SGS-IPS Testing performs pulp and paper testing following the TAPPI test methods at its laboratory headquartered in Appleton, Wisconsin.

These TAPPI standards are testing procedures and related practices used in the measurement, evaluation, and description of pulp, paper, and related products, including raw materials used in their manufacture, use, or in scientific investigations of any such substances. TAPPI Useful Methods (UMs) describe tests, procedures, or practices written in the same general style as a TAPPI Standard Test Method, but with minimum precision requirement. UMs do not receive the same review through a consensus process, and thus are not Standards.
