Official reference doesn't include author I want to cite an IEEE norm in a document. They provide several way to cite it on their website and in particular bibTeX. This is perfect because I use LaTeX.

However, the citation does not contain any author field. This raise a warning.

Should I keep this warning or modify the entry to avoid it? And in this case, what should I enter as author?

Link to the norm page. In abstract, go to download citation. 

For example bibTeX citation only:

 @ARTICLE{4610935,
journal={IEEE Std 754-2008},
title={IEEE Standard for Floating-Point Arithmetic},
year={2008},
pages={1-70},
keywords={IEEE standards;floating point arithmetic;programming;IEEE standard;arithmetic formats;computer programming;decimal floating-point arithmetic;754-2008;NaN;arithmetic;binary;computer;decimal;exponent;floating-point;format;interchange;number;rounding;significand;subnormal},
doi={10.1109/IEEESTD.2008.4610935},
month={Aug},}
In my experience, the bibtex entries provided by many publishers are often quite bad, and IEEE is one of the worst offenders here. So it is quite common that one has to edit them before they become usable.

For this specific entry, the type "article" is clearly wrong, and the root of the problem.
