资料摘要：

Introduction In this application note an extruded PS sample certified by NIST has been tested with the Hot Disk Thermal Constants Analyser in order to compare the results with the results obtained with the methods used at other laboratories. By marking each side of each sample with “1” for low side and “2” for upper side, it was possible to test four permutations of the sample set-up and thus it could be possible to analyse possible differences between the upper side and the lower side of the samples as they were manufactured. Since the sample is formed by extrusion,it is assumed that the PS will have a higher density on the bottom side of the sample than the upper side and therefore different thermal properties.

TLS-100

The TLS-100 is a portable thermal conductivity meter used to measure thermal conductivity and thermal resistivity. Perfect for testing the thermal conductivity of soil, polymers, viscous liquids, and other soft materials; as well as testing the thermal conductivity of concrete, rock, stone, or other hard materials. Tests can be performed with the push of a button. The collected data is automatically analyzed and results are displayed immediately.

THW--L2

The Transient Hot Wire (THW-L2) Liquid Thermal Conductivity Meter is an advanced measurement system for direct determination of the thermal conductivity of liquids and pastes in accordance with ASTM D7896. The THW-L2 was designed with speed and operational simplicity in mind. With a single measurement of less than 2 seconds in duration, small volumes of liquids and pastes can be accurately and precisely measured for thermal conductivity. The THW-L2 utilizes a non-stationary measurement approach and rapid test times to limit convective effects for samples with a wide range of viscosities.

HFM brochure

The Heat Flow Meter (HFM) 100 is an easy-to-use rapid technique for the measurement of thermal resistance and thermal conductivity of insulation products, construction materials, packaging, and assemblies. Thermal conductivity is a measure of the ability of a material to conduct heat and can be critical for defining energy efficiency and thermal performance in materials. The Thermtest HFM has been designed and engineered to combine the highest accuracy, repeatability, widest temperature range, and industry leading performance, all at an exceptional value.
