Technical Regulation TR CU 004/2011

The technical regulation TR CU 004/2011 “on the safety of low voltage equipment” establishes minimum requirements on electrical equipment with regard to life, health, property, environmental and consumer protection, in order to protect against information that may be inaccurate.

In accordance with Regulation TR CU 004/2011, equipment must be manufactured in accordance with and protected against:

  • Hot;
  • Mechanical injuries;
  • Shocks;

In order to be approved and placed on the Russian and Eurasian markets, the products must comply with the requirements of Technical Regulation TR CU 004/2011. And although they have been accorded the requirements of the Low Voltage Directive 2014/35/EU, the requirements of Technical Regulation TR CU 004/2011 and 2014/35/EU are not the same.

To deliver electrical equipment to customs union countries, you need two standard documents:

  • TR CU R – U 004/2011 “On the safety of low voltage equipment”. It refers to electrical products intended for use at rated voltages of 50 up to 1000 V alternating current and 75 up to 1500 V direct current;
  • TR CU R- U 020/2011 “electromagnetic compatibility of technical means”, with reference to technical products that may cause electromagnetic inference and/or quality of operation of which exposure to external electromagnetic disturbances depends on apart from technologies with passive electromagnetic compatibility or used by manufacturers in other technical resources.

Scope of application of TR CU 004/2011

This technical regulation is to be applied to all low-voltage equipment, intended for alternating current from 50 to 1000 volts and direct current from 75 to 1500 volts. EAC certificates require an applicant, i.e. a legal person registered in the territory of the customs union.

According to the regulation, they are subject to EAC certification;

  • Cables;
  • Power tools;
  • Electrical distributors;
  • Electronic musical instruments;
  • Circuit breakers and safety switches;
  • Household appliances;
  • Devices that can be connected to machines for electronic data processing;
  • Electrical control unit;
  • Personal data processing machines.

All low-voltage equipment that is not on the above list of devices subject to certification is subject to the mandatory declaration in accordance with TR CU 004/2011.

Instead, they do not require any proof of compliance:

  • Electrical equipment for lifts;
  • Electrical equipment for land, air and water transport;
  • Electrical equipment for the safety systems of nuclear reactor plants;
  • ATEX equipment;
  • Military technology;
  • Medical technology;
  • Control devices for electric fences.

It should be borne in mind that, although products may or may not be subject to conformity assessment under TR CU 004/2011, they are also potentially subject to conformity assessment under other directives such as:

  • TR CU 010/2011 on the safety of machinery and equipment;
  • TR EAEU 037/2016 on the restriction of the use of certain hazardous substances in electrical and electronic equipment;
  • TR CU 020/2011 on electromagnetic compatibility.

The format of the Customs Union certificate is unified for all five Member States of the Union.

 Documents required for  certificate TR CU 004

The documents required for the TR CU 004 certificate are:

  • The user and maintenance manual;
  • Security justification;
  • Application for certification;
  • Technical description of all declared products;
  • Copy of the valid contract with the local representative;
  • Test reports on the equipment carried out by the manufacturer, a person authorized by the manufacturer or/and an accredited test laboratory (if available);
  • ISO 9001:2008 (if available).

How to obtain the certificate

The procedure for issuing the certificate can be carried out in different ways.
The document can be obtained either for serial products or for a single shipment, depending on the number of products that the manufacturer exports to the Customs Union.
Some groups of products are subject to mandatory testing in specially accredited SERCONS laboratories for the certificates to be issued.
Foreign manufacturers must submit a package of documents that includes:

  • The detailed technical description of the product;
  • The address of the manufacturer;
  • The manual or guide to operating the product;
  • The contract for the supply of the products and the delivery receipt (if it is the certification for a single shipment);
  • The name of the product;
  • The Customs Tariff Code.
