Building construction
For example, in Germany the Model Building Code (MBO) defines object types for which fire protection requirements are necessary:
- Infrastructure buildings: e.g. in health care, social services, schools
- High-rise buildings > 22m high
- Commercial buildings > 800m²
- Office and administration buildings > 400m²
- Accommodation > 12 beds
- Restaurants > 40 seats
In addition, there are ordinances and guidelines (e.g. state building codes, school building guidelines) that define the exact requirements for fire protection.
It assesses the fire behaviour of a building material using specific test methods and limit values. In the EU area, it is to be applied for newly introduced products. Compared to DIN 4102-1, it takes a more detailed consideration of the smoke (s = smoke) and droplet (d = droplets) properties of a building material. This consideration is carried out for building material classes A2 to D. Flame-retardant building materials must not continue to burn independently after the source of ignition was removed, i.e. they are self-extinguishing. In the European classification, the building material class indicates the contribution of the building material to the fire.
This is only an orientation classification. The actual building material class can only be determined by testing!
| DIN 4102-1 | EN 13501-1 |
| A1, A2 - non-flammable | A1 - non-flammable A2 - non-flammable / flame-retardant |
| B1 - flame-retardant | B, C - flame-retardant |
| B2 - normal flammable | D, E - normal flammable |
| B3 - highly flammable | F - highly flammable |
s + smoke = smoke emission
s1 - no / hardly any smoke emission
s2 - medium smoke emission
s3 - strong smoke emission
d + droplets = burning dripping / falling off
d0 - no dripping / falling off
d1 - limited dripping / falling off
d2 - heavy dripping / falling off
The test standards EN 13823 SBI (Single Burning Item, thermal impact of a single burning item for construction products) and EN ISO 11925-2 (Flammability of products when directly exposed to flame - Part 2: Single flame test) apply for the classification within class B, C and D. The classification is made on the basis of the limit values.
Rail
The hazard level (HL) is determined by the combination of operating class and type class. There are the categories HL1, HL2 and HL3, whereby HL3 is the highest hazard level. The HL is specified by the operator, often HL3 is required to guarantee maximum possible safety.
Operating class | Type classes | |||
| N: Standard vehicles | A: Automatic driving mode | D: Double-decker vehicles | S: Sleeping cars and couchettes | |
Surface 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 mapped in 26 sets of requirements (e.g. R1, R22, R24, ...). These are dependent on the type of use (function) and installation location. In some cases there is a list of components. For other components, exposed area, combustible mass and environment are considered. Each set of requirements consists of defined test procedures and specific limit values (depending on HL1, HL2, HL3). The set of requirements is specified by the operator. An R-requirement defines e.g. oxygen consumption, heat output and toxicity.
