Water for analytical laboratory use - Specification and test methods

Executive summary

Requirements and test methods for three grades of water for laboratory use for the analysis of inorganic chemicals.

Abstract

This International Standard specifies the requirements and corresponding test methods for three grades of water for laboratory use for the analysis of inorganic chemicals. It is not applicable to water for organic trace analysis, water for the analysis of surface active agents, or water for biological or medical analysis.

The principal changes to this edition of the standard are the following.

a) The single grade of water has been replaced by three grades, of which grade 3 is roughly equivalent to the water specified in the previous edition.

b) Residue on ignition is no longer specified and the requirement (for grade 3 water) for residue on evaporation has been tightened.

c) Electrical conductivity is now measured at at 25 degrees C instead of 20 degrees C, and the requirement for grade 3 water has been changed from 1 mS/m to 0.5 mS/m.

d) The limit for oxidizable matter for grade 3 water has been tightened.

e) Requirements for ammonia content, chloride content and sulphate content are no longer included.

History and related standards

This International Standard is a revision of BS 3978:1966, which is withdrawn.
