| Fire Safety & Thermal Runaway Propagation — BESS (Romania / EU) | GB/T 36276-2023 (revised, released 6 August 2023 by SAC/SAMR, in force from 1 March 2024, superseding GB/T 36276-2018) covers lithium-ion battery packs and systems for stationary energy storage, including thermal-runaway tests at cell and module level. The 2023 revision tightened test conditions (e.g. external short-circuit resistance reduced from 5 mΩ to 1 mΩ) and expanded abuse-test coverage. However, the propagation-prevention test methodology and pass/fail thresholds differ from IEC 62933-5-2. GB/T 36276 does not adopt UL 9540A protocols, and system-level fire-compartment propagation data generated under Chinese test conditions is generally not in the format required by EU installers or Romanian authorities.GB/T 36276-2023 — Lithium-ion battery packs and systems for electric energy storage (released 6 August 2023, in force 1 March 2024, supersedes GB/T 36276-2018) GB/T 51048-2025 — Standard for Design of Electrochemical Energy Storage Power Station (issued 31 December 2025, effective 1 April 2026) |
IEC 62933-5-2:2020 sets safety requirements for grid-connected energy storage systems, including evaluation of thermal runaway propagation at cell, module and system level. EN IEC 62933-5-2 is the harmonised European adoption (harmonised status under OJ review as of 2026-06-11 due to Malamud ruling). Installations in Romania must demonstrate that thermal runaway in one cell does not propagate uncontrolled to adjacent cells/modules. Romanian fire-safety regulations (Normativ P 118 series) and installers additionally require UL 9540A fire-test data to quantify heat release and propagation risk for fire-compartment design. ASRO adopts EN standards as SR EN equivalents.IEC 62933-5-2:2020 — Electrical energy storage (EES) systems – Part 5-2: Safety requirements for grid-integrated EES systems EN IEC 62933-5-2 (harmonised EU adoption — harmonised status under review as of 2026-06-11 due to Malamud ruling) ANSI/CAN/UL 9540A:2025 (5th Edition, March 2025) — Test Method for Evaluating Thermal Runaway Fire Propagation in Battery Energy Storage Systems Normativ P 118/99 and P 118-2:2013 — Romanian fire safety design norms for buildings (administered by IGSU) |
Key gap: Chinese test reports under GB/T 36276 typically do not include the system-level thermal-runaway propagation test data required by IEC 62933-5-2 Annex C, nor UL 9540A heat-release-rate (HRR) and fire-spread data needed for Romanian building and fire-compartment approvals. ANRE project permits and Romanian fire-safety authority (IGSU) approvals increasingly require UL 9540A-format data. Chinese manufacturers rarely commission UL 9540A tests. This documentation gap is a frequent barrier at the EU project-finance and Romanian permitting stage.[INFORMATIONAL] INFORMATIONAL ONLY — Chinese BESS products certified to GB/T 36276 alone are likely to face documentation gaps when seeking Romanian/EU project permits or financing, specifically the absence of IEC 62933-5-2 system-level thermal-runaway propagation test data and UL 9540A fire-spread data. Manufacturers targeting Romania should commission supplementary testing to these standards. This is not legal advice; verify current requirements with a qualified EU notified body and Romanian fire-safety authority. | Romanian Standards Association (ASRO)2026-06-15 · reference |
| Grid Connection Requirements for BESS Power Conversion System (PCS / Storage Inverter) — Romania | GB/T 34120-2023 (Electrochemical energy storage system for connecting to the grid — Part 1: General specification; replacing GB/T 34120-2017) sets Chinese grid-connection requirements for electrochemical BESS. It is a recommended (推荐性) national standard, but compliance is effectively required by State Grid and Southern Grid connection rules. The Chinese standard is aligned to China's 220/380 V 50 Hz grid and does not address Romania's nominal 230/400 V conditions, ANRE/Transelectrica grid-code reactive-power curves, or Romanian anti-islanding thresholds.GB/T 34120-2023 — Electrochemical energy storage system for connecting to the grid (recommended national standard, supersedes GB/T 34120-2017) | BESS storage inverters (PCS) connecting to the Romanian grid must comply with EN 50549-1 (low voltage, ≤16 A/phase) or EN 50549-2 (medium voltage), as adopted by ASRO as SR EN 50549-1/-2. At the EU level, Commission Regulation (EU) 2016/631 (Requirements for Generators, RfG) sets binding requirements for power-generating modules above thresholds set by ANRE, covering fault ride-through, frequency response, and reactive power exchange. ANRE Order No. 30/2013 (Codul tehnic al rețelei electrice de distribuție, CRED) and the Transelectrica grid code (Codul tehnic al rețelei electrice de transport, CTET) specify national interconnection requirements. The Romanian grid operates at 230/400 V 50 Hz; nominal voltage differs from China's 220/380 V. Romanian-language technical documentation is expected by Transelectrica and distribution network operators (DNOs).EN 50549-1:2019 / SR EN 50549-1 (ASRO adoption) EN 50549-2:2019 / SR EN 50549-2 (ASRO adoption) Commission Regulation (EU) 2016/631 — Requirements for Generators (RfG) ANRE Order No. 30/2013 — Codul tehnic al rețelei electrice de distribuție (CRED) Transelectrica — Codul tehnic al rețelei electrice de transport (CTET) |
