It co

16、nsists of 12 Clauses and an Annex.Clause 1 outlines the Scope of this Standard/Specification.Clause 2 provides a listing of all other Standards referenced in this Standard/Specification.Clause 3 contains a list of definitions used in this Standard/Specification.Clause 4 provides an explanation of th

These are called “Product Sections” since, for convenience of use and updating, they

19、 are based on product characteristics. Products should meet both the general requirements of this Standard/Specification and these specific requirements. American Architectural Manufacturers Association Window (b) water penetration resistance;(c) air leakage;(d) operating force (where appropriate);

21、indows, and unit skylights. These include requirements for glazing, sash, panel, leaf, and frame materials.Clause 11 presents the component requirements applicable to all windows, doors, SSPs, TDDs, roof windows, and unit skylights. These include requirements for hardware, fasteners, weatherstrippin

22、g, insect screens, reinforcing members, sealants, coatings and finishes, adhesives, integral ventilating systems/devices, between-glass shades, setting blocks, attachments, and preservatives.Clause 12 presents the specific product performance requirements appropriate to each type of window, door, SS

23、P, TDD, roof window, and unit skylight. These include requirements for test specimens, such as product tolerance and qualifying the test specimen for variations of design and assembly.Table 12.2 contains a summary of all performance requirements included in this Standard/Specification. These require

24、ments are presented in tabular format for easy use by the specifier and include references to the applicable Clauses of this Standard/Specification, organized by product type.Annex A provides contact information for the standards development organizations listed in Clause 2.0.2 Performance Classes a

25、nd Grades0.2.1 GeneralThis Standard/Specification defines requirements for four Performance Classes. The Performance Classes are designated R, LC, CW, and AW for windows, doors, and secondary storm products (SSPs). Skylights, roof windows, and TDDs are not identified with a Performance Class, but ar

26、e treated in a way similar to specialty products. This classification system provides for several levels of performance. It is important to note that although general suggestions for use are specified in Items (a) to (d), product selection is always based on the performance requirements of the parti

27、cular project and not solely on these suggestions. The Performance Class ratings should be regarded as an indication of the level of performance, with the least stringent requirements established for the R Performance Class and the most stringent for the AW Performance Class. The following descripti

28、ons can be used as a general guide in helping to determine which class is likely best suited for a particular application:(a) R: commonly used in one- and two-family dwellings.(b) LC: commonly used in low-rise and mid-rise multi-family dwellings and other buildings where larger sizes and higher load

29、ing requirements are expected.(c) CW: commonly used in low-rise and mid-rise buildings where larger sizes, higher loading requirements, limits on deflection, and heavy use are expected.(d) AW: commonly used in high-rise and mid-rise buildings to meet increased loading requirements and limits on defl

30、ection, and in buildings where frequent and extreme use of the fenestration products is expected.Minimum Performance Grades (PG), design pressures (DP), structural test pressures (STP), and water penetration resistance test pressures for all Performance Classes are specified in Table 12.2.Table 0.1

38、 to specified wind load.0.2.4.2Current model building codes require windows, doors, TDDs, roof windows, and unit skylights to be designed and installed to sustain prescribed loads on components and cladding. These loads are affected by a number of factors, including(a) geographic wind speed;(b) buil

39、ding exposure;(c) building height;(d) location of the window, door, TDD, roof window, or unit skylight on the building; and(e) snow load.0.2.4.3Geographic wind speed will affect the overall value of the wind pressure that the window, door, TDD, roof window, or unit skylight will be anticipated to su

40、stain. Positive and negative wind pressures will be increased or decreased with geographic wind speed.0.2.4.4Building exposure will also affect the overall value of the wind pressure, and in addition can affect local conditions across the buildings surface by an increased or decreased presence of wi

41、nd turbulence. Turbulence is caused when the wind is forced to change direction by an object in its path. The building exposure can affect the amount of turbulence based on the number of buildings, objects, or topography immediately surrounding the building. Wind speed increases greatly as height ab

42、ove mean ground level increases, increasing the anticipated wind pressure that the building will be expected to sustain. Exposure also influences the factored snow load that the building surfaces need to resist.0.2.4.5Location of the window, door, SSP, TDD, roof window, or unit skylight on the build

43、ing has the potential of significantly affecting the anticipated wind pressure on a single window, door, SSP, TDD, roof window, or unit skylight. Wind flow patterns are affected by building shape. Wind encountering a building is redirected to flow around and over the building. Wind traveling around

44、the corners of the building separates from the building surface, causing turbulence and local negative structural pressures. Location can also influence the factored drifting or sliding snow loads that the building surfaces need to resist.0.2.4.6Wind loads on components and cladding are not the same

45、 as main wind force-resisting-system (building structure) wind loads, in that components and cladding experience localized higher pressure (peak load) in a relatively small area. Wind gusts can cause short-duration peak pressures on a small area of the buildings surface. The wind pressure calculatio

46、n for components and cladding loads accounts for these American Architectural Manufacturers Association Window the negative wind load will almost always be higher than the positive. As such, codes and building authorities that reference ASCE/SEI 7 or other means of determining positive and negative

47、loads require the product to meet both the positive and negative design constraints of the application. This Standard/Specification incorporates a system for rating windows, doors, SSPs, TDDs, roof windows, and unit skylights with an appropriate separate positive and negative design pressure (DP).No

48、tes: (1) Where snow load is significant, it is not unusual for the positive load to be much higher than the negative.(2) Positive or negative DP refers to “allowable stress design” (as opposed to “strength design”), as referenced in ASCE/SEI7.0.2.4.10A maximum deflection limit of L/175 (where L is t

Generally, improved water penetration resistance and air leakage requirements have been specified for AW products compared to those specified for CW products. AW products are also required to pass the life cycle testing in AAMA 910.0.2.5 Water penetration resistance testing and performance0.2.5.1 GeneralClause 9 specifies that, except for side-hinged door systems, the minimum water penetration resistance test
