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. (Reference: Table

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.

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 (inches) 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)
