1 Scope

This standard specifies inductively coupled plasma optical emission spectrometry (ICP-OES) for the determination of aluminum, antimony, arsenic, antimony, boron, cadmium, chromium in toy materials. A method for the migration of 17 elements of cobalt, copper, lead, manganese, mercury, nickel, selenium, tellurium, tin, and zinc. This standard applies to the determination of 17 kinds of migratory elements in toy materials. This standard applies to the screening and determination of hexavalent chromium, trivalent chromium and organotin in toy materials. This standard applies to Class III toy materials specified in European toy standard EN71-3, including coatings and similar materials, polymers, paper. And cardboard, textile materials, glass, ceramics, metal materials, wood, fiberboard, hardboard, bone and leather.

3 Terms and definitions

The terms and definitions defined in EN71-3 apply to this document.

4 Principle of the method

The sample was transferred to 17 kinds of elements to be tested under specific conditions with a certain concentration of hydrochloric acid, and filtered by inductively coupled plasma emission spectrometry. (ICP-OES) The amount of migration of a particular element in the filtrate was determined.

5 reagents and materials

Unless otherwise specified, only grades of pure and above reagents are used. 5.1 Water, GB/T 6682, Level 2. 5.2 Concentrated hydrochloric acid, the mass fraction is about 37%. 5.3 n-heptane, mass fraction greater than 99%.
