when we are talking about film stocks like for EX--

NEW! ETERNA VIVID 500T inherits its saturated color,
high contrast and superior sharpness from the acclaimed
Eterna vivid 160.offering excellent matching with vivid 160,
this E.I 500 color negative film expands the parametres for shooting sharp.

what that EI stands for Emulsion intensity or not?

Exposure index.

From what I read on the internet, EI may refer to the sensitivity rating at which we have decided to expose the film, which may be different from the manufacturer's ISO rating.

The ASA/ISO standard for film speed is based on a procedure using a specified developer and a series of tests to determine a "correct" developing time. This then is used to find the actual speed of the film. Much of this does not apply to motion picture films AS THEY ARE USED.

The system also does not fit colour films very well..

SO the Manufacturers give an EI number which corresponds to the ASA/ISO Meter setting you would need to use to get what the maker considers optimum exposure.
