Ultrasonic TSI & TSO Measurement 

"Self-guided, blended learning testing labs examining property measurements and variables." 

Lab Description:

In the 1970’s a relationship was established between the velocity of sound in paper and the elastic modulus (E). This non-destructive technology allows for lab and eventually for on-line measurement and optimization of strength properties.

Scope and Learning Objectives:

These self guided testing labs and video modules demonstrate the procedures used to test paper and board. They will also provide some background about the property being tested. The overall learning objective is to increase your understanding of why and how these tests and procedures are performed.

The outline you should follow for each lab is to learn the background information on the property being tested, note the TAPPI standards that are referenced,then view the video on the correct testing procedure. Sample data is provided. Some of the labs will require calculations and analysis of data, and other labs will provide final data without calculations. A short set of thought questions is included at the end.
