[Grammar] Till/until + (?)

[Jack8rkin]

Hello!
Will it be grammatical to say "Tests will be conducted till (until) the maximum pressure and temperature" or the predicate "are reached" (or a synonymous one) is required at the end of the phrase?

Thanks in advance.

I don't know if it is grammatically incorrect to omit "are reached", but it would sound better if you added it, I think.

You have to add either a date or an event after "until".
- until tomorrow (date)
- until my sister graduates (event)

If you just wrote "until the maximum temperature", it would be kind of like I only wrote "until my sister". Even though, people can understand what your sentence means from the context...

Edit: I forgot to specify that I'm not a teacher... Perhaps someone will disagree.
