If you standardise something that was not standardised before you are bringing multiple things that were different and making them similar, that is literally the definition of homogenisation. Both represent an effort to “become more similar”, standardisation is usually just used exclusively for sets of rules and guidelines.
So if you are standardising a set of bursts that were not standardised you are in effect homogenising them. Playing around with synonyms to go “standardisation is when they do x homogenisation is when they do y” to make it sound like it’s not homogenisation is just poor sophistry
