Tensile Testing for Wiring Harness Connections
The only way of really knowing the strength of a crimped terminal is to pull it. This can reveal production problems, where strand nicks, incorrect crimp height, or effects from changes in terminal supply, may not be clearly apparent.

Why is texture testing important?
Texture testing ensures consistent product performance, supports process control, and validates compliance with industry standards. Even small changes in raw materials, processing conditions, or environmental factors can alter texture.

Texture Testing for Bakery Applications
The primary goal for using instrumentation to measure texture is to capture an objective value to something that is typically evaluated very subjectively. Texture cannot be controlled unless it measured in a consistent and repeatable manner.
