in photographic processing sets;
• organic solvents in adhesives, lacquers, paints etc. and
• modifiers, film builders and plasticizers in paints and lacquers.
Five lead laboratories worked out the relevant test methods. In a second step the developed test procedures
were validated by the lead and peer review laboratories using specially manufactured or specially selected
samples (see Annex D). All test methods have been supervised by CEN/TC 52/WG 5 which also developed
EN 71-4.

Add the following clause:
12 Test methods
12.1 General
All chemicals used for analysis shall be of analytical grade (pro analysis) or, if unavailable, the best technical
grade. Water shall be of grade 3 according to EN ISO 3696 or of a comparable quality, and demonstrably free
from analytes of interest.
The precision of volumetric glassware should be grade A.
12.2 Determination of elements in ceramic and vitreous enamelling materials
12.2.1 Principle
The ceramic or enamel sample is submitted to a melting digestion using dilithium tetraborate. After the
dissociation the fused product is extracted by means of diluted hydrochloric acid. The individual metals are
determined by atomic emission spectrophotometry.
12.2.2 Standards and reagents
12.2.2.1 Standards

12.2.4 Preparation of standard solutions
12.2.4.1 Multi-element standard solution I
c (Cu, Fe, Pr, Co, Zr, V, Sn) = 10 mg/l
Pipette (1,0 ± 0,01) ml of each of the 1 000 mg/l standards (12.2.2.1) into a 100-ml volumetric flask. Add 10 ml
of hydrochloric acid (12.2.2.2), mix and make up to the mark with water.
NOTE The multi-element standard solution I may be stored for a month in a refrigerator at (4 ± 2) ºC.
12.2.4.2 Multi-element standard solution II
c (Cu, Fe, Pr, Co, Zr, V, Sn) = 5,0 mg/l
Pipette (50 ± 0,05) ml of the multi-element standard solution I into a 100-ml volumetric flask. Add 10 ml of
hydrochloric acid, mix and make up to the mark with water.
This solution shall be freshly prepared.
12.2.4.3 Multi-element standard solution III
c (Cu, Fe, Pr, Co, Zr, V, Sn) = 1,0 mg/l
Pipette (10 ± 0,02) ml of the multi-element standard solution I into a 100-ml volumetric flask. Add 10 ml of
hydrochloric acid, mix and make up to the mark with water.
This solution shall be freshly prepared.
12.2.5 Blank solution
Add 10 ml hydrochloric acid to 90 ml water in a polyethene- or polytetrafluorethene (PTFE)-flask.
12.2.6 Sampling
Obtain three test portions from each colour of the material and treat them separately.
NOTE Homogenisation of the test portions is not necessary because the materials have been melted and are very
finely ground.
12.2.7 Sample preparation
Weigh (0,1 ± 0,05) g to the nearest 0,001 g of each test portion in a platinum crucible. Add 1 g of dilithium
tetraborate to the crucible and mix carefully. Heat the crucible in a muffle furnace to (1 000 ± 50) ºC for
120 min.
After cooling to approximately 500 ºC remove the crucible from the muffle furnace and transfer it into a glass
of water. Add 20 ml of hydrochloric acid. Heat the solution to boiling point and let it boil until complete
dissolution of the sample occurs. Transfer the solution into a 250-ml volumetric flask and filled up to the mark.
If silicon dioxide is precipitated, remove it by filtration.
12.2.8 Procedure
Determine the elemental concentrations using the wavelengths according to Table 18. In case of spectral
interference choose an alternative appropriate wavelength.
Table 18 — Wavelengths
Element Wavelength
nm
Copper (Cu) 324,752
Iron (Fe) 259,942
Praseodymium (Pr) 422,285
Cobalt (Co) 228,616
Zirconium (Zr) 339,198
Vanadium (V) 292,399
Tin (Sn) 189,932
After the verification of the calibration function the samples are measured.
Determine the blank solutions before analysing the solutions.
Recalibrate the analytical instruments frequently. To avoid memory effects perform also checks with the blank
solution.
12.2.9 Evaluation of results
12.2.9.1 General
The mean value of three test portions shall be given.
The metal contents are calculated according to Equation (1):

(c −c )×V × f

M = (1)
m
W ×10000
where
M is the content of the metal in the sample, in mass-%;

c is the concentration of the metal in the analytical solution, in mg/l;
sample
c is the concentration of the metal in the blank value solution, in mg/l;

V is the volume of the sample solution, in ml;
f is the dilution factor;
W is the weighed portion of the sample, in g.

The calculated contents of elements are compared with the maximum permitted element concentrations in the
compounds given in Table C.1. If these concentrations are not exceeded, the requirements of EN 71-5 are
fulfilled.
If the concentrations are exceeded, the concentration of compounds have to be calculated according to
