Full title and description

St ISO 2533-1975 add2-1997 rus — ISO 2533:1975/Addendum 2:1997 (Russian language edition). Title: "Standard atmosphere — Addendum 2: Extension to -5000 m and standard atmosphere as a function of altitude in feet" (Russian: "Стандартная атмосфера — Расширение до −5000 м и стандартная атмосфера в функции от высоты в футах"). This item is the Russian-language version/translation of the ISO addendum that extends the ISO 2533:1975 standard atmosphere data to lower altitudes and adds tables/functions expressed in feet.

Abstract

This addendum to ISO 2533:1975 extends the range of the ISO standard atmosphere downward to −5000 m (below mean sea level) and provides corresponding standard-atmosphere values expressed as a function of altitude in feet. It supplies tables and formulae for pressure, temperature, density and derived properties (for example speed of sound) over the extended altitude range and adds convenience tables in imperial units for users working in feet.

Scope

The addendum modifies and supplements ISO 2533:1975 by extending the defined ISO Standard Atmosphere data down to −5000 m and by presenting standard-atmosphere parameters as functions of altitude in feet. It is intended for use where calculations, testing, calibration or data processing require standardized atmospheric reference values at elevations below sea level or when imperial-unit tables (feet) are needed.

Key topics and requirements

• Extension of standard atmosphere tables and relations down to −5000 m geometric height.
• Provision of atmospheric parameters (pressure, temperature, density, dynamic properties, speed of sound) over the extended range.
• Standard atmosphere expressed as a function of altitude in feet (imperial-unit tables and conversions).
• Consistent definition and use of geopotential/geometric heights and reference base values to match ISO 2533:1975 conventions.
• Numerical tables and formulae suitable for engineering calculations, calibration and test reporting.

Typical use and users

Engineers and designers in aerospace and aeronautics, test laboratories, instrument calibration facilities, meteorological services, researchers in geophysics and atmospheric science, and organizations that process or compare atmospheric or flight-test data—especially when working at elevations below sea level or with data in feet—will use this addendum. It is also used by standards offices and document controllers preparing national translations.

Related standards

ISO 2533:1975 (base standard, "Standard atmosphere"); ISO 2533:1975/Add 1:1985 (hypsometrical tables); forthcoming ISO/DIS 2533 (revision under development). Comparable regional/national standards and historical standards (for example GOST/СССР-era standard atmosphere tables) and ICAO/WMO standard atmosphere references are also related.

FAQ

Q: What is this standard?

A: This document is ISO 2533:1975/Addendum 2 (1997), the second addendum to ISO 2533:1975 ("Standard atmosphere"), provided here in a Russian-language edition/translation. It supplements the original standard with extended tables and data.

Q: What does it cover?

A: It extends the ISO standard atmosphere data down to −5000 m and supplies standard-atmosphere values presented as functions of altitude in feet, including numerical tables and formulae for pressure, temperature, density and derived properties used in calculations and testing.

Q: Who typically uses it?

A: Aerospace engineers, test and calibration laboratories, meteorologists, researchers in atmospheric and geophysical fields, standards bodies and document translation services—anyone needing standardized atmospheric reference data at low elevations or in imperial units.

Q: Is it current or superseded?

A: The addendum was published in November 1997 and remains a published part of ISO 2533:1975. The ISO committee has been developing a revised ISO 2533 (ISO/DIS 2533) which is intended to replace the 1975 edition and its addenda; users should check the status of ISO/DIS 2533 and national adoptions before assuming the 1975 edition plus addenda is the latest authoritative text for new work.

Q: Is it part of a series?

A: Yes — this is Addendum 2 to ISO 2533:1975. It complements Addendum 1 (1985) and the base ISO 2533:1975 standard; all are maintained by ISO/TC 20/SC 6 (Standard atmosphere).

Q: What are the key keywords?

A: standard atmosphere, ISO 2533, addendum, altitude in feet, extension to −5000 m, atmospheric tables, aerospace, calibration, Russian translation.
