适用范围：This part of ISO 10136 specifies an analytical pro-cedure, using molecular absorption spectrometry and flame atomic absorption spectrometry, for measuring the concentrations of iron, expressed as iron(lll) oxide (Fe2O3), released into extract solutions during hydrolytic resistance test procedures. This part of ISO 10136 applies to the analysis of ex-tract solutions obtained from any kind of glass or glassware, including laboratory and pharmaceutical ware made, for example, from borosilicate glass (such as borosilicate glass 3.3 according to ISO 3585), neu-tral glass, or soda-lime-silica glass as defined in ISO 4802[3][4], food and drink packaging ware, table-ware and kitchenware. The extract solution may be obtained from glass articles, for example according to ISO 4802 or from glass as material, for example when tested according to ISO 719[1] or ISO 720[2]. In ad-dition, it may be applied to the extract solutions pro-duced by any method for measuring the hydrolytic resistance of glass or glassware.
