| Abstract | The aim of this work is to develop a guarded hot plate test apparatus for measuring the thermal conductivity of polymer specimen, the size of which is smaller and thicker than that recommended by the ISO and JIS. The authors made three experimental apparatus suitable for the different sizes of specimen 50×50, 100×100 and 200×200 mm2 in area, measured the thermal conductivity of polymer as homogeneous materials, which ranged from 0.2 to 0.6 W·m−1·K−1, and carried out the numerical analysis. The uncertainty for the measurement of the thermal conductivity of the polymer specimens is estimated to be within ±4% using our test apparatus. For the test apparatus suitable for the specimen 50×50 mm2, the gap has an effect on the measurement of the thermal conductivity. In addition, the temperature difference ΔTg of the heat source has a direct influence on the deviation in the thermal conductivity data. The influence of the aspect ratio of the specimen and gap width on the measurement is estimated to be within 0.9% for the specimens 50×50 mm2 used in the present study. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
