Paper Properties and Testing Labs 

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

INTRODUCTION & OVERVIEW

These labs and videos demonstrate 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 understanding of what the tests are telling us.
Scope and Learning Objectives:

These labs and videos demonstrate various 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.

Laboratories are available as Site Licenses which allow unlimited training at a site (ideal for colleges and /universities).

Some of the labs offer sample calculations and analysis of data, and other labs will provide final data without calculations. Each lab contains the following:

1. Learning Objectives.
2. Background on the property being measured
3. Reference to a TAPPI Standard
4. Video showing the proper procedure for the test
5. Sample test data and calculations
6. Thought Questions.
