Closed-Cell Thermal Insul...
1. SCOPE
1.1
This procedure defines the long-term thermal resistance (LTTR) of a foam
product as the value measured after 5-year storage in a laboratory environment
and provides means for its prediction based on an accelerated laboratory test.
1.2
This procedure, based on ASTM standard test methods C 1303 and C 518, can be
applied to a wide range of preformed as well as field applied…

Petroleum products — Estimation of net specific energy of aviation turbine fuels using hydrogen cont...
This International Standard describes a procedure for the estimation of the net specific energy of aviation turbine
fuels using hydrogen content data. It is not applicable to pure hydrocarbons.
The method is purely empirical and is applicable only to liquid hydrocarbon fuels derived by normal refining
processes from conventional crude oil which conform to the requirements of specifications for…
