Grading Rubric Name(s): __________________________________________________________________ Sec _____ 1. Basis Weight and Grammage a. Explain “basis weight” and “grammage” in your own words. b. Show your paper weight calculations c. What is the advantage of using grammage instead of basis weight or M weight to describe paper weight?

/2 marks /6 marks /4 marks

2. Folding Endurance a. Which paper had the highest folding endurance? Lowest?

/2 marks

b. What factors affect folding endurance? c. How is folding endurance related to grain direction? Why?

/3 marks /3 marks

3. Tensile strength/tensile index a. Which paper had the lowest lowest tensile strength? Highest?

/2 marks

b. Which of the tested papers had the lowest standard deviation? Reasons why? Highest? c. What paper manufacturing factors contribute to the tensile index? d. For which applications is tensile strength an important factor?

/2 marks /2 marks /2 marks

4. Brightness a. Which paper had the highest brightness? Lowest? b. What factors contribute to brightness?

/2 marks /4 marks

5. End Use a. For each of the four properties tested, give two specific examples of end use requirements. Avoid using examples given in class. b. Write a short profile about each paper from the testing you did. What do you know about each paper? Describe it. What purposes should it be used for? What should it not be used for? Show that you are able to synthesize and link the knowledge gathered from all four tests.
