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…

Information technology — Mixed Raster Content (MRC)
This Recommendation defines a means to efficiently represent raster-oriented pages that contain a
mixture of multi-level and bi-level images. Any of the many ITU-T recommended encoding schemes,
such as T.81 (JPEG) for the encoding of multi-level images and T.6 (MMR) for the encoding of bi-level
images, may be combined within the context of this Recommendation. Similarly, ITU-T spatial and
colour…
