12、teel. The recommendations for the co-ordination of dimensions in building as laid down in BS2900, “Recommendations for the co-ordination of dimensions in building: Glossary of terms”, BS4011, “Recommendations for the co-ordination of dimensions in building: Basic sizes for building components and as

13、semblies”, and PD6444, “Recommendations for the co-ordination of dimensions in building. Co-ordinating sizes of fixtures, furniture and equipment” Part2 (Functional Group5) are embodied, where appropriate, in this standard. Attention is drawn to the Building Regulations1972 in respect of statutory r

14、equirements for urinals Part P (Sanitary conveniences), and to Part M (Drainage and sanitary appliances) of the present Building Standards Scotland (Consolidation) Regulations, in particular the requirements in regulation M15(4)(b) as to the internal diameter of soil pipes serving urinals. It is int

15、ended that “Methods of tests” will follow later, as a separate Part of this standard, and it is hoped to include tests on the following items. 1) Heavy body impact test. 2) Hard body impact test. This standard has been prepared in metric terms in accordance with the metrication programme of the Brit

16、ish Standards Institution. NOTEThe metric values are given in SI units: for further information reference should be made to BS3763, “The International System of units (SI)”. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are resp

17、onsible for their correct application. Compliance 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 to6, an inside back cover and a back cover. This standard has been

18、updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.BS 4880-1:1973 BSI 10-1999 1 1 General 1.1 Scope This British Standard specifies the materials, dimensions and workmanship of stainless steel slab urinals, t

19、ogether with performance requirements. NOTEThe titles of the British Standards referred to in this standard are listed on page 6. 1.2 Supply and fixing The manufacturer shall provide the necessary safeguards and instructions for protection and handling during transport and storage and shall supply d

20、etailed handling and fixing instructions. 1.3 Inspection The purchaser or his representative shall be granted facilities for the purpose of inspection of the finished article to his order prior to delivery. 1.4 Rejection The purchaser shall have the option of rejecting any article purporting to be s

21、upplied to the specifications of this standard, if it fails to meet any of the requirements laid down herein. 1.5 Defects The urinal shall be free from faults affecting function or appearance. 1.6 Marking Every unit shall be clearly and permanently marked so that it can be seen without dismantling t

22、he unit, with the following. 1) The manufacturers name or identification mark. 2) The number of this British Standard, i.e. BS4880 NOTEAttention is drawn to certification facilities offered by BSI; see the inside back cover of this standard. 2 Materials 2.1 General Stainless steel slab urinals shall

23、 be manufactured from stainless steel sheet complying with grades302S17, 304S16, 315S16, and316S16 of BS1449-4. 2.2 Thickness The thickness of stainless steel shall be not less than1.2mm. 3 Design and construction 3.1 Design Stainless steel slab urinals shall be single units or integrated multi-unit

24、s. Units shall comply with the dimensions and permissible deviations shown in Table 1 and Figure 1 andFigure 2. These units shall be designed to operate with cisterns designed to the requirements of BS1876. 3.2 Construction Turned and beaded edges shall be completely sealed to exclude moisture, and

25、there shall be no leakage through the construction. When mild steel or any other metal or metal alloy structural members are introduced to brace and/or stiffen the appliance, they shall be confined to those unseen parts of the appliance not in contact with moisture, and they shall be protected again

26、st corrosion. Attention is drawn to the provisions of CP2008 where applicable. Provision shall be made in the construction of the appliance for the elimination of sound reverberation and drumming on the metal surfaces when it is in use. Where this involves the use of sound deadening materials, they

27、shall be vermin and rot proof and shall be so constructed and attached as to remain in position and be effective throughout the life of the appliance. 3.3 Welding Welding shall comply with the requirements of BS3019-2. 3.4 Finish The exposed surfaces of the urinal shall have a smooth finish of not r

28、ougher than180grit. All welds on the exposed surface shall be similarly ground smooth. When fixed in position, the exposed areas of the back slab, return end, channels and divisions shall have smooth surfaces without ridges and/or crevices which might impede cleaning. 3.5 Divisions The urinals may b

29、e supplied with or without divisions; where divisions are supplied, they shall form an integral part of the appliance and there shall be no space between the back of the division and the back slab to which it is fixed.BS 4880-1:1973 2 BSI 10-1999 3.6 Channels The urinal channel shall have a rounded

30、or “U” section waterway and shall have a fall towards the outlet of not less than1 in100, so as to drain out completely. The channel shall have a capacity of not less than4.5litres per unit, or4.5litres per500mm length of channel. 3.7 Outlets Outlets shall be in the positions shown in Figure 1 and F

31、igure 2 and shall in all cases be suitable for flanges of100mm diameter. 3.8 Waste hole The waste holes shall be recessed and, subject to the tolerances shown, shall conform with the dimensions specified in Figure 2. 4 Flush pipes and spreaders 4.1 Materials Flush pipes shall be manufactured from: 1

32、) Stainless steel tubes complying with the requirements of BS4127. 2) Copper and copper alloy tubes complying with the requirements of BS2871-1 Table X. 3) Plastics tubes complying with the requirements of BS1972 or BS3505. 4.2 Fittings Stainless steel fittings may be used with stainless steel tube

33、and shall be of the grades listed in2.1 plus the grades, 303S21, 303S41, and 304S15 of BS970-4. Copper and copper alloy fittings to be used with copper and stainless steel tubes shall conform to the requirements of BS 864. Appropriate plastics fittings shall be used with plastics tube. Where copper

34、tubes and copper alloy fittings are required to be plated, the plating shall be nickel and chromium to BS1224 (Service condition No.2). 4.3 Spreaders Spreaders shall be made from stainless steel, copper or copper alloy, or plastics. Where copper or copper alloy spreaders are required to be plated, t

35、he plating shall be nickel or chromium to BS1224 (Service condition No.2). Each unit or equivalent length of back slab shall be fitted with a spreader which shall be capable of distributing the flush water evenly over the full length of each unit or equivalent back slab, at a level not less than750m

36、m above the level of the tread and without splashing. 5 Performance requirements for urinal flushing cisterns 5.1 General The arrangement and sizing of flush pipes and spreaders shall be such that they shall not inhibit the free working of the flushing siphon, as described for performance requiremen

37、ts for siphons in BS1876 and, subject to the tolerances quoted for nominal size of cisterns in BS1876, shall deliver4.5litres of water to each unit, or each equivalent length of urinal back slab. 5.2 Height of flushing cistern The height of the flushing cistern shall be compatible with the performan

38、ce requirements for the flushing apparatus within the dimensional limits set in Table 1 of this specification.