Key gap: Chinese PCS certified only to GB/T 34120 do not demonstrate compliance with EN 50549-1/-2, EU RfG 2016/631, ANRE CRED, or Transelectrica CTET. Voltage nominal difference (220/380 V China vs 230/400 V Romania) requires re-parameterisation and re-testing. Reactive-power curves, anti-islanding settings, and frequency-response thresholds per Romanian/EU grid codes are not validated by GB/T 34120 test reports. Romanian-language grid-connection application documentation required by Transelectrica/DNOs is not provided by default by Chinese manufacturers.[INFORMATIONAL] Chinese PCS / storage inverters certified only to GB/T 34120 are NOT compliant for Romanian/EU grid connection. Full re-testing to EN 50549-1 or EN 50549-2, EU RfG 2016/631, ANRE CRED, and Transelectrica CTET is required before connecting to the Romanian grid. Voltage nominal re-parameterisation is also required. | National Energy Regulatory Authority (ANRE), Romania2026-06-15 · reference |
| Cell & Battery Pack Safety — Romania / EU (EN IEC 62619) | GB/T 36276-2023 (lithium-ion battery packs and systems for stationary energy storage) and GB 31241-2022 (safety requirements for lithium-ion cells and batteries for portable electronic products) address cell and pack safety in China. GB 31241 is a mandatory (强制性) standard but scoped to portable electronics; GB/T 36276 is the primary recommended standard for stationary BESS. Neither is a recognised equivalent to EN IEC 62619 for EU CE marking purposes.GB/T 36276-2023 — Lithium-ion battery packs and systems for electric energy storage GB 31241-2022 — Safety requirements for portable lithium-ion cells and batteries (mandatory, but scoped to portable electronics) |
EN IEC 62619:2022 (Safety requirements for secondary lithium cells and batteries for use in industrial applications) is the harmonised EU standard for BESS cell and pack safety under the Low Voltage Directive (LVD 2014/35/EU). ASRO adopts it as SR EN IEC 62619. CE marking under LVD requires a Declaration of Conformity referencing EN IEC 62619 (or equivalent harmonised standard) and, for higher-risk products, a notified-body technical file. Romania applies EU harmonised standards through ASRO adoption.EN IEC 62619:2022 — Safety requirements for secondary lithium cells and batteries for use in industrial applications (harmonised under LVD 2014/35/EU) SR EN IEC 62619 (ASRO adoption) LVD 2014/35/EU — Low Voltage Directive |
Chinese BESS products holding only GB/T 36276 and GB 31241 test reports cannot use these to obtain EU CE marking under LVD or satisfy Romanian market surveillance requirements. EN IEC 62619 conformity testing by an accredited EU laboratory (or under a notified-body scheme) is required. Chinese test certificates from CNAS-accredited labs may be partially usable as supporting evidence, but EU Declaration of Conformity and technical file must reference EN IEC 62619 directly.[INFORMATIONAL] Chinese BESS products must obtain EN IEC 62619 conformity and EU CE marking under LVD 2014/35/EU to legally place the product on the Romanian market. GB/T 36276 and GB 31241 test reports alone are insufficient. Engage an EU accredited test laboratory or notified body. | Romanian Standards Association (ASRO)2026-06-15 · reference |
| ESS System-Level Safety & Battery Regulation Due Diligence — Romania / EU | China does not have an equivalent to EU Battery Regulation 2023/1542 lifecycle and due-diligence requirements. GB/T 36276-2023 covers system-level safety for stationary BESS but does not address carbon-footprint declaration, digital battery passport, or supply-chain due diligence. China's Extended Producer Responsibility (EPR) framework for batteries is less comprehensive than EU 2023/1542.GB/T 36276-2023 — Lithium-ion battery packs and systems for electric energy storage China EPR battery take-back regulations (various, administered by MEE) |
