BESS Fire Safety Installation — Cambodia Building and Fire Authority Requirements (Ministry of Interior / Fire Marshal) China manages BESS fire safety under a combination of mandatory standards and project-level fire-safety review. GB 44240-2024 includes fire-safety provisions for BESS cells and modules. GB/T 36276-2023 and GB/T 36558-2023 cover system-level safety including fire-related requirements. Project-level fire-safety review in China is governed by local fire authority approval procedures. These Chinese fire-safety standards and domestic approval procedures are not recognised by Cambodian fire or building authorities as equivalent to IEC 62933-5-2 or NFPA 855-based fire-safety installation requirements. BESS fire-safety evidence prepared under Chinese standards must be supplemented with IEC 62933-5-2 or NFPA 855-aligned design documentation for Cambodian authority and project-owner review.GB 44240-2024 — 电化学储能系统用二次锂电池安全要求 (includes fire-safety provisions for BESS cells/modules; mandatory, effective August 1, 2025)
GB/T 36558-2023 — 电力系统电化学储能系统通用技术条件 (General Technical Requirements for Electrochemical Energy Storage Systems in Power Systems)		 Cambodia does not have a specific standalone national fire code for stationary battery energy storage systems (BESS) as of the dataset date. Fire safety for commercial and industrial buildings — including BESS installations — falls under the jurisdiction of the Ministry of Interior's General Department of National Police (fire marshal function) and relevant municipal or provincial building authorities. In the absence of a BESS-specific fire code, project developers and installers in Cambodia typically reference IEC 62933-5-2 (Safety Requirements for grid-integrated electrochemical-based energy storage systems) and apply local building fire regulations and fire authority approval requirements. International project financiers and EPC contractors operating in Cambodia commonly apply international best-practice standards, including NFPA 855 (Standard for the Installation of Stationary Energy Storage Systems) or IEC 62933-5-2, as the technical design basis for BESS fire safety. Formal adoption of NFPA 855 or any equivalent BESS-specific fire installation standard by a Cambodian authority has not been confirmed from official sources as of the dataset date — direct verification with the relevant local fire authority and building authority is required before project design is finalised.IEC 62933-5-2 — Electrical Energy Storage Systems — Safety Requirements — Electrochemical-based systems for grid integration (IEC-based reference framework; ISC adoption status to be confirmed directly with ISC at isc.gov.kh)
IEC 62933-5-1:2024 — Electrical Energy Storage Systems — Safety considerations — Hazard identification, risk assessment and risk mitigation (system-level safety standard expected in project specifications)
NFPA 855 — Standard for the Installation of Stationary Energy Storage Systems (international best-practice reference widely applied by project financiers and EPCs in Cambodia; formal adoption by Cambodian authority unconfirmed as of dataset date)
Ministry of Interior, Cambodia (General Department of National Police — fire marshal function) — building and fire safety authority for commercial and industrial facilities		 Gap: No confirmed BESS-specific fire installation code exists in Cambodia as of the dataset date. Chinese BESS fire-safety documentation based on GB standards does not satisfy the IEC 62933-5-2 and local building fire regulation requirements that project owners, international financiers, and Cambodian building authorities will apply. Exporters and project teams should: (a) verify directly with the relevant Cambodian municipal or provincial building authority and fire marshal the applicable building and fire codes for the specific project location and installation type before design is finalised; (b) prepare BESS fire-safety design documentation aligned with IEC 62933-5-2 — including thermal-runaway propagation mitigation, gas detection or ventilation design, suppression system design, emergency shutdown procedures, and separation distances; (c) where international project financiers apply NFPA 855 as the design basis, prepare supplementary NFPA 855-aligned documentation; (d) engage a fire protection engineer experienced in IEC 62933-5-2 or NFPA 855 BESS installations for design review before application submission.[INFORMATIONAL] No confirmed BESS-specific fire installation code exists in Cambodia as of the dataset date. Chinese GB-standard fire-safety documentation does not satisfy the IEC 62933-5-2 and local building fire regulation requirements applied by project owners, international financiers, and Cambodian building and fire authorities. Engage the relevant Cambodian building and fire authority and a fire protection engineer experienced in IEC 62933-5-2 at the earliest project stage to confirm applicable fire code requirements and design requirements before committing to system layout or equipment specification.

