This European standard specifies a process for determination of mercury in cosmetics by means of cold vapour atomic absorption (AAS) with a prior pressure digestion. This process was validated by means of an interlaboratory test according to ISO 5725-2 [6] using e.g. lipstick, body lotion, toothpaste and eyeshadow, with a mercury concentration in the range of 0,110 mg/kg to 5,84 mg/kg. Statistical characteristics regarding this interlaboratory test are provided in Annex A, Table A.1. This standard has been developed in parallel with ISO 23674. Knowing this, an interlaboratory test using either one or the other method was performed on same tailor-made cosmetic products in order to establish that both methods fulfilled the same requirements (see Annex B).
