Disclosure to Promote the Right To Information
Whereas the Parliament of India has set out to provide a practical regime of right to
information for citizens to secure access to information under the control of public authorities,
in order to promote transparency and accountability in the working of every public authority,
and whereas the attached publication of the Bureau of Indian Standards is of particular interest
to the public, particularly disadvantaged communities and those engaged in the pursuit of
education and knowledge, the attached public safety standard is made available to promote the
timely dissemination of this information in an accurate manner to the public.

FOREWORD
This Indian Standard was adopted by the Bureau of Indian Standards after the draft finalized by the Lubricants
and Related Products Sectional Committee had been approved by the Petroleum, Coal and Related Products
Division Council.
In a closed heat transfer system, the thermic fluid is used as a media for indirect heating purposes. This fluid is
circulated by means of a pump from heater to the equipment to be heated and back to the heater. Normally, the
system contains an expansion tank in which the oil is exposed to the environment. In a properly designed system,
the oxidation of thermic fluid is negligible. The main cause of oil deterioration is thermal degradation (cracking)
at high temperatures, the first sign of which is a drop in flash point. If thermic fluid temperature is allowed to
rise unduly in the heater, carbon deposits will form on the heater surfaces. To avoid an undue temperature rise,
thermic fluid should flow reasonably fast through the heater, and the flow should be turbulent.
It is important that thermic fluid viscosity should be low, particularly during start up, to avoid long residence
time of the oil in the heater and the consequent possibility of thermal degradation. The volatility of the thermic
fluid should be low to ensure the formation of vapour is minimized during normal operation. Hence the
specification of a thermic fluid which can enable the user to select an appropriate grade for the given purpose
is very important.
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
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.
