▍What is GOST-R Declaration?

GOST-R Declaration of Conformity is a declaration document to prove goods are complied with Russian safety regulations. When the Law of Product and Certification Service was issued by Russian Federation in 1995, compulsory product certification system came into force in Russia. It requires all products sold in Russian market to be printed with GOST mandatory certification mark.

As one of methods of mandatory conformity certification, Gost-R Declaration of Conformity bases on inspection reports or quality management system certification. In addition, Declaration of Conformity has the characteristic that it can only be issued to a Russian legal entity which means the applicant (holder) of the certificate can only be a Russian officially registered company or foreign office that registered in Russia.

▍GOST-R Declaration Type and Validity

1. Single Shipment Certificate

Single shipment certificate is only applicable to specified batch, specified product stipulated in a contract. Specific information is strictly under control, such as item name, quantity, specification, contract and Russian client.

2. Certificate with validity of one year

Once a product is granted the certificate, manufacturers can export products to Russia within 1 year without limit of shipment times and quantities to specific client.

3. Certificate with validity of three/five years

Once a product is granted the certificate, manufacturers can export products to Russia within 3 or 5 years without limit of shipment times and quantities to specific client.

▍Why MCM?

●MCM possesses a group of engineers to study Russian latest regulations, ensuring latest GOST-R certification news can be shared accurately and timely with clients.

●MCM builds close cooperation with the local the earliest-established certification organization, providing stable and effective certification service for clients.

▍What is EAC?

According to The Relevant Common Criteria and Rules of Technical Regulations for Kazakhstan, Belarus and the Russian Federation which is an agreement signed by Russia, Belarus and Kazakhstan on October 18 2010, the Customs Union Committee shall devote to formulating uniform standard and requirement to ensure the safety of product. One certification is applicable for three countries, which forms the Russia-Belarus-Kazakhstan CU-TR certification with a uniform mark EAC. Regulation put into effect gradually from February 15^th 2013. In January 2015, Armenia and Kyrgyzstan joined Customs Union.

▍CU-TR Certificate Type and Validity

1. Single Shipment Certificate

Single shipment certificate is only applicable to specified batch, specified product stipulated in a contract. Specific information is strictly under control, such as item name, quantity, specification contract and Russian client. When applying for the certificate, no samples are requested to offer but documents and information are required.

1. Certificate with validity of one year

Once a product is granted the certificate, manufacturers can export products to Russia within 1 year without limit of shipment times and quantities.

1. Certificate with validity of three years

Once a product is granted the certificate, manufacturers can export products to Russia within 3 years without limit of shipment times and quantities.

1. Certificate with validity of five years

Once a product is granted the certificate, manufacturers can export products to Russia within 5 years without limit of shipment times and quantities.

b) Test
The test shall be carried out in an ambient
temperature of 20 °C ± 5 °C. Each test
battery shall be discharged at a constant
current of 0,2 It A, to a final discharge
voltage specified by the manufacturer.
Sample batteries shall then be charged at
a constant current of 2,0 It A, using a
supply voltage which is:
• 1,4 times the upper limit charging voltage
presented in Table A.1 (but not to exceed
6,0 V) for single cell/cell block batteries or
• 1,2 times the upper limit charging voltage
presented in Table A.1 per cell for series
connected multi-cell batteries, and
• sufficient to maintain a current of 2,0 It A
throughout the duration of the test or until
the supply voltage is reached.
• However, in case the charging voltage
specified by the manufacturer is higher
than the overcharge test voltage, the
maximum charging voltage specified
by manufacturer should be applied with
2.0 ItA,
(e.g., quick charging power bank, etc.)
