The IEC offers several definitions of thermal equilibrium in
its Glossary.
thermal equilibrium conditions
stable temperature conditions indicated by temperature
changes of no more than 3 K (5 °F) or 1 % of the absolute
operating temperature, whichever is higher between two
readings 15 min
Luminaires 60598 has 1 degree per hour, just to add another variant.

Nice to see a harmonised approach from the various IEC TCs
The 60034 definition might be taken as more 'horizontal' (i.e. a
reference definition that other committees should adopt) than the
