TAPPI TIP 0502-11 2003

TAPPI TIP 0502-11 provides a practical method for estimating the air-dry weight of newsprint rolls using their measured width and diameter. The document explains the underlying cylindrical-volume calculation, defines air-dry weight at 8% moisture content, and includes guidance for adjusting the estimate based on actual roll density. It is a concise reference for newsprint mills, paper manufacturing personnel, production engineers, and technical staff performing roll-weight calculations.

Application Scope: Estimating newsprint roll weight for production, handling, inventory, shipping, and mill operations based on roll dimensions and density.
