Comprehensive guide to filament / 3d printing material testing methods and terminology.

Standard

ASTM D638

ASTM D638 is a standard test method for determining the tensile properties of unreinforced and reinforced plastics.

Mechanical property

Charpy Impact Test

The Charpy Impact Test is designed to measure how much energy a material can absorb when it is hit suddenly.

Physical property

Density

Density measures how much mass a 3D printing filament has per unit volume.
