8、on of the Building Services Standards Committee. It was originally proposed by the British Plastics Federation to provide performance requirements for dustbins manufactured from plastics materials. Such dustbins are being used increasingly and are suitable for use with all normal household waste exc
9、ept hot ashes. It supersedes BS4998:1974 which is withdrawn. This revision differs from the earlier edition in only specifying requirements for dustbin bodies made of thermoplastics materials. In particular, the requirements for the amount of rework material permitted, the dimensions of the dustbins
10、 and the appropriate test loads have been changed. The standard now specifies a maximum mass for the dustbin body. Requirements for dustbin lids will be specified in a forthcoming British Standard. Certification. Attention is drawn to the certification facilities described on the inside back cover o

Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This do

13、I 10-1999 1 1 Scope This British Standard specifies requirements for the dimensions, materials, design and performance of moulded dustbins (excluding lids) manufactured from thermoplastics materials suitable for use with normal household refuse except hot ashes, and having capacities from0.05m 3to0.
14、12m 3 . This standard does not take account of: a) whether the dustbin is to be used in conjunction with a bin liner; b) the special design requirements necessary if the dustbin is to be subjected to regular dragging or rolling as part of a collection system. NOTEThe title of the publication referre
15、d to in this standard is given on the inside back cover. 2 Definitions For the purposes of this British Standard the following definitions apply. 2.1 thermoplastics a plastics material capable of being repeatably softened by heat and hardened by cooling 2.2 capacity the volume of liquid the dustbin
16、contains when it is filled to the brim 3 Materials 3.1 The dustbin shall be produced from a formulated and compounded thermoplastics material. If rework material is used, it shall not constitute more than30% of the total material and shall be the manufacturers material, of the same type, in accordan
17、ce with this standard. No other rework material shall be used. 3.2 The body handles shall be made either from metal or from a thermoplastics material complying with3.1. Metal handles and any associated fastenings shall be protected from corrosion, and shall show no pitting when tested in accordance
18、with BS5466-1 for a period of96 1h. Staining shall not constitute a failure. 4 General dimensions 4.1 The internal height and the internal diameter of the dustbin shall comply with Table 1, as appropriate. 4.2 The sidewalls of the dustbin shall taper from top to bottom. The taper and the position of
19、 the handles shall be such that, when one dustbin is stored inside another, the degree of nesting shall be not less than half the height of a dustbin. 5 Mass The maximum mass of the dustbin shall be5kg. Table 1 General dimensions 6 Design 6.1 Body The internal form and surface of the dustbin shall b
20、e such that it will not trap the contents when the dustbin is being emptied. The body shall be smooth and free from flashes and shall have no sharp edges. 6.2 Base The base shall have a projection or indentation of depth15mm minimum and length100mm minimum, positioned vertically below each body hand
21、le, and not more than50mm inward from the intersection of the side wall of the body and the base, which shall provide a finger grip. NOTEA suitable finger grip may be provided by means of raised cross hatching or radial ribs. 6.3 Body handles 6.3.1 Each dustbin shall be fitted with two diametrically
22、 opposite body handles, situated above the centre of gravity of the empty dustbin. 6.3.2 Each body handle shall be shaped so as to give a hand hold. A rigid test block of the dimensions shown in Figure 1 shall pass freely through each handle along a minimum length of105min. 6.3.3 The gripping part o
23、f the handles shall have no sharp corners or edges. 6.3.4 When tested in accordance with the method described in Appendix B and using the test rig layout given in Appendix A, there shall be no visible weakening of the attachments and no permanent distortion or splitting to the main body of the dustb
24、in. After a minimum period of30min from the end of the test, a rigid test block of the dimensions shown in Figure 1 shall pass freely through each handle along a minimum length of105mm.
