New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard which is identical with ISO 3585 : 1998 ‘Borosilicate glass 3.3 - Properties’ issued by the International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendation of the Glass, Glassware and Laboratoryware Sectional Committee and approval of the Chemical Division Council.

This standard specifies the characteristics of a type of glass designated “borosilicate glass 3.3” used for the construction of laboratory glassware, glass plant, pipeline and fittings.

It is the purpose of this standard to define and facilitate the identification of a type of glass appropriate for laboratory glassware, glass plant, pipeline and fittings.

The glass used for this application, referred to as “borosilicate glass 3.3”, 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 test methods to which reference is made in this standard.
