Method and device for loading specimens into tensile testing machine

摘要

A sample loading device may include a top plate and a base plate, and the sample loading device can be roughly divided into two portions: a loading portion and a holding portion. The present invention is advantageous because the test sample is introduced by the sample loading device, which has been designed for a standard T-peel test, so the integrity of the sample introducing process will not be affected even though a different operator is conducting the process. Furthermore, it is easy to for the operator to load the test sample to the sample loading device, as well as transferring the sample loading device to the tensile testing machine, so the errors during the sample loading process can be significantly reduced. In other words, the T-peel test results can be more reliable when the test sample is introduced by the sample loading device in the present invention.

主权项

1. A sample loading device for measuring the seal strength in flexible barrier materials comprising a loading portion and a holding portion, said the loading portion having a top plate and a base plate, said loading portion having a receiving groove on the top plate, and a gap formed on the loading portion between the top plate and the base plate, wherein the loading portion is configured to receive and hold a test sample with a predetermined configuration, and holding portion is configured to be held by hand to transfer the loaded test specimen to a tensile testing machine,
wherein the test sample is a T-type specimen having a sealed portion and two wing portions extending from one end of the sealed portion, wherein the receiving groove is formed at a predetermined distance from a center portion of the top plate of the loading portion to receive the sealed portion of the T-type specimen, while the wing portions are slid into the gap on the loading portion between the top plate and base plate, wherein the sealed portion of test sample is slid into the receiving groove from an entering point, and being stopped at a stopping point, and a distance from the entering point to the stopping point, namely the length of the receiving groove, is substantially equal to or slightly greater than the length of an edge of the sealed portion of the T-type specimen.
