DIN EN ISO 80000-12 2020-02 PDF

Full title and description

STB DIN EN ISO 80000-12 2020-02 — Quantities and units — Part 12: Condensed matter physics. This entry represents a national adoption (DIN/EN) of the ISO 80000-12 international standard, which gives standardized names, symbols, definitions and units used in condensed-matter/solid-state physics.

Abstract

This standard specifies names, recommended symbols, definitions and units for quantities encountered in condensed matter physics. Where appropriate it also gives conversion factors and recommends conventions for presenting physical quantities and symbols in technical documents and publications. The content conforms to the ISO 80000 family on quantities and units.

General information

• Status: National adoption of EN/ISO; registries indicate the DIN/EN adoption record dated 2020-02; some listings show the 2020 national entry as withdrawn while the international ISO 80000-12:2019 remains published.
• Publication date: National listing: 01 February 2020 (2020-02); International ISO edition published August 2019 (ISO 80000-12:2019).
• Publisher: National adoption published under DIN/EN (national body) as an adoption of the ISO document; original international publisher: ISO.
• ICS / categories: 01.060 — Quantities and units.
• Edition / version: National adoption (2020-02) of ISO 80000-12:2019 (Edition 2, 2019); corrected versions of the ISO text were issued (corrected version 2021-11) and amendment activity has been recorded.
• Number of pages: International ISO 80000-12:2019 lists 15 pages; some national product entries for DIN/EN adoption list a 31‑page document (national formatting and front/back matter can change page count).

Scope

The standard provides standardized names, symbols, definitions and units for quantities used in condensed matter (solid state) physics. It is intended to harmonize notation and units across technical publications, specifications and measurement reports in condensed-matter research and engineering. The scope covers commonly used quantities in the field and related conversion factors where appropriate.

Key topics and requirements

• Standardized names and recommended symbols for condensed-matter quantities (for example lattice parameters, density of states, Fermi energy, mobility, resistivity, magnetic moment and related quantities).
• Definitions and precise unit assignments to ensure consistency with the SI and the broader ISO 80000 series.
• Guidance on notation, typographical conventions and use of sub- and superscripts for indices and quantities in formulas.
• Conversion factors and numerical relationships where non-SI units or derived forms commonly appear in condensed-matter contexts.
• Alignment with other parts of the ISO 80000 family to ensure coherent cross-part usage of symbols and units.

Typical use and users

Researchers and engineers in condensed matter and materials physics, technical editors preparing scientific and standards documents, metrology and calibration laboratories, publishers of scientific literature, and standards committees that prepare or adopt technical specifications for measurements and reporting. The standard is used where consistent symbol/units practice is required across organizations and publications.

FAQ

Q: What is this standard?

A: It is the national adoption entry (STB / DIN EN ISO 80000-12 2020-02) of the international standard ISO 80000-12, which defines quantities, names, symbols and units used in condensed matter (solid state) physics.

Q: What does it cover?

A: It covers recommended names, symbols, definitions and units for physical quantities commonly used in condensed matter physics and provides guidance to ensure consistency with the SI and the ISO 80000 series.

Q: Who typically uses it?

A: Physicists, materials scientists, standards writers, technical editors, metrology labs and publishers who need consistent notation and units in condensed-matter science and engineering documents.

Q: Is it current or superseded?

A: The international ISO 80000-12:2019 is the current ISO edition (with a corrected version issued in 2021 and amendment activity recorded). National adoption entries (such as the 2020-02 DIN/EN listing) may have been managed separately and some registries show the national record as withdrawn; always check the issuing national standards body for the authoritative current status.

Q: Is it part of a series?

A: Yes — it is Part 12 of the ISO 80000 series “Quantities and units,” which contains multiple parts addressing general rules and domain-specific quantities and units.

Q: What are the key keywords?

A: Condensed matter, solid state physics, quantities and units, symbols, SI, ISO 80000, notation.
