13、ber 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. International organizations, governmen

14、tal 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 given in the ISO/IEC Direct

15、ives, Part 2.The main task of technical committees is to prepare International Standards. 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 least 75 % of the member bodies

25、 important to ensure that wheelchair batteries and chargers are suitable for the purpose and that the wheelchair, batteries and charger are compatible. It is also important to ensure that risks arising from the use of wheelchair batteries and their chargers are eliminated or reduced as far as is pra

26、cticable. Consequently, it is essential that performance requirements and safety requirements for wheelchair batteries and battery chargers are available.Battery chargers are divided into three types: off-board, carry-on and on-board. Operating, transport and storage situations can differ for these

27、types, so it is appropriate to apply different requirements to them.vi ISO 2013 All rights reservedCopyright British Standards Institution Provided by IHS under license with BSI - Uncontrolled Copy Not for ResaleNo reproduction or networking permitted without license from IHS-,-,-BS ISO 7176-25:2013

28、INTERNATIONAL STANDARD ISO 7176-25:2013(E)Wheelchairs Part 25: Batteries and chargers for powered wheelchairsWARNING This part of ISO 7176 calls for the use of procedures that might be injurious to health if adequate precautions are not taken. It refers only to technical suitability and does not abs

29、olve those carrying out or commissioning the tests from legal obligations relating to health and safety. Prior to carrying out tests that could cause batteries or chargers to exhibit dangerous behaviour, it is recommended that the likely outcome is assessed and appropriate arrangements made to minim

30、ise risk.1 ScopeThis International Standard specifies requirements and test methods for batteries and battery chargers intended for use with electrically powered wheelchairs. It is applicable to lead acid batteries and chargers intended for use with them. Requirements for chargers are applicable to

31、those with a rated input voltage not greater than 250 V a.c. and a nominal output voltage not greater than 36 V.NOTE 1 Requirements for other battery chemistries (nickel and lithium based batteries) and suitable chargers are under consideration.NOTE 2 Requirements regarding safety are applicable to

32、all battery chargers intended for use with electrically powered wheelchairs.2 Normative referencesThe following referenced documents are indispensable for the application of this document.
