This part of ISO 10136 specifies an analytical pro-cedure, using molecular absorption spectrometry, for measuring the concentrations of boron, expressed as its oxide (B2O3), 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), or neutral glass as defined in ISO 4802[3][4], tableware and kitchenware. The extract solution may be ob-tained 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.
