Corrugated Fiberboard -

Determination of Bursting Strength

1 Scope

This Standard specifies using the hydraulic increase method to determine the bursting

strength of the corrugated fiberboard.

This Standard is applicable to the corrugated fiberboard with bursting strength of

350~5500kPa.

GB 450-1989 Paper and Board - Sampling for Testing

GB 10739-1989 Paper Board and Pulps - Conditioning of Samples and Testing

Atmospheres

3 Definitions

For the purpose of this Standard, the following definition apply.

4 Test Principle

Place the sample on the adhesive film; clamp it with the sample clamp; and then apply

pressure evenly to make the sample and the adhesive film freely protrude until the

sample ruptures.

5 Test Instrument

6 Sample Taking and Handling

7 Preparation of Sample

The sample area must be larger than the chuck of the burst tester; and the sample

must not have watermarks, creases or obvious damage.

8 Test Procedures

Cut samples and test under the atmospheric conditions specified in 6.2.

Open the sample chuck; clamp the sample in the middle of the two sample chucks;

then start the analyzer; and gradually increase the pressure at a rate of (170±15)

mL/min.

9 Result Expression

The test is carried out on 10 samples each attached to the film on the front and back

sides, and is expressed by the arithmetic mean value (kPa) of all tested values.
