|Submit Thermophysical Properties|
The thermophysical properties of materials used in NFRC rating procedures are obtained either from appendices A and B in NFRC 101, or by physical measurements for inclusion in appendix C. Appendix C inclusion requires a peer review process as defined in the NFRC 101. Once the properties are reviewed successfully, they are placed in NFRC 101 appendix C in and can be used by the submitter or by a party authorized by the submitter.
Three types of thermophysical properties can be obtained using this process;
Anyone wishing to submit thermophysical properties of materials for NFRC approval shall:
Note: Emissivity, solar absorptance, and other solar-optical properties of transparent glazing materials are determined using Submit Optical Properties.
Any submitter may also request that the material be added to NFRC 101 appendix A or B, if it is a generic material. The submitter is responsible for proposing the representative generic value for such material(s) and providing sufficient references or other justification. The Thermophysical Properties Peer Review Group will then rule on the request. NFRC publishes addenda to NFRC 101 each time a new material is approved.
