GB/T 26460-2011 "Pulp—Determination of zero-span tensile strength (dry or wet)" specifies the methods for determining the zero-span tensile strength of pulp in both dry and wet states, applicable to all types of pulp. Using a zero-span tensile tester, a thin sheet sample of pulp is stretched under conditions where the clamps have zero gap, and the maximum force at break is measured to calculate the tensile strength. The standard defines requirements for sample preparation (sheet forming, drying or wetting treatment), instrument calibration, and testing speed. Dry and wet tests follow their respective operational procedures, reflecting the inherent bonding strength of pulp fibers.
