GOST 12.2.007.6-93 PDF

Full title and description

GOST 12.2.007.6-93 — System of labor safety standards. Electrical switching devices for voltages up to 1000 V. Safety requirements. The standard establishes safety requirements for the design, construction and safe operation of low-voltage switching apparatus intended for use on systems with nominal voltages up to 1000 V.

Abstract

This standard specifies mandatory safety requirements for electrical switching apparatus rated for voltages up to 1000 V, covering electrical safety, fire safety, ecological and hygienic aspects, constructive and technical requirements, marking and documentation, and verification/testing procedures. It is intended to reduce occupational hazards associated with manufacture, installation, operation and maintenance of such apparatus.

General information

• Status: Historically in force in the GOST/SSBT system; catalogues list it as applied in the EAEU while some registries note it as withdrawn/obsolete in favor of later harmonized regulations.
• Publication date: Approved 30 December 1994; commonly listed with an introduction/effective date in 1995–1996 (introduced 1 January 1996 in several catalogues).
• Publisher: Adopted within the interstate (GOST) system and published/distributed by national standards bodies and commercial standards publishers (Belstandart and related publishers are recorded as approval/issuance bodies).
• ICS / categories: Occupational safety / industrial hygiene and electrical engineering (ICS entries commonly show classification under occupational safety and low-voltage switchgear/controlgear).
• Edition / version: Designation - GOST 12.2.007.6-93 (1993 designation / approved end of 1994 and introduced mid-1990s).
• Number of pages: Varies by publication/translation (commonly shown as 8–14 pages depending on the issued file or translation).

Scope

The standard applies to switching electrical apparatus (commutators, contactors, starters, relays and similar devices) intended for nominal system voltages up to 1000 V (see cross-reference to GOST 12434 for device classification). It sets requirements for safe design, protective measures against electric shock, fire-hazard mitigation, materials and marking, plus requirements for instructions and tests to confirm compliance. It is focused on occupational safety and safe use in industrial and commercial environments.

Key topics and requirements

• General safety provisions and definitions (scope, normative references, classification of apparatus).
• Electrical safety requirements: insulation, clearances, creepage distances, protective earthing and bonding, requirements for accessible live parts and covers.
• Contact and switching system requirements: contact design, arc management, switching duty considerations and prevention of inadvertent operation.
• Fire safety: materials, thermal stability, prevention of ignition sources and requirements for enclosures.
• Ecological and hygienic requirements: selection of non-toxic materials, limits on hazardous substances in components and considerations for maintenance and disposal.
• Constructive and technical requirements: mechanical strength, protection from external influences (IP/IK considerations where applicable), mounting and terminal arrangements.
• Marking, documentation and user instructions: required marking, safety warnings and minimum content of technical and installation documentation.
• Verification and testing: type tests, routine checks and tests after repairs to demonstrate conformity with safety requirements.

Typical use and users

Primary users are manufacturers and designers of low-voltage switching apparatus, conformity assessment and certification bodies, safety engineers, test laboratories, electrical equipment installers and maintenance personnel. The standard is used to define design safety criteria, prepare technical documentation, perform safety assessments and support certification or regulatory compliance activities in jurisdictions that reference or formerly referenced this GOST.

Related standards

Commonly cross-referenced documents include GOST 12434 (classification of electrical apparatus), earlier version GOST 12.2.007.6-75 (the standard replaced by the 1993 edition), and a range of national/adopted standards harmonized with IEC/EN low-voltage switchgear safety standards (for example, later references point to EN/IEC 60947 series and regional technical regulations for low-voltage equipment). The standard is also cited in standards and technical regulations dealing with machine safety and specific industry equipment.

FAQ

Q: What is this standard?

A: GOST 12.2.007.6-93 is a GOST-designated occupational safety standard that defines safety requirements for electrical switching apparatus rated for voltages up to 1000 V, covering design, protective measures and testing.

Q: What does it cover?

A: It covers electrical safety (insulation, earthing, protection of live parts), contact and switching design, fire- and eco-hygienic requirements, constructive and technical requirements, marking and documentation, and type/routine testing needed to demonstrate conformity.

Q: Who typically uses it?

A: Manufacturers, design engineers, conformity assessment and certification bodies, safety and maintenance personnel, and regulatory authorities in regions that reference GOST standards.

Q: Is it current or superseded?

A: Catalogues and registries vary: the standard was approved in the mid‑1990s and has been widely used historically; some official catalogues list it as applied in the EAEU while other records indicate it was withdrawn or its direct application limited after newer regional technical regulations and harmonized (IEC/EN) standards were adopted (registries note term of validity entries through 2016 in some listings). Users should check the current national/regional regulatory framework to determine if this GOST is accepted, superseded or replaced for their jurisdiction.

Q: Is it part of a series?

A: Yes — it belongs to the System of Labor Safety Standards (SSBT / GOST 12 series) and is related to other GOSTs that cover specific equipment groups and broader electrical safety topics; it also replaces an earlier edition (GOST 12.2.007.6-75) and is linked conceptually to later harmonized documents (EN/IEC series) used for low-voltage switchgear safety.

Q: What are the key keywords?

A: Switching apparatus, low-voltage, 1000 V, electrical safety, occupational safety, switchgear, contacts, insulation, earthing, marking, testing.
