Bicycles Sectional Committee, TED 16
FOREWORD
This Indian Standard Third Revision) was adopted by Bureau of Indian Standards, after the draft finalized by the
Bicycles Sectional Committee had been approved by the Transport Engineering Division Council.
This standard was originally issued in 1955 and was subsequently revised in 1963 and 1993. Earlier requirements
of ladies bicycle frames were separately covered in IS 3404. Based on experience gained in the manufacture of
bicycle frames the revision
of
this standard has been taken up amalgamating both the standards covering the
requirements
of
all types
of
frames. With the publication
of
this standard IS 3404 : 1979 Specification for ladies
bicycle frames first revision) will be withdrawn.
The composition of the Committee responsible for the formulation of this standard is given in Annex A.
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 or analysis, shall be rounded off in accordance with
IS
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.
