GOST 27.003-2016 PDF

Full title and description

GOST 27.003-2016 — Industrial product dependability. Dependability requirements: contents and general rules for specifying. The standard (Russian title: Надежность в технике. Состав и общие правила задания требований по надежности) defines the required contents and general principles for formulating reliability (dependability) requirements to be included in normative documents and design documentation for products.

Abstract

This standard sets out the composition of reliability requirements and general rules for their specification (types of indicators, failure/limit-state criteria, methods of control and test, and documentation practices) so that consistent, measurable dependability requirements can be included in normative and design documentation across product types and industries. It is intended to harmonize how reliability requirements are formulated and applied.

Scope

The standard applies to all types of products (machines, equipment, items) and establishes the composition and general rules for specifying reliability (dependability) requirements for inclusion in normative documents (standards and technical regulations) and in design documentation. It is intended to be used wherever formalized, measurable reliability requirements must be set and verified.

Key topics and requirements

• Structure and required contents of reliability (dependability) requirements (what items must be specified in a requirements clause).
• Classification of reliability indicators (e.g., failure rates, mean time to failure/repair, probability of failure-free operation, maintainability and safety-related measures).
• Definitions of failure criteria and limit-state criteria to be used when specifying pass/fail performance benchmarks.
• Guidance on numerical requirement setting, tolerances and reference conditions for tests and measurements.
• Recommended methods of control, verification and testing for demonstrating compliance with specified reliability requirements.
• Documentation practices: how to record, present and reference reliability requirements in normative and design documentation.
• Application notes for inclusion in contracts, specifications and acceptance procedures.

Typical use and users

Used by design and development engineers, reliability and QA engineers, test laboratories, standards and regulatory bodies, procurement/specification writers, and technical document authors who must formulate, check or enforce formally specified reliability requirements for products across industrial sectors.
