GB/T 1043-2008 - Plastics—Determination of Charpy impact properties

GB/T 1043-2008 specifies the standardized method for determining the Charpy impact strength of plastics. The test evaluates the ability of a plastic specimen to absorb energy during fracture under specified conditions using a pendulum impact tester. This provides critical data for assessing material toughness and its resistance to sudden forces.

Scope:

• Test Methodology: Details procedures for conducting Charpy impact tests on notched plastic specimens.
• Energy Measurement: Specifies energy absorbed during fracture, expressed per unit cross-sectional area of the specimen.
• Material Suitability: Applicable to various rigid plastics, including thermoplastics and thermosetting materials, with or without reinforcement.
• Environmental Testing: Allows testing under different environmental and temperature conditions to analyze material behavior.

Applications:

• Material Selection: Useful for selecting plastics that meet specific impact resistance requirements.
• Quality Control: Ensures consistency and reliability in the manufacturing of plastic products.
• Performance Analysis: Helps in understanding the impact performance of plastic materials in critical applications.
• Research and Development: Supports the development of new plastics with enhanced impact resistance.
