Please enter 20 to characters to contact this supplier! Very versatile the DTC covers an extremely wide conductivity range using three different stack modules easily interchangeable by the user. Solids, pastes, liquids, thin films.
Link to Active This link will always route to the current Active version of the standard. The thermal conductivity of the sample can be evaluated using the measure of temperature difference of the sample along with the heat flux transducer output.
The additional values are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. A sample material to be tested is placed in a compressive load between two polished metal surfaces of varying temperatures. Do you have a question you’d like to ask regarding this article? Reproducible sample load for accurate awtm The test specimen is held under a user-selectable compressive load between two polished metal surfaces.

In this interview, AZoM talks to Dr. This test method is easy, fast, repeatable. Recommended Quality Verified Suppliers.
Serve Real Instruments Co. Simple, fast, accurate, and reasonably-priced DTC 25 is the ideal instrument for QC and contract laboratories. In addition, significant attention has been paid to ensure that the thermal resistance of contacting surfaces is minimized and reproducible. The specimen is placed in the thermal conductivity equipment at a customer specified temperature and a compressive load of 40 PSI 0.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Composite plates made of unsaturated polyester resin and unidirectional glass fibers were fabricated by injection to validate the methodology.
Numerical simulations were performed to determine the optimal configuration of the heating system to ensure a unidirectional heat transfer in the composite sample.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. From Ducom 8 Nov Private Question to Supplier. I would like your verified suppliers matching service! Using this software, the thermal conductivity of the sample is automatically computed upon entering the data obtained from the digital display of the instrument.
Thermal equilibrium is obtained.
It suited to analyze a variety of materials, including polymers, ceramics, composites, glasses, rubbers, sstm metals, and other materials ranging from low to medium thermal conductivity.

Cancel reply to comment. Simple, Efficient, Economical The DTC astn completely self-contained and requires no additional instrumentation for the measurement of a wide range of low-to-mid thermal conductivity.
An optional software is available to download, archive and print thermal conductivity results. The test method is utilized for solids of a representative thickness. Xstm August 14, A body is considered homogeneous when the property to be measured is found to be independent of specimen dimensions. This information has been sourced, reviewed and adapted from materials provided by TA Instruments.
Because of its simple operation and short cycle time, the DTC is ideally suited for quality control and screening of materials. An axial temperature gradient is generated in the pile with the flow of heat from the upper surface to the lower surface via the sample. Polymers can be tested through the melt using special containment cells.
