Key answer
Mechanical performance is influenced by geometry, matrix composition, moisture, drying, backing, storage and test method.
Avoid a single-number shortcut
No generic hardness value proves that every array will perform in every application.
Define the method
Fixture, speed, orientation, sample conditioning and acceptance criteria should be documented.
Connect results to use
Mechanical data becomes useful when interpreted with array integrity, handling, dissolution observations and application context.
