TAPPI is the leading technical association for the pulp, paper, packaging, and converting industries. Its T-series test methods are used worldwide for the strength testing of paper and board.
Why TAPPI standards matter in testing
A TAPPI method standardizes conditioning, specimen size, and procedure so tensile, tear, burst, and compression results for paper and board are comparable between mills and laboratories.
What TAPPI standards cover
TAPPI methods relevant to a universal testing machine include tensile strength, internal tearing resistance, compression (ring crush, edge crush), and bond strength of paper, board, and containerboard.
How to read a TAPPI designation
TAPPI test methods use a T number with a status code and year:
| Part | Example | Meaning |
|---|---|---|
| Prefix | T | Test method (here paper/board series) |
| Number | 494 | Sequential method number (tensile of paper) |
| Status / year | om-13 | Official method, revised in the indicated year |