EAC and EDC Grid Connection for BESS — 50 Hz System, IEC 62933, and EAC Licensing Requirements China's grid-connection requirements for BESS are governed by GB/T 36558-2023 (General Technical Requirements for Electrochemical Energy Storage Systems in Power Systems) and GB/T 34120-2023 (Technical Specification for Electrochemical Energy Storage System Connected to Distribution Network). The PCS (energy storage converter) is assessed under NB/T 42090-2016 (Technical Code for Testing of Energy Storage Converters). Chinese BESS products are validated by grid operators through National Energy Administration (NEA)-authorised procedures. China's grid operates at 50 Hz, 220/380 V (220 V single-phase, 380 V three-phase) — different from Cambodia's 230/400 V. PCS firmware and protection parameters configured for China's 220/380 V grid must be re-parameterised for Cambodia's 230/400 V, 50 Hz grid conditions before grid-connection testing and commissioning. Chinese GB/T standards and CQC/CCC marks are not recognised by EAC or EDC as equivalent to IEC 62933 evidence.GB/T 36558-2023 — 电力系统电化学储能系统通用技术条件 (General Technical Requirements for Electrochemical Energy Storage Systems in Power Systems)
GB/T 34120-2023 — 电化学储能系统接入配电网技术规范 (Technical Specification for Electrochemical Energy Storage System Connected to Distribution Network)
NB/T 42090-2016 — 储能变流器检测技术规程 (Technical Code for Testing of Energy Storage Converters)		 The Electricity Authority of Cambodia (EAC) — operating under the Law on Electricity (2001) — is the electricity regulator and licensor in Cambodia. EAC issues licences for the generation, transmission, distribution, import/export, and sale of electricity, and its licensing scope covers grid-connected energy storage assets. All grid-connected BESS installations — whether utility-scale or behind-the-meter — require formal EAC licensing and grid-connection approval before commissioning. EDC (Electricité du Cambodge), Cambodia's main national utility, owns and operates the transmission and distribution network in most of Cambodia; behind-the-meter and grid-scale BESS systems interconnecting with the EDC network require EDC grid-connection technical approval in addition to EAC licensing. Cambodia's grid operates at 230 V single-phase / 400 V three-phase, 50 Hz. BESS power conversion systems (PCS) must be designed, configured, and validated for Cambodia's 230/400 V, 50 Hz grid. IEC 62933 (Electrical Energy Storage Systems) series, including IEC 62933-5-2 (Safety Requirements for grid-integrated electrochemical-based systems), is the IEC-based reference framework expected in project and EAC/EDC technical specifications. A publicly accessible EAC or EDC technical specification document specifically for BESS grid connection has not been confirmed as of the dataset date; project-specific connection agreement terms and licence conditions must be obtained directly from EAC (eac.gov.kh) and EDC (edc.com.kh).Law on Electricity (2001, Cambodia) — establishes EAC as the electricity regulator and licensor

IEC 62477-1 — Safety Requirements for Power Electronic Converter Systems and Equipment (applicable to BESS PCS)		 Gap: Chinese GB/T BESS grid-connection certificates and NEA approvals do not satisfy EAC licensing or EDC grid-connection requirements in Cambodia. Key issues requiring attention: (a) EAC licence — obtain EAC energy storage licence before installation; the licence category and conditions for grid-connected BESS are project-specific and must be confirmed directly with EAC (eac.gov.kh); (b) EDC technical approval — engage EDC (edc.com.kh) at the earliest project stage to obtain grid-connection technical requirements before equipment procurement is finalised; (c) grid voltage — Cambodia is 230/400 V whereas China is 220/380 V; PCS voltage protection thresholds and ride-through settings must be reconfigured and retested for Cambodia's grid parameters; (d) IEC 62933 series compliance — prepare IEC 62933-2-1 and IEC 62933-5-2 test and design documentation as expected by project specifications and EAC/EDC technical review, as Chinese GB/T standards are not accepted as equivalent; (e) communication protocols — confirm the SCADA / communication interface protocol required by EDC for BESS monitoring before equipment specification is finalised.[INFORMATIONAL] Chinese GB/T BESS grid-connection compliance and NEA approvals do not satisfy EAC licensing or EDC grid-connection requirements in Cambodia. BESS PCS must be re-parameterised for Cambodia's 230/400 V at 50 Hz grid. Engage EAC and EDC at the earliest project stage to determine licence requirements, connection agreement technical conditions, applicable IEC 62933 evidence, and SCADA/communication protocol specifications. No publicly accessible EAC or EDC technical specification specifically for BESS grid connection has been confirmed as of the dataset date — direct engagement with EAC (eac.gov.kh) and EDC (edc.com.kh) is essential before equipment procurement is finalised.

