Can some of those be solved by the expertise

available at the national level?

Reference values and

developing new

measurement procedures

Staff competence



4

Reference values and

developing new measurement procedures

Reference values

� Traceability

� External quality assurance

� Internal quality control

Developing new measurement procedures



5

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.

University of Ljubljana, Faculty of Electrical Engineering (MIRS/UL-FE)



6

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



7

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.



8

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

Cinkarna Celje, d.d. , Služba kakovosti&MIRS

IQC, Nordtest report



9

New measurement procedures:

Large upright tanks

�Problem:

�High number of measurements

�Repetitive actions

�Difficult working conditions – inside tank



10

R&R: Automation - Large upright tanks

�Solution:

�Automation of standard ISO 7507-3 measuring method with

LabView and robotised Leica teodolith

�Use of wireless comunication

Robotisation

Wireless

control



11

Competence of staff



12

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



13

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

laboratories as well as for the users of measurement results
