FOREWORD The National Fenestration Rating Council, Incorporated (NFRC) develops and operates a uniform rating system for energy and energy-relate

6、d performance of fenestration 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, are mandatory ratings for inclusion on label certificates, and are sup

7、plemented by procedures for voluntary ratings of products for Air Leakage (AL), Ventilation Rating (VR), and Condensation Resistance. Together these rating procedures, as set forth in documents published by NFRC, are known as the NFRC Rating System. The NFRC Rating System employs computer simulation

8、 and physical testing by NFRC-accredited laboratories to establish energy and related performance ratings for fenestration product types. The NFRC Rating System is reinforced by a certification program under which NFRC-licensed responsible parties claiming NFRC product certification shall label and

9、certify fenestration 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). The requirements of the rating, certification, and labeling programs (Certification Programs) ar

10、e 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) Product Certification Program (CMA-PCP). Through the Certification Programs and the most recent ver

11、sions 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 Program (LAP). The IA licensing program (IA Program), as set forth in NFRC 702 Certification Agen

12、cy 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 400-2017E0A0 Page iv 2013. National Fenestration Rating Council Incorporated (NFRC). All rights reserved. NFRC intends to ens

13、ure 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 to participate in the Certification Programs, a Manufacturer/Responsible Party shall rate a pr

14、oduct 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 products for U-factor, SHGC, VT, AL, condensation resistance, or any other procedure adopted by NF

15、RC, 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 from a laboratory that has been accredited by NFRC in accordance with the requirements of the

16、 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 inspections for quality assurance in accordance with the requirements of the NFRC 702, and iss

17、ue a product Certification Authorization Report (CAR) or approve for issuance an NFRC Label Certificate for site-built or CMA products and attachment products. The IA is also responsible for the investigation of potential violations (prohibited activities) as set forth in the NFRC 707 Compliance and

18、 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 considered to be NFRC-certified. NFRC maintains a Certified Products Directory (CPD), listing product

19、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 accordance with the NFRC 700 (PCP), the NFRC 701 (LAP), the NFRC 702 (CAP), the NFRC 705 (CMA-PCP

20、), 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. NFRC owns all rights in and to each of the NFRC 700, NFRC 701, NFRC 702, NFRC 705, NFRC 707, NFRC 7

DISCLAIMER NFRC certification is the authorized act of a Manufacturer/Responsible Party in: (a) labeling a fenestration or

25、 related attachment product with an NFRC Permanent Label and NFRC Temporary Label, or (b) generating a site built or CMA label certificate, either of which bears one or more energy performance ratings reported by NFRC-accredited simulation and testing laboratories and authorized for certification by

26、 an NFRC-licensed IA. Each of these participants acts independently to report, authorize certification, and certify the energy-related ratings of fenestration and related attachment products. NFRC does not certify a product and certification does not constitute a warranty of NFRC regarding any chara

27、cteristic of a fenestration or fenestration-related attachment product. Certification is not an endorsement of or recommendation for any product or product line or any attribute of a product or product line. NFRC is not a merchant in the business of selling fenestration products or fenestration-rela

28、ted products, and therefore cannot warrant products as to their merchantability or fitness for a particular use. NFRC THEREFORE DISCLAIMS ANY AND ALL LIABILITY THAT MAY ARISE FROM OR IN CONNECTION WITH SERVICES PROVIDED BY, DECISIONS MADE BY OR REPORTS OR CERTIFICATIONS ISSUED OR GRANTED BY ANY NFRC

29、-ACCREDITED LABORATORY, NFRC-LICENSED IA OR ANY PRODUCT MANUFACTURER/ RESPONSIBLE PARTY; RELIANCE ON ANY NFRC PRODUCT DESCRIPTION, SPECIFICATION, RATING, TEST OR CERTIFICATION, WHETHER APPEARING IN A REPORT, A PRODUCT CERTIFICATION AUTHORIZATION OR A PRINTED OR ELECTRONIC DIRECTORY, OR ON A LABEL, O

PURPOSE To specify a procedure for determining fenestration product air leakage. 2. SCOPE This procedure defines the criteria for testing fenestration air leakage rates to the requireme

33、nts and guidelines as established by the NFRC. Many of the criteria are referenced from other ASTM standards and NFRC 100 1. Issues of test pressures, leakage mode, test size, and test temperatures are based on currently acceptable and recognized industry practices for air leakage testing of fenestr

34、ation. Within this procedure the North American Fenestration Standard/Specification for windows, doors, and skylights (NAFS) 2, 3, 8 or the Florida Building Code Testing Application Standard (TAS) 202 7 can alternately be used to report product air leakage provided all conditions in Section 4 are me

35、t. This procedure is applicable to fixed and operable fenestration products. Air leakage rates for a given fenestration product may vary depending on quality control, environmental factors (temperature, barometric, pressure, humidity, etc.), usage-stresses, operating style differences, long term dur

36、ability, variable installation methods, and material/design selection. This procedure does not address any of these issues. The air leakage rates obtained from this procedure are intended primarily for product comparison purposes. 3. DEFINITIONS Reference NFRC 600: Glossary and Terminology 4. 4. TES

37、T CRITERIA ASTM E283 5 shall be the only method used to measure product air leakage rates (see Note 1). The following conditions shall apply: A. The differential static test pressure shall be 75 pascals (1.57 psf), applied to the test specimen so as to cause the air leakage to occur at the specimens

38、 interior side. Any type of chamber may be used; i. A differential static pressure of 300 pascals (6.24 psf) shall be acceptable if the North American Fenestration Standards (NAFS) References 2, 3, 8 is used for products obtaining an HC or AW rating. ANSI/NFRC 400-2017E0A0 Page 2 2013. National Fene

39、stration Rating Council Incorporated (NFRC). All rights reserved. B. The measured air leakage shall be corrected to standard test conditions per ASTM E283; C. The rate of air leakage for all window fenestration products shall be reported as l/sm2 (cfm/ft2); D. The specimen test size shall not be les

40、s than one of the following: i. The Model Size per NFRC 100, Table 4-3 1; or, ii. The NAFS Class R Gateway Size. Exception: If the largest production size does not meet Section 4.D (i) or (ii) then use the standard production size with the least deviation from the Model Size as defined in NFRC 100,

41、Section 4.6.1 E. Product lines cannot be grouped for air leakage testing; F. The leakage rate shall be measured to one decimal place in l/sm2 (i.e., #.#); G. Operating force shall be measured and recorded per NAFS for all operable fenestration products. The specimen shall be operated per ASTM E283 p

42、rior to an air leakage test being performed. No adjustments shall be made to the specimen between conducting the operating force and air leakage tests; and H. Once the test specimen has been received by the laboratory, no material or component modifications to the product shall be performed by the l

43、aboratory without written instructions from the manufacturer. The laboratory shall report all adjustments and modifications that were made to the specimen to obtain the reported air leakage rates. Note 1: This procedure references the use of ASTM E283 as the only method for measuring individual prod

44、uct air leakage rates. ASTM E283 is a laboratory test method that has been used for many years to measure air leakage rates under controlled conditions. Since the NFRC 400 procedure measures air leakage rates at only one pressure differential, it is best used to compare the relative performance of f

45、enestration products. It does not directly provide information on how a product will perform in a specific building application at field conditions. 5. REPORT Report results per NFRC 701.06 6.
