Fibre Chemistry Aims and scope

Conclusions

A procedure for determining sulfuric acid concentration by potentiometric titration to an assigned pH value has been developed.

Metrological certification of this procedure as compared with the umpire method has been performed.

The procedure conforms to normative requirements in accuracy characteristics and is recommended for inclusion in the branch standard.
