Significance and Use
This acid extraction method is intended to indicate the solubility of metals from art materials in a weak acid medium. This test method may be useful as one indicator of the amount of metal that is readily available for absorption. It is not meant as a replacement for in vivo tests of absorption of a metal.5
Maximum levels of metal extraction are seen with this test method when results are 250 ppm or less. If results are greater than 250 ppm, the extractant volume should be increased to 100 mL or greater to keep metal levels in the eluate at a level of 5 ppm or less.6
Scope
1.1 This test method covers the extraction of metals from art materials using an extractant that simulates the acid potential of gastric juice. This test method is similar to the extraction method in Specification F 963, except that it requires conducting extraction steps at body temperature instead of at room temperature. The extraction procedure specified in this test method is more rigorous than that noted in Specification F 963 because the procedure causes the extraction of a larger quantity of metal.
1.2 This test method is adapted from the European Toy Safety Standard, EN 71-3:1994 but differs from it in that a solvent extraction step is not required for processing waxes or oil-based products and no specific acceptable metal levels are specified.
1.3 The rational for this test method is discussed in .
1.4 This test method should be used on the art material as a whole and not an art material ingredient. Testing the art material as whole would be expected to give a more accurate estimate of soluble metal than from an extrapolation from testing ingredients.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
