Architectural Testing Informational Bulletin #16 March 7, 2005 Topic: Comparison of the new AAMA/WDMA/CSA 101/I.S.2/A440-05 to the previously published industry standards. The purpose of this ATI-TIPS Bulletin is to provide manufacturers, architects, and specifiers with information regarding revisions and additional requirements specified in the recently approved standard for windows, doors, and skylights. The information provided in this Bulletin is not specific to any one manufacturer or product type. This Bulletin is intended to be advisory only and highlights only the significant changes. Reference must be made to the applicable specification for determination of the comprehensive requirements. This TIPS bulletin reviews the following specifications: ANSI/AAMA/NWWDA 101/I.S.2-97, Voluntary Specifications for Aluminum, Vinyl (PVC) and Wood Windows and Glass Doors AAMA/WDMA 101/I.S. 2/NAFS-02, Voluntary Performance Specifications for Windows, Skylights and Glass Doors AAMA/WDMA/CSA 101/I.S. 2/A440-05, Standard/Specification for Windows, Doors and Unit Skylights Important Certification Information The American Architectural Manufacturers Association (AAMA) has officially approved AAMA/WDMA/CSA 101/I.S. 2/A440-05, Standard/Specification for Windows, Doors and Unit Skylights for use in the AAMA Certification Program as of March 1, 2005. Until further notice AAMA will allow certification to all three of the aforementioned documents. The following table and subsequent notes provides a comparison between the AAMA/WDMA/CSA 101/I.S.2/A440-05 and AAMA/WDMA 101/I.S.2-97.

Page 4 of 5 General Comments on the new Specification: 1. Test specimens shall be installed per the manufacturer's instructions. All modifications (alterations) made to the test specimen to obtain the reported values shall be described in the report. 2. Ratings may be indicated in SI (metric) or IP. For example, a double hung R class window may be rated as an H-R15 or H-RM 720. If the rating is desired in SI, the design pressure in pascals is preceded by an "M". 3. Any geometric shape must fit within the rectangular gateway size tested. 4. A fixed unit tested in one orientation does not qualify a reversed unit. 5. Drawings are required for reporting but need not be incorporated in the body of the report. 6. Addition of Specialty Products (SP) as an Operator Type. 7. Sealed insulating glass units shall conform to the requirements of ASTM E 774, Level A; CAN/CGSB 12.8; or ASTM E 2190. Operating Force (Section 5.3.1, Page 47) 1. Operating products are tested to new ASTM 2068 test method. All operating products are required to pass: 1) Maximum force to maintain positions, and 2) maximum force to open. 2. Latches are required to be tested for latch and unlatch force. 3. Side hinged doors must be tested for the force to close and latch. Air Infiltration (Table 6, Page 52) 1. Air Leakage of composite units does not qualify stand alone individual units. Composite Unit Window or glass door unit consisting of two or more sash or panels within a single frame utilizing an integral mullion. 2. Products may be optionally tested to high performance levels for purpose of code, compliance. 3. Canadian (only) air infiltration/exfiltration testing. Levels are permitted to be reported in the secondary designator. Water Penetration (Table 3, Page 4, Page 38 and Page 53) For U.S. applications, the water penetration resistance test pressure for all products is never more than 580 Pa (12 psf). For Canadian applications, the water penetration resistance test pressure for all products is never more than 720 Pa (15 psf). If a manufacturer supplies an exterior full screen and 1/2 screen; test first with one screen then the other. If interior screens are supplied with the test unit they shall be removed prior to testing. For side-hinged door systems, an allowable exception is to test and rate the products for water penetration resistance at an air pressure differential that ranges from 0 Pa (0.0 psf) to any pressure less than the minimum water penetration resistance test pressure required for the indicated performance class and performance grade (design pressure). Side-hinged door systems tested and rated to this exception have a designation identifying the product for "limited water" (LW) performance. This exception is permitted for side-hinged door systems and is not permitted for any other product type.
Page 5 of 5 Uniform Load Deflection (Section 5.3.4.2, Page 55) 1. Load duration shall be 60 seconds for unit skylights and roof windows and 10 seconds for all other products. It should be noted that some jurisdictions require longer than 10 second load durations for all fenestration products. (i.e. 3600/V = 52 seconds for 70 mph wind zone) 2. Deflection shall be measured at design pressure and reported in millimeters () for all products. There is no maximum allowable deflection for R/LC/C windows. 3. Maximum allowable deflection is L/175 for HC and AW. Uniform Load Structural (Section 5.3.4.3, Page 55) 1. Test duration shall be 60 seconds for unit skylights and roof windows and 10 seconds for all other products. a. Permanent set limit <0.4%L for R and LC <0.3%L for C and HC <0.2%L for AW 2. Skylights are tested at 200% of Design Pressure. Note: The minimum structural pressures for unit skylight or roof window (glass or plastic glazing) in Table 25, page 114 are incorrect. Reference Page 27, Table 1 Gateway requirements, for the correct minimum structural test pressures. Forced Entry - FER (Section 5.3.5, Page 55) 1. The insect screen shall be removed prior to FER testing. 2. ASTM F842 or ASTM F588 is mandatory. Where local codes require compliance to other FER specifications, this additional testing is optional. (e.g. CAWM 301 and 300) 3. FER tests for swinging doors is mandatory (AAMA 1304). 4. FER tests for skylights is not mandatory. Deglazing Test (Section 5.3.6.3, Page 57) 1. Maximum movement is limited to 90% of original glazing bite. Side Hinged Doors are required to be tested to Operation/Cycling (Hinged Patio Doors fall under this classification now) (Section 5.3.6.10, Table 18, Page 73), (Figure 29, Page 107 for qualifying configurations) (R) 25,000 cycles (LC) 100,000 cycles (C) 250,000 cycles (HC) 500,000 cycles (AW) 1,000,000 cycles
