The outdoor apparel and gear industry is a very frequent user of universal testing machines (UTM’s). Universal testing machines can be programmed to perform a variety of tension (pull apart), compression (crush), and flexure (bend) tests. Strength and stretch are important design criteria for outdoor and athletic products. It may not be extremely important that a soda bottle withstand a large compressive load but it certainly is important if a rock climbing harness doesn’t break.
This is a test of a side release buckle used to connect a lashing strap. As you can see in the video, this buckle would be fine for lashing a sleeping pad on a backpack, but you certainly would not want to use it for climbing.
