Reference value for traceability dissemination
� Problem
Measurement uncertainty: ±1°C.
In medicine, the requirement is ±0,1°C.
� Solution
� Research (2002-2004): the required uncertainty achieved
� PhD
� Patent
� 3 scientific publications
� Participation in expert group for drafting international ISO standard for thermometers in medicine.

Reference value for a PT
� Problem
�According to new legislation, conformity assessment of
50% of all articles from precious metal alloys is done by
private laboratories
� MIRS has overall responsibility
� Solution
� PT scheme has been set up
� MIRS is providing a reference value for PT

Reference value for internal quality control
� Problem
Price of titanium(IV) oxide white
pigment depends on its properties,
which are regularly measured and
globaly compared. There is no
adequate internal quality control
material available.

Reference value for internal quality control
� Solution
� Study of homogeneity and stability
� Establishing of reference values for various parameters of
titanium(IV) oxide white pigment sample and evaluation of
their measurement uncertainties

Raising competence in laboratories
e.g. for mass measurements:
�Calibration of weights
�Calibration of weighing instruments
�Verification of weighing instruments
�Measurement uncertainty
�Quality management system
�Problem:
A lot of measurements, which used to be done by a metrology
institute, are now on-going in private and public laboratories

Raising competence in laboratories
Training methods:
�International standards and guidelines
�Laboratory work
�Hands-on training
�On-field work
�Discusion
�Solution:
�Organising tailor-made training courses for experts from
