Environmental Testing

AIR-OVEN AGING

Retouched air oven test

Scope

To evaluate physical and chemical properties of Lapp wire and cable and insure that these products retain critical qualification values of tensile strength and elongation after being exposed to accelerated environmental conditions. These tests are performed to verify compliance with Lapp Oil Resistance Cable Attributes, Industry Tests and Safety Agency Standards.

 

Technical Detail

Multiple un-aged samples that are tubular or have been die-cut to specified length are prepared and then placed within mechanical air-convection oven. If specimens are to be chemically tested, they must be fully submerged. The oven temperature is elevated to the required level for the specified period of time. Upon aging completion, the samples are removed and allowed to relax under an ambient environment for the appropriate time interval. The sample is then subjected to being vertically pulled at a specified rate of speed in which the process is initiated and controlled remotely. The test has been completed once the specimen breaks. Test results are compared to standard requirements electronically to avoid potential error and ensure accuracy.
