In Romania, European lighting standards are adopted as national standards with the prefix SR (for example, SR EN 12464-1 is EN 12464-1). Their values are identical to the European originals. They are complemented by national technical regulations issued by the Ministry of Development (MDLPA): NP 061 for lighting in buildings and NP 062 for road and pedestrian lighting. This guide is written for manufacturers, distributors and designers working on projects in Romania.
What is different in Romania?
- Same EN standards, plus national regulations. NP 061 and NP 062 apply alongside the EN standards, not instead of them.
- Independent design review. Building designs are checked by certified design reviewers (verificatori de proiecte), as required by Romanian construction law (Law 10/1995).
- Public tenders specify the lighting class. For roads and public spaces, the M, C or P class is usually set in the tender specification (caiet de sarcini), and a DIALux calculation is often requested with the offer.
- Documentation in Romanian. Reports submitted to Romanian authorities must be in Romanian. We deliver studies in English, Romanian or both.
1. EN 12464-1 — Lighting of indoor workplaces
SR EN 12464-1:2021 — Light and lighting. Lighting of work places. Part 1: Indoor work places
The most widely used standard in interior lighting design. It sets the minimum lighting requirements for all indoor spaces where people work.
EN 12464-1 is the reference standard for lighting offices, industrial halls, warehouses, retail spaces, schools, hospitals, hotels and any other indoor space where people carry out activities.
What EN 12464-1 specifies
For each type of space and activity, the standard defines three main parameters:
- Ēm (lx) — maintained average illuminance on the task area: the value below which the average illuminance must not fall during the life of the installation
- UGR — maximum Unified Glare Rating
- Ra — minimum colour rendering index
Key values from EN 12464-1
| Space / activity | Ēm (lx) | UGR max | Ra min |
|---|---|---|---|
| Office with computer work, open-plan | 500 | 19 | 80 |
| Conference room | 500 | 19 | 80 |
| Technical drawing | 750 | 16 | 80 |
| Reception / waiting area | 300 | 22 | 80 |
| Industrial hall, general | 300 | 25 | 80 |
| Inspection / quality control | 1000 | 19 | 90 |
| Storage | 200 | 25 | 60 |
| Picking / sorting | 300 | 25 | 60 |
| Retail sales area | 500 | 22 | 80 |
| Classroom | 500 | 19 | 80 |
| Hospital ward | 300 | 19 | 90 |
| Operating theatre | 1000 | 19 | 90 |
| Restaurant / café | 200 | 22 | 80 |
| Bar / food preparation | 300 | 22 | 80 |
| Underground car park, traffic lanes | 75 | 28 | 40 |
| Car park entrance zone (daytime) | 300 | — | 40 |
Important: EN 12464-1 specifies maintained values: the minimum the installation must deliver throughout its life, after the maintenance factor is applied. DIALux calculations work with these maintained values, not with the initial output of new luminaires.
2. EN 12464-2 — Lighting of outdoor workplaces
SR EN 12464-2 — Light and lighting. Lighting of work places. Part 2: Outdoor work places
Applies to outdoor work areas: construction sites, outdoor storage, freight terminals and industrial yards.
EN 12464-2 complements the first part of the standard for activities carried out outdoors, in particular on construction sites, industrial platforms, port and airport terminals, loading bays and other professional outdoor areas.
Typical EN 12464-2 values
- General outdoor circulation areas: 5–10 lx
- Construction site work areas: 50–200 lx, depending on the visual task
- Loading and unloading areas: 150 lx
- Access control points: 150–200 lx
3. EN 13201 — Road lighting
SR EN 13201 — Road lighting (multi-part series)
The reference standard for lighting roads, streets and public outdoor spaces with vehicle and pedestrian traffic.
EN 13201 defines lighting classes based on road type, speed and traffic. For motorised traffic routes, the main parameter is luminance, not illuminance, because drivers perceive the road surface through the light it reflects.
M classes — motorised traffic (EN 13201-2:2015)
| Class | Typical application | L̄ min (cd/m²) | Uo min | Ul min | fTI max |
|---|---|---|---|---|---|
| M1 | Motorway, high-speed road | 2.00 | 0.40 | 0.70 | 10% |
| M2 | Main national road | 1.50 | 0.40 | 0.70 | 10% |
| M3 | Distributor road, medium speed | 1.00 | 0.40 | 0.60 | 15% |
| M4 | Main local street | 0.75 | 0.40 | 0.60 | 15% |
| M5 | Residential road with traffic | 0.50 | 0.35 | 0.40 | 15% |
| M6 | Low-traffic residential road | 0.30 | 0.35 | 0.40 | 20% |
C classes — conflict areas (intersections, roundabouts, shopping streets with traffic) are based on illuminance: C0 = 50 lx, C1 = 30 lx, C2 = 20 lx, C3 = 15 lx, C4 = 10 lx, C5 = 7.5 lx, all with Uo ≥ 0.40.
