It is identical with
3、 ISO 11199-1:1999. It supersedes BS4986:1990 and BS5104:1990 which are withdrawn. The UK participation in its preparation was entrusted to Technical Committee CH/38, Walking aids, which has the responsibility to: aid enquirers to understand the text; present to the responsible international/European
4、 committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations represented on this committee can be obtained on request to its secretary. Cross
5、-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Standards which implement these international or European publications may be

22、 standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Internationa
23、l organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules
24、given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least75% of the member bodies casting a vote. International Standard ISO 11199-1
25、 was prepared by Technical Committee ISO/TC 173, Technical systems and aids for disabled or handicapped persons. ISO 11199 consists of the following parts, under the general title Walking aids manipulated by both arms Requirements and test methods: Part 1: Walking frames; Part 2: Rollators. Annex A

When tested
40、 according to the static loading test (5.4), no part of the frame shall crack or break. When tested according to the static leg-strength test (5.5), none of the legs shall crack, break or show any permanent set of more than15mm, measured at the end of the leg. 4.2 Stability When tested according to
41、the forward stability test (5.6), the angle of the plane at the point of walking frame tilting shall be not less than10,0 . When tested according to the backward stability test (5.7), the angle of the plane at the point of walking frame tilting shall be not less than7,0 . When tested according to th
42、e sideways stability test (5.8), the angle of the plane at the point of walking frame tilting shall be not less than3,5 . It is acknowledged that a reciprocal walking frame cannot meet this sideways stability requirement. Therefore, an analysis of the risks related to the instability shall be assess
43、ed by the manufacturer, and appropriate guidance and warnings on limitations for use shall be given.

See also 4.1. The tip shall be replaceable. The tip shall not cause
46、discolouring of the walking surface, as verified by visual inspection. That part of the tip that contacts the walking surface shall have a minimum diameter of35mm. Compliance shall be verified by visual inspection. 4.6 Adjusting devices Each of the height adjustments shall be clearly marked with its
47、 maximum allowable elongation. After the fatigue test (5.3), the adjustment/folding mechanisms shall operate as intended by the manufacturer. Folding walking frames shall lock into working position when unfolded. 4.7 Materials and finish Taking into account the intended use and contact by those invo
48、lved in user care or transportation and storage of the product, walking frame materials which come into contact with the human body shall be assessed for biocompatibility using the guidance given in ISO 10993-1. The walking frame materials shall not cause discolouring of skin or clothing when the fr
49、ame is in normal use. All parts of the walking frame shall be free from burrs, sharp edges or projections that could cause damage to clothing or discomfort to the user. 5 Test methods 5.1 General Walking frames are grouped into six sizes, as given in Table A.1.
