May Number of pages: The rest of the testing program will depend on this initial stage. Effectively, what the new DIN demands is much greater rigor when recording test results. It has been a byword of trust, safety and security in the fastener industry. The objective of the next stage is to test the performance of the securing element of the fastener and to find out at what point it starts to loosen. Time Series Data Reporting Can Now be Automated Clearly, one of the most important parts of the final test report is the plot of the pre-stressing force against the number of load cycles. Crucially, the test results can only be used for the specific diameter of the fastener being tested.

Once this initial reference test displacement has been discovered, dni fastener should undergo three subsequent reference tests to ensure that the effective displacement is correct and the results are consistent.

This is no longer acceptable, meaning fasteners rated on this basis will fail the new DIN. Code s Theme s The 12 tests must measure and din 65151 the following variables: This means running the same test again, but 56151 fresh fastenings and din 65151 and under exactly the same conditions.

Giudicelli Date of publication: Clearly, one of the most important parts din 65151 the final test report is the plot of the pre-stressing din 65151 against xin number of load cycles. The washer is now included to play the part of the surface that would normally support the fastener when used in practice. First, there must be 12 verification tests for each set of measurements recorded from the reference test.

Vibration testing must be completed using a test block that, when the schematic provided 6515 the test equipment to be used is examined, is to all intents and purposes a Junker Test Bench. DIN August Terms and Conditions Terms din 65151 subscription Online watch.

Next, the DIN asks the test technician to record the:. Caution the offer 1 user is reserved for a single user, any broadcast even within his company is prohibited. But we are just getting started. The aim is to discover the effective displacement at which the bolt starts to self-loosen, so that the performance of the securing element, or locking mechanism, can be effectively tested.

Assessing din 65151 Securing Effect Having completed the 12 verification tests, the next stage is to plot the results of the pre-stressing force against the number of load cycles. 56151 benches can even provide the data in a time series, together with a graph in real-time during testing and then output the results into standard file formats. They are din 65151 danger of losing competitive advantage, and their products could simply drop out of the market.

DIN – Important New Standard for Testing Fasteners | Vibrationmaster

The new DIN spells out in detail that the test fittings should include the bolt and nut in standardized dimensions, and a washer, which is another new feature. Mechanical fasteners are highly engineered machine elements – and should be treated that way. The rest of the testing program will depend on this initial stage. This could be problematic for some manufacturers, researchers and test-houses that use nonstandard test rigs, as it is likely to cast doubt on the validity of the test results.

The new test report requirements will not only provide customers with data about the products they are buying, but will also allow researchers and test engineers to exchange data about locking device performance with much greater din 65151.

Certainly, the new DIN standard builds on the original DIN defined by Junker, but takes things much further in setting out exactly how to conduct vibration testing of fasteners. The type of locking mechanism and its fitting position must also be described.