Cell and Module Safety — IEC 62619 and IEC 62933 as International Baseline for Cambodia BESS Project Acceptance China's primary mandatory standard for BESS cells from August 2025 is GB 44240-2024 (Secondary Lithium Cells and Batteries Used in Electrical Energy Storage Systems — Safety Requirements), which replaces the prior GB/T 36276 series as the mandatory safety baseline for large-format BESS batteries. The prior voluntary standard GB/T 36276-2023 (Lithium-Ion Batteries for Electrical Energy Storage) provides the technical framework for cells, modules, and battery clusters used in EES. Chinese CQC and CCC marks are domestic Chinese certification marks and are not recognised by ISC or EAC as equivalent to IEC 62619 conformity. Exporters must obtain IEC 62619 test evidence from an ILAC-accredited laboratory in addition to any Chinese GB compliance, as Chinese standards are not accepted as substitutes in Cambodia project specifications or EAC/EDC technical requirements.GB 44240-2024 — 电化学储能系统用二次锂电池安全要求 (Secondary Lithium Cells and Batteries Used in Electrical Energy Storage Systems — Safety Requirements; mandatory, effective August 1, 2025)
GB/T 36276-2023 — 电力储能用锂离子电池 (Lithium-Ion Batteries for Electrical Energy Storage; voluntary, effective July 1, 2024)		 Cambodia's Institute of Standards of Cambodia (ISC) — the national standards body — adopts IEC standards as the basis for Cambodian standards (CS series). ISC does not operate a pre-market product certification mandatory scheme for BESS equivalent to CE marking or SABER as of the dataset date. However, IEC 62619 (Safety Requirements for Secondary Lithium Cells and Batteries for Use in Industrial Applications) is the internationally expected safety standard for lithium BESS cells and modules, and the Electricity Authority of Cambodia (EAC) and EDC, project owners, and international financiers operating in Cambodia are expected to reference IEC 62619 compliance as a technical prerequisite for BESS procurement and installation approval. IEC 62133 (Safety Requirements for Portable Sealed Secondary Lithium Cells and Batteries) may apply to portable battery components. IEC 62619 conformity evidence from an ILAC-accredited laboratory is the expected market-entry baseline for Cambodia BESS projects. Chinese CQC/CCC marks are not recognised by ISC or EAC as equivalent to IEC 62619 conformity.IEC 62619:2022 — Safety Requirements for Secondary Lithium Cells and Batteries for Use in Industrial Applications (internationally expected baseline for BESS cell/module safety in Cambodia project specifications)

ISC (Institute of Standards of Cambodia) — national standards body, adopts IEC standards; isc.gov.kh
EAC (Electricity Authority of Cambodia) — electricity regulator and licensor; expected to apply IEC-based technical prerequisites for BESS projects; eac.gov.kh		 Critical gap: Cambodia project owners, EAC, and international financiers operating in Cambodia reference IEC 62619 as the expected safety evidence for BESS cells and modules. Chinese GB 44240-2024 and GB/T 36276-2023 are not harmonised with IEC 62619 and are not accepted as substitutes in Cambodia project technical specifications. Chinese CQC/CCC marks carry no recognition under ISC or EAC frameworks. Exporters should: (a) obtain IEC 62619 type-test certificates from an ILAC-accredited laboratory for cells and modules supplied to Cambodia BESS projects; (b) confirm the applicable IEC 62619 edition referenced in the project specification or EAC/EDC technical requirements before committing to a test programme; (c) verify with ISC (isc.gov.kh) whether any Cambodian Standard (CS) specifically for BESS cells or systems has been adopted that may impose additional conformity obligations; (d) note that Cambodia is an emerging BESS market and regulatory requirements may evolve — direct verification with ISC and EAC before each project is strongly recommended.[INFORMATIONAL] No confirmed standalone mandatory BESS product safety regulation has been identified for Cambodia as of the dataset date; however, IEC 62619 is the internationally expected technical baseline for BESS cell and module safety in Cambodia project specifications and EAC/EDC technical requirements. Chinese GB 44240-2024 and GB/T 36276-2023 certification alone is not sufficient for Cambodia project acceptance. Chinese CQC/CCC marks carry no recognition under ISC or EAC frameworks. Verify ISC current CS standards scope, confirm IEC 62619 evidence requirements with the project owner and EAC/EDC, and obtain type-test certificates from an ILAC-accredited laboratory before shipment.

