Описание (английский):

ISO 2759:2014 specifies a method for measuring the bursting strength of board submitted to increasing hydraulic pressure. It is applicable to all types of board (including corrugated and solid fibreboard) having bursting strengths within the range 350 kPa to 5 500 kPa. It is also applicable to papers or boards having bursting strengths as low as 250 kPa if the paper or board is to be used to prepare a material of higher bursting strength, such as corrugated board. In such cases, the measurements will not necessarily have the accuracy or precision stated for this method.

Overview

EN ISO 2759:2014 - "Board: Determination of bursting strength (ISO 2759:2014)" is a CEN-endorsed test standard that specifies a hydraulic method to measure the bursting strength of paper and board. The method uses an elastic diaphragm pressed against a clamped circular test piece while hydraulic pressure is increased until rupture. It applies to all board types (including corrugated and solid fibreboard) with bursting strengths from 350 kPa to 5 500 kPa, and to papers/boards down to 250 kPa when they are components of stronger combined materials.

Key topics and technical requirements

Principle: Maximum hydraulic pressure required to force a rubber diaphragm through a clamped circular area until rupture (bursting pressure).

Applicable range: 350–5 500 kPa (250 kPa minimum for component testing).

Apparatus essentials:

Clamping system with annular, parallel, grooved plates; clamping pressure repeatable and within 700–1 200 kPa.
Elastic diaphragm (natural or synthetic rubber) with specified recess and bulge characteristics (e.g., 10 mm ±0.2 mm bulge: 170–220 kPa; 18 mm ±0.2 mm bulge: 250–350 kPa).
Hydraulic system using compatible liquid (e.g., glycerol, ethylene glycol, silicone oil) with pumping rate 170 ml/min ±15 ml/min; system must be free of air.
Pressure-measuring system with display accuracy of ±10 kPa or ±3% (whichever greater) and response such that peak pressure is within ±3% of true peak (see Annex D).

Calibration & maintenance: Regular calibration of pumping rate, pressure-sensor and clamping indicators; diaphragms checked and replaced when bulge specs fail.

Sampling & conditioning: Test pieces must be representative (ISO 186) and conditioned per ISO 187; grammage used for derived burst index (ISO 536).

Precision & testing guidance: Precision data and clamp dimensions/testing procedures provided in normative annexes (Annexes A–E).

Applications

Quality control and acceptance testing of paper, board and carton materials.

Specification verification for packaging (flat or corrugated) and converted products.

R&D and material comparison (bursting strength and burst index).

Supplier qualification and production troubleshooting where mechanical strength under pressure is critical.
