GOST 21964-76 PDF

Full title and description

GOST 21964-76 — "Внешние воздействующие факторы. Номенклатура и характеристики" (English: "Environmental factors. Nomenclature and characteristics"). The standard establishes a unified nomenclature and the characteristic parameters of external (environmental) influencing factors applicable to technical products, materials and test procedures.

Abstract

GOST 21964-76 defines and classifies the external environmental factors (climatic, mechanical, chemical, biological, electromagnetic, radiative, etc.) and specifies their characteristic parameters and ranges. It is intended as a reference dictionary for tests, design, selection of test conditions and for harmonization with related interstate (СТ СЭВ) documents. The standard was approved in 1976 and first introduced into effect in 1977, and its text has been republished with amendments.

General information

• Edition / version: Original designation GOST 21964-76 (introduced 1977) with Amendments №1, №2, №3 integrated in later printings; republished editions in the 1980s–1990s.
• Number of pages: Typically listed as 29–33 pages in various catalogues (commonly cited as 31 pages in official/reprint records).

Scope

Applies as a normative reference that establishes a common nomenclature and quantitative characteristics for the external (environmental) factors that affect technical products and materials. It is intended for use in standardization, test specification, design documentation and by laboratories when defining test conditions and interpreting environmental influence criteria. The standard is also indicated as corresponding to the Comecon interstate document ST СЭВ 2603-80.

Key topics and requirements

• Classification (nomenclature) of external/environmental influencing factors (climatic, mechanical, chemical, biological, electromagnetic, radiation, etc.).
• Definition of characteristic parameters for each factor (e.g., temperature ranges, humidity, vibration amplitudes/frequencies, shock, corrosive media concentrations, irradiance, electromagnetic field levels).
• Standardized units, reference values and typical ranges to be used in test specifications and technical documentation.
• Cross-references to related testing and terminology standards to ensure consistent selection of environmental test conditions.
• Integration of approved amendments that update characteristic values and editorial clarifications.

Typical use and users

Used by standards bodies, test laboratories, product designers and manufacturers, metrology and certification authorities, procurement and quality assurance departments. Typical applications include specifying environmental test conditions, developing test programs, defining storage/transportation requirements, and harmonizing product requirements across organizations and interstate markets.

Related standards

Commonly referenced alongside and complementary to other environmental and testing standards such as GOST 15150 (climatic conditions for products), GOST 26883-86 (environmental factors — terms and definitions), GOST 24813-81 (testing from the point of view of climatic factors) and the Comecon document ST СЭВ 2603-80, among others used for test methods and equipment attestation.

FAQ

Q: What is this standard?

A: GOST 21964-76 is a Soviet-era national standard titled "Environmental factors. Nomenclature and characteristics" that defines a unified list and the characteristic parameters of external factors relevant for technical products and testing.

Q: What does it cover?

A: It covers the classification and quantitative characteristics (ranges, units, reference values) of environmental factors — climatic, mechanical, chemical, biological, electromagnetic and radiative — used when specifying test and operating conditions for products and materials.

Q: Who typically uses it?

A: Product designers, test laboratories, standards and certification bodies, manufacturers and quality assurance teams use it as a normative reference when defining environmental test conditions, selection of test equipment, and preparing technical documentation.

Q: Is it current or superseded?

A: Catalogues and standards repositories list GOST 21964-76 with its integrated amendments and reprints and do not universally mark it as withdrawn; it is commonly treated as a reference document (with some national/regional standards and later GOST/R documents providing updated test-method detail). Users should verify the current legal/mandatory status for their country and application in an official standards registry.

Q: Is it part of a series?

A: It is part of the general body of GOST documentary system for environmental and testing terminology and is linked to related standards (terminology and test procedures) and to the Comecon interstate document ST СЭВ 2603-80; it functions as a normative nomenclature/dictionary used across multiple testing and product standards.

Q: What are the key keywords?

A: Environmental factors; nomenclature; characteristics; climatic testing; external influences; test conditions; GOST 21964-76; ST СЭВ 2603-80.
