AAMA Offers Electronic Version of Latest
Fenestration Standard
(SCHAUMBURG,
Ill.) The second edition of AAMA/WDMA/CSA
101/I.S.2/A440, NAFS -- North American
Fenestration Standard/Specification for windows,
doors, and skylights is now available for
electronic download from the American
Architectural Manufacturers Association (AAMA).
According to Ken Brenden, AAMA technical
standards manager, this standard/specification
supersedes the previous edition, published in
2005 under the title AAMA/WDMA/CSA
101/I.S.2/A440-05 Standard/Specification for
windows, doors, and unit skylights and is
expected to be referenced in the 2009 versions
of the ICC Building Codes.
“Significant changes from the previous edition
of this document have been made, including a
reduction in the number of window and door
performance classes from five to four by
elimination of Classes C and HC and the addition
of a new class identified as CW. In addition,
the structural pressure caps have been revised
for the R and LC classes,” per Brenden.
This edition introduces an option whereby a
product is permitted to enter Performance Class
R by testing a specimen of an alternative
minimum test size smaller than the gateway test
size specified in Table 27, provided that the
minimum performance grade (PG) is
correspondingly increased (see Clause 9 for
details).
Relating to
door force-to-latch performance, the
standard/specification now references the
revised AAMA 925-07, Specification for
Determining the Vertical Loading Resistance of
Side-Hinged Door Leaves and excludes any
separate discussion of force-to-latch
requirements.
Clarification of the meaning of, and difference
between, design pressure (DP) and performance
grade (PG) has been made, and the primary
designators for design pressure (DP),
performance grade (PG), and size tested have
been revised.
In addition,
standards for tubular daylighting devices (TDDs)
have been added to the document.
“Previous versions of this
standard/specification are the basis for the
AAMA Gold Label certification program and the
2008 edition was just approved (as an option)
for certification in the program,” says Brenden.
At its
meeting in Indian Wells, Calif., on February 26,
the AAMA Certification Policy Committee
authorized certification to AAMA/WDMA/CSA 101/I.S.
2/A440-08, NAFS -- North American
Fenestration Standard/Specification for windows,
doors, and skylights as of March 1, 2008.
At the same meeting, direction was given to
begin the phase-out of AAMA/NWWDA 101/I.S. 2-97,
Voluntary Specifications for Aluminum, Vinyl
(PVC) and Wood Windows and Glass Doors.
Testing to this standard for certification in
the AAMA program will end in four years, as of
March 1, 2012. However, test reports will be
permitted for use for their entire four-year
span, so certification and labeling to the 1997
standard will end four years later, as of March
1, 2016.
