Which five major categories are included in materials testing?

Materials testing involves measuring the characteristics and behavior of substances to determine their suitability for specific applications. The field is divided into the following five major categories:

• Mechanical testing: Evaluates how materials respond to physical forces and loads.
• Testing for thermal properties: Assesses how materials behave under varying temperature conditions.
• Testing for electrical properties: Measures the electrical characteristics and performance of a material.
• Testing for resistance to corrosion, radiation, and biological deterioration: Examines a material's durability against environmental and external degradation factors.
• Nondestructive testing: Uses methods such as ultrasonic echolocation to inspect the integrity of structures without damaging them.1

These categories help ensure that materials meet the rigorous standards set by organizations like the International Organization for Standardization and the American Society for Testing and Materials.1
