It was prepared by Technical Committee CW/41, Child use and care articles. A list of organizations represented on thiscommittee can b

13、e obtained on request to its secretary.Information about this documentThis is a new standard, which has been written to cover childrens beds that fall outside the scope of BS EN 716.Use of this documentIt has been assumed in the preparation of this British Standard that the execution of its provisio

14、ns will be entrusted to appropriately qualified and experienced people, for whose use it has been produced.Presentational conventionsThe provisionsof this standard are presented in roman (i.e. upright) type. Its requirements are expressed in sentences in which the principal auxiliary verb is “shall”

15、.Commentary, explanation and general informative material is presented in smaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publication does not purport to include all the necessaryprovisions of a contract. Users are responsible for its correct

16、 application.Compliance with a British Standard cannot confer immunity from legal obligations.SupersessionBS 8509:2008+A1:2011 supersedes BS 8509:2008, which is withdrawn.The start and finish of text introduced or altered by Amendment No. 1 is indicated in the text by tags !and“. Minor editorial cha

17、nges are not tagged.The beds covered by this standard are of two types, suitable for different age groups. These are cot beds and toddler beds, suitable for children from 18 months to 4 years, and junior beds suitable for children over 4 years. In BS 8509:2008+A1:2011, different permissible gap size

18、s are specified for these two bed types. This is to align the gap size requirements for junior beds with those for bunk beds specified in BS 8509:2008+A1:2011BS EN 747 with regard to entrapment of the head and neck and entrapment in the bed base. The committee are aware that there is a paradox betwe

19、en the head probes used for testing gap sizes in cot beds and toddler beds and those used for testing gap sizes in junior beds, in that a smaller head probe is used to test beds for older children than is used to test beds for younger children. The head probes used for testing cot beds and toddler b

20、eds are considered to be more realistic. However, for the purposes of aligning with existing European Standards these have not been adopted for testing junior beds.Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 07/07/2011 07:28, Uncontrolled Copy, (c) BSIiv BSI 2011 This page deliberately le
