Standard Specification for
Laminated Architectural Flat Glass1
This standard is issued under the fixed designation C 1172; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
1. Scope
1.1 This specification covers the quality requirements for
cut sizes of flat laminated glass consisting of two or more lites
of glass bonded with an interlayer material for use in building
glazing.
1.2 Depending on the number, thickness and treatment of
plies, and the number and thickness of interlayers, the glass
shall be laminated for applications including but not limited to
safety security, detention, hurricane/cyclic-wind resistance,
blast resistant, bullet resistant and sound reduction glazing
applications.
1.3 Optical distortion and the evaluation thereof is not
currently within the scope of the standard. Mockups are
recommended as a method to evaluate glass. (See Appendix
X1.)
1.4 The dimensional values, except thickness designations,
stated in inch-pound units are to be regarded as the standard.
The values given in parenthesis are for information only.
1.5 The following safety hazards caveat pertains only to the
test method portion, Section 7, of this specification. This
standard does not purport to address all of the safety concerns,
if any, associated with its use. It is the responsibility of the user
of this standard to establish appropriate safety and health
practices and determine the applicability of regulatory limita-
tions prior to use.

7.11 Transmittance—Using Practice E 308, measure trans-
mittance by illuminating each laminated specimen at normal

8.2 Edge—An edge shall be cut, sawed, ground, sanded to
remove sharp edges only, seamed, ground and polished,
beveled, or mitered as specified.
8.3 Marking:
8.3.1 Each laminate, as supplied by the manufacturer, shall
bear the manufacturer’s name, or trademark, or both, unless
otherwise specified.
8.3.2 Laminated glass intended for safety glazing applica-
tions specified by building codes, shall be permanently marked
as required by the applicable safety glazing standard.
8.4 Thickness—For thickness tolerances consult the lamina-
tor. Nominal thickness tolerance computation guidelines are as
follows:
8.4.1 Minimum Thickness Tolerance—Minimum thickness
tolerance shall be the summation of the values for the mini-
mum thickness of each glass ply obtained from Specification
C 1036 and the minimum interlayer thickness obtained from
the laminator.
8.4.2 Maximum Thickness Tolerance:
8.4.2.1 Annealed Glasses—The summation of the values for
the maximum thickness of each glass ply obtained from
Specification C 1036 and the maximum interlayer thickness
obtained from the laminator.
8.4.2.2 Heat Treated Glasses—Add 0.031 in. (0.79 mm) to
the overall maximum thickness of the laminate.
8.5 Length and Width:
8.5.1 Length and width tolerances of symmetrically lami-
nated glass shall be in accordance with Table 2 when measured
in accordance with 7.9.
8.5.2 For length and width of nonsymmetrical laminated
glass contact the supplier for size tolerances.
8.6 Flatness:
8.6.1 For annealed transparent glasses the overall bow and
warp shall not exceed 1⁄16 in. (1.6 mm) per foot (300 mm) of
length when measured in accordance with 7.8.
8.6.2 Because of the nature of the processes used in manu-
facturing heat-strengthened, rolled, tempered, or wired glass,
these glasses may not be as flat as annealed transparent glass.
The deviation from flatness of laminated glass depends on
glass type, thickness, width, length, laminating process, and
other factors. For other than annealed transparent glasses the
overall bow and warp shall not exceed the values shown in
Table 3 when measured in accordance with 7.8.
8.6.3 Localized warp for rectangular laminated glass shall
not exceed 1⁄16 in. (1.6 mm) in any 12 in. (300 mm) span of
edge.
8.7 Blemishes—Maximum allowable laminating process
blemishes shall not be greater than those listed in Table 1.
