TAPPI

In 1915, thirty enterprising papermakers gathered, determined to form a new technical arm of the American Paper & Pulp Association (APPA). Their idea was to gather and disseminate information on matters related to production. In less than a year, the Technical Association of Pulp and Paper Industry (TAPPI) was formed, and more than 100 years later, its recipe for success continues to work.

TAPPI T274

Laboratory Screening of Pulp (MasterScreen-Type Instrument)

TAPPI T275

Screening of pulp (Somerville-type equipment)

TAPPI T411

TAPPI T414

Internal tear strength of paper (Elmendorf-type method)

TAPPI T441

Cobb Test describes a procedure for determining the quantity of water absorbed by nonbibulous paper, paperboard, and corrugated fiberboard in a specified time under standardized conditions.

TAPPI T448

gravimetric determination of the water vapor transmission rate (WVTR) of sheet materials at 23°C with an atmosphere of 50% RH on one side and a desiccant on the other.
