MIL-PRF-13830B
APPENDIX D
D.4.3.2 Normal conditions (room temperature)..Strength properties shall be
determined for room temperature adhesive at 23° ± 2°C, no sooner than 10 minutes
after specimens have reached equilibrium at such temperature.
D.4.3.3 Elevated temperature Conditions. Conditioning of specimens for elevated
temperature shear strength tests shall require a suitable oven to maintain the
specimen at 71° ± 2°C for a period of 60 minutes prior to testing.
D.4.3.4 Low temperature conditions Conditioning of specimens for low
temperature shear strength tests shall require a suitable conditioning chamber to
maintain the specimens at -51° ± 2°C for a period of 60 minutes prior to testing.
D.4.3.5 Humidity conditions. Conditioning of specimens for humidity shear
strength tests shall require a suitable conditioning chamber to maintain the
specimen at 71° ± 2°C and 95 to 100% relative humidity for a period of 10 days prior
to testing.
D.4.4 Preparation of test specimens.
D.4.4.1 Preparation of shear test specimens. Test specimens as shown in
Figure 1D shall be prepared in sufficient quantities for all the necessary tests.
Specimens for testing all the Table 1 properties shall be prepared from 0.32 cm (min)
by 2.54 cm by 10 cm 2024-T3 aluminum conforming to ANSI/SAE AMS 4035; and
glass microslides 2.54 cm by 2.54 cm by 0.30 cm (min). The cleaning, priming, and
bonding procedures shall be in accordance the manufacturer’s instruction sheet.
The test specimens are to be assembled as shown in Figure 1D with the glass forming
a bond of 6.45 sq. cm to one aluminum adherent and 3.23 sq. cm to the other
aluminum adherent.
D 4.4.2 Preparation of thermal and mechanical shock stability test specimens.
Test specimens shall be prepared in sufficient quantities for all the necessary tests.
Specimens for testing the thermal and mechanical properties shall consist of right
angle optical glass prisms 4 cm x 4 cm x 4 cm bonded to an aluminum plate
6 cm x 6 cm x 1.0 cm. The priming and bonding procedures shall be in accordance
with the manufacturer’s instruction sheet.
D.4.5. Qualification tests.
D.4.5.1 Qualification retest. Unless otherwise specified by the qualifying activity,
adhesives which have previously passed the qualification tests but have subsequently
