In the following sentence, how should the clause of purpose be introduced?

Both are correct:

"Interventions that may be required to meet minimum safety standards."

"Interventions that may be required for meeting minimum safety standards"

  • Sarah went to the computer lab to print out her research report.
  • This function on the air conditioner is for reducing humidity.

Clauses of purpose are usually introduced by

  • "to" + infinitive
  • "in order to" + infinitive
  • "in order that"
  • "so as (not) to" + infinitive
  • "so that" + an auxiliary verb (can, could, will, would...)
  • "in case" + present simple
  • "for" + noun
  • "for" + "-ing"
  • "with a view to", "for the purpose of", "with the intention of" + "-ing"
  • "prevent + noun/pronoun + from + "-ing". (negative purpose)

  • Do both of them have exactly the same meaning?

  • @Robbo They may have exactly the same meaning depending on context. "required to meet" can be ambiguous ("interventions that will have to be used x interventions that will have to be improved) To avoid ambiguity (if context isn't clear enough) you can use "in order to": "Interventions that may be required in order to meet minimum safety standards."

    There’s also the for him to verb construct, which John Lawler calls the for-to complementizer. In spirit but not in form this works a bit like Portuguese personal infinitives, which are inflected for person but not tense, and which can serve as the object of a preposition.
