GB/T 2679.7-2005 - Board — Determination of Puncture Resistance

GB/T 2679.7-2005 specifies a method for determining the puncture resistance of various types of board materials, including corrugated fiberboard. This test assesses the energy required to puncture the board, ensuring the material's strength and durability for packaging applications.

Scope:

Applicable Materials:

• Various types of cardboard, including corrugated fiberboard, used in packaging applications.

Testing Methodology:

• Uses a pointer-type puncture strength meter to apply force to the specimen until puncture occurs.

• Measures the energy absorbed during puncture to evaluate resistance.

Specimen Preparation:

• Samples are prepared to specified dimensions and conditioned under standardized atmospheric conditions.

Assessment Parameters:

• Higher energy values indicate greater puncture resistance, reflecting the durability and robustness of the material.

Applications:

Quality Control:

• Ensures cardboard materials meet durability standards for safe packaging.

Material Comparison:

• Provides a consistent basis for comparing the puncture resistance of different board materials.

Product Development:

• Aids manufacturers in creating packaging solutions with enhanced strength and protective properties.

Standardization:

• Offers a uniform method for evaluating puncture resistance across various materials.
