SECTION 2
TEST METHODS - NOTES TO TESTING LABORATORY
I. SEALANT SAMPLING
The sealant to be tested should be taken directly from a
randomly selected container as commercially supplied by
the manufacturer. The container should be full and not
previously opened. The testing should be completed
within the shelf life recommended by the manufacturer.
The sealant manufacturer's instructions giving any options
allowed in the test methods should be obtained along with
the sealant sample.
II. HOW TO EVALUATE RESULTS
After testing, examine each group of specimens
representing a given test. Should any one specimen be
found not to meet requirements, the given test shall be
repeated.
NOTE: Only one repeat per test.
If the sealant fails the specific retest, a new sample shall
be submitted and the entire specification shall be tested.
III. OPTIONAL CURE, PRE-CURE OR PRECONDITIONING OF TEST SPECIMENS
PRIOR TO EXPOSURE CONDITIONS
The curing conditions for a test specimen prior to test
requirement exposure; i.e., 180 ± 5oF (82 ± 3oC) for 14
days, may require moisture and/or oxygen to facilitate a
cure. Also, some compounds may require a step-type
temperature gradation for elimination of solvents prior to
test exposure. The following conditions are examples of
such options.
A. 77 ± 5oF (25 ± 3oC) with 50% ± 5% Relative
Humidity.
B. 77 ± 5oF (25 ± 3oC) with 95% ± 5% Relative
Humidity.
C. 100 ± 5oF (38 ± 3oC) with 95% ± 5% Relative
Humidity.
prior to the elevated temperature exposure requirements
in the test.
NOTE: A maximum of 14 days and/or 158oF can be used
as an optional pre-cure.
IV. PEEL ADHESION PREPARATION
ASTM C 794 specifies a peel strip material of desized,
Grade A, Airplane Cloth, 4.28 ounces per yard, 80/84
count. One source for this material is:
R.J. Patton Company
1908 Dunlap Street
Cincinnati, OH 45214
The sealant manufacturer can specify other types of strip
material to insure adequate adhesion between the strip and
the sealant. Other fabrics, foils, or screens may be used.
The peel strip material must be described and noted on the
test report.
NOTE: The above company is listed for convenience
only and is not, in any way, an approval or endorsement
by AAMA.
V. SUBSTRATE PREPARATION
Unless cleaning instructions are given in the individual
test method, clean all metal and glass test surfaces using
the procedure outlined below.
A. Always pour solvent on the rag being used. Never dip
the rag in the cleaning solvent, as this contaminates the
solvent.
B. Use the "Two Rag Wipe" technique. One rag, is used
to wipe off the wet solvent and contaminates from the
surface. Allowing the solvent to dry on the surface
without wiping with a second dry absorbent cloth
merely redeposits the contaminants as the solvent dries.
D. 77 ± 5oF (25 ± 3oC) (Room Temperature Average)
45% to 65% Relative Humidity.
C. Change to clean rags frequently as you see them
becoming soiled. It is easy to see the soiling if white
rags are used.
E. 77 ± 5o (25 ± 3oC) (45% to 65% Relative Humidity) 7
days + 7 days @ 140 ± 5oF (60 ± 3oC).
D. Always use clean containers for solvent use and
storage.
F. 77 ± 5oF (25 ± 3oC) (45% to 65% Relative Humidity) 7
days + 7 days @ 100 + 5oF (38 + 3oC).
E. Follow solvent supplier's recommendations for solvent
use and storage.
Should any of the above variations thereof be specified by
the compound manufacturer, a notation on the test report
will be made indicating the conditions used. If no
conditions are specified by the compound manufacturer,
the standard 7 days at 77 ± 5oF (25 ± 3oC) will be used
NOTE: Sealant manufacturer and/or sealant user should
test specific sealants, substrates, primers (if required) and
cleaning procedures to ensure adequate adhesion is
developed under actual conditions.
AAMA 800-92
Page 6
VI. GUNNABLE SEALANTS
Gunnable sealants with spacer beads and mastic type
tapes with spacer shims cannot be tested to some
requirements within their respective specifications
because spacers will not allow specified test specimen
configuration or can produce results not characteristic of
the same materials without spacers. Therefore, testing
should be done using sealants without spacers or shims.
Testing and acceptance of sealants with spacers should be
agreed to between the sealant supplier and user.
VII. COMPATIBILITY
This specification qualifies a sealant for use. It does not
address the adhesion capability of the sealant for a
specific substrate nor the compatibility of the sealant with
the materials it contacts. Adhesion and compatibility
characteristics required for specific substrates or finishes
may be determined by the following test methods:
NOTE: Several alternative test methods are available
from ASTM.
A. TEST METHOD A - Compatibility with Plastic
Glazing Beads or Setting Blocks
1. Materials Required
a. Two 600 ml high form beaker (no pouring lip). Two

Prepare three specimens as follows:
Place two 1/2 inch (12.5 mm) wide strips of masking tape
on the face side of the aluminum test panel surface.
Position the strips parallel to each other using the panels
long edges as guides. These strips run the entire length of
the panel. (The tape in position on each edge of the face
side is approximately .007 inch (.18 mm) thick.) Place an
additional strip of 1/2 inch (12.5 mm) tape on top of each
applied tape. Position this tape so that it covers the entire
length of the panel. (This double thickness of tape will
serve as a .014 inch (.36 mm) spacer.) Apply a 1/8 inch
(3.2 mm) diameter bead of test compound approximately
1/2 inch (12.5 mm) inside and parallel to each side of the
panel. Apply across bottom of the panel to complete the
"U" shape trough.

