Labs will use the TAPPI Method T809 to determine crush resistance. Samples ship second week of each month prior to the month during which testing is conducted.

Labs will use the TAPPI Method T824 to determine fluted edge crush. Samples ship second week of each month prior to the month during which testing is conducted.

Labs will use the TAPPI Method T822 to determine ring crush strength. Samples ship second week of each month prior to the month during which testing is conducted.

Labs will use the TAPPI Method T826 to determine short span compression (STFI). Samples ship second week of each month prior to the month during which testing is conducted.

This program provides labs with larger samples intended for use on Autoline systems. Labs will use TAPPI Methods T807, T826, T575, T538 and T460. Participants can report data to be included in Tests 205, 223, 228, 229, and 237. Participation is limited to the United States (including D.C. but excluding other territories).