UN 38.3 Transport Safety Testing — Mandatory for Lithium Battery Imports to Cambodia via Preah Sihanouk Port and Land Routes Chinese BESS cell and module manufacturers are required to comply with UN 38.3 for export shipments under international transport conventions. Chinese manufacturers typically hold UN 38.3 test reports and test summaries from CNAS-accredited testing laboratories such as UL, SGS, Bureau Veritas, TÜV, or CAICT. The UN 38.3 Test Summary (required since January 1, 2020) must cover the specific cell or battery type being shipped. A Chinese-origin UN 38.3 test summary from an accredited laboratory is acceptable for Cambodia imports — the key gap is ensuring the test summary covers the specific cell model, chemistry, capacity, and configuration of the BESS units being shipped, and that it is maintained current with any cell design changes. For land-route shipments via Thailand or Vietnam, verify that packaging, marking, and documentation comply with the dangerous goods regulations of all transit countries.UN 38.3 test reports and test summaries from CNAS-accredited Chinese laboratories (CAICT, UL China, SGS China, Bureau Veritas China, TÜV Rheinland China) — acceptable for international transport if the test summary covers the specific cell/battery type being shipped UN 38.3 (Recommendations on the Transport of Dangerous Goods — Manual of Tests and Criteria, Part III, Section 38.3) specifies eight mandatory transport safety tests (T1 Altitude Simulation, T2 Thermal Test, T3 Vibration, T4 Shock, T5 External Short Circuit, T6 Impact/Crush, T7 Overcharge, T8 Forced Discharge) for lithium metal and lithium-ion cells and batteries of all sizes, including cells, modules, and battery packs used in stationary BESS. Since January 1, 2020, a UN 38.3 Test Summary is mandatory documentation that must accompany lithium battery shipments under international transport regulations (IATA DGR, IMDG Code, ADR). Cambodia is party to international transport conventions and this requirement applies to all lithium battery imports by air, sea, or road — there is no Cambodia-specific exemption. The primary port of entry for BESS equipment imported to Cambodia is Preah Sihanouk Port (Sihanoukville), also known as Sihanoukville Autonomous Port (PAS); land routes via Thailand or Vietnam are also used. BESS cells and modules exported from China to Cambodia must be covered by a valid UN 38.3 Test Summary from an accredited laboratory before shipment regardless of the transport route.UN 38.3 — Recommendations on the Transport of Dangerous Goods, Manual of Tests and Criteria, Part III, Section 38.3 (mandatory transport safety tests T1–T8 for all lithium cells and batteries)
IATA Dangerous Goods Regulations (DGR) — applies to all air freight of lithium batteries including BESS cells and modules
IMDG Code — applies to all sea freight of lithium batteries including BESS cells and modules shipped via Preah Sihanouk Port (Sihanoukville Autonomous Port)
ADR — European Agreement concerning the International Carriage of Dangerous Goods by Road (applies to land-route shipments via Thailand or Vietnam where ADR-equivalent national regulations apply)
UN Model Regulations, 7th revised edition (2021) — Test Summary requirement in force since January 1, 2020		 The gap is documentation scope and currency, not standard equivalence. UN 38.3 is a universal requirement and Chinese-origin test summaries from accredited laboratories are accepted for Cambodia-bound shipments. Exporters should verify: (a) the UN 38.3 test summary covers the specific cell model (including chemistry, capacity, and format) being exported — a summary for a different cell model or capacity is not transferable; (b) the test summary is from a currently accredited laboratory; (c) any cell design change (electrolyte, separator, electrode, BMS firmware affecting charge/discharge) since the original UN 38.3 testing triggers a reassessment requirement; (d) module-level and battery-pack-level assemblies may require separate UN 38.3 assessment if they constitute a battery as defined under international transport regulations; (e) for sea freight via Preah Sihanouk Port (Sihanoukville Autonomous Port), engage a dangerous-goods shipping agent familiar with Cambodian customs and IMDG documentation requirements; (f) for land-route shipments via Thailand or Vietnam, verify DG transit requirements for all transit countries and confirm that packaging and documentation comply throughout the transit.[INFORMATIONAL] UN 38.3 transport compliance is universal — a Chinese-origin test summary from an accredited laboratory is accepted for Cambodia shipments provided it covers the specific cell model and is current. The primary risk is scope mismatch (wrong cell model or capacity in the summary) or an outdated summary after a cell design change. Verify test summary coverage and currency before each shipment. For sea freight, engage a dangerous-goods shipping agent familiar with Preah Sihanouk Port (Sihanoukville Autonomous Port) IMDG documentation requirements. For land-route shipments via Thailand or Vietnam, confirm DG transit requirements for all transit countries.
