Pull testing is a term used to determine the strength of wiring systems. This method makes sure that the wire harness meets its required engineering standards and is of the highest quality that promotes a longer lifespan. This also makes sure that the wire supplied conforms to customer’s specifications. The testing methods include the following:
Consolidatedriggingandlifting.com and other foot rigging shops noted that this is ideal for collecting data, especially the breaking strength of the sample wire. Having the right knowledge about the tensile strength of the harness wire is important because it can help resolve concerns related to the mechanical properties of wiring systems. It can tell the electrical reliability of your folded connection accurately, as well.
Many manufacturing processes use crimp height to test quality control. The reason manufacturers measure the height of the welded or crimped terminal is to check if the wire has been crimped with the least pressure and to the maximum possible die cavity. This is an easy test to pull and is non-destructive by nature.
Another indication for the operator is the crimp pressure. This helps you find out if the wire can offer the required quality of harness of wiring systems. There are pressure monitors available, which you can use to determine its pressure. Many smaller harness manufacturers, however, find it difficult to do because there are no hand tools available and the monitor for testing the pressure can be costly.
The frequency of the pull testing depends on many different factors and varies from manufacturer to manufacturer. The best possible plan is to test the sample wire more often and then reduce the frequency as you go by.
