Wouldnt the test just need to apply to all modes? If its a matter of automatically tuning through a series of conditions then its reasonable that those could be documented and tested by the facility / standards body.

Sure, but emissions testing after you've got the car would be utterly useless.

  How so? Roadside emissions testing is very much a thing, as are annual emissions checks.

    Not in all states. I haven't had to do it in 20 years.

  The solution to this is to mandate that the car have built in emissions modelling. The car itself must keep track of how much Nox it has produced and how many miles it's driven. The ratio must stay below some legal limit (or you pay an extra pollution tax to go over it)

Efficiency testing of appliances (eg. Dishwashers) only tests the default mode. That's why all dishwashers have a mode which takes 4 hours and does a lousy job. It's the mode that only uses 3 drips of water and a sip of electricity.

  Do you have a link to any resource which talks about what the best way to use it? Everything easily searched seems to be how to get your dishwasher to run at its most efficient. I've never had a problem with our one with it's 2.5hr eco mode, when running overnight (which is 90% of our loads). If we need a quick load during the day, we'll use the 40min cycle. Either way the wash quality seems the same.

    I'm sure it varies widely by machine. Ours when on eco mode doesn't really dry the dishes (drying uses heat which uses electricity!), and only does one rinse to save water so dishes still have a bit of grime on them, especially if lots of the plates have thick gravy or anything on. I would put eco mode as 'passable', but you have to remember to scrape off the plates well beforehand, rince especially gungy stuff (like porridge), and to probably do a bit of hand drying of items afterwards. One the other hand, the 'intensive' mode only uses 50% more electricity, takes a quarter of the time, leaves the plates clean and dry every time, and uses a hotter wash temperature which I suspect is better at killing pathogens, and doesn't need any pre-rinsing or plate scraping beforehand. It's a no-brainer in my mind.
