Instruments as per ASTM D4918-97(2002)
Standard Method of Test for Co-efficient of Static Friction of Uncoated Writing and Printing Paper by Use of the Inclined Plane Method
The standard ASTM D4918-97 (2002) explains a method to determine the coefficient of static friction of paper considered when sliding against it. The inclined plane test method is used. Although the procedure is basic in the said conception, the accurate statement has been created with printing papers and in uncoated writing. Although the use of this test standard is recommended for those grades only, still it is used with other types of paper that give specific attention to paper characteristics with the understanding that accuracy may not be the same.
