DINEN 1811:2015-10EN 1811:2011+A1:2015 (E) 5 Introduction Adverse skin reaction to nickel has been know

35、n for many decades. Nickel is the most frequent cause of contact allergy in Europe, and 10 % to 20 % of the patch tested female population and 1 % to 3 % of the patch tested male population are allergic to nickel. Skin absorption of nickel ions, which are released from some nickel-containing materia

36、ls which are inserted into pierced ears or other pierced parts of the human body or which are in direct and prolonged contact with the skin, causes sensitisation. Further exposure to soluble nickel salts results in allergic contact dermatitis. It is known that sensitisation to nickel requires higher

37、 exposure levels than does the elicitation in already sensitised individuals. There is a large variation in the degree of sensitivity to nickel between individuals. This widespread health problem has forced the introduction of a number of measures designed to reduce its prevalence. These measures in

38、clude the requirements of this standard which provides an in-vitro chemical test that correlates as far as possible with the variable human biological reactions that occur when metallic articles containing nickel are in direct and prolonged contact with the skin and pierced parts of the body. The st

39、andard provides a measure of the amount of nickel release from an article immersed for one week in artificial sweat. The standard also describes the preparation of a quality control material intended to assist a laboratory in achieving an acceptable precision. Clinical patch-testing of a small selec

40、tion of nickel-containing alloys and coatings on nickel-sensitized persons indicates that high and low results achieved with the present analytical method correspond closely with patch-test reactivity. Moreover, a nickel migration limit of 0,5 g/cm2/week for articles intended to come into direct and

41、 prolonged contact with the skin and a nickel migration limit of less than 0,2 g/cm2/week for all post piercing assemblies inserted into pierced ears and other pierced parts of the human body has been set in Commission Regulation (EC) No 1907/2006 of the European Parliament and the Council (in the c

42、urrent version). DIN EN 1811:2015-10 EN 1811:2011+A1:2015 (E) 6 1 Scope This European Standard specifies a method for simulating the release of nickel from all post assemblies which are inserted into pierced ears and other pierced parts of the human body and articles intended to come into direct and

43、 prolonged contact with the skin in order to determine whether such articles are in compliance with No. 27 Annex XVII of Regulation (EC) No 1907/2006 of the European Parliament and of the Council (REACH). Spectacle frames and sunglasses are excluded from the scope of this European Standard. NOTE Spe

44、ctacle frames and sunglasses are subject to the requirements of EN 16128:2011 which provides an unchanged re-publication of the technical requirements that had previously been specified in EN 1811:1998, but restricted in scope to apply only to spectacle frames and sunglasses. 2 Normative references

The concentration of dissolved nickel in the solution is determined by an appropriate analytical method, for example inductively-coupled plasma spectrometry. The nickel release is expressed in micrograms per square centimetre per week (
