Specifies an analytical procedure (with the use of molecular absorption spectrometry) for measuring the concentrations of silicon released into extract solutions during hydrolytic resistance test procedures. Coverage includes definitions, reagents, apparatus and procedure.

This part of ISO 10136 specifies an analytical procedure, using molecular absorption spectrometry, for measuring the concentrations of silicon, expressed as silicon dioxide or silica (SiO2), released into extract solutions during hydrolytic resistance test procedures.

This part of ISO 10136 applies to the analysis of extract 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), neutral glass, or soda-lime-silica glass as defined in ISO 4802[3][4], food and drink packaging ware, tableware 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 addition, it may be applied to the extract solutions produced by any method for measuring the hydrolytic resistance of glass or glassware.
