Below are the general procedures and equipment for each test. testing standard required for testing adhesives

ASTM D903

Equipment:

• Micrometers and/or callipers

• Deflectometer/Deflection gages (ONLY if the UTM can’t measure the displacement)

• Conditioning Chamber

• Environmental Testing Chamber

• 3-point bend fixture

• UTM

Procedures:

• Prep the specimen.

• Precondition the test specimen.

• Test the specimen as soon as possible after conditioning

• Place the specimen in the test apparatus

• Wait until failure

ASTM D950

Equipment:

• 3 Force Indicator

• Grips

• Strain Indicating Device

• Extensometer

• Strain Gauge

• Tabs( We should probably fabricate our own tabs)

• UTM

Procedures:

• Put the specimen in the jig that is in the vise of the machine so the specimen butts squarely against the end of the jig.

• Rest the impact head against the specimen and adjust the jig so the head fits squarely against the impact face.

• Raise the impact head and release the safety catch.

• We will then note the impact energy absorbed.

ASTM D5868

Equipment:

• Compression fixture

• Strain-indicating device

• Special alignment jig

• Bonded Resistance Strain Gauges

• Emery cloth

• I believe UTM

• Conditioning chamber

• Environmental test chamber

• Extensometer

Procedures:

• Apply the adhesive in accordance with the adhesive suppliers recommendations. 

• Adhesive Cure—Cure the adhesive at room temperature or elevated temperature using prescribed conditions determined by the adhesive supplier.

• Condition the test specimens

• Place specimens in UTM

• Wait for failure
