- Abstract
- The low temperature guarded-hot-plate system transferred to NIST-Gaithersburg from NIST-Boulder has been modified, reassembled and evaluated. Preliminary evaluation tests include the measurement of the effective thermal conductivity of a polyurethane (PUR) foam specimen at temperatures from-170 deg C to 30 deg C in a gaseous nitrogen atmosphere. Test results show the temperature dependency of the thermal conductivity expected of rigid PUR foams indicating the system is now operational and ready for final evaluation tests.
