The work of preparing International Standards is normally carried out through ISO technical committees.
10、Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Internat
11、ional Electrotechnical Commission (IEC) on all matters of Electrotechnical Standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council. They are approved in a
12、ccordance with ISO procedures requiring at least 75 % approval by the member bodies voting. International Standard ISO 7176-16 was prepared by Technical Committee ISO/TC 173, Technical systems and aids for disabled or handicapped persons, Subcommittee 1, Wheelchairs. ISO 7176 consists of the followi
13、ng parts under the general title Wheelchairs: Part 1: Determination of static stability; Part 2: Determination of dynamic stability of electric wheelchairs; Part 3: Determination of efficiency of brakes; Part 4: Determination of energy consumption of electric wheelchairs and scooters Theoretical ran
14、ge; Part 5: Determination of overall dimensions, mass and turning space; Part 6: Determination of maximum speed, acceleration and retardation of electric wheelchairs; Part 7: Measurement of seating and wheel dimensions; Part 8: Requirements and test methods for static, impact and fatigue strengths;
15、Part 9: Climatic tests for electric wheelchairs; Part 10: Determination of obstacle-climbing ability of electric wheelchairs; Part 11: Test dummies; Part 13: Determination of coefficient of friction of test surfaces; Part 14: Power and control systems for electric wheelchairs Requirements and test m
16、ethods; Part 15: Requirements for information disclosure, documentation and labelling; Part 16: Resistance to ignition of upholstered parts Requirements and test methods. The following parts are also on the programme of work: Part 17: Serial interface for electric wheelchair controllers; Part 18: St
17、air-traversing devices; Part 19: Wheeled mobility devices for use in motor vehicles; Part 20: Determination of the performance of stand-up type wheelchairs; Part 21: Electromagnetic compatibility of powered wheelchairs and motorized scooters Requirements and test methods; Part 22: Setup procedures.

19、 blank BS ISO 7176-16:1997 BSI 09-19991 1 Scope This part of ISO 7176 specifies requirements and methods of test to assess the resistance to ignition by cigarette and match of the materials used in wheelchair upholstered parts. The tests measure only the resistance to ignition by cigarette and match
20、 of the materials tested and not the ignitability of the finished wheelchair. They give an indication of, but cannot guarantee, the ignition behaviour of the finished wheelchair. NOTEThe requirements are minimal and less severe than legal requirements in some countries. Manufacturers are recommended
