FOREWORD The National Fenestration Rating Council, Incorporated (NFRC) develops and operates a uniform rating sys

6、tem for energy and energy-related performance of fenestration and fenestration attachment products. The Rating System determines the U-factor, Solar Heat Gain Coefficient (SHGC), and Visible Transmittance (VT) of a product, which are mandatory ratings for labeling NFRC-certified products, and are ma

7、ndatory ratings for inclusion on label certificates, and are supplemented by procedures for voluntary ratings of products for Air Leakage (AL) and Condensation Resistance. Together these rating procedures, as set forth in documents published by NFRC, are known as the NFRC Rating System. The NFRC Rat

8、ing System employs computer simulation and physical testing by NFRC-accredited laboratories to establish energy and related performance ratings for fenestration and fenestration attachment product types. The NFRC Rating System is reinforced by a certification program under which NFRC-licensed respon

9、sible parties claiming NFRC product certification shall label and certify fenestration and fenestration attachment products to indicate those energy and related performance ratings, provided the ratings are authorized for certification by an NFRC-licensed Certification and Inspection Agency (IA). Th

10、e requirements of the rating, certification, and labeling programs (Certification Programs) are set forth in the most recent versions of the following as amended, updated, or interpreted from time to time: NFRC 700 Product Certification Program (PCP) NFRC 705 Component Modeling Approach (CMA) Produc

11、t Certification Program (CMA-PCP) and through the Certification Programs and the most recent versions of its companion programs as amended, updated, or interpreted from time to time: The laboratory accreditation program (Accreditation Program), as set forth in the NFRC 701 Laboratory Accreditation P

12、rogram (LAP) The IA licensing program (IA Program), as set forth in NFRC 702 Certification Agency Program (CAP) The CMA Approved Calculation Entity (ACE) licensing program (ACE Program) as set forth in the NFRC 708 Calculation Entity Approval Program (CEAP) ANSI/NFRC 200-2017E0A0 page iv 2013.

13、nal Fenestration Rating Council Incorporated (NFRC). All rights reserved. NFRC intends to ensure the integrity and uniformity of NFRC ratings, certification, and labeling by ensuring that responsible parties, testing and simulation laboratories, and IAs adhere to strict NFRC requirements. In order t

14、o participate in the Certification Programs, a Manufacturer/Responsible Party shall rate a product whose energy and energy-related performance characteristics are to be certified in accordance with mandatory NFRC rating procedures. At present, a Manufacturer/Responsible Party may elect to rate produ

15、cts for U-factor, SHGC, VT, AL, condensation resistance, or any other procedure adopted by NFRC, and to include those ratings on the NFRC temporary label affixed to its products or on the NFRC Label Certificate. U-factor, SHGC and VT, AL, and condensation resistance rating reports shall be obtained

16、from a laboratory that has been accredited by NFRC in accordance with the requirements of the NFRC 701. The rating shall then be reviewed by an IA that has been licensed by NFRC in accordance with the requirements of the NFRC 702. NFRC-licensed IAs review label format and content, conduct in-plant i

17、nspections for quality assurance in accordance with the requirements of the NFRC 702, and issue a product Certification Authorization Report (CAR) and may approve for issuance an NFRC Label Certificate for site-built or CMA products and attachment products. The IA is also responsible for the investi

18、gation of potential violations (prohibited activities) as set forth in the NFRC 707 Compliance and Monitoring Program (CAMP). Products that are labeled with the NFRC Temporary and Permanent Label, or products that are listed on an NFRC Label Certificate in accordance with NFRC requirements, are cons

19、idered to be NFRC-certified. NFRC maintains a Certified Products Directory (CPD), listing product lines and individual products selected by the Manufacturer/Responsible Party for which certification authorization has been granted. NFRC manages the Rating System and regulates the PCP, LAP, and CAP in

20、 accordance with the NFRC 700 (PCP), the NFRC 701 (LAP), the NFRC 702 (CAP), the NFRC 705 (CMA-PCP), and the NFRC 708 (CEAP) procedures, and conducts compliance activities under all these programs as well as the NFRC 707 (CAMP). NFRC continues to develop the Rating System and each of the programs. N

21、FRC owns all rights in and to each of the NFRC 700, NFRC 701, NFRC 702, NFRC 705, NFRC 707, NFRC 708 and each procedure, which is a component of the Rating System, as well as each of its registration marks, trade names, and other intellectual property.

PURPOSE To specify a method for calculating solar heat gain coefficient (SHGC) and visible transmittance (VT) at normal (perpendicular) incidence for fenestration products containing glazings or glazing with applied films

47、, with specular optical properties calculated in accordance with ISO 15099 8 (except where noted) or tested in accordance with NFRC 201 2, NFRC 202 3, and NFRC 203 4. Note: This standard specifies a method for calculating the solar heat gain and visible transmittance from direct solar radiation thro

48、ugh most fenestration products at normal incidence only. This procedure is limited to normal incidence calculations because solar optical data needed for such calculations is typically only available at normal incidence. While solar radiation rarely enters a fenestration product at normal incidence,

49、 SHGC and VT at near normal angles of incidence (less than 30o off normal) are typically very similar to those at normal incidence; for other angles, the SHGC and VT at normal can be used, to first order, as an indicator of the relative magnitude of solar heat gain (SHG) and VT. 2. SCOPE 2.1 Products and Effects Covered The following products and effects are within the scope of NFRC 200 and shall be permitted to be rated in accordance with this procedure. A.
