How to define draft angle for texture on plastic part design?

Draft angle is import for plastic injected parts with texture. How to define it?

Refer to EDM texture VDI3400, there is a standard as picture below for reference. For chemical corroded textrue, can use Ra value to compare with EDM VDI3400.

It's better to add 1 more degree draft angle to standard for safety if possible.
