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 content in post assemblies which are inserted into pierced ears and other pierced parts of the human body during epithelization of the wound caused by piercing, whether subsequently removed or not, is equal to or less than 0,05 % (m/m).

Scope

This European Standard specifies a method for the determination of nickel in aluminium, titanium, copper, silver, gold and their alloys and in steels by flame atomic absorption spectrophotometry. The method is primarily suitable when the nickel content of a sample lies between 0,03 % and 0,07 % (m/m).

Principle

A test portion is dissolved in an acid medium. The resulting solution is atomized into an air-acetylene flame of the atomic absorption spectrophotometer and the absorption of the resonance energy of nickel (232,0 nm) is compared with that of calibration solutions.

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;
whether any surface layers have been detected;
the result of the nickel release test to detect the presence of surface nickel;
nickel content expressed in micrograms per millilitre (痢/ml);
if relevant, deviations from this standard method;
any unusual features observed during the determination;
date of test;
identification of laboratory carrying out the analysis; and
signatures of laboratory manager and operator.
