Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non- governmental, in liaison with SO, also take part in the work. iSO collaborates closely with the International Electrotechnical Commission (lEC)onallmattersofelectrotechnicalstandardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.

This third edition cancels and replaces the second edition (iSO 3585:1991), which has been technically revised. AnnexAof thisInternational Standardisforinformationonly @ISO1998 All rights reserved.

The design of glass components is dependent on the coefficient of mean linear thermal expansion and theultimate tensile strength.Utilization and pressure limitations, but one which will also satisfy certain criteria for chemical resistance. Therefore, the glass, as distinct from the components made from it, shall satisfy certain specified requirements. However, it is accepted that methods of working the glass to achieve the various forms required in practice can affect the properties of the glass. Theglassusedforthisapplication,referredtoas“borosilicateglass3.3",is resistant to both heat and chemicals. Its heat resistance characteristics are defined by the nominal values given for physical properties. Its chemical resistance characteristics are specified within stated limits, using standard The glass is deemed to be satisfactory for the construction of laboratory glassware, glass plant, pipeline and fittings, while for the glass components themselves,otherrelevantInternationalStandardsshouldbeconsulted Where nominal properties are given, they relate, unless otherwise specified, to the range of temperatures of 20 °C to 300 °C. However, this be used freely within this range, nor that they cannot be used outside this range. ili
