The OP asked when you're governed by your aircraft category. I would argue from the IAF, based on the table below (which is ICAO PANS-OPS). Will it work to fly
most approaches faster? Most likely, they aren't edge cases.
Your posted documentation clearly reads ‘range of speeds’.
Which means you can be well above your max category speed at the IAF and still be at the correct threshold speed for your category.
So no, speed at IAF does not apply
Now if a non normal condition increases your Vref then you need to apply the higher category minimums if applicable.
Could also mean you’re no longer legal to fly that approach if it’s a A/B only.
