Reliability in technics. Dependability requirements: contents and general rules for specifying
Full title and description
GOST 27.003-90 — "Reliability in technics. Dependability requirements: contents and general rules for specifying". The standard sets out the structure and general rules for formulating dependability (reliability) requirements for inclusion in normative-technical and design documentation for products.
Abstract
GOST 27.003-90 provides a unified framework for defining dependability requirements (such as life, failure rates, maintainability and availability parameters) that designers, manufacturers and technical document authors must include in product specifications and technical documentation. It applies across product types and aims to standardize how reliability-related demands are expressed in normative and design documents.

- Publication date: Original approval dated 29 December 1990; effective/introduced 01 January 1992.
- Publisher: State Committee for Standards of the USSR (Gosstandart); developed by the State Committee for Quality Management of the USSR and standards bodies.
- ICS / categories: 03.120.01 (Quality in general); 21.020 (Characteristics and design of machines, apparatus, equipment).
- Edition / version: Designation GOST 27.003-90 (1990). Later replaced by GOST 27.003-2016.
- Number of pages: Approximately 19–20 pages (commonly listed as 20 pages in commercial catalogs).
Scope
The standard applies to all kinds of products and establishes the composition, sequence and general rules for setting dependability (reliability) requirements to be included in normative-technical and design documentation. It is intended to be used when drafting technical specifications, design requirements, acceptance criteria and related documentation where dependability parameters must be defined.
Key topics and requirements
- Structure and required content of dependability (reliability) requirements for technical and design documentation.
- General rules for formulation of requirements (how to state parameters, units, and conditions of use/test for dependability metrics).
- Typical dependability parameters and indicators to be specified (operational life, mean time between failures (MTBF) / failure rate, maintainability, availability, repair times, resource/life limits).
- Requirements for linking dependability demands to testing, acceptance and maintenance documentation.
- Cross-references to related dependability standards and terms (for consistent definitions and methods across the GOST dependability series).
Typical use and users
Used by product designers, reliability and quality engineers, technical writers, test laboratories, procurement and certification bodies, and regulatory/standards teams who must define, verify or enforce dependability requirements in product specifications and technical documentation. It is also referenced by standards developers when preparing related normative documents.
Related standards
Closely related documents in the same dependability (reliability) series include GOST 27.002-89 (general principles and terms), GOST 27.004-85 (terms and definitions for technological systems) and other GOST 27.xxx standards. The document was later replaced by GOST 27.003-2016, which updates and consolidates rules for specifying dependability requirements.

FAQ
Q: What is this standard?
A: GOST 27.003-90 is a national (Soviet-era) standard titled "Reliability in technics. Dependability requirements: contents and general rules for specifying" that prescribes how dependability requirements should be structured and stated in technical and design documentation.
Q: What does it cover?
A: It covers the composition, order and general principles for formulating dependability (reliability) requirements — for example, what parameters to specify (life, failure rates, maintainability, availability), how to express them, and how to link them to testing and acceptance documentation.
Q: Who typically uses it?
A: Product designers, reliability/quality engineers, technical documentation authors, testing bodies and standards developers use this standard when they need to define or harmonize dependability requirements for products.
Q: Is it current or superseded?
A: GOST 27.003-90 has been superseded and is no longer current; it was replaced by GOST 27.003-2016. Many catalogs list the original as withdrawn.
Q: Is it part of a series?
A: Yes — it is part of the GOST 27 series addressing dependability/reliability in technics, which includes related standards for terms, methods of evaluation and specific requirements (e.g., GOST 27.002-89, GOST 27.004-85, etc.).
Q: What are the key keywords?
A: The primary keywords are reliability, dependability, MTBF, failure rate, maintainability, availability, technical requirements, product specification.
