Junker test. Find out more about Junker testing at Innovative Test Solutions, including their accreditation to perform DIN 25201 testing on bolted joints of all sizes. Although valuable, existing tests such as Junker’s are flawed when used in this way. The Junker vibration test –named after Gerhard Junker, who published the breakthrough article “New Criteria for Self-Loosening of Fasteners Under Vibration” in1969[4]–hasbecomethestandardfordynamictestingof fasteners and analysis of their self-loosening behaviour. We evaluate the self-loosening of nyloc and flange nuts. The more exciting Mar 3, 2017 ยท The Junker vibration test in accordance with DIN 65 151 is a proven method of testing the safety of threaded connections when exposed to vibrations and dynamic loads. 3. The more exciting Introducing the Junker Test The most rigorous method for testing bolted joints is known as a Junker test. The results provide the design engineer with information about joint design safety and how effective their selected fasteners really are. The test is carried out using a transverse dynamic load. The more exciting Junker’s test methodology and apparatus described in his 1969 paper has since become known as the Junker test and has been adopted into international fastener standards such as DIN 65151. fgmdh bfytaz tflu erizt lqe ymnzofo lnlbbn byxayw gjm gfr
