Full title and description

ГОСТ 31947-2012 — "Провода и кабели для электрических установок на номинальное напряжение до 450/750 В включительно. Общие технические условия" (English title: "Wires and cables for electrical equipment of rated voltages up to and including 450/750 V. General specifications"). Этот межгосударственный стандарт устанавливает общие технические требования, классификацию, порядок испытаний, маркировку, упаковку и правила приемки проводов и кабелей низкого напряжения.

Abstract

Standard setting general technical requirements for wires and cables intended for electrical installations with rated voltages up to and including 450/750 V. Covers classification by conductor material and product type, allowable conductor cross-sections, insulation and sheath types (including low-smoke and halogen-free variants), temperature ratings, fire and toxicity limits for combustion products, testing categories (acceptance, periodic, type), marking, packaging, transportation and storage, and rules of acceptance. Designed to harmonize requirements across participating states and to be used as a basis for specific technical specifications for particular wire/cable marques.

Scope

Applies to wires and cables intended for electrical installations with nominal voltages up to and including 450/750 V. The standard establishes classification rules (by conductor material, product type, flexibility class, insulation and sheath materials), allowed conductor cross-sections, requirements for long-term operating temperatures, mechanical and electrical properties, fire behaviour (including low-smoke and halogen-free designations), limits on corrosive and toxic combustion products, sampling and testing procedures, acceptance categories (type, periodic, acceptance), marking, packaging, transportation and storage. It serves as a general specification to be supplemented by technical conditions for specific conductor/cable marques.

Key topics and requirements

• Classification of products by conductor material (copper, aluminum alloy) and by type (wires, cables, single- and multi-core) and by flexibility class.
• Permitted ranges of nominal conductor cross-sections for single- and multi-core products.
• Requirements for insulation and sheath materials, including polymer types, flame-retardant and low-smoke / halogen-free variants (designations нг‑LS, нг‑HF, and similar).
• Thermal ratings and limits for continuous conductor temperature (minimum established values, to be specified further in technical conditions for specific marques).
• Fire-safety and toxicity limits for combustion products (quantitative limits for halogen acids, conductivity, pH and toxicity indices referenced to IEC test procedures).
• Testing framework: acceptance, periodic and type tests; specified test methods and references to related IEC/GOST test standards (for example, tests for corrosive gases and combustion products per IEC 60754 series).
• Marking, labelling, packaging, transport and storage requirements consistent with broader cable/product rules (to be used together with more specific marking/packaging standards).

Typical use and users

Primary users are cable and wire manufacturers, product designers, certification and testing laboratories, regulatory authorities, procurement/specification engineers, electrical installation contractors and technical auditors who need a general framework for low-voltage cable technical requirements and conformity assessment. The standard is used to derive or check product-specific technical specifications and to harmonize product documentation for the participating states.

Related standards

Associated and referenced documents include (examples): the preceding national standard it replaced (GOST R 53768-2010), standards on marking/packaging/transportation (e.g., GOST 18690-2012), and several IEC/GOST test method standards such as those corresponding to IEC 60754 (tests for corrosive halogen-containing gases) and IEC 60851 series for conductor tests; the standard is intended to be applied alongside product-specific technical specifications.

FAQ

Q: What is this standard?

A: ГОСТ 31947-2012 is a межгосударственный (interstate) standard that provides general technical specifications for wires and cables used in electrical installations with rated voltages up to and including 450/750 V; it was approved by Rosstandart on 29 November 2012 and put into effect 1 January 2014.

Q: What does it cover?

A: It covers classification, basic parameters (conductor materials and cross-sections), insulation and sheath materials (including fire-performance classes), temperature ratings, limits on corrosive and toxic combustion products, test regimes (acceptance/periodic/type), marking, packing, transport and storage rules, and rules of acceptance — serving as a general specification to be combined with product-specific technical conditions.

Q: Who typically uses it?

A: Manufacturers of wires and cables, design and specification engineers, testing and certification laboratories, procurement and quality departments, installers and compliance authorities use the standard to define, test and verify low-voltage cable products.

Q: Is it current or superseded?

A: As published it is in force and was introduced for voluntary application in the Russian Federation from 1 January 2014. It replaced the earlier national standard GOST R 53768-2010; subsequent editorial revisions and amendments have been recorded in official and commercial annotations (users should consult the latest amendment notices or the national standards registry for the current consolidated text).

Q: Is it part of a series?

A: It is a general (umbrella) technical specification intended to be used together with product-specific technical conditions and with other GOST/IEC documents covering test methods, marking and packaging; related standards cited within include those for test methods (IEC/GOST equivalents) and for marking/packaging of cable products.

Q: What are the key keywords?

A: Wires, cables, low-voltage, insulation, sheath, low-smoke, halogen-free, marking, packaging, testing, acceptance, 450/750 V.
