The Benchtop Thermal Conductivity Tester is primarily used for thermal performance analysis of thin solid materials and interface materials, including:

Thin thermally conductive solids

Solid electrical insulation materials

Thermal interface materials, such as thermal grease, silicone grease, and resins

Rubber and elastomer materials

Ceramic materials, including beryllium oxide ceramics and alumina ceramics

Metal and composite substrates, such as aluminum substrates and copper-clad laminates

Standard testing is performed on solid sheet samples. With the use of optional frames and sample cells, powdered and paste materials can also be evaluated. The system is widely applied in universities, research institutes, quality inspection laboratories, and manufacturing facilities for material thermal analysis.

Standards

The instrument complies with and references the following international and national standards:

ASTM D5470-2017

Standard Test Method for Thermal Transmission Properties of Thin Thermally Conductive Solid Electrical Insulation Materials

MIL-I-49456A

Insulation Sheet Materials, Thermally Conductive, Resin-Based and Glass Fiber Reinforced

GB/T 5598-2015

Method for Determination of Thermal Conductivity of Beryllium Oxide Ceramics

GB/T 29313-2017

Test Method for Thermal Conductive Properties of Electrical Insulating Materials
