标准2025千克是何时制定的？如何准确测量光谱？如何在热力学中做到准确测量？量和单位的一致性是准确测量的核心，只有人人使用同一种测量语言，才能做到准确测量。ISO/IEC 80000系列标准的作用就在于此，目前该系列标准正在修订中。ISO / IEC 80000数量和单位系列在国际称重和测量局（BIPM）关于国际单位制的指南（称为SI手册）中提及，因此为数量和单位的定义提供了重要支持
ISO/IEC 80000量和单位系列标准参照了国际法制计量局（BIPM）关于国际单位制指南（称为SI手册）中提及，因此为量和单位的定义提供了重要支持。ISO/IEC 80000量和单位系列标准共有13个部分，其中11个部分来自国际标准化组织（ISO），还有2部分来自国际电工委员会（IEC），很多部分都与最终修订版十分接近。
该系列包括术语、定义、建议符号、单位以及科学、工程、计量和工业方面量的重要信息，为学科和技术文件、教科书、标准和指南编写者提供了有效参考。
ISO/TC 12量和单位技术委员会主席Leslie Pendrill教授负责该系列的ISO部分，技术委员会工作组召集人Michael Krystek博士负责工作组修订部分，同时参与了SI手册的修订，以此确保手册与系列标准相对应。
Pendrill教授说：“量和单位的系统一致，比如ISO/IEC 80000系列标准，有助于销售创新产品和一切服务。”
Pendrill教授还表示：“随着统一测量在全球贸易、制造业、能源产品和健康等各领域中的需求增加，我们修订审查标准非常重要，确保测量都高度相关与准确，符合国际单位制标准。”
ISO/IEC 80000系列标准加强了科学和工程领域中术语、定义和符号的国际统一，确保了统一的测量语言和公式书写。该系列标准减少了错误的风险，有助于促进各领域科学家和工程师的相互交流。
该标准将应用于计量技术研究所、学术机构、技术书籍作者和翻译者、标准制定者以及各工业领域。
目前，该标准其中很大一部分正处于国际标准草案（DIS）阶段，将于近期出版：
ISO 80000-2, 数学
ISO 80000-4, 力学
ISO 80000-5, 热力学
ISO 80000-7, 光和辐射
ISO 80000-10, 原子和核物理学
ISO 80000-12, 凝聚态物质物理学
另外，ISO 80000-9，物理化学和分子物理学，和ISO 80000-11，特征数，近期已经进入国际标准草案（DIS）阶段，意味着相关方在最终版之前还能再一次提交反馈。量和单位系列的其他部分如下：
ISO 80000-1, 总则
ISO 80000-3, 空间和时间
IEC 80000-6, 电磁学
ISO 80000-8, 声学
IEC 80000-13, 信息科学和技术
修订版第1部分、第3部分和第8部分将于今年进入国际标准草案（DIS）阶段。
ISO/IEC 80000系列标准的ISO部分将由ISO/TC 12补充修订，量和单位的秘书处由瑞典标准化协会（SIS）承担。
Making it all add up – International Standards for quantities and units are under revision
When is a kilogramme a kilogramme? How do you accurately measure the spectrum of light? How do you correctly measure in thermodynamics? Consistency in quantities and units is essential for accurate measurement and can only be achieved if everyone is using the same language. The ISO/IEC 80000 series of standards does just that, and it is currently under revision.
The ISO/IEC 80000 quantities and units series is referenced in the International Bureau of Weights and Measurements (BIPM)’s guide on the International System of Units, known as the SI brochure, and thus provides important support for the definition of quantities and units. It consists of 13 different parts, featuring 11 from ISO and two from the International Electrotechnical Commission (IEC), some of which are approaching a crucial and final stage of their revision.
The series gives terms, definitions, recommended symbols, units and any other important information related to quantities used in science, engineering, metrology and industry. It is a reference for those writing scientific or technical documents, textbooks, standards and guides.
Prof. Leslie Pendrill, Chair of ISO/TC 12, Quantities and units, the technical committee (TC) responsible for the ISO parts in the series, and Dr Michael Krystek, Convenor of the TC’s working group in charge of their revision, are also involved in the revision of the SI brochure to ensure that the standards correspond.
“Harmonized treatment of quantities and units, as presented in the ISO/IEC 80000 series, will facilitate the route to market for innovative products and services of all kinds,” said Prof. Pendrill.
“With increasing demands for unified measurement in many areas, such as global trade, manufacturing, energy production and health, it is important we revise and check the standards to ensure they are as relevant and accurate as possible, and aligned with the International System of Units.”
The ISO/IEC 80000 series of standards underpins the international harmonization of terms, definitions and symbols used in science and engineering and thus guarantees a unified language and writing of formulae. It reduces the risk of error and facilitates and encourages communication between scientists and engineers of many disciplines.
The standards are expected to be used by metrology and technical institutes, academia, technical book writers and translators, standards developers and many areas of industry.
A number of the parts are currently at Draft International Standard (DIS) stage and approaching publication. They are:
. ISO 80000-2, Mathematics
. ISO 80000-4, Mechanics
. ISO 80000-5, Thermodynamics
. ISO 80000-7, Light and radiation
. ISO 80000-10, Atomic and nuclear physics
. ISO 80000-12, Condensed matter physics
In addition, ISO 80000-9, Physical chemistry and molecular physics, and ISO 80000-11, Characteristic numbers, have recently reached DIS stage, meaning interested parties can once more submit feedback on the draft before final publication. The other parts in the series on quantities and units are:
. ISO 80000-1, General
. ISO 80000-3, Space and time
. IEC 80000-6, Electromagnetism
. ISO 80000-8, Acoustics
. IEC 80000-13, Information science and technology
The revision of Parts 1, 3 and 8 should reach DIS stage some time later this year.
The ISO parts of the ISO/IEC 80000 series of standards are being developed by ISO/TC 12, Quantities and units, whose secretariat is held by SIS, the ISO member for Sweden. The series can be purchased from your national ISO member or through the ISO Store or the IEC Store.
