About This Item


Full Description

TAPPI T 844 pm-15 describes a procedure to determine the nominal basis weight (grade) of the components of corrugated board. It is based on TIP 0308-01, now withdrawn. Test specimens of corrugated fiberboard are treated with water so that the component layers can be separated, dried, and weighed. The goal of the method is not to determine the exact basis weights of the papers comprising a corrugated specimen, but rather to identify the probable marketing grade under which the papers were likely sold.

This method is applicable to all types of corrugated fiberboard
