11、y published as BS3980. However, while the metricated version of BS3980 was being prepared, it was decided that it would be logical to issue the revised edition as Part5 of BS5041 “Fire hydrant systems equipment”. Parts1 to4 of BS5041, the titles of which are given below, are at present in course of
12、preparation. Part 1: Landing valves for wet risers; Part 2: Landing valves for dry risers; Part 3: Inlet breechings for dry risers; Part 4: Boxes for landing valves for dry risers. This standard was originally proposed by the London Fire Brigade and has been prepared under the authority of the Fire
13、Standards Committee to provide detailed specifications for most of the special requirements for wet and dry risers and foam inlets described in BS5306-1. This part of BS5041 supersedes BS3980:1966 and is intended to fulfill the same purpose as that standard, that is, to define the standard sizes and
14、 details of boxes for foam inlets and dry riser inlets so as to enable architects and builders to specify a standard product in metric terms. The metric values are given in SIunits; for further information on these, reference should be made to BS3763 “The International System of units (SI)”. The wor
15、k sizes have been selected to conform to the first or second preferences in BS4011 “Recommendations for the co-ordination of dimensions in building. Basic sizes for building components and assemblies” and this has led to a slight reduction in the maximum permissible size of the box compared with tha
16、t specified in BS3980. The boxes can also be used for other purposes, e.g.for fuel oil inlets and inlets for drencher systems. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Complian
17、ce with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pagesi andii, pages1 to4, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had a
18、mendments incorporated. This will be indicated in the amendment table on theinside front cover.BS5041-5:1974 BSI 04-1999 1 1 Scope This British Standard specifies the requirements for boxes for foam inlets or dry risers manufactured in a choice of materials to suit a particular application. NOTEThe
19、titles of the British Standards referred to in this Standard are listed on the inside back cover. 2 Definitions For the purposes of this British Standard the following definitions apply: 2.1 Box a box containing the inlets of foam pipes or water mains, installed in, or within the boundaries of the s
20、ite of a building, preferably recessed in a wall with inlets normally at street level through which foam or water can be pumped to provide a supply at discharge points situated at various levels in the building 2.2 Dry riser a vertical pipe installed in a building for fire fighting purposes, fitted
21、with inlet connections at the base and with landing valves at specified points, which is normally dry but which is capable of being charged with water by pumping from fire service appliances 3 Manufacture 3.1 Box. The box shall be of robust construction with seamed edges to guard against the ingress
22、 of water. The bottom of the box shall be provided with a fall of not less than1 in12 and be suitably drained. The box shall be supplied with flanges not less than38mm wide on the external face (seeFigure 1 and Figure 2). The back of the box shall be provided with suitable holes to accommodate foam
23、inlets (of diameter65 mm or80mm) or dry risers (of diameter100 mm or150mm) (see BS4504). When there is more than one foam inlet in one box they shall be spaced at not less than175 mm centres. The box shall be supplied with suitable fixing lugs or screw holes in the back of the box to enable it to be
24、 built into position. 3.2 Door. The frame of the door shall be of rigid construction and designed to accommodate a spring lock. The door shall be side hung and shall open through approximately180 . The box shall have a striking plate to engage the lock when the door is closed. The spring lock shall
25、be such that it can also be operated and opened from the inside without the aid of a key when the glass has been broken. The front of the door shall be glazed. The glazed portions of the door shall be large enough to enable delivery hose(s) or foam branch pipe(s) to be connected to the inlet(s) even
26、 if the door cannot be opened and the only means of access is by breaking the glass. 3.3 Hinges. The hinges shall be of the butt type and be so fixed that, in the event of damage, they can be removed and replaced with the box remaining in situ. 3.4 Glass fixing. The door shall be provided with remov
27、able rebated frame for housing the glass. The rebated frame shall be attached to the door with brass screws and nuts. 3.5 Lock. The lock shall be a spring cylinder lock (with key) capable of being released from the inside without the use of the key. The lock shall not be fitted with a safety catch.
28、The lock shall be secured to the door frame by suitable means so that in the case of damage it can be removed and replaced. 3.6 Opening device. The external face of the door shall be provided with a countersunk finger hole to facilitate opening the door. 3.7 Designation 3.7.1 On glass front. The ins
29、ide surface of the glass panel of the box shall be marked with the words “Dry riser inlet(s)” or “Foam inlet(s)” as appropriate. The sign shall comply with the requirements for fire equipment signs in BS5499-1. The sign shall be rectangular, the wording shall be in white and the background red. The
30、letters shall be in lower case except for the initial letter “D” or “F”, which shall be in upper case. The letter height shall be either: 1) not less than50 mm; or 2) of such smaller size as may be necessary because of the size of the glass panel. 3.7.2 On indicator plates. An indicator plate or pla
31、tes (about100 mm 75 mm in size) shall be fixed within or on the outside of, or shall be provided for fixing adjacent to the inlet box to indicate the room or rooms with which the foam inlet(s) communicates. Where more than one inlet communicates with one compartment the position in the compartment s
32、hall be indicated. The sign(s) shall comply with the requirements for fire equipment signs, or for supplementary signs, in BS5499-1. They shall be rectangular, and the wording shall be in white and the background red or the wording shall be in black and the background white. The letters shall be in
33、lower case except for the initial letter, which shall be in upper case. 4 Materials and thickness 4.1 Box 4.1.1 The material used for the manufacture of the box shall be selected by agreement between the purchaser and the manufacturer from the following: 1) Rust proof steel (either galvanized, zinc
34、sprayed or metal coated) 2) Stainless steel to comply with the requirements of BS1449-4BS5041-5:1974 2 BSI 04-1999 3) Brass to comply with the requirements of the series BS2870 to BS2875 for wrought material and BS1400 for cast material 4) Aluminium alloy to comply with the requirements of BS1490 or

45、BS5041-5 on or in relation to a product is a claim by the manufacturer that the product has been manufactured to the requirements of the standard. The accuracy of such a claim is therefore solely the manufacturers responsibility. Enquiries as to the availability of third party certification should b
46、e addressed to the appropriate certification body.
