GB/T 4740-2024 specifies the methods for determining the compressive strength and flexural strength of ceramic materials at room temperature. It is applicable to conventional ceramics, bioceramics, nanoceramics, and auxiliary materials, covering various application scenarios such as aerospace and electronic information. The standard defines the dimensions and machining accuracy requirements for cylindrical compressive specimens and rectangular flexural specimens, and optimizes testing procedures such as specimen drying. The tests require the use of a compressive/flexural strength testing machine with a relative error of no more than 1%, along with instruments such as a vernier caliper with an accuracy of 0.02 mm, a controllable oven at 110°C ± 5°C, a balance with an accuracy of 0.1 g, and a desiccator to ensure accurate and reliable test data. This provides a unified technical basis for quality control and application selection of ceramic materials.
