COMMISSION ON THERMODYNAMICS
SUBCOMMITTEE ON TRANSPORT PROPERTIES
Number: 122/3/85
Title: Standards of Viscosity and Thermal Conductivity
Coordinator(s): W.A.
Wakeham
Remarks: Commission I.4
Completion Date: 2001 - project terminated
Objective:
The establishment of internationally approved standard reference values
for the transport properties of fluids which may be employed as calibration
data in national or international or industrial laboratories. The
need for the impartiality and objectivity of an international group
of experts is self-evident.
Progress:
Good progress continues to be made. A conflict has arisen over a new
standard reference value for the viscosity of water which is the ultimate
standard for all viscometry. The PTB in Germany have issued a recommendation
without any consultation with any other body. This will require delicate
negotiations since the recommendation is not the same as that planned
by the subcommittee.
Work is proceeding towards the publication of an IUPAC recommendation
and negotiations are in progress to seek agreement with ISO in this
matter. Other publications are in preparation.
