Thermal Conductivity Testing of Solids | Thermtest Inc.

The temperature and output of the heat flux transducer is obtained and recorded. A heating and cooling cycle is applied at the bottom and top surfaces of the sample. Thermal Diffusivity is the output, with known specific heat, thermal conductivity can be calculated.

They helped me by understanding my specific needs of my project and developed a solution for testing my unique samples that I could not have done anywhere else.

Link to Active This link will always route to the current Active version of the standard. The thermal conductivity can be deduced from transient temperature measurements given by thermocouples positioned at three chosen locations along the fibers direction.

Due to copyright restrictions, we are not able to provide copies of standards. E Terminology Relating to Thermophysical Properties. Thermal Conductivity of Solids There are a number of accurate methods for measuring the thermal conductivity of solids. The thickness range e150 0. This is the only standard method specifically designed for testing thermal conductivity of gasket materials. Numerical simulations were performed to determine the optimal configuration of the heating system to ensure a unidirectional heat transfer in the composite sample.


The inverse analysis algorithm is initiated by solving the direct problem defined by adtm one-dimensional transient heat conduction equation using a first estimate of thermal conductivity. E Terminology Relating to Thermophysical Properties. Click here to view more customer comments.

Finally, the evolution of the in-plane composite thermal conductivity can be deduced from the experimental results by the rule of mixture. The wire can also be integrated into cast-able materials like aerogel for intimate contact.

For solid plastic and film materials, multiple adtm For homogeneous opaque solid specimens of a representative thickness, thermal conductivity can be determined see Note 0. For homogeneous opaque solid specimens of a representative thickness, thermal conductivity can be determined see Note 1. Want to know more about our testing services?

Thermal conductivity values are used to measure heat flow through a material. In selecting an appropriate method, there are a number of other considerations, such as thermal conductivity range, surface, sample size, and temperature.


A body is considered homogeneous when the property to be measured is found to be independent of atsm dimensions. The specimen is placed in the thermal conductivity equipment at a customer specified temperature and a compressive load of 40 PSI 0.

Composite plates made of unsaturated polyester resin and unidirectional glass fibers were fabricated by injection to validate the methodology. This standard does not purport to address all of the safety concerns, if any, associated with its use. Historical Version s – view previous versions of standard.

ASTM E1530 – 11(2016)

As the method is absolute, the contact resistance between sensor and sample is able to be removed and the true value e153. Work Item s – proposed revisions of this standard.

In addition, significant attention has been paid to ensure that the thermal resistance of contacting surfaces is minimized and reproducible.
