Building construction
In Germany, for example, the Model Building Code (MBC) defines property types for which fire protection requirements are necessary:
- Infrastructure buildings: e.g. in healthcare, social services, schools
- High-rise buildings > 22m height
- Commercial buildings > 800m²
- Office and administration buildings > 400m²
- Accommodation establishments > 12 beds
- Restaurants > 40 seats
There are also regulations and guidelines (e.g. state building codes, school building guidelines) that define the exact fire protection requirements.
It evaluates the fire behaviour of a building material using specific test methods and limit values. In the EU, it must be applied to newly imported products. In comparison to DIN 4102-1, it takes a more detailed look at the smoke (s = smoke) and droplet (d = droplets) properties of a building material. This applies to building material classes A2 to D. Flame-retardant building materials must not continue to burn independently after the ignition source has been removed, i.e. they are self-extinguishing. In the European classification, the building material classification indicates the contribution the building material makes to fire.
This is only a guide classification. The actual building material classification can only be determined by testing!
| DIN 4102-1 | EN 13501-1 |
| A1, A2 - non-combustible | A1 - non-combustible A2 - non-combustible / flame-retardant |
| B1 - flame-retardant | B, C - flame-retardant |
| B2 - normally inflammable | D, E - normally inflammable |
| B3 - highly inflammable | F - highly inflammable |
s + smoke = smoke development
s1 - no / hardly any smoke development
s2 - medium smoke development
s3 - strong smoke development
d + droplets = burning droplets / dripping
d0 - no droplets / dripping
d1 - limited droplets / dripping
d2 - strong droplets / dripping
For classification within Class B, C and D, the test standards EN 13823 SBI (Single Burning Item, building products exposed to the thermal attack by a single burning item) and EN ISO 11925-2 (Ignitability of products subjected to direct impingement of flame – Part 2: Single-flame source test) apply. The classification is made on the basis of the limit values.
Rail
The hazard level (HL) is determined by the combination of operating category and design category. There are categories HL1, HL2 and HL3, with HL3 being the highest hazard level. The HL is specified by the operator; often HL3 is required to guarantee maximum possible safety
Operating category | Design categories | |||
| N: Standard vehicles | A: Automatic vehicle operation | D Double-decker vehicles | S: Sleeping car and couchette car | |
Overground vehicles | HL1 | HL1 | HL1 | HL2 |
| Tunnel <= 5 km | HL2 | HL2 | HL2 | HL2 |
| Tunnel > 5 km | HL2 | HL2 | HL2 | HL3 |
| Tunnel, side evacuation not possible | HL3 | HL3 | HL3 | HL3 |
Fire protection requirements for all components are classified into 26 requirement sets (e.g. R1, R22, R24, ...). These depend on the type of use (function) & installation location. Some include a list of components. For other components, the exposed area, combustible mass and environment are considered. Each requirement set consists of defined test procedures and specific limit values (depending on HL1, HL2, HL3). The requirement set is specified by the operator. An R-requirement defines the oxygen consumption, heat output and toxicity, for example.
