ASTM D638 test method covers the determination of the tensile properties of unreinforced and reinforced plastics in the form of standard dumbbell-shaped test specimens when tested under defined conditions of pretreatment, temperature, humidity, and testing machine speed.

This test method is applicable for testing materials of any thickness up to 14 mm (0.55 in.). However, for testing specimens in the form of thin sheeting, including film less than 1.0 mm (0.04 in.) in thickness, ASTM standard D882 is the preferred test method. Materials with a thickness greater than 14 mm (0.55 in.) shall be reduced by machining.

Simple and effective method to hold specimens; Dual acting design, also for asymmetrical samples

Jaws articulate and provide a self-aligning and self-tightening effect; 

Opening: 0 – 15 mm (depending on jaws)

Weight: 2.2 kg per pair of grips without jaws

Clamping force: 10 kN at 15 Nm torque

Specification:
