SW assembly drawing requirements

Good evening,
the question is quite simple.
I need to know what are the exactly requirements for assembly drawing in EU countries?
1. Views (front,right or left side, isometric)
2. Detail views of holes&shaft connections
3. Detail views of small parts
4. Ballons
5. Specification list
6. Some main dimensions like Lenght,Width just for showing the size of the assembly.
7. Have I to show tolerances of holes&shaft connections in detail views, or to write the Surface roughnace in the right upper corner? Or I need to write near the template table like a notice on the right down corner?
Can someone tell me the true rules of assembly?:) I'll really appreciate it!
Waiting for you, Engineers!:)

In an assembly drawing, you need to give all the details required for someone to assemble the parts (imagine you have all the parts on your bench. What would you need to know in order to put them together).

You should not have any information relating the the manufacture of the parts.

Use whatever views are required. One view may be sufficient. You could use an exploded view if you like. You could include a section view.

Balloon all the parts and have an items list (or BoM (Bill of Materials)). In solidWorks there will be automatic links between BoM item numbers and the balloon numbers.

The only dimensions you should include should relate to the positioning of parts at the assembly stage.

Include information relating to torque values for fasteners, thread retaining compound, lubricants etc.
