This method describes the procedure for determining dry tensile strength, peak stretch, and tensile energy absorption of paper towel and tissue products using a constant-rate-of-elongation apparatus.

This procedure is applicable to all types of towel and tissue including bath, towel, napkin, and facial. The procedure applies to instruments performing either vertical or horizontal tests. The procedure was written for computer controlled instruments, since these are almost universally used for paper measurement activities. Manual instruments may be suitable for performing this test; however, the user is responsible for making this assessment and complying with the technical requirements described in this method. This procedure does not apply to any other grade of paper, paperboard, combined corrugated board or handsheets.
