7、oreword This British Standard forms one of a series relating to tubular-framed equipment for hospitals. This revision uses the metric system of measurement and provides only one basic screen in the interest of simplification and economic buying. The recommendations on which this British Standard was
8、 originally based formed part of a comprehensive report on the screening of hospital patients. The sections of the report relating to other forms of screening, such as curtains and fixed or folding partitions, were considered inappropriate as a basis for detailed specifications, but it was thought t
9、hat the report as a whole might be of assistance in the planning of hospital wards, and it was decided to publish it in the form of a guide. It was accordingly issued as BS1805 “Notes on methods of screening hospital patients”. In view of the wide variety of materials and types of curtaining now ava
10、ilable, it is left to the purchaser to decide on the type of infilling used in the panels. Wherever possible this should conform to the performance requirements of flameproof materials as defined in BS3120 “Performance requirements of flameproof materials for clothing and other purposes”. A British
11、Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible 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 co
12、ver, 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 amendments incorporated. This will be indicated in the amendment table on the inside front cover.BS1895:1973 BSI 12-1999 1 1 Scope This Br
13、itish Standard specifies the materials, dimensions, constructional requirements and finish for metal-framed wheeled screens. Information which should be supplied by the purchaser with an enquiry or order is given inAppendix A. NOTEThe titles of the British Standards referred to in this standard are
14、listed on page 4. 2 Materials The framework shall be of mild steel tube, complying with the requirements of any of the types and grades specified in BS1775. The tubing shall be of19mm outside diameter and not less than1.0mm in wall thickness. The legs of the framework shall be19mm outside diameter a
15、nd not less than1.2mm in wall thickness. 3 Dimensions The dimensions of the screen shall be as shown inFigure 1 and the framework of the screen shall comprise four panels, each panel being610mm wide. The panels shall be mounted on castors attached to tubular supports, as shown inFigure 1 giving an o
16、verall height of1680mm for the screen. The tolerance on dimensions shall be5mm. 4 Construction 4.1 Framework. Each panel of the framework shall consist of a tubular frame with radiused corners. The framework shall be constructed so that each panel will fold flat on its neighbour. If separate curtain
17、s are to be used in the panels, fittings, such as four hooks welded to the inside of the panel, shall be provided. Expanding wires or other means for supporting the curtains may be supplied by agreement between the purchaser and the manufacturer. The main details of the framework for screens shall b
18、e as shown inFigure 1. 4.2 Hinges. Each pair of adjacent panels forming a screen shall be connected by two hinges which provide the following features: 1) smooth unrestricted movement of the panels; 2) parallel adjacent tubes of the hinged panels with a maximum gap of6mm between tubes. 4.3 Castors.
19、A screen shall be supported on nine castors positioned as shown inFigure 1. The castors shall be of the plug fitting type, having screw type axles and swivelling in ball races, and shall comply with the requirements of BS2099-1. The wheels shall be not less than50mm diameter of a non-colour marking,
20、 non-staining composition. The castors shall be so constructed as to obviate clogging by the accumulation of dust and foreign matter. Alternatively, the purchaser may specify that castors shall be of the expanding plug fitting type, having a metal body and nylon or equivalent wheel not less than50mm
21、 diameter. 5 Framework finish 5.1 Before the castors are fitted, the framework shall be finished with a good quality stoving enamel or an epoxide enamel or powder. Prior to applying the finish all rust, grease, scale or other surface adhesions of a like nature shall be removed, all welds shall be pr
22、operly dressed and cleaned up and the surface given a coat of inhibitive primer. 5.2 The finishing coat shall be stoved strictly in accordance with the paint manufacturers stoving schedule and shall provide a dry film thickness of not less than0.025mm. The finish shall be smooth, free from dust, run
23、s and any other such defects. 5.3 The finish shall comply with the following requirements. 5.3.1 Resistance to bend effects. The finish on the test panel shall withstand bending over a12mm diameter mandrel without cracking or loss of adhesion when tested by the method described in BS3900-E1. 5.3.2 S
24、cratch resistance. The finish on the test panel shall not be penetrated when tested in accordance with BS3900-E2 using a needle load of3000g. 5.3.3 Impact resistance. The finish of the test panel shall not rupture when tested in accordance with BS3900-E3. 5.3.4 Resistance to cupping effects. The fin
25、ish of the test panel shall not crack or become detached from the metal substrate when tested in accordance with BS3900-E4. 6 Marking Metal-framed wheeled screens complying with the requirements of this standard shall be plainly and permanently marked with the following particulars: 1) the name, tra