(constant rate of extension) or dead weight pendulum
type. The machine shall have one stationary head, one
moveable head, a graduated tension weighing device with
an accuracy of 0.1 pound (45 grams) or less, and be
capable of a head separation rate of 12 inches per minute.
The chamber must be capable of maintaining
temperatures from 32oF to 122oF (0 to 50oC) within ±5oF
(± 3oC).

2.19.1.2 Deep freeze unit capable of maintaining a
temperature of 32 ± 5oF (0 ± 3oC).
2.19.1.3 Air circulating oven capable of maintaining a
temperature of 120 ± 5oF (49 ± 3oC).
A thermometer shall be used to obtain
2.19.1.4
temperature measurements.
2.19.1.5 Six clean aluminum panels 1/16 inch (1.6 mm)
thick x 2 inches (51 mm) wide x 6 inches (152 mm) long.
2.19.1.6 Six clean glass panels 1/8 inch (3 mm) thick x 2
inches (51 mm) x 6 inches (152 mm).
2.19.1.7 A PSTC roller weighing approximately 4.5 lbs.
(2 Kg).
2.19.1.8 A tray which can be clamped by the stationary
head and will restrain a test panel to remain perpendicular
to the movable head, yet allow test panel to slide within
the tray.
2.19.1.9 Reinforced pressure sensitive tape, (Fiberglass
or polyester film) 1/8 inch (3 mm) to 1/4 inch (6 mm)
wider than the tape being tested.
2.19.1.10 Samples of the tape to be tested. Width of tape
shall be between 1/2 inch (13 mm) to 1/4 inch (6 mm)
wider than the tape being tested.
2.19.2 PROCEDURE
2.19.2.1 Scrub the application surface of all metal and
glass panels with a cleaning solvent. Repeat procedure
with a rinsing solvent. Dry wipe each panel insuring no
solvent or lint remains. Do not contaminate panel surface
by stacking or by touching with fingers.
2.19.2.2 Discard the first two layers of the tape from the
roll. Place the tape specimen on each panel, centered
running parallel with the longer side. Specimen shall be
flush on one and have an overhang of 3 inches (76 mm) to
5 inches (127 mm) on the other end of the panel. Avoid
trapping any air pockets under the specimen. If the
adhesive surfaces on a double coated tape differ from one
side to the other, then both should be tested and reported.
In these situations, when testing the second adhesive
surface, adhere the face side of the total length of the
specimen, with liner, to a strip of the reinforcement tape.
Remove the liner and apply the specimen to the test
panels as described above.
purposes. Pass the PSTC roller, without application of
additional pressure over the backing of the tape
lengthwise, one in each direction at the approximate rate
of 12 inches (205 mm) per minute. Once rolling is
complete, remove any additional strips from the panel
while not disturbing the test specimen. Carefully remove
the liner from all test specimens.
2.19.2.4 Apply the reinforcement tape to each specimen
on the side from which the release liner was removed.
Apply the reinforcement tape starting on the end of the
panel that has the specimen flush and continue across the
panel. Insure that the test specimen is completely covered
by the reinforcement tape. Fold the reinforcement tape
over the test specimen overhang approximately 2 inches
(51 mm) so the edges of the reinforcement tape adheres to
itself. This is to insure that values obtained are strictly
adhesion oriented and not a combination of tensile and
adhesion. Insure that the reinforcement tape does not
adhere to touch the panel at any time.
2.19.2.5 Condition the specimens in accordance to the
following schedule:
A. 3 Glass and 3 aluminum panels at 32 ± 5oF (0 ± 3oC)
for 24 hours.
B. 3 Glass and 3 aluminum panels at 120 ± 5oF (49 ±
3oC) for 24 hours.
2.19.2.6 Remove each panel from its conditioning
environment (one at a time and place the panel in the
environmental chamber for a minimum of 15 minutes of
until the specified temperature is stabilized in the
chamber. Insert the overhang of the specimen into the
jaws of the movable head. Insure that the tray is exactly
perpendicular to the pulling direction and that the
movable head is located directly over the test specimen.
2.19.2.7 Test the specimen by peeling at a rate of 12
inches (304 mm) per minute. After the first inch of the
specimen is removed from the panel, record the peel
adhesion values over approximately the next 4 inches
(102 mm) at approximately 1/2 inch (12.7 mm) intervals.
Do not take any readings during the removal of the last
inch of the specimen from the panel. Try to keep the
angle of separation as close to 90o as possible.
2.19.2.8 Calculate the average peel value from all reading
for each sample. Convert average value to pounds/inch
width. Report the converted average value for each of the
12 specimens.
2.19.2.3 In the case of tape widths of less than one inch
(25 mm), cut additional strips from the same roll and
apply parallel and adjacent to the test specimens to
provide a total width of one inch (25 mm) for rolling
