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 F963, 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 F963 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 Appendix X1.

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.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
