▍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

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

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.

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.

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.

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.

▍Why MCM?

●MCM possesses a group pf professional engineers to study custom union latest certification regulations, and to provide close projects follow-up service, ensuring clients’ product enter into the region smoothly and successfully.

●The abundant resources accumulated through battery industry enables MCM to provide efficient and lower-cost service for client.

●MCM builds close cooperation with local relevant organizations, ensuring latest information of CU-TR certification is shared accurately and timely with clients.

Recently, many customers have inquired about the contents of the draft version of the newly
GB31241（not release yet）.The main differences between the current version 2014 and the draft
version are organized for your reference:
Clause GB31241 2014 GB31241 draft version
3.8
Rated energy -
Added the definition of “rated energy”
3.8 Rated energy
The energy value of the cell or battery
determined under the specified conditions
stated by the manufacturer’s trademark is
calculated by multiplying the nominal voltage
by the rated capacity, and can be rounded up,
in watt hours (Wh) or milliwatt hours (mWh).
Note: For the rated energy of the battery,
when the values calculated by the cell and
battery parameters are different, take the
larger one.
3.9 Nominal
voltage -
Added the definition of “Nominal voltage”
3.9 Nominal voltage
Used to identify the appropriate approximate
value of the cell or battery voltage.
3.10
Reference
test current
-
Added the definition of “Reference test
current”
3.10 Reference test current
The reference test current is expressed by It,
and its value is the same as the rated
capacity (C).
Note: The unit is ampere (A) or milliampere
(mA).
3.11
Upper limited
charging
voltage
3.9 Upper limited charging voltage Uup
The highest safe charging voltage that the
cell or battery can withstand as specified by
the manufacturer.
Note: For example, the upper charging
voltage of a single-cell lithium cobalt
oxide/graphite battery is generally 4.25 V.
Replaced with below note
3.11 Upper limited charging voltage Uup
The highest safe charging voltage that the cell
or battery can withstand as specified by the
manufacturer. 。
Note: Refer to Appendix A for definitions
