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

Governing‑Body: KAZMEMST (Committee for Technical Regulation and Metrology of Kazakhstan), legal basis: Kazakhstan Government Resolution №435‑НҚ.

There are two distinct pathways: Single‑Batch Certificate and Serial‑Production Long‑Term Certificate (1‑year / 3‑year).

Pre‑Stage: Confirm Certification Scheme and Appoint Local Authorized‑Representative (AR)

Confirm product scope: HV switch‑cabinet＞1kV (6‑35‑110kV KRU, KSO) is out‑of‑scope of TR‑CU‑004‑2011; EAC‑certificate is invalid; GOST‑K is mandatory for customs‑clearance and grid‑tender.

Confirm applicable standards:

Main standard: ST‑RK‑IEC‑62271‑1‑2019; GOST‑14695‑2014

Climate‑test: GOST‑15150‑69 (‑50℃ XL version for Northern‑Kazakhstan)

EMC‑standard: GOST‑CISPR‑11‑2015; fire‑safety GOST‑31565‑2012

Choose certification mode:

Option‑1: Single‑batch certificate (only for one export contract, no factory‑audit). Suitable for one‑off project‑order.

Option‑2: Serial‑production certificate (1‑year or 3‑year valid for repeated shipments; factory‑audit compulsory). For long‑term supply for Kazakhstan National‑Grid.

Appoint Kazakhstan‑registered local Authorized‑Representative: Chinese manufacturers cannot apply directly. The local AR signs application documents, submits files to certification‑body and KazStandard official registry. Select a KAZMEMST‑accredited certification‑body approved by Rosaccreditation‑Kazakhstan.

Stage‑1: Prepare Full Document Package (All files require Russian‑language notarized translation)

Mandatory documents checklist:

Manufacturer’s business license with notarized Russian‑translation;

Power‑of‑Attorney issued to Kazakhstan‑local authorized‑representative;

ISO9001‑2015 certificate (compulsory for long‑term GOST‑K‑CoC);

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

Technical‑passport (Технический паспорт);

General‑arrangement drawings, single‑line diagram, bus‑bar‑calculation reports;

Component‑certificates for breakers, CT/PT, relays; if CT‑PT is fitted inside cabinets, separate Kazakhstan‑state‑metering‑registration shall be arranged afterwards;

Russian‑version operation‑maintenance manual and name‑plate drawing;

Existing type‑test‑reports: IEC‑62271‑1, Russian‑GOST‑R‑IEC‑62271‑1‑test‑reports can serve as reference‑documents, but key‑items usually require re‑testing in Kazakhstan‑authorized labs;

Commercial documents (contract, pro‑forma‑invoice, packing‑list): required only for single‑batch application.

After finishing document sorting, the local AR submits whole‑set files to certification‑body for document‑review. If documents are incomplete, revise and resubmit.

Stage‑2: Sample Testing in Kazakhstan‑Approved Laboratories

Deliver whole‑set switch‑cabinet samples or core‑components to KAZTEST or other KAZMEMST‑authorized labs in Kazakhstan.

Carry‑out full‑set type‑tests according to ST‑RK‑IEC‑62271‑1‑2019:

Power‑frequency withstand‑voltage test, short‑circuit withstand‑test, temperature‑rise test, IP‑protection‑verification;

Low‑temperature test GOST‑15150‑69 (‑50℃); EMC‑CISPR‑11‑2015 test; fire‑safety‑test GOST‑31565‑2012; seismic‑test for national‑grid‑projects;
