ASTM D6272 Four-Point Flexure Test Fixture

The ASTM D6272 Four-Point Flexure Test Fixture is engineered in accordance with ASTM D6272 for evaluating the flexural properties of unreinforced and reinforced plastics, as well as electrical insulating materials. Built with robust steel and equipped with a built-in positioning device for quick and accurate specimen centering, it ensures precise measurement of flexural strength and modulus. Compatible with deflectometers for advanced strain measurement, it provides reliable data for material R&D, quality assurance, and structural analysis.

Overview

The Four-Point Flexure Test Fixture is engineered in accordance with ASTM D6272 for evaluating the flexural properties of unreinforced and reinforced plastics, as well as electrical insulating materials. This fixture provides precise measurement of flexural strength, flexural modulus, and material deformation under four-point bending loads.

Design Features and Benefits

Precise Specimen Centering:
Equipped with a built-in positioning device to ensure quick and accurate specimen centering, significantly improving measurement precision and operational efficiency.
Robust Construction:
Built with high-strength steel to provide exceptional stiffness and durability during testing.
Deflectometer Compatible:
Supports optional deflectometer attachment for accurate strain measurement during flexural testing.

Applications

Primary Purpose:
This four-point flexure fixture is specifically designed to determine the flexural properties of unreinforced and reinforced plastics and electrical insulating materials. The acquired material data includes flexural strength, flexural modulus, and deformation behavior during the bending process. For more accurate strain measurement, it can be used in conjunction with a deflectometer. It provides robust data support for material research and development, quality assurance, and structural design and analysis.