P classes — pedestrian and low-speed areas range from P1 (15 lx average) to P6 (2 lx average).
Note: The lighting class is not the designer’s choice. It follows from traffic parameters (CEN/TR 13201-1). In Romania, the municipality or public client usually specifies it in the tender documents, in line with NP 062.
4. EN 1838 — Emergency lighting
SR EN 1838 — Lighting applications. Emergency lighting
The standard for emergency lighting in buildings: escape route lighting, open area (anti-panic) lighting and high-risk task area lighting.
EN 1838 is mandatory for public and industrial buildings in Romania. It defines three types of emergency lighting, each with its own requirements:
1. Escape route lighting
- Minimum illuminance on the centre line of the escape route: 1 lx
- Uniformity: max/min ratio on the centre line not above 40:1
- Response time: 50% within 5 s, 100% within 60 s
- Duration: at least 1 hour (3 hours recommended)
2. Open area (anti-panic) lighting
- Applies to areas larger than 60 m²
- Minimum illuminance: 0.5 lx on the core area
- A 0.5 m border at the perimeter is excluded from the calculation
- Duration: at least 1 hour
3. High-risk task area lighting
- Applies where people or processes are exposed to danger
- Minimum illuminance: 10% of normal maintained illuminance, and at least 15 lx
- Response time: 0.5 s
Mandatory in Romania: emergency lighting is required by law for public and industrial buildings and any space where people gather. Every building design must include an emergency lighting design to EN 1838 alongside the general lighting.
5. EN 12193 — Sports lighting
SR EN 12193 — Light and lighting. Sports lighting
The standard for lighting sports facilities, from recreational training to national and international competitions.
EN 12193 defines lighting classes for each sport — football, tennis, basketball, handball, volleyball, athletics, swimming — with specific values for illuminance, uniformity and glare rating (GR).
EN 12193 classes for outdoor football (horizontal illuminance)
| Class | Level of competition | Ēh (lx) | Emin / Ēh | GR max |
|---|---|---|---|---|
| Class I | National and international competition | 500 | 0.7 | 50 |
| Class II | Regional competition, club matches | 200 | 0.6 | 50 |
| Class III | Training, recreational play | 75 | 0.5 | 55 |
Televised matches need more: vertical illuminance towards the cameras, set by broadcaster and federation requirements (UEFA, FIFA), on top of EN 12193.
6. NP 061 and NP 062 — Romanian national regulations
NP 061-02 — Regulation for the design and execution of artificial lighting systems in buildings
The national regulation for lighting in Romanian buildings. It complements the EN standards with requirements specific to Romanian law and practice.
The main topics covered by NP 061:
- EN 12464-1 is mandatory for interior lighting
- Emergency lighting must follow EN 1838
- Rules for combining daylight and artificial light
- Requirements for lighting controls
- Energy efficiency of lighting installations
- Specific requirements for different building categories
NP 062-02 — Regulation for the design of road and pedestrian lighting systems
The national regulation for street, road, tunnel and pedestrian lighting. Approved in 2002 and amended by MDLPA Order 2837/2022, it applies together with the EN 13201 series on public lighting projects.
Summary — which standard applies where
| Standard | Applies to | Main parameters |
|---|---|---|
| SR EN 12464-1 | Any indoor workplace | Ēm (lx), UGR, Ra |
| SR EN 12464-2 | Outdoor workplaces | Ēm (lx), Uo, GR, Ra |
| SR EN 13201 | Roads, streets, public spaces | L̄ (cd/m²), Uo, Ul, fTI |
| SR EN 1838 | Emergency and escape lighting, all buildings | Emin (lx), response time, duration |
| SR EN 12193 | Sports facilities | Ēh (lx), uniformity, GR |
| NP 061 | All buildings in Romania | Complements the EN standards |
| NP 062 | Road and pedestrian lighting in Romania | Complements EN 13201 |
In practice: a compliant building project in Romania meets EN 12464-1 for general lighting, EN 1838 for emergency lighting and NP 061 as the national regulation. Roads follow EN 13201 and NP 062; sports facilities follow EN 12193. All values are verified by photometric calculation in DIALux Evo.
