GOST‑K (ST‑RK) Certification for High‑Voltage Switch‑Gear & Distribution Panels (＞1 kV, Kazakhstan Market)

1. Governing‑Regulations & Core Principle

Responsible authority

KazStandard (Committee for Technical Regulation and Metrology of Kazakhstan).

Legal‑basis

Kazakhstan technical regulation for high‑voltage equipment under government Order №435‑НҚ, which mandates compulsory certification for HV‑equipment above 1000 VҚазақ....

Voltage dividing‑line rule:

LV switch‑cabinets ≤1000 V: only EAC‑DoC / EAC‑CoC under TR‑CU‑004‑2011 is valid, GOST‑K is unnecessary.

HV switch‑gear＞1 kV (6 kV‑10 kV‑35 kV‑110 kV KRU, KSO, complete‑set distribution cabinets): out‑of‑scope of TR‑CU‑004‑2011. EAC‑certificate is completely invalid for Kazakhstan customs‑clearance and national‑grid tender; GOST‑K (ST‑RK) certification is mandatory.

Important limitation: Russian GOST‑R PCT certificate cannot replace GOST‑K in Kazakhstan. Russian GOST‑R‑IEC‑62271‑1 test‑reports serve merely as reference documents; key‑items still require testing by Kazakhstan‑approved labs.

2. Mandatory Adopted Standards for HV Switch‑Cabinets

Main safety standard: ST‑RK‑IEC‑62271‑1‑2019 (equivalent to IEC‑62271‑1‑2017), together with GOST‑14695‑2014 for high‑voltage cubicles.

Climate‑test standard: GOST‑15150‑69 (XL‑50℃ low‑temperature test is compulsory for projects in northern Kazakhstan).

EMC‑standard for shielded switch‑gear: GOST‑CISPR‑11‑2015 covering radiated‑emission and immunity‑tests.

Fire‑safety requirement: GOST‑31565‑2012 for indoor substation‑type switch‑cabinets.

Additional grid‑project requirement: seismic‑vibration test complying with Kazakhstan local seismic‑standard for state‑grid projects.

If CT‑PT instrument transformers are installed inside switch‑cabinets, separate Kazakhstan state‑metering registration is required besides GOST‑K certificate.

3. Two GOST‑K Certification Schemes for HV Switch‑Gear

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

Validity: Valid only for one specific export contract with fixed quantity, invalid for subsequent shipments.

Requirements:

Document‑review mode, factory‑audit is waived completely;

Submit commercial documents (contract, pro‑forma invoice), Russian‑language technical‑dossier and available type‑test‑reports; partial‑test‑items may be exempted after assessment by certification‑body.

Best‑fit scenario: One‑off project‑based export for Kazakhstan clients.

Lead‑time: 4‑6 weeks, relatively lower‑cost.

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

For regular mass‑supply for Kazakhstan national‑grid and long‑term repeated export business.

Mandatory‑pre‑conditions:

Complete full‑set type‑tests for HV switch‑gear in Kazakhstan‑authorized labs (such as KAZTEST) complying with ST‑RK‑IEC‑62271‑1‑2019.

ISO9001‑2015 certificate is a prerequisite.

Factory‑audit rules:

1‑year certificate: one Kazakhstan‑qualified expert conducts on‑site factory‑audit in China.

3‑year certificate: two authorized experts perform factory‑audit; annual surveillance‑audit plus yearly random‑sample‑test are required throughout the whole validity period.

After approval: Electronic GOST‑K certificate with dynamic QR‑code is issued and registered on KazStandard official database; paper‑version certificates are no longer accepted from 2025 onwards.

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

4. Full Document‑List (All documents need Russian‑or‑Kazakh‑language notarized translation)

Manufacturer’s business license with notarized Russian translation.

Power‑of‑Attorney for Kazakhstan‑local authorized‑representative (AR is compulsory for Chinese manufacturers).

Valid ISO9001‑2015 certificate.

Russian‑language technical‑dossier for HV switch‑cabinet:

Technical‑passport (Технический паспорт);

General‑arrangement drawings, single‑line diagrams, bus‑bar calculation documents;

Component‑certificates (breakers, CT/PT, relays with their own EAC or GOST‑R reports);

Operation‑maintenance manual and Russian‑language name‑plate design.

Type‑test‑reports: IEC‑62271‑1, GOST‑15150‑69 (‑50℃), GOST‑CISPR‑11‑2015, fire‑safety and seismic‑test‑results.

Commercial documents (contract, packing list) are required only for single‑batch application.

5. Step‑by‑Step Certification‑Procedure

Appoint Kazakhstan‑Rosaccreditation‑approved certification‑body and local authorized‑representative inside Kazakhstan.

Submit full‑set notarized documents for preliminary‑review.

Deliver cabinet‑components or whole‑set samples to Kazakhstan‑recognized labs to finish required type‑tests.

Conduct on‑site factory‑audit if applying for 1‑year or 3‑year long‑term certificate.

Final document review, database registration and issue electronic GOST‑K certificate.

Mark the GOST‑K logo and QR‑code on switch‑cabinet shell and packing‑box as per Kazakhstan marking‑requirements.

‍6. Practical 2026 Export‑Suggestions

If you ship HV‑switch‑gear to Russia and Kazakhstan simultaneously: apply separate‑certificates: GOST‑R‑PCT for Russia and GOST‑K‑ST‑RK for Kazakhstan; they cannot be mutually‑recognized.

For one‑time project‑order: select single‑batch GOST‑K certificate to avoid factory‑audit and save your cost.

If you also supply high‑voltage products to Kyrgyzstan, Uzbekistan and Azerbaijan:

Kyrgyzstan＞1 kV switch‑gear: GOST‑KG‑CoC is required; GOST‑K is invalid there;

Uzbekistan＞1 kV switch‑gear: apply GOST‑UZ (Oʻz‑DSt); Russian‑GOST‑R reports are only reference‑files;

Azerbaijan: obtain AZS‑CoC certificate, EAC‑certificate is invalid for Azerbaijan market.

Carry‑out full‑set IEC‑62271‑1‑series tests in Russia‑approved labs first; Tajikistan and Azerbaijan can accept these reports and reduce repeated‑testing costs.
