This test method is chiefly intended for testing tissue papers that are in direct contact with silver. The test results indicate the type of tarnish or stain and the relative distribution of the materials causing such tarnishing or staining.
Note 1-The main material in paper causing silver to tarnish or stain is reducible sulfur, which may be determined in accordance with Test Method D 984.
