The International Organization for Standardization (ISO) is an independent, non-governmental, international organization that develops standards to ensure the quality, safety, and efficiency of products, services, and systems.
The purpose of ISO 15490 is to improve products and services while enhancing the efficiency of companies, governments, and other organizations. Some ISO standards are tailored for specific industries, such as the food industry, while others focus on improving environmental sustainability.
ISO 15490 Test Standard
ISO 15490 is an international test standard designed for determining the tensile strength of monolithic advanced ceramics under uniaxial loading at room temperature.
Ceramics possess a high elastic modulus and maintain consistent performance at elevated temperatures. This makes them highly resistant to wear and corrosion.
Today, ISO standards are widely used by both corporate and government bodies. In Malaysia, many industries adopt the ISO 15490 standard in their operations.
Generally, the ISO 15490 test standard measures the strength and deformation of materials under uniaxial tensile stress. This information is valuable for material comparisons, quality control, structural design, and acceptance testing for commercial shipments.

Extensometers for ISO 15490
This test does not require an extensometer, as its primary purpose is to determine the tensile strength of the material rather than measure elongation displacement.
Type of UTM Machine for ISO 15490
For ISO 15490 testing, we recommend using UTM machines with a capacity of 5kN-100kN, depending on the material strength. A dual-column floor-type machine is also recommended.

Test Procedure for ISO 15490
- Prepare the specimens as described in the method.
- Place the specimen into the grips.
- Clamp the specimen at the top grip first, then carefully clamp it into the bottom grip.
- Zero all testing machine settings before starting the test.
- Begin the test by clicking the start button on the software.
- End the test after the specimen breaks (rupture).
