| 1 . PREFACE
This edition of the NFRC Condensation Resistance procedure includes information from ASTM C 1199, ASTM E 1423, NFRC round robin testing data, and technical interpretations by NFRC. The Condensation Resistance procedure includes a Simulation Method and a Test Method.
The NFRC Simulation Method is presented in Section 4. The Simulation Method is based upon the NFRC-approved software tools and is to be used in conjunction with NFRC 100 and the NFRC Simulation Manual.
The Test Method references NFRC 102 which contains many aspect of ASTM C 1199, as well as modifications adopted by NFRC.
The Test Method has been developed to be a supplement to the Simulation Method. Those products that cannot be simulated for Condensation Resistance shall use the test procedure to determine a Condensation Resistance rating. The Test Method replicates, as closely as possible, the Simulation Method for Condensation Resistance, but simulated and tested Condensation Resistance values may not be identical. The simulations are being validated with tested U-Factors, as obtained using the NFRC 100 procedure and not with tested Condensation Resistance values.
This procedure may involve hazardous materials, operations and equipment. This procedure does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this procedure to establish appropriate health and safety practices and to determine the applicability of any regulatory limitations prior to use.
The values stated in metric (SI) units are to be regarded as the standard. The inch-pound (IP) units shown in parenthesis are for reference only. |
