TS ISO 23718

TS ISO 23718 is a vocabulary standard for the terminology used in mechanical testing of metallic materials. Standards of this kind establish a common language for laboratories, manufacturers, and users so that terms such as tensile, compression, bending, hardness, and impact testing are understood consistently.

The role of mechanical testing terminology

Mechanical testing of metals is used to assess how a material behaves under applied load. A vocabulary standard clarifies the concepts behind that work, helping to keep terms such as specimen, test piece, loading rate, yielding behaviour, fracture, repeatability, and reporting terminology aligned across documents and organisations. It does not replace a test method standard; rather, it supports method standards by making the language and concepts easier to interpret and compare.

What this standard covers

According to the supplied scope, this International Standard defines the terminology used in mechanical testing of metals and provides a common basis for standards and general use. The focus is therefore on terminology, not on a single apparatus or a particular test procedure. Based on ISO 23718:2007, this TS ISO edition is useful wherever consistent wording is needed in metallurgy and mechanical testing documentation.

• Terms used in mechanical testing of metallic materials
• A common terminological basis across standards
• Consistent wording in laboratories, production, and technical documentation
• Explanation of language and concepts rather than a test method itself
