Rather more depends what you have happening inside your product - the spread below is typical for most general electronics equipment to keep the electronics within semiconductor device working parameters (which will be higher than the ambient, so making delta T the consideration) without the need for too special considerations within the design such as fans and excessive heatsinks.
Safe temperatures for accessible surfaces are defined and may be a by-product consideration of your circuit heat dissipation where for instance you are using the chassis as a heatsink.

I find values of 35 up 45 degrees C and even higher. Is this defined in safety standards of certain product categories?
