To cite an organisation correctly in IEEE style My tex based on Espanta's answer

@techreport{AAMI,
    title = {Recommended Practice for Testing and Reporting Performance Results of Ventricular Arrhythmia Detection Algorithms},
    institution = {{Association for the Advancement of Medical Instrumentation}},
    year = {1987},
    address = {Arlington, VA, USA}
}


which is shown correctly now after Espanta's answer in Bibliography.
However, the thing is shown in my text similarly as before :



where AAM (1987) is shown. 
I do not know what I should have in the text body for this citation, since the citation does not have author but institution.
I think AAMI (1987) is good.

What is the correct way of citing this organisation in IEEE style?
I think what you are referring to is a technical report or white paper from certain company. Then it should not be misc type. I think if you change your item from misc to technical report, the IEEE style in latex will handle it. 

The correct field in citation style should be
Authors(if any), title, publisher, address, year.
