Thermal Property Standards

Thermal Conductivity Suite Research-Grade Test Materials (RGTMs)

NIST Interlaboratory Study 500102

NIST Thermal Conductivity Suite Research-Grade Test Materials (RGTMs) are provided on a collaborative basis for recipients to contribute thermal property data for Interlaboratory Study 500102. The Interlaboratory Study will provide insights into measurement consensus, assess the agreement between different thermal measurement techniques, and evaluate the potential fitness of purpose as reference materials. Ultimately, Study 500102 will inform the future development of thermal conductivity reference materials, enabling the reliable interlaboratory comparison of data and accelerating the commercialization of materials and devices that rely on critical thermal property measurements. These materials were selected to span the materials and property value ranges relevant to the semiconductor industry using the results from a thermal community survey, thermal measurement vendor instrument specifications, and discussions with technical experts. Every effort was made to achieve maximum compatibility with the diversity of both commercially available and home-built measurement instrumentation, methodologies, and sample requirements.
