REFERENCE TEST METHOD FOR RELEASE OF NICKEL FROM
PRODUCTS INTENDED TO COME INTO DIRECT AND PROLONGED
CONTACT WITH THE SKIN

Introduction
This is a summary of the test method. Due to copyright regulations the full test method must be purchased from the nominated National Standards Body.
This method is used to determine whether the nickel released from products intended to come into direct and prolonged contact with the skin will not exceed 0.5 micrograms per square centimetre per week.
Scope
This European Standard specifies a method for simulating the release of nickel from consumer items in direct and prolonged contact with the skin in order to determine whether such items release nickel at a rate greater than 0.5 µg/cm²/week.
Principle
The item to be tested for nickel release is placed in an artificial sweat test solution for 1 week. The concentration of dissolved nickel in the solution is determined by atomic absorption spectrometry or other appropriate analytical methodology. The nickel release is expressed in micrograms per square centimetre per week (µg/cm²/week).
Test Report
The test report for each determination shall include at least the following information:

identification of the sample including source, date of receipt, form;
sampling procedure;
the reference and a short description of the method used;
description of the sample area including the size of the sample area expressed in square centimetres;
the volume of test solution used;
the nickel release and its adjusted analytical result;
if relevant, deviations from this standard method;
any unusual features observed during the determination;
starting and completion dates of test;
identification of laboratory carrying out the analysis; and
signature of laboratory manager and operator.
