IS 18651 : Part 21 : 2025/ISO 7176-21 : 2009 Wheelchairs - Part 21 Requirements and Test Methods for Electromagnetic Compatibility of Electrically Powered Wheelchairs and Scooters and Battery Chargers
| ICS 11.180.10; 33.100.01 | MHD 09 |
NATIONAL FOREWORD
This Indian Standard (Part 21) which is identical to ISO 7176-21 : 2009, 'Wheelchairs - Part 21 Requirements and test methods for electromagnetic compatibility of electrically powered wheelchairs and scooters, and battery chargers' issued by the International Organization for Standardization (ISO), was adopted by the Bureau of Indian Standards on the recommendation of the Artificial Limbs, Rehabilitation Appliances and Equipment for the Persons with Disability Sectional Committee and approval of the Medical Equipment and Hospital Planning Division Council.
This standard is published in various parts. The other parts in this series are:
| Part 1 | Determination of static stability |
| Part 2 | Determination of dynamic stability of electrically powered wheelchairs |
| Part 3 | Determination of effectiveness of brakes |
| Part 4 | Energy consumption of electric wheelchairs and scooters for determination of theoretical distance range |
| Part 5 | Determination of dimensions mass and manoeuvring space |
| Part 6 | Determination of maximum speed of electrically powered wheelchairs |
| Part 7 | Measurement of seating and wheel dimensions |
| Part 8 | Requirements and test methods for static impact and fatigue strengths |
| Part 9 | Climatic tests for electric wheelchairs |
| Part 10 | Determination of obstacle-climbing ability of electrically powered wheelchairs |
| Part 11 | Test dummies |
| Part 13 | Determination of coefficient of friction of test surfaces |
| Part 15 | Requirements for information disclosure documentation and labelling |
| Part 19 | Wheelchairs for use as seats in motor vehicles |
| Part 22 | Set-up procedures |
The text of ISO standard has been approved as suitable for publication as an Indian Standard Without deviations. Certain conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:
a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and
b) Comma (,) has been used as a decimal marker while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
