Full title and description

ГОСТ 20.57.406-81 — Комплексная система контроля качества. Изделия электронной техники, квантовой электроники и электротехнические. Методы испытаний (Complex quality control system — electronic, quantum electronic and electrotechnical components — test methods). Этот межгосударственный стандарт устанавливает систему видов и методов испытаний для оценки стойкости изделий электронной и электротехнической промышленности к механическим, климатическим, биологическим воздействиям и специальным средам.

Abstract

GOST 20.57.406-81 defines a unified set of test methods and numbering for tests applied to electronic, quantum-electronic and electrotechnical products. It covers environmental (temperature, humidity, pressure), mechanical (vibration, shock, impact), biological (mold) and special-media (salt spray, solvents, solar radiation) test procedures and criteria for assessing conformity to design and technical requirements. The standard was introduced as a system-level reference used by manufacturers and test laboratories.

General information

• Status: Introduced and widely used as a system of test methods since its approval in 1980; registry records are mixed (catalogs list it as active in many databases, while some commercial catalogs list a withdrawal/termination entry).
• Publication date: Date of introduction — 01 January 1982 (approved by USSR standards committee 13 November 1980).
• Publisher: ИПК «Издательство стандартов», Moscow (original publisher for the official text).
• ICS / categories: Related classifications include electronic component assemblies and quality management / assurance (examples in catalogs: 31.190; 03.120.10).
• Edition / version: Original designation ГОСТ 20.57.406-81 (1981) with multiple amendments published over the 1980s–1990s (amendments and corrected eds are recorded in document histories).
• Number of pages: Approximately 132–133 pages in typical printed/electronic copies.

Scope

Applies to electronic, quantum-electronic and electrotechnical products listed in the standard's annexes and establishes standardized methods to test products for resistance to mechanical stresses (vibration, shock, impact), climatic effects (temperature cycling, humidity, frost/dew), biological agents (mold), corrosive/special media (salt spray, solvents), solar radiation and related environmental factors. It is intended to be used for type, qualification, periodic and acceptance tests where referenced by product-specific standards or technical specifications.

Key topics and requirements

• Numbering scheme and designation of test types and methods used across product standards (uniform method codes and numbering).
• Mechanical tests: vibration, shock, impact, resonance identification, mounting/fixture requirements for test specimens.
• Climatic tests: thermal cycling, high/low temperature endurance, humidity (short and long exposure), frost and dew exposure, atmospheric pressure variations.
• Environmental/media tests: salt (marine) fog, solar radiation (UV), solvents and chemical exposure, static/dynamic dust and particulate exposure.
• Biological resistance: procedures for mold/fungal exposure and evaluation criteria.
• Test sequencing, selection of test samples (prototype, production samples), acceptance criteria and reporting rules for evaluating conformity with technical requirements.
• References and alignment notes to comparable SEV/IEC/SOV standards and cross-references used for terminology and climatic conditions.

Typical use and users

Used by test laboratories, certification bodies, manufacturers and design engineers of electronic and electrotechnical equipment for type and qualification testing, routine quality assurance, acceptance testing and environmental qualification. Also referenced in product-specific GOSTs and industry technical conditions (TU) when environmental and mechanical robustness must be demonstrated.

Related standards

The standard contains numerous normative references and alignment notes to other national and inter-state documents (examples include GOST 15150, GOST 9.048, related GOST R/РВ documents and SEV/IEC equivalents referenced in annexes). It is commonly cited by product standards that require environmental and mechanical testing for electronic and electrotechnical items.

Keywords

FAQ

Q: What is this standard?

A: ГОСТ 20.57.406-81 is an intergovernmental (GOST) system-level standard that defines a comprehensive set of test methods and a numbering/designation system for environmental, mechanical, biological and special-media tests applied to electronic, quantum-electronic and electrotechnical products.

Q: What does it cover?

A: It covers methods and procedures for vibration, shock and impact testing; temperature and humidity cycling; exposure to pressure changes; salt/fog and chemical media; solar radiation and fungal exposure; specimen preparation, test sequencing and criteria for conformity assessment.

Q: Who typically uses it?

A: Test laboratories, product certifiers, manufacturers of electronic and electrotechnical equipment, and design/quality engineers use the standard when environmental and mechanical robustness must be validated or when product-specific standards reference these general test methods.

Q: Is it current or superseded?

A: The standard was introduced into force on 01 January 1982 (approved 13 November 1980). Catalog records vary by registry: many technical databases and suppliers still present the standard as the reference document (with recorded amendments), while some commercial catalogs show a withdrawal/termination note (example entry with terms of validity listed to 01 September 2014). Users should check national/regulatory registries or official standards bodies for the current legal/regulatory status in their jurisdiction.

Q: Is it part of a series?

A: Yes — it is a system document within the broader series of GOSTs addressing quality control and environmental testing for electronic and electrotechnical products; it provides general test-methods that are referenced by numerous product-specific GOSTs and regional SEV/IEC-mapped documents. Annexes list corresponding SEV standards and normative cross-references.

Q: What are the key keywords?

A: Quality control, test methods, environmental testing, vibration, shock, thermal cycling, humidity, salt spray, solar radiation, mold resistance, electronic components.
