CSI-172 (Flexural Creep Tester )
The CSI-172 Flexural Creep Tester is used to measure the tensile and compressive creep and creep-rupture resistance of plastics under specified environmental conditions.

The Flexural Creep Apparatus consists of:

rigid test rack
stirrups
dial indicators
loading system

The test specimen is normally a rectangular bar conforming to the requirements of Section 5 of test Method D790. The test rack provides support of the specimen at both ends with a span equal to 16 (+4, -2) times the thickness. The stirrup has a 3.2mm (.125 inch) radius. The deflection of the specimen is measured at mid-span using a dial indicator.
Units are available for testing simultaneously 5, 10, or 15 specimens.
Optionally, high temperature dial indicators may be supplied for special requirements, as well as resolution indication.
