High‑Voltage Cable GOST‑K (ST‑RK) Certification for Kazakhstan (Full‑English Version)

1. Fundamental Regulation & Jurisdiction

Governing‑Bodies and Legal‑Basis

Regulator: KazMemST (Committee for Technical Regulation and Metrology of Kazakhstan, KazStandard).

Mandatory law: Kazakhstan Government Resolution №435‑НҚ (Technical Regulation for high‑voltage equipment).

Critical dividing‑line rule:

Low‑voltage cables (AC ≤1000 V): only EAC‑DoC / EAC‑CoC (TR‑CU‑004‑2011) is valid for Kazakhstan, GOST‑K is not required.

High‑voltage cables＞1 kV (6‑10‑35‑110‑220 kV): out of coverage of TR‑CU‑004‑2011, EAC‑certificate is completely invalid in Kazakhstan. GOST‑K (ST‑RK) certification is legally compulsory for customs clearance and Kazakhstan national‑grid tender projects.

Important limitation: Russian GOST‑R PCT certificate is only accepted in Russia, it cannot replace GOST‑K for Kazakhstan customs‑clearance. Russian GOST‑IEC‑60502‑2 test‑reports can only be treated as reference documents; key‑items usually need retesting by Kazakhstan‑authorized labs.

2. Enforced Standards for HV‑Cables

Main performance standard: ST‑RK‑IEC‑60502‑2‑2019 (identical with IEC‑60502‑2‑2014 for 6‑35 kV extruded‑insulation cables).

Fire‑safety standard: GOST‑31565‑2012 (flame‑retardant, low‑smoke‑zero‑halogen LSZH requirement for grid‑projects).

Climate‑condition standard: GOST‑15150‑69 (XL‑50℃ low‑temperature test is mandatory for Siberia‑climate zones of Kazakhstan).

EMC standard: GOST‑CISPR‑11‑2015 for shielded high‑voltage cables.

3. Two Available GOST‑K Certification Schemes for HV‑Cables

Scheme‑1: Single‑batch Certificate (Партийный сертификат)

Valid scope: Only for one‑specific export contract, fixed quantity and consignment; invalid for future shipments.

Requirements:

Document‑review only; factory‑audit is NOT required;

Provide contract, pro‑forma invoice, packing list, Russian‑language technical‑dossier and existing type‑test‑reports; partial‑tests may be waived;

Suitable‑scenario: One‑time project‑based export to Kazakhstan.

Lead‑time: 4‑6 weeks, lower‑cost.

Scheme‑2: Serial‑production long‑term GOST‑K CoC‑Certificate (1‑year or 3‑year validity, high‑risk mode)

Applicable‑scenario: Mass‑production and repeated‑supply for Kazakhstan national‑grid, long‑term regular export.

Compulsory requirements:

Complete type‑testing for HV‑cables in Kazakhstan‑accredited laboratories following ST‑RK‑IEC‑60502‑2‑2019;

Factory‑audit is mandatory:

1‑year certificate: 1 Kazakhstan‑authorized expert conducts on‑site factory‑audit in China;

3‑year certificate: two‑experts perform factory‑audit, plus annual surveillance‑audit and yearly‑product‑sampling test throughout the validity period;

ISO9001‑2015 certificate is a prerequisite;

After‑approval: Electronic GOST‑K certificate with QR‑code is issued and registered in KazStandard official database; paper‑version certificate is not accepted after‑2025.

Lead‑time: 8‑12 weeks including sample‑testing and factory‑audit.

4. Mandatory Document Checklist (All files need Russian‑or‑Kazakh‑language notarized translation)

Manufacturer’s business license (Chinese + Russian notarized version).

Power‑of‑Attorney issued to Kazakhstan‑local authorized‑representative (mandatory for Chinese manufacturers).

Valid ISO9001‑2015 certificate.

Russian‑language technical‑dossier:

Technical‑passport (Технический паспорт);

Product drawing, structure‑description, raw‑material list;

Operation‑maintenance manual, nameplate design in Russian.

Type‑test‑reports: IEC‑60502‑2, GOST‑31565‑2012, GOST‑15150‑69‑XL‑50℃, EMC‑CISPR‑11‑2015 test‑results.

Contract and commercial‑documents (only required for single‑batch certificate).

5. Certification‑Execution Process

Select Kazakhstan‑Rosaccreditation‑approved certification‑body and appoint local‑AR (Authorized‑Representative inside Kazakhstan).

Submit full‑set notarized documents for preliminary‑review.

Sample‑testing: deliver cable‑samples to Kazakhstan‑recognized labs for required‑tests.

Factory‑audit: carry‑out on‑site audit if applying for 1‑year or 3‑year long‑term certificate.

Final review by certification‑body, register in KazStandard database and issue electronic GOST‑K certificate.

Marking: Affix GOST‑K logo and required Russian‑language technical‑data on cable outer‑sheath and packing box after‑certification approval.

6. Practical‑Suggestion for Your Export‑Business

If you deliver HV‑cables to Russia and Kazakhstan at the same time: apply for separate‑certificates: GOST‑R‑PCT for Russia and GOST‑K‑ST‑RK for Kazakhstan, these two‑certificates cannot be mutually‑recognized.

Project‑order: choose single‑batch GOST‑K certificate to skip factory‑audit and save your expense.

Long‑term bulk‑export: apply for a 3‑year GOST‑K CoC certificate; finish full‑set GOST‑IEC‑60502‑2 tests in Russia‑approved labs first, which can reduce retest‑items for Tajikistan and Azerbaijan later.

For Kyrgyzstan high‑voltage cables＞1 kV: you need GOST‑KG certificate separately, GOST‑K is not valid in Kyrgyzstan.
