Performance Rating Window and Door products included in this standard are designated by a four-part code which includes product type, performance class, performance grade and maximum size tested. The format for product designation is:

Product Designation System HS - LC 25 48x76

Product Type Horizontal Slider

Performance Class Light Commercial

Performance Grade Design Pressure=25 psf

Maximum Size Tested Width x Height

Note: an asterisk (*) added to the performance grade indicates that the size tested for the optional performance grade was smaller than the minimum test size for the original product type and class. 12

Product Type Window and Door products covered in this standard are as follows: AP = Awning, Hopper, Projected Window BW = Basement Window C = Casement Windows DA = Dual Action Windows DA-HGD = Dual Action Hinged Glass Doors F = Fixed Windows GH = Greenhouse Windows H = Hung Windows (Single, Double, Triple) HE = Hinged Egress Windows

HGD = Hinged Glass Doors HP = Horizontally Pivoted Windows HS = Horizontal Sliding Windows J = Jalousie Windows JA = Jal-Awning Windows SHW =Side Hinged Inswinging Windows SGD = Sliding Glass Doors TA = Tropical Awning Windows TH = Top Hinged Windows VP = Vertically Pivoted Windows VS = Vertical Sliding Windows

Each product type and class requires minimum test sizes for entry into the product class. 14

Performance Class Window and Door products covered by this standard are divided into five performance classes as follows:

RR = = Residential Residential LC LC = = Light Light Commercial Commercial CC = = Commercial Commercial HC HC = = Heavy Heavy Commercial Commercial AW AW = = Architectural Architectural 15

Performance Grade Products are designated by the design pressure for which they have been tested in pounds per square foot. The structural test pressure is 1.5 times the design pressure. Each product performance class shall have a minimum performance grade as follows:

R LC C HC AW

= 15 psf (720 Pa) = 25 psf (1200 Pa) = 30 psf (1440 Pa) = 40 psf (1920 Pa) = 40 psf (1920 Pa)

In addition, products may be tested to optional performance grades higher than the minimum grade in increments of 5 psf (240 Pa). 16

Section 4.0 Optional Performance Grades

Under “Optional Performance Grades”, manufacturers can test their products to exceed the minimum performance requirements outlined in sections 1.0 and 2.0, for both design load and water test pressure.

21

Glass and Glazing Materials Glazing specifications are included in the standard. Annealed glass installed in windows shall meet ASTM C 1036. Safety glazing materials where used, shall conform to ANSI Z97.1 or CPSC 16 CFR 1201. Tempered glass, where used, shall conform to ASTM C 1048 (Kind FT). Safety glazing shall be furnished on glass doors. Sealed insulating glass, where used, shall conform to ASTM E 774 level C or higher (Level A for AW products). Glass furnished by the manufacturer shall meet or exceed the values given in ASTM E 1300 for the design pressure rating of the product. Allowable pressures from the graphs are allowed to be increased as noted for the use of heat strengthened, fully tempered or sealed insulating glass and are required to be decreased as noted for the use of laminated glass. 22

Conformance Tests Unless otherwise stipulated in this specification, windows and doors submitted for tests under sections 2 and 4 shall contain glazing intended for use in the product. For products with glass infill, the glass type shall be the minimum strength required for a given load and size based on ASTM E 1300, with the exception that frame or sash deflections, where not specified in the document, are not limited to the glass edge dimension divided by 175. Products tested with a specific glass type shall qualify products of a smaller size manufactured with a different glass type provided the glass conforms to ASTM E 1300, as referenced above. Products tested with plastic materials shall not qualify glass glazing materials, nor products tested with glass qualify plastic glazing materials. Products tested with sealed insulating glass shall not qualify single glazed products. 23

Field Testing

Quality Assurance Photos courtesy Architectural Testing, Inc. 24

Project Specifications Not all projects have a field quality control section listed in the specifications. In these cases the laboratory performance requirements are usually referenced and used to develop an on-site test program. If the quantity, size and other details of the field test specimens are not listed in the project specification, standards/specifications such as AAMA are normally utilized. Typically the field quality control section of the project specification will either reference an AAMA field test standard or list specific performance requirements in addition to the ASTM test methods that are required. 25

Standards/Specifications: AAMA Short Form Field Testing Specifications are provided for both 502 and 503 AAMA Field Testing Specifications are intended for testing of installed new fenestration Test chambers may be installed on the outside (positive pressure) or inside (negative pressure) of the building Field Testing to be conducted by an AAMAaccredited lab; AAMA 204-98, Guidelines for

AAMA Accreditation of Independent Laboratories Performing On-Site Testing of Fenestration Products 28

AAMA 502-02 Test Methods A and B differ in the location of the chamber perimeter lines and therefore, whether or not the perimeter seals, subframe/receptor system, and frame corners are tested under pressure. Test Method A is the default. Non-structural interior trim may have to be removed to check for leaks Optional Sill Dam Test checks for corner leaks 29

AAMA 502-02 Method B Test Method B tests the product and its installation in the rough opening. Chamber is applied to the wall construction. If interior wall materials have been installed, they must be removed at the test area to provide visual access to check for leaks

32

33

AAMA 502-02 Performance Criteria Allows 1.5 times the 101/I.S.2 specified maximum air leakage rate. A ‘blank’ may be used to identify and subtract extraneous air; e.g., through sides of the frame Water penetration resistance is tested at 2/3 of the 101/I.S.2 specified pressure. Cyclic pressure is used for R, LC, & C products; Uniform pressure for AW; both for HC. Alternate air leakage & water penetration resistance requirements may be specified 34

Interior Test Chamber AAMA 502-02 Method B 36

AAMA 503-03 Contract should specify testing area, and whether perimeter seals are to be included. Otherwise, the specimen should include perimeter seals, typical splices, frame intersections, and, if applicable, at least two entire vision lites and two entire spandrel lites containing an intermediate vertical and an intermediate horizontal. Field air leakage tests are only recommended for discrete “punched opening” curtain walls, storefronts, and sloped glazing elevations. Not recommended for a portion of a continuous system due to problems with compartmentalization and identification of extraneous air leakage. 37

AAMA 503-03 Windows and sliding glass doors included within the specimen are tested per AAMA 502 Water penetration is tested per E 1105, applying uniform (not cyclic) pressure Timing is critical; sheetrock, trim, insulation, etc. that would affect chamber attachment or visual inspection must be removed if installed If air leakage is to be tested, it must be performed before water penetration testing 38

AAMA 503-03 Test Setup

39

AAMA 503-03 Performance Criteria Air leakage test performed at a minimum of 1.57 psf and not to exceed 6.24 psf. Allows 1.5 times the project specification rate or 0.09 cfm/ft2 whichever is greater Water penetration test shall be conducted at twothirds of the specified project water test pressure, but not less than 6.24 psf Alternate air leakage & water penetration resistance requirements may be specified
