ISO 23242:2020 PDF

Overview

ISO 23242:2020 specifies a laboratory test method for flexural strength of monolithic ceramic thin plates at room temperature using three‑point or four‑point bending. It applies to fine ceramics (advanced/technical ceramics) and to whisker‑ or particulate‑reinforced ceramics that are macroscopically homogeneous. The standard covers thin plate specimens with thicknesses from 0.2 mm to 1.0 mm and is intended for material development, comparison, quality assurance, characterization and reliability data generation. Continuous‑fibre‑reinforced ceramic composites are excluded.

Key topics and technical requirements

• Specimen scope and preparation
  • Applies to monolithic and whisker/particulate‑reinforced ceramics; thickness range 0.2–1.0 mm.
  • Describes machined and as‑fired specimen preparation, marking, handling and number of test pieces.
• Test configurations
  • Three‑point and four‑point flexure geometries with specified spans and moment arms (see table in standard).
  • Bearing diameters specified (typical 4.5–5.0 mm; for d
