9、1999 Foreword This Part of BS2588 has been prepared under the direction of the Health Care Standards Policy Committee The first edition of BS2588, which was published in 1955, was prepared at the request of the Hospital Equipment Standards Advisory Committee of the British Standards Institution. In
10、that edition, only the adult size Perfection 1)type of bed pan was specified. When considering the revision of BS2588:1955, it was confirmed that the design criteria for bed pans were not wholly applicable to the portable sanitary pans to be used with commode chairs. Accordingly, it was agreed that
11、the new edition of BS2588 should be prepared in two Parts with Part1 specifying the requirements for bed pans, and this Part (Part2) specifying two types of portable pan for use in commode chairs. Type1 pans are designed with a lip which rests on supporting bearers in the commode chair. Type2 pans a
12、re designed with the base supported by a level surface at between100mm and150mm beneath the commode seat. The sizes of the pans are compatible with the dimensions specified for WC seats specified in BS1254, and with bed pan washer disinfectors specified in BS2745. NOTEAlthough this specification has
13、 not been drafted to cover portable commode pans for use with mobile sanitary chairs complying with BS4751 which have been fitted with a suitable cradle or support frame, the commode pans are capable of use with such chairs. Also a pan specified in this Part of BS2588 may be used as a bed pan but it
14、 should also comply with the requirements of Part1. Two grades of bed pan are specified. Grade A pans, which are capable of withstanding heat sterilization at134 C, are specified for those who need a sterilizable pan; grade B pans, which will withstand heat disinfection at100 C, are satisfactory for
15、 most purposes. This Part of BS2588 specifies performance and marking requirements for reusable pans for commode chairs. It also specifies the surface finish as the quality of finish is of particular importance from the standpoint of ease of cleaning and disinfection and of resistance to corrosion.
16、It has been assumed in the drafting of this standard that the tests for assessing compliance will be carried out by those who are appropriately qualified or under the supervision of experienced personnel. If the quality of a product can be assured only by in-process control, the user of this standar
17、d may wish to consider product certification. Where in-process quality control is not appropriate the user of this standard may wish to consider assessed capability. Product certification. Users of this British Standard are advised to consider the desirability of third party certification for produc
18、t conformity with this BritishStandard based on testing and continuing surveillance, which may be coupled with assessment of a suppliers quality systems against the appropriate Part of BS5750. Enquiries as to the availability of third party certification schemes will be forwarded by BSI to the Assoc
19、iation of Certification Bodies. If a third party certification scheme does not already exist, users should consider approaching an appropriate body from the list of Association members. Assessed capability. Users of this British Standard are advised to consider the desirability of assessment and reg
20、istration of a suppliers quality systems against the appropriate Part of BS5750 by a third party certification body. 1) “Perfection” is a term widely recognized by the industry concerned to indicate a specific shape of bed pan.BS2588-2:1992 BSI 08-1999 iii A British Standard does not purport to incl
21、ude 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 cover, an inside front cover, pages

23、materials, construction and performance requirements for reusable sanitary pans intended for use with commode chairs. Grade A pans are designed to withstand heat sterilization at134 C; gradeB pans are capable of withstanding heat disinfection at100 C. NOTE 1Appendix A gives details of the informatio
24、n to be supplied by the purchaser to the manufacturer. NOTE 2The titles of the publications referred to in this standard are given on the inside back cover. 2 Definitions For the purposes of this British Standard the following definitions apply. 2.1 portable sanitary pan a receptacle or container de
25、signed to collect human waste and to enable its subsequent safe transport to a place for disposal of the waste 2.2 disinfection the process used to reduce the number of viable micro-organisms in a product but which may not necessarily inactivate some viruses and bacterial spores 2.3 sterilization th
26、e process used to render a product free from viable micro-organisms 2.4 commode chair a chair designed with a seat, with an aperture, under which may be fitted a portable sanitary pan 2.5 commode pan a portable sanitary pan designed for use in a commode chair 3 Classification of commode pans 3.1 Typ
27、es Commode pans shall be classified as follows: a) type1 for pans provided with a rim which is intended to rest on supporting bearers in the commode chair (e.g.with the seat raised or removed, the pan may be lowered onto the bearers or, with the seat in place, the pan may be slid horizontally on to
28、the bearers); b) type2 for pans intended to rest on a level surface beneath the seat of a commode chair (e.g.the pan may be slid horizontally beneath the aperture in the chair seat or the seat may be lowered over the pan). 3.2 Grades Commode pans and, if fitted, their lids shall be graded as follows
29、: a) gradeA for pans capable of withstanding heat sterilization at a minimum of134 C; b) gradeB for pans capable of withstanding heat disinfection at100 1 C. 4 Materials 4.1 Plastics materials Plastics materials used for the construction of any part of the commode pan shall comply with the requireme
30、nts given in Table 1.
