Abstract

Overview

ISO 12625-11:2019 - "Tissue paper and tissue products - Part 11: Determination of wet ball burst strength" specifies a laboratory test method to measure resistance to mechanical penetration of tissue paper and tissue products after wetting. Commonly called the wet ball burst strength or wet burst test, this method determines the maximum perpendicular force (wet bursting force) a wetted test piece can withstand before penetration by a hardened ball.

Key topics and technical requirements

Scope and principle
- Applies to tissue papers and tissue products (application to other paper types is possible but not covered).
- A clamped test piece is wetted and loaded perpendicularly by a polished steel ball until penetration.
Reagents
- Use deionized water (conductivity ≤ 0.25 mS/m at 25 °C) maintained at conditioning/test temperature.
Apparatus
- Rigid, vibration‑free setup with concentric annular clamping rings (rubber-coated, inner diameter (50.0 ± 0.2) mm; clause 12 allows 50 mm or 89 mm clamping ring diameters).
- Penetration ball: highly polished stainless steel, diameter (16 ± 0.2) mm, sphericity
