NATIONAL FOREWORD
This Indian Standard which is identical with IS0 7930 : 1986 ‘Wheelchairs - Type classification
based on appearance characteristics’, issued by the International Organization for Standardi-
zation ( IS0 ) was adopted by the Bureau of Indian Standards on the recommendations of the
Artificial Limbs, Rehabilitation Appliances and Equipment for the Disabled Sectional Commtttee
MHD 10 ( 2291 ) and approval of the Medical Equipment and Hospital Planning Division
Council.
The text of IS0 standard has been approved as suitable for publication as Indian Standard
without deviations. Certain conventions are, however, not identical to those used in the Indian
Standards. Attention is particularly drawn to the following:
Wherever the words ‘International Standard’ appear referring to this standard, they should
be read as ‘Indian Standard’.
For the purpose of deciding whether a particular requirement of this standard is complied with,
the final value, observed or calculated, expressing the result of a test, shall be rounded off
in accordance with IS 2 : 1960 ‘Rules for rounding off numerical values (revised)‘. The number
of significant places retained in the rounded off value should be the same as that of the
specified value in this standard.
