In the UK, BS 8597 and CARES Technical Appendix TA1-A specifies fatigue test requirements for mechanical couplers. ISO 15835 also specifies high cycle fatigue tests for couplers. R-TECH Materials can conduct testing to either standard using our range of computer controlled fatigue test equipment. Splice lengths up to 1.3m can be accommodated.
Fatigue testing can be either on one of our electro-magnetic resonance machines up to 400kN or the 270kN servo-hydraulic test machine. The former tests in the frequency range 80-140Hz, whereas the latter tests at defined frequencies in the range up to 30 Hz.
