Is there a standard for job sectors?

Is there any sort of recognised standard for grouping jobs into job sectors e.g. 'technology', 'emergency services'? I'm looking to use this in a program I'm working on.

Closest I can find is this, but I want to know if there's an official standard.

Solution

There is an international standard for job classifications, but not by ISO, it's by the International Labour Organization

Also, https://en.wikipedia.org/wiki/International_Standard_Classification_of_Occupations
