New Standard from Last Update.

NATIONAL FOREWORD

This Indian Standard (First Revision) which is identical with ISO 4787 : 2021 ‘Laboratory glass and plastic ware - Volumetric instruments - Methods for testing of capacity and for use’ 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 document provides methods for the testing, calibration and use of volumetric instruments made from glass and plastic in order to obtain the best accuracy in use.

The standards for the individual volumetric instruments include clauses on the specification of capacity (volume); these clauses describe the method of manipulation in sufficient detail to determine the capacity without ambiguity. This document contains supplementary information.
