Compression Testing Machine plastic pipe ring stiffness testing
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.
At the same time, you are welcome to consult and understand.
