![]() In July 2015, BS EN 16034: Pedestrian Doorsets, Industrial, Commercial, Garage Doors and Openable Windows. One way of demonstrating that proper materials have been used is by using products bearing CE marking which, under UK legislation (Construction Products Regulations), is mandatory where a harmonised European standard or a European Technical Assessment has been published. Regulation 7 of the Building Regulations 2010 stipulates that building work “shall be carried out with adequate and proper materials which are appropriate for the circumstances in which they are used”. However, the introduction of BS EN 16034 saw new requirements made of manufacturers in relation to the CE marking of their products. ![]() The UK Fire Door and Doorset Industry Group, which represents a cross-section of the fire door industry, has developed the following definitions.Ī doorset is a frame, finished door leaf or leaves, glazed where required, and its necessary hardware, fully machined needing no further site work other than possible reassembly of factory-prepared component parts, and all placed on the market by one legal entity, for fixing in position in an opening in a wall.Ī door assembly is a frame, door leaf or leaves and its necessary hardware, supplied as individual component parts, usually unmachined, and placed on the market by more than one legal entity, for incorporating into an opening in a wall.īoth have the intended use (when closed) of resisting the passage of fire and/or gaseous products of combustion and to those ends must be capable of meeting specified performance criteria.Īs such the specifier should be seeking assurance of the door’s specification, with BS 8214:2016 Code of Practice for Fire Door Assemblies advising that consideration should be given to “the desirability of sourcing fire doors from a manufacturer that operates as a member of a third-party accreditation scheme, as such a scheme will be designed to ensure consistency of product conformity”. The door frame, the hinges, the ironmongery, the glass in the vision panels and the seals are all interdependent upon each other to ensure the effectiveness of the door.įor those specifying fire doors, either for new builds, refurbishments or replacement works, there is normally the option to specify for a doorset or a door assembly. A fire door is much more than just a door leaf. The protection degree of the switchboards is IP 30 from the outside and up to IP20 at open doors.Fire doors are perhaps some of the least understood of all the passive fire protection measures in a building. The FORMS of segregations available are the following:įorm 3a as form 2 and separation of all functional units from each other with the exception of their output terminals (they do not require the separation from the bars)įorm 3b as 3a but with separation of the terminals from the barsįorm 4 as form 3b but also with separation between the output terminals Limiting the probability of accidental activation of arches Protection against contact with active parts which belong to surrounding functional units Copper bars inside a low voltage compartment.ġ Front to equipment, connections and terminal boxĢ Front to equipment and terminals rear to the connectionsĪccording to CEI 17.13, by splitting the equipment by means of barriers or diaphragms in separate cells or compartment fractions you may obtain one or more of the following conditions: Number of columns in lamination sheet 20/10įIG 2. The structure and equipment are connected to the ground and are related to a copper bar suitably sized in relation to the alleged short-circuit current.įIG 1. ![]() Busbars and connections to the switches, encased and in air with calibrations superior than 100 A are made of copper plate with rounded edges and properly supported by bar supports in polyester resin and fiberglass while the connections to the switches of lower calibrations are made of copper wire.
