Objectives

The aim is to help the user – independent of his knowledge – to find the best way towards the needed property. Depending on his application he has to be guided to the database and if no values are available he will be be guided to the optimum measurement technique and then to the appropriate laboratory.

IKEKick Off meeting 27.01.03WP4

Measurement Techniques IThe relevant criteria to select measurement technique are:

-- sample geometry

-- temperature range

-- type of materials

Main measurement techniques and there representation within EVITherM

-- Stationary techniques (LNE, ZAE),

-- transient techniques (IPSAS, LNE, ZAE): thermal diffusivity, calculation of thermal conductivity

-- micro/nano-scale techniques (INSA),

-- subsecond techniques (IMGC)

-- el. resistivity (IKE, IMGC), calculation of thermal conductivity

-- heat flow (TNO)

-- photo thermal methods for thin film thermal conductivity-measurements

IKEKick Off meeting 27.01.03WP4

Measurement Techniques II

Written standards-collection of national, European, ASTM and international standards

-translation of key-words, titles, etc. to the English language

-publication to the WEB-page (database)

- if necessary: recommendation of the development of new written standards on CEN/ISO-level

Written standards exist for many measurement techniques. An important working point will be the comparison of different existing written standards, with aim of harmonisation

IKEKick Off meeting 27.01.03WP4

Compilation of Data I

Reference MaterialsCollection of existing reference materials, recommendation for qualification of new materials

Compile qualified data for relevant industrial materials

- metals (up to and above melting point),

- ceramics, glasses, carbon based,

- synthetic materials,

- insulation materials

for measurement laboratories:

for the user:

Compilation of Data II

- measurement results,- measurement technique and experimental conditions, - uncertainties,- measurement parameters,- material description,- reference.

Important information to provide complete datasets.

IKEKick Off meeting 27.01.03WP4

Direct Transfer of Properties Data from Laboratories

to the planned EVITherM-DB

• Advantages for suppliers– Publication easier than via scientific journals– Feedback from the user – Reimbursement if data are sold to users

• Advantages for users– Easy access to new data without delay– Improved reliability since review is by experts– Fast contact to the supplier if questions remain
