fischer Catalogue Installation Systems Fire protection. Fire protection in pipe installations according to the latest standards · Fire-proof installations for individual pipes and pipe routes from R30 - R120 or F30 to F120. · Proof of compliance with the criteria of MLAR (German standard pipe system directive) for installation in escape and rescue routes Permissible deformation of mounting rails or pipe clamps, for example, was determined. The necessity for these considerations arises from the properties of the steel, which at 30 minutes is subjected to a temperature of >800 °C according to the standard temperature curve (ISO curve). Reduction factors kθ 1,0 Fire protection - protection goals Firstly, fire protection serves to protect people, and is regulated by the building laws in the respective countries (or regional states). Secondly, fire protection serves to protect property and this is regulated by the insurance associations, such as VdS and FM. These requirements partially go beyond the building legislation. This is particularly evident in the installation of fire protection systems, such as sprinklers, etc., as approved or recognised components must be used here.

Personal protection is defined in the MLAR Directive through clear rules for escape routes, such as corridors, stairwells and hallways between stairwells and the exit. The key message is to ensure the safety of the escape route by ensuring the functioning of the fire-proof sub-ceiling. To this end, compliance with the minimum distance of min a ≤ 50 mm according to MLAR is required between installations and underlying suspended fire-proof F30 sub-ceilings (fire resistance of 30 minutes). Based on the fire inspections, load information for a fire resistance of 30 minutes in relation to the maximum 464 Dependency of the yield strength, proportional limit and elasticity module on the temperatutre (basis: EN1993-1-2:2012-12 Eurocode 3). Additionally, the same information is documented in the inspection reports for a fire resistance rating of R30, R60, R90 and R120 according to EN1363-1 and DIN4102-2.
