ISO 31

ISO 31 was an international standard that provided a set of rules and recommendations for the use of quantities, units, and their symbols within various fields of science and engineering. Issued by the International Organization for Standardization (ISO), it aimed to create a consistent framework for expressing measurements, promoting clarity and reducing misunderstandings in scientific communication.

ISO 31-0 is part of a series of international standards published by the International Organization for Standardization (ISO) that deal with quantities and units. Specifically, ISO 31-0 provides general principles related to quantities and units used in science and technology. The standard serves as a guideline for the definition and use of physical quantities and their respective units, and it encompasses aspects such as the notation and the concepts related to measurement.

ISO 31-1 is an international standard that pertains to the nomenclature and symbols used in the field of physics. Specifically, ISO 31-1 provides guidelines for the representation of physical quantities and the symbols that are used to express them. This standard is part of a larger series, ISO 31, which covers various aspects of physical measurements and related concepts. ISO 31-1 is focused on the general principles and definitions applicable to physical quantities and their units.

ISO 31-11 is a part of the ISO 31 series, which provides standards for quantities and units in various scientific and technical fields. Specifically, ISO 31-11 relates to quantities and units in the field of "Physical Chemistry." ISO 31-11 covers the units and quantities relevant to thermodynamics and physical chemistry, including concepts such as temperature, pressure, concentration, chemical potential, and more.

ISO 31-3 is part of the ISO 31 standard, which pertains to the international system of units and their application in quantitative information. Specifically, ISO 31-3 deals with the quantities and units related to mechanics. This standard outlines the definitions, symbols, and units for various mechanical quantities, such as force, mass, energy, power, and pressure, among others.

ISO 31-4 is an international standard that was part of the ISO 31 series, which deals with physical quantities and units. Specifically, ISO 31-4 addresses the topic of "Thermodynamics". It provides definitions and recommendations for the units of measurement used in thermodynamics, such as temperature, heat, and energy.

ISO 31-5 is part of the ISO 31 series of international standards that address the symbols and units of measurement used in various scientific and technical fields. Specifically, ISO 31-5 pertains to the area of "Physics" and provides standardized symbols and units for quantities related to mechanics, specifically relating to force, mass, energy, and related parameters.

ISO 31-6 is part of the ISO 31 series, which is a standard that provides rules and guidelines for the use of symbols and units of measurement in various fields, particularly in science and technology. Specifically, ISO 31-6 focuses on "Units of Quantity and Their Symbols." This part of the ISO standard deals with the particular units and symbols used to represent physical quantities.

ISO 31-7 is part of the ISO 31 series of international standards that deal with physical quantities and units. Specifically, ISO 31-7 addresses the topic of "Specific quantities and units" related to the field of mechanics. It lists various mechanical quantities and their corresponding units, providing a standardized framework for measurements and ensuring consistency in scientific communication.

ISO 31-8 is a part of the ISO 31 series of standards which deals with physical quantities and units. Specifically, ISO 31-8 pertains to the field of "Electromagnetism." This standard defines the terms and symbols used to express various electromagnetic quantities and outlines the units for measuring them. The ISO 31 series was developed to provide a coherent and standardized approach to scientific and technical documentation, ensuring consistency in the use of measurement units across different disciplines.
