French term or phrase: Durabilité de la résistance thermique
This is a phrase on a product data sheet. I get lots of Google hits for "durability of thermal resistance", but what worries me about that formulation is that practically all the hits are translations into English. I've tried googling "sustainability of thermal resistance" and various other forms of phrase, but don't get anything useful. What I am looking for is either confirmation that "durability of thermal resistance" is English rather than Franglais, or an alternative that one would see on a data sheet produced in Britain.

I am not interested in guesses, Google trawls (I can do that myself) or definitions cobbled together from nonspecialist dictionaries, only in informed answers from people familiar with the field.

Time constant of thermal resistance


Explanation:
To start the ball rolling....

Note that the opposite of thermal resistance is conductivity and of thermal impedance is diffusivity.

Also contrast 'thermal time constant'.

PS our UK school physics 'teacher' had, last millennium, written the standard school O- (GCSE), A-levels and 'Scottish Highers' physics textbook.

The lengthiness of the thermal or heat resistance had actually been my first thought, but didn't check out as well as the headlined answer.

Example sentence(s):
  • Rij is the steady-state thermal resistance and tij is the time constant of that thermal resistance rise from zero.
