Building Regulations 2015​

Building work in new and altered buildings in Denmark

The Building Regulations contain the Danish rules for building work in new buildings, extensions, conversions and other rebuilding work, as well as changes in the use of buildings that are important in relation to the Danish Building Act or the Building Regulations, the demolition of buildings and alterations and other rebuilding work that may affect the consumption of energy in the building. The Building Regulations apply to building work carried out in the Danish market.

Their primary field of application is multi-storey buildings for residential purposes and all kinds of commercial, industrial and institutional buildings, including the categories listed in section 11 of the Danish Building Act, single-family houses for permanent residence, either as detached single-family houses or linked single-family houses, holiday homes in summer house areas, allotment sheds, campsite cabins and garages, outbuildings, and other secondary buildings.

Scope

This standard specifies the characteristics, performance requirements and test methods for portable fire extinguishers.
Reference to the suitability of an extinguisher for use on gaseous fires (class C fires) are at the manufacturer"s discretion, but are applied only to powder type extinguishers which have gained a class B or class A and class B rating.
Suitability of extinguishers for use on class D fires (fires involving flammable metals) is outside the scope of this standard in respect of test fires. However, extinguishers claiming class D suitability are covered in all other respects by the requirements in this standard for powder extinguishers.
It is considered hazardous for powder and carbon dioxide fire extinguishers to be used on Class F fires. For this reason powder and carbon dioxide fire extinguishers are excluded for conformance with regard to Class F in this European Standard.
NOTE – The extinction of a metal fire presents a situation so specific (in terms of the metal itself, its form, the configuration of the fire etc.) that it is not possible to define a representative standard fire for the purposes of testing. The efficiency of extinguishers on class D fires needs to be established on a case by case basis.
