If the can holds EXACTLY 355 ml, with that many significant figures (3) this means that the contents can be between 354.5 ≤ n < 355.5 Any amount outside that range would be rounded off to either 354 or 356 ml (assuming scientific honesty on the part of the company). Without a precision tolerance specification (e.g. ±.2ml) that is the assumed precision. If the amount was specified as 355.0, then the presumed tolerance would be ±.05ml.

You could say that the volume inserted into each can must be within a particular tolerance range, e.g., 355ml +/- 1ml, or something like that. The machinery is set to allow such and such tolerance limits, and every nth can is selected and measured. (granted, this is a sort of post-hoc measurement--you want to make sure the tolerance limits are managed BEFORE there's a problem, such as 375 ml are deposited into the cans, causing them to overflow, spill onto the floor, and make a mess. And, of course, messing up your cans :) )
