ASTM D6272 Standard Test Method for Flexural Properties of Plastics and Electrical Insulating Materials by Four-Point Bending

ASTM D6272 covers the assessment of the flexural properties of electrical insulating materials in the form of rectangular bars that are cut from sheets, plates, or molded shapes, as well as high-modulus composites and unreinforced and reinforced polymers. These testing techniques can be used on both rigid and semirigid materials. However, materials that do not break or fail in the outer fibers cannot have their flexural strength measured. Using a four-point loading system on a simply supported beam, this test method

    Introduction to ASTM D6272

    The test method’s calculated flexural properties are particularly helpful for quality control and specification-related tasks. The location of the highest bending moment and maximum axial fiber stress distinguishes four-point bending modes from three-point bending modes. The maximum axial fiber stress in four-point bending is evenly split between the loading noses. MaTestLab is one of the best testing service providers, with the best network of testing laboratories in the USA to carry out ASTM D6272 tests for our clients. The maximum axial fiber stress in three-point bending occurs directly beneath the loading nose. The differences in straining rates mentioned in Procedures A and B, as well as specimen depth, temperature, and ambient conditions, can all affect flexural characteristics.

    Test Fixtures InstallationThe test fixtures are installed inside the chamber
    Testing at Ambient TemperaturesTesting is done in a temperature-controlled environment. The chamber is equipped with inbuilt heaters to raise the temperature. CO2 is used in the chamber as a coolant at lower temperatures.

    ASTM D6272 Test Specimens

    Specimen DetailASTM D6272 covers the assessment of the flexural properties of electrical insulating materials in the form of rectangular bars that are cut from sheets, plates, or molded shapes, as well as high-modulus composites and unreinforced and reinforced polymers.
    Specimen SizeSample sizes with thicknesses of t<1/16 inches, t>1/16 inches, thermosetting sheets, molded materials, and high-strength toughened composites are all used in ASTM D6272. Typically, five specimens are examined.

    ASTM D6272 Test Results

    ASTM D6272 offers a consistent process for figuring out the flexural characteristics of a variety of plastic materials, such as electrical insulating materials, high-modulus composites, and both reinforced and unreinforced plastics. The technique applies to specimens in the shape of rectangular bars, which can be cut from sheets, plates, or molded shapes, or they can be molded directly. 

    Tests Related to ASTM D6272 ASTM D6272 is related to tests including ASTM D618 for plastics conditioning, ASTM D638 for tensile properties of plastics, and ASTM D883 for plastics-related terms.
