Compression Testing Machine ISO 13968 plastic pipe ring flexibility testing 50kN ETM504R


The ETM type R Series with larger test space is specifically designed for plastic pipe ring stiffness testing. Equipped with suitable test grips and fixtures, it can address the needs of standardized and routine testing, providing the user high quality at the most affordable price. The dual column testing systems are suited for tension and/or compression applications with load range requirements from 30kN to 100kN. They are typically used for quality control and production testing.

Standard: ISO 13968

This International Standard specifies a method for testing the ring flexibility of a thermoplastics pipe having a circular cross-section. The method enables determination of the deflection, and necessary force, at which physical damage, if any, occurs within the specified diametric deflection.

Test report
The test report shall include at least the following information:
a) a reference to this International Standard and to the referring standard;
b) the identification of the thermoplastics pipe, including:
1) manufacturer,
2) type of pipe,
3) dimensions,
4) production date,
5) lengths of test pieces,
6) mass per metre length of the pipe;
c) the test temperature;
d) the force/deflection graph for each test piece;
e) where appropriate, the force and deflection at which any of the events specified in 8.2 occurred;
f) the deflection and force at the maximum point, if a maximum occurred;
g) any factors which may have affected the results, such as any incidents or any operating details not
specified in this International Standard;
h) the date of test.

Typical specimens: Plastic pipe, small components, reinforced plastics, metals, wire, composites, elastomers, wood products, textiles, biomaterials, paper products, adhesives, foam, consumer products


  • Pre-loaded ball screws and heavy duty bearings assure long life with zero backlash as well as linear low force and through zero performance. The result is accurate and repeatable measurements that truly represent the specimen characteristics rather than load frame deficiencies

  • Robust guidance columns increase lateral stiffness and ensure linear crosshead travel. This results in accurate crosshead alignment thus reducing variability in measurement data and producing better overall accuracy.

  • High-speed, low vibration, world-class, maintenance-free, Japanese made AC servo motor and servo controller

  • Photoelectrical encoder built in servo motor system is for position measurement of crosshead

  • Non-clutched drives, rated for full speed at maximum force

  • Built-in bidirectional load cell is assembled in the middle crosshead to prevent any collisions and simple to perform compression or tension tests

  • Dual action over-travel limits on all frames provide the highest level of safety and meet all international standards
