The National Fenestration Rating Council Board of Directors approved four NFRC documents, which are now open for public review according to the American National Standards Institute’s process. The public review and comment period are scheduled to run from May 5 to June 19.
The four documents to be submitted for public review, comment and the full ANSI consensus process are:
- NFRC 100: Procedure for Determining Fenestration Product U-factors
- NFRC 200: Procedure for Determining Fenestration Product Solar Heat Gain Coefficient and Visible Transmittance at Normal Incidence
- NFRC 202: Procedure for Determining Translucent Fenestration Product Visible Transmittance at Normal Incidence
- NFRC 500: Procedure for Determining Fenestration Product Condensation Index Ratings
The announcement that these documents are open to public comment appeared in Standards Action on May 5, marking the beginning of the open public comment period. With the documents being available electronically, the comment period is 45 days, ending on June 19. All changes subject to public review have been previously balloted and approved by NFRC membership and the NFRC Board of Directors.
The documents up for review (with changes from the previous version shown in underline/strikethrough format) and additional details are available on the NFRC Documents in Public Review page.
