This standard specifies a method specifically for determining the zero-span tensile strength of pulp and paper. Its core principle involves using a zero-span tensile strength tester equipped with special clamps to stretch and break a sample strip with a width of 15 mm under conditions where the clamp spacing is extremely small (typically 0 to 0.6 mm). Due to the near-zero clamp spacing, the fibers in the clamped portion of the sample are subjected to force almost simultaneously, meaning the measured force directly reflects the inherent strength of the fibers themselves, rather than the fiber bonding strength of the paper. This method is suitable for evaluating the strength characteristics of fibers in various types of pulp and paper.