At system level, IEC 62933-5-2:2020 (EN adoption as SR EN IEC 62933-5-2 in Romania) covers grid-integrated EES system safety. Additionally, EU Battery Regulation 2023/1542/EU (effective 17 August 2023, replacing Directive 2006/66/EC) imposes lifecycle, due-diligence, carbon-footprint declaration, and digital battery passport requirements on batteries placed on the EU market, including stationary BESS. Key timelines: carbon footprint declaration rules apply from 18 August 2024 for EV batteries; extended to industrial batteries on a phased schedule. Romanian customs and market surveillance follow EU Battery Regulation enforcement.IEC 62933-5-2:2020 — Safety requirements for grid-integrated EES systems SR EN IEC 62933-5-2 (ASRO adoption) Regulation (EU) 2023/1542 — EU Battery Regulation (in force 17 August 2023) |
Chinese BESS exporters to Romania must comply with EU Battery Regulation 2023/1542 lifecycle, carbon-footprint declaration (phased timelines), and digital battery passport requirements — none of which are addressed by Chinese national standards. Supply-chain due-diligence documentation (cobalt, lithium, natural graphite sourcing) required by EU 2023/1542 is not routinely prepared by Chinese manufacturers for domestic sales.[INFORMATIONAL] EU Battery Regulation 2023/1542 applies to all BESS sold in Romania. Chinese exporters must prepare carbon-footprint declarations, supply-chain due-diligence reports, and (when mandated) digital battery passports. GB/T 36276 compliance alone is insufficient. Engage legal and technical counsel familiar with EU Battery Regulation implementation timelines. | EUR-Lex / European Parliament and Council2026-06-15 · reference |
| LVD Electrical Safety & CE Marking — Romania / EU | China's CCC (China Compulsory Certification) scheme, administered by CNCA, is the closest equivalent to EU CE marking for electrical safety. CCC certification for BESS is required under GB 4943.1 (IT equipment safety) or product-specific GB standards. CCC is not recognised in the EU; a CE marking obtained under EU LVD cannot be substituted by CCC, and vice versa.CCC (China Compulsory Certification) — administered by CNCA GB 4943.1:2022 — Safety of audio/video, information and communication technology equipment (mandatory) |
The EU Low Voltage Directive (LVD 2014/35/EU) requires all electrical equipment with operating voltage 50–1000 V AC or 75–1500 V DC placed on the EU market (including Romania) to carry CE marking, be accompanied by a Declaration of Conformity, and comply with applicable harmonised standards. For BESS, relevant harmonised standards include EN IEC 62619 (cell/pack safety), EN IEC 62933-5-2 (system safety), and IEC 62477-1 (power electronic converters). Romanian market surveillance authority (ANPC) enforces LVD compliance. ASRO publishes SR EN adoptions of harmonised standards.LVD 2014/35/EU — Low Voltage Directive EN IEC 62619:2022 (harmonised under LVD) EN IEC 62933-5-2 (harmonised status under OJ review as of 2026-06-11) IEC 62477-1:2022 — Safety requirements for power electronic converter systems and equipment SR EN adoptions (ASRO) of all above |
CCC certification and GB-standard test reports do not satisfy EU LVD CE marking requirements for Romania. A complete EU technical file, Declaration of Conformity referencing EU harmonised standards, and (where required) notified-body involvement must be prepared. Chinese factories typically lack EU-format DoC templates and harmonised-standard test reports for BESS.[INFORMATIONAL] CE marking under LVD 2014/35/EU is mandatory for BESS sold in Romania. CCC certification and Chinese GB test reports do not satisfy this requirement. Manufacturers must engage EU accredited laboratories, prepare EU-format technical files and Declarations of Conformity, and involve a notified body where required. | EUR-Lex / European Parliament and Council2026-06-15 · reference |
| Dangerous Goods Transport Classification & UN 38.3 Testing — BESS (Romania) | China's domestic dangerous-goods transport regulations for lithium batteries include GB/T 28014-2011 (lithium battery air transport) and JT/T 617 series (road transport). Chinese export consignments must also pass UN 38.3 testing, which is required globally. However, Chinese manufacturers' UN 38.3 test reports must comply with the most current edition (8th edition, 2023) including the Test Summary document format required by IATA/IMDG. Older test reports may not satisfy current Constanta port or Romanian customs requirements.GB/T 28014-2011 — Lithium batteries for air transport JT/T 617.7-2018 — Road transport of dangerous goods (lithium batteries) UN 38.3 (8th edition, 2023) — also required for China domestic export DG compliance |
