TS 2908 ISO 31-13

TS 2908 ISO 31-13 is a terminology-focused standard for the names and symbols of quantities and units used in solid state physics. It helps keep technical notation consistent across measurement practice, publications, and engineering documentation, so that the same physical concept is represented in a clear and uniform way. In materials science, semiconductor work, and condensed matter physics, that consistency is especially important because many closely related quantities appear side by side.

Why the terminology matters in solid state physics

Solid state physics deals with the structure and properties of solids, including crystalline order, electronic states, charge transport, magnetic behaviour, and thermal effects. In such a field, precise naming and symbol use reduce ambiguity between related concepts such as density-type quantities, energy-related quantities, and transport parameters. More generally, standardized symbols make formulas easier to read, compare, and exchange between textbooks, laboratory notes, reports, and data systems.

What this part covers

• It covers the names and symbols for quantities associated with solid state physics.
• Its focus is terminology and notation rather than experimental procedures.
• It supports consistent use of quantities and units within the broader SI framework.
• This entry is based on ISO 31-13:1992 with Amendment 1 and is recorded as withdrawn.

In practical terms, the document supports the language of the discipline more than the physics itself. For engineers, researchers, and educators working with solid-state topics, its value is in making symbols and quantity names easier to interpret consistently across different technical sources.
