Thermal Conductivity and Resistance of Rigid Compressible Insulation

Thermal Conductivity and Resistance of Rigid Compressible Insulation

Date: January 27th

For the measurement of rigid and compressible insulation material, thermal conductivity results calculated from measured thermal resistance is the preferred method.

Homogeneous & Heterogeneous for Transient vs. Steady State Methods

Homogeneous and Heterogeneous for Transient & Steady State Methods

Date: February 9th

When measuring homogeneous or heterogeneous materials, it is important to consider steady-state vs. transient testing methods and how this will influence the measurement of thermal conductivity.

Testing the Thermal Conductivity and Resistivity of Solid Materials using the TLS-100

Thermal Conductivity and Resistivity of Solid Materials using the TLS-100

The transient line source technique can be used for the thermal conductivity and resistivity of solid materials such as concrete, natural stone, and low thermal conductivity ceramics. Dr. Cederkrantz discusses his measurements on the materials using the TLS-100. For in-situ and lab testing using the Transient Line Source: TLS-100.

Measuring the Thermal Conductivity of Fresh and Used Engine Oil

Measuring the Thermal Conductivity of Fresh and Used Engine Oil

Engine oil is an important heat transfer fluid in combustion engines. Overtime, engine oil degrades from heat, pressure, and the collection of debris. Thermtest’s principal scientist, Dr. Sofia Mylona, will investigate the thermal conductivity of new vs. used engine oil and explain her findings in this webinar.

Initial Touch-Times and Steady State Testing of Foams

Touch-Times and Steady State Testing of Foams

As the bedding industry encompasses measurements of comfort for feeling of coolness or warmth, also known as Thermal Effusivity, for both initial touch and steady-state sleeping. This webinar will cover how these comfort factors can be measured and used in design in the bedding industry.
