Spring Rate: Accuracy depends on measuring the exact deflection between the coils.
The Master metals standard; bridges the gap between E8 and product specs.
Focuses on checking for peeling/flaking rather than a precise MPa value.
Extreme Stiffness: Ceramics have virtually zero elongation. Any frame squish will ruin your modulus data.
Tests H-specimens consisting of sealant between two glass/metal substrates.
High moisture sensitivity; samples must be conditioned at 50% humidity.
The shear force is applied through heavy steel plates bonded to the core.
Measures the pull-off strength of the skin from the core.
Uses short specimens to force a skin-crushing or buckling failure.
Essential for determining the stabilized vs unstabilized compressive modulus.
Primarily used to determine core shear strength and skin-to-core bond integrity.
Focuses on dielectric breakdown + adhesion.
Bond Line Control: The thickness of the glue determines the stress distribution.
Initiation Force: This test is the starting gun. It measures the peak force to break the surface of a plastic…
Moisture Balance: Wood properties change drastically with humidity; condition for 48 hours minimum.
Initial Contact: Defining the zero point is hard on soft foams. Use a 1N pre-load to establish a consistent start.
Uses bonded-end caps to ensure failure in foam.
Scale Matters: When specimens are this small, the mass of the grip should be as close to zero as possible.
Measures sandwich panel bond strength using a rotating drum fixture.
Peel Rate: The speed of the peel dramatically affects the average force recorded.
