11、SI 11-1999 Foreword This British Standard was prepared at the request of the British Plastics Federation and authorized by the Surgical Instrument and Medical Appliances Standards Committee of BSI. The standard has been prepared to establish acceptance standards for plastics hollow-ware for use in h
12、ospitals and other health service areas. Requirements for quality and finish are laid down to ensure that articles give a satisfactory performance for their stated use within the range of this specification. BS1823 deals with stainless steel hollow-ware for use in hospital operating theatres and war
13、ds. At elevated temperatures, plastics material may suffer deformation under stress and care should be taken in the packaging of the articles and in the loading of them into the sterilization chamber. When flammable anaesthetics are used, hollow-ware from plastics materials capable of generating and
14、 retaining electrostatic surface charges should not be brought within0.25m of any part of an anaesthetic breathing circuit. 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. Compliance
15、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 to10, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had ame
16、ndments incorporated. This will be indicated in the amendment table on the inside front cover.BS5452:1977 BSI 11-1999 1 1 Scope This British Standard specifies requirements for hospital hollow-ware made of plastics materials.

There shall be two sizes of graduated measuring jugs, namely500ml
27、 and1000ml capacity, corresponding to the top graduation mark. To minimize the risk of spillage in use, there shall be sufficient ungraduated depth at the top of the jug. 5.8.2 Marking of capacity. Jugs shall be graduated externally in50ml increments.

Measuring jugs shall be of circular cross section with the sides tape
29、ring towards the base, such that the slope lies between0.5 and9 as shown inFigure 7. 5.8.3.2 Stability. The ratio of the height, B, of the jug to its base diameter, A, shall not exceed2 : 1 as indicated inFigure 7. 5.8.3.3 Rim. If desired, the rim of the measuring jug may be provided with an outer r
30、einforcing ring integral with the body of the jug. An internal reinforcing ring shall not be used. 5.8.3.4 Handles.

32、e shall be free from moulding defects causing surface irregularities. 8 Covers Covers to vessels are optional. If required for instrument trays, kidney dishes, lotion bowls, gallipots and jugs, the covers shall be of such a size and shape that they fit the relevant vessel. The sizes of the covers sh
33、all be such that they are made to correspond to the maximum tolerances of the vessels that are to fit. The covers shall be designed with an integral rim so that they shall be retained in place when the relevant vessel is tilted in any direction to an angle of60 from the horizontal. Covers should be
34、produced with a suitable handle. The material of construction, the finish and the workmanship shall comply with the requirements of clauses4, 6, 7, 9 and10. 9 Impact resistance At room temperature(20 5 C) the article shall be capable of withstanding a free fall from a height of1.25m onto a concrete

41、hin a sterilization bag. Paper and bags used shall be of approved quality for steam sterilization. Each package shall be subjected to50 sterilization cycles in a sterilizer operating at134+4, 0 C in accordance with BS3970-1. During the tests the articles shall not be otherwise stressed or loaded. Ap

The hollow-ware shall be lifted vertically from the surface and held for10s. Jugs shall be held by the
43、handle. Other hollow-ware shall be gripped in either Cheatles forceps (complying with the requirements of BS2905) or Harrisons bowl forceps (complying with the requirements of BS3204), as appropriate, so that the jaws face downwards over the rim of the article. For the wash bowl and large instrument
