Full title and description

TR TS 004/2011 — Technical Regulation of the (Customs) Union "On safety of low‑voltage equipment" (often referenced as TR CU 004/2011 or TP TC 004/2011). The regulation establishes mandatory safety requirements, conformity assessment rules and marking provisions for low‑voltage electrical equipment placed on the common market of the Customs Union / Eurasian Economic Union.

Abstract

This technical regulation sets essential safety objectives and specifies conformity assessment procedures for electrical equipment whose rated voltages fall within the low‑voltage range (nominally up to approximately 1 000 V AC and up to 1 500 V DC, with specific limits and exceptions detailed in the text). It defines which product groups are subject to mandatory certification or declaration, marking (EAC), documentation, and labeling requirements for circulation in member states.

General information

• Status: Adopted and implemented regulation; actively used as the low‑voltage safety regulation for the Customs Union / EAEU market (subject to later amendments and updated lists of referenced standards).
• Publication date: Adopted by Decision of the Commission of the Customs Union No. 768 on 16 August 2011; entry into force on the common market from 15 February 2013 (see text and implementing decisions).
• Publisher: Commission of the Customs Union / Eurasian Economic Commission (EEC) — the regulatory body responsible for Technical Regulations of the Union.
• ICS / categories: Electrical engineering and product safety for low‑voltage equipment (relates to ICS electrical engineering groups covering low‑voltage apparatus, switchgear, wiring accessories and safety).
• Edition / version: TR CU (TR TS) 004/2011 — original decision Aug 16, 2011; later amended and updated by subsequent Council / Commission decisions (see amendments and updated lists of standards).
• Number of pages: Official regulation text and consolidated English/Russian versions are compact (commonly delivered as a short consolidated PDF — typical extracts found online are around 10–20 pages depending on included annexes and lists).

Scope

Applies to low‑voltage electrical equipment placed on the market of the Customs Union / EAEU and intended for operation within the nominal voltage ranges defined in the regulation (equipment intended for household and professional use, components such as cables, protective devices, distribution apparatus, certain tools and appliances). The regulation also lists explicit exclusions (for example equipment for explosive atmospheres, certain transport equipment, some medical devices and equipment already covered by other technical regulations) and specifies which product groups require certification versus declaration.

Key topics and requirements

• Safety objectives and essential requirements for design and construction to prevent electric shock, fire and other hazards associated with low‑voltage equipment.
• Voltage ranges and product classification criteria defining applicability (AC and DC limits and exceptions).
• Conformity assessment procedures (declaration or mandatory EAC certification for listed products), including schemes for single‑batch, serial production and factory certification.
• Marking, labeling and accompanying documentation requirements (manufacturer/importer identification, model/type, technical parameters and safety instructions; EAC marking for compliant products).
• Lists of referenced standards and test methods (annexed lists are periodically updated by EEC decisions — manufacturers must use the applicable consolidated lists).
• Transitional and amendment provisions: the regulation has been amended since 2011 and related lists of standards and testing methods have been revised by later Commission/Board decisions.

Typical use and users

Manufacturers, importers, conformity assessment bodies, testing laboratories and regulatory compliance teams placing low‑voltage electrical equipment on the market in EAEU member states (Russia, Belarus, Kazakhstan, Armenia, Kyrgyzstan and others) use this regulation to determine applicable safety requirements, testing and certification pathways (EAC). Product managers and compliance engineers rely on it to prepare technical files, choose standards for testing and ensure correct marking and documentation. Certifying bodies and market surveillance authorities use it as the legal basis for EAC conformity procedures and enforcement.

Related standards

The regulation references a broad list of national and international standards (GOST, EN/IEC) that provide detailed technical safety and test requirements for specific product groups (cables, lighting, household appliances, switchgear, portable tools, etc.). The lists of standards and test methods are maintained and updated by the Eurasian commission; manufacturers should consult the current consolidated lists when preparing conformity evidence.

FAQ

Q: What is this standard?

A: TR TS 004/2011 (also referenced as TR CU 004/2011) is a technical regulation adopted by the Customs Union / Eurasian Economic Commission that sets mandatory safety requirements and conformity assessment rules for low‑voltage electrical equipment placed on the Union market.

Q: What does it cover?

A: It covers safety requirements, conformity assessment (certification or declaration), marking (EAC), documentation and testing obligations for specified groups of low‑voltage electrical equipment operating within the regulation's nominal voltage limits, while listing product categories that are excluded or covered by other technical regulations.

Q: Who typically uses it?

A: Manufacturers, importers, testing laboratories, notified/conformity bodies, certification consultants and national market surveillance authorities working with electrical equipment for EAEU member states.

Q: Is it current or superseded?

A: The 2011 regulation is active but has been amended and supplemented by later EEC/Commission decisions (updated lists of referenced standards and clarifications have been issued in subsequent years). Stakeholders must consult the latest consolidated texts and EEC decisions to ensure they use the currently applicable requirements and referenced standards.

Q: Is it part of a series?

A: Yes — it is one of the set of Customs Union / EAEU technical regulations on product safety (for example TR CU 020/2011 on EMC, TR CU 010/2011 on machinery safety, TR CU 037/2016 on restriction of hazardous substances, etc.). Compliance with multiple technical regulations may be required for many electrical products.

Q: What are the key keywords?

A: Low‑voltage, electrical safety, TR TS 004/2011, TR CU 004/2011, EAC, conformity assessment, certification, declaration, marking, GOST/IEC standards.
