The need to confirm compliance is determined by the federal law on technical regulation No. 184-FZ. .

According to the current legislation, objects of technical regulation put into circulation in the territory of the Customs Union must meet the requirements of the relevant technical regulations of the Customs Union (TR CU).

The following technical regulations apply to railway vehicles:

• 001/2011 Technical regulation on the safety of railway rolling stock
• 002/2011 Technical regulation on the safety of high-speed rail transport
• 003/2011 Technical regulation on the safety of railway infrastructure

There are two ways of mandatory confirmation of compliance:

• - Declaration of Conformity
• - Certification

  Declaration of conformity is a form of confirmation of conformity, in which compliance with the requirements of TR TS is ensured by the applicant registering a declaration of conformity. The declaration of conformity is accepted either on the basis of the applicant's own evidence or on the basis of his own evidence and evidence obtained with the involvement of an accredited party (testing center / laboratory or certification body).

  PCertification is a form of confirmation of conformity, in which compliance with the requirements of TR CU is ensured by the presence of a certificate of conformity. In this case, product testing is carried out exclusively by the certification body / testing laboratory, as a result of which the applicant receives a certificate of conformity.

  The technical regulations define the mandatory confirmation of the conformity of the railway transport software by adopting a declaration of conformity (with the involvement of an accredited party in the tests).
