ASTM C365 Standard Test Method for Flatwise Compressive Properties of Sandwich Cores

Scope:
This test is for the determination of the compressive strength and modulus of sandwich core materials.

Procedure:
After conditioning and machining the specimen to appropriate specifications, the specimen is centered on the lower platen.  Proper centering is crucial to achieve uniform loading.  Preloading is required before proceeding with the test to ensure immediate load ramp during strain.

Data:
Compressive strength, strain, and modulus of elasticity

Equipment Used:
Loading platens, Test frame

Test Setup

platens
