▍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 15th 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.
7.6 Crush
After charging the cell according to the test method specified in 4.5.1, place the cell in two
planes and crush it perpendicular to the direction of the electrode plate. A squeezing
force of 13.0 kN + 0.78 kN is applied between the two plates.
Once the pressure reaches the maximum value, the crush test can be stopped. During
the test, the cell cannot be short-circuited. When the cylindrical cell is squeezed, the
longitudinal axis is parallel to the two flat plates. The square cell and the flexible
package cell are only subjected to the extrusion test on the wide side of the cell.
The button cell is subjected to a squeeze test with the upper and lower sides of the cell
parallel to the two plates.
Refer to Figure 2 for cell placement in the
test.
One sample for each crush test.
The cell should not fire or explode

7.6 Crush
After the cell is fully charged in accordance
with the test method specified in 4.5.1, place
the cell in two planes and squeeze it
perpendicular to the direction of the electrode
plate. A squeezing force of 13.0 kN ± 0.78 kN
is applied between the two plates.
The pressing speed is not higher than 5
mm/s.
Once the pressure reaches the maximum
value or the voltage of the cell drops by
one-third, the flat compression test can be
stopped. The cell should be prevented from
external short-circuit during the test.
When the cylindrical battery is crushed, the
longitudinal axis is parallel to the two plates.
The crushed battery and soft-packaged cell
are only crushed on the wide side of the cell.
The button battery is squeezed with the upper
and lower sides of the battery parallel to the
two plates.
.
For flexible packaging cells, a
semi-cylinder with a diameter of 25 m
needs to be placed on the wide surface of
the cell and then squeezed. The
longitudinal axis of the semi-cylinder is
parallel to the wide surface of the cell, and
the length must be greater than the size of
the cell to be squeezed.
Refer to Figure 3 for cells placement in the
test.
One sample for each crush test.
The cell should not catch fire or explode.
