TAPPI T 580 om-20
Thickness (caliper) of towel, tissue, napkin and facial products
1. Scope 1.1 This method describes the procedure for measuring bulking thickness and variations in tissue paper and tissue products. 1.2 This test method uses a relatively low-pressure 2 kPa (0.3 psi) because of the collapsible structure of tissue paper. TAPPI T 411 “Thickness (caliper) of paper, paperboard, and combined board” uses a relatively high-pressure 50 kPa (7.3 psi). 1.3 An essentially identical method is described in ISO 12625-3 “Tissue paper and tissue products -- Part 3: Determination of thickness, bulking thickness and apparent bulk density.”