Lithium batteries in BESS shipped to Romania are classified as Class 9 dangerous goods (UN 3480 — lithium ion batteries; UN 3481 — lithium ion batteries contained in or packed with equipment) under the UN Model Regulations. Romania applies ADR (road), RID (rail), IMDG (sea via Constanta port), and IATA (air) frameworks. All lithium batteries must pass UN 38.3 testing (UN Manual of Tests and Criteria, Part III, Section 38.3) before transport. A UN 38.3 Test Summary (per IATA 2024 DGR PI 965/967/968 and IMDG Code Amendment 41-22) must accompany each consignment. Constanta is Romania's main port for Black Sea and global freight.UN Model Regulations on the Transport of Dangerous Goods (23rd revised edition) UN 38.3 — Manual of Tests and Criteria, Part III, Section 38.3 (lithium battery testing) ADR 2023 — European Agreement concerning the International Carriage of Dangerous Goods by Road RID 2023 — Regulations concerning the International Carriage of Dangerous Goods by Rail IMDG Code Amendment 41-22 (sea transport, Constanta port) IATA Dangerous Goods Regulations (DGR) 2024 — PI 965, 966, 967, 968 |
Key gap: Chinese manufacturers must ensure their UN 38.3 test reports are issued under the 8th edition (2023) requirements, including the mandatory Test Summary document format (per IATA 2024 DGR and IMDG 41-22). Test reports from earlier editions may not be accepted at Constanta port or by Romanian customs. State of Charge (SoC) compliance for sea shipment (≤30% SoC for certain cell types) must be documented. ADR road-transport classification and packaging must be verified for Romanian road legs after Constanta discharge.[INFORMATIONAL] UN 38.3 testing (8th edition, 2023) with current Test Summary format is mandatory for BESS lithium battery shipments to Romania via Constanta. ADR compliance is required for Romanian road transport. Exporters must verify that test reports and DG declarations meet current edition requirements before shipment. | Port of Constanta (CN Administratia Porturilor Maritime SA Constanta)2026-06-15 · reference |
| Dangerous Goods Packaging, Marking, Labelling & Documentation — BESS to Romania | Chinese export DG documentation typically follows IMDG and IATA requirements as a baseline (required by carriers), but domestic labelling may follow GB 15258 (general requirements for chemical product safety labels) and GB 190 (dangerous goods packaging marks). These domestic standards do not substitute for ADR 2023 or IMDG 41-22 packaging/labelling requirements. Chinese DG shippers routinely prepare IMDG DGDs but may not prepare ADR documentation for Romanian in-country road transport.GB 15258-2009 — General rules for preparation of chemical product safety label GB 190-2009 — Packaging marks for dangerous goods IMDG DGD (prepared for export by Chinese forwarders) |
Lithium battery BESS shipments to Romania must comply with ADR 2023 (road, including post-Constanta Romanian road legs), IMDG Code 41-22 (sea, Constanta port), and IATA DGR 2024 (air). Requirements include: UN-specification outer packaging; Class 9 lithium battery labels (IATA Label 9A, IMDG Class 9 label); Handling labels (lithium battery mark); Dangerous Goods Declaration (DGD) for sea/air; Multimodal Dangerous Goods Form; Emergency Response Guide (Romanian-language version of ERG 2024 recommended for in-country road transport). State-of-Charge controls and watt-hour thresholds per PI 965-968 must be documented.ADR 2023 — European Agreement concerning the International Carriage of Dangerous Goods by Road (Chapter 3.2 Dangerous Goods List, Chapter 5.2 marking/labelling) IMDG Code Amendment 41-22 — Chapter 5.2, Chapter 6.1 IATA DGR 2024 — Packing Instructions 965, 966, 967, 968 ERG 2024 (Emergency Response Guidebook — Romanian translation recommended for in-country road transport) |
Key gap: ADR 2023 documentation and labelling for Romanian road transport legs is often not prepared by Chinese exporters or their freight forwarders. Romanian hauliers operating from Constanta require ADR-compliant transport documents in Romanian or a language accepted by Romanian authorities. Emergency response information in Romanian is recommended. Chinese domestic DG labels (GB 190) do not satisfy ADR/IMDG marking requirements.[INFORMATIONAL] Chinese BESS exporters must ensure ADR 2023-compliant dangerous goods documents and labelling are prepared for Romanian road transport legs after Constanta port discharge. IMDG 41-22 DGD is required for sea shipment. Chinese domestic DG labels and documentation are insufficient for Romanian/EU transport compliance. Engage a qualified DG consultant or freight forwarder with ADR expertise. | Romanian Road Transport Authority (ISCTR — Inspectoratul de Stat pentru Controlul în Transportul Rutier)2026-06-15 · reference |
