13、 Standard is to specify the unified test method to be applicable for the purpose of confirming the safety to human and environment when the slags such as steel slag, non-ferrous slag, waste molten slag are effectively utilized. 1 Scope This Standard specifies the test method for leached chemicals co
14、ntent carried out for evaluating its safety when there is the possibility in which the slags such as steel slag, non-ferrous slag, waste molten slag and the products (slags) such as the roadbed materials, asphaltic products, concrete products are directly ingested to human. The content called herein
15、 means the extractable amount by using 1 mol/L of hydrochloric acid, etc. and the objective chemical substance of this test method for content is the inorganic matter such as lead, cadmium, mercury, fluorine, boron. 2 Normative references The following standards contain provisions which, through ref
