ISO standard for engineering drawings

When Freelance drafter begin to make a drawing in AutoCAD, there are habits that are less appropriate for beginners. Freelancer immediately draw without any layer. Though the layer is very important for the regulation of each object image. Freelance drafter only need to create a single master file with a standard layer, save it and if freelance drafter want to create a new project to stay Save As .. 
What layer in accordance with ISO standards?Freelance drafter can give layer name  with any name, which is important for your own informative. Referring to the freelance drafting technique  when I had a separate list. Please if freelancer want to follow.
1.  Layer outline, with the type of line CONTINUOUS, 0.5mm thick lines [used to outline objects / object].
2. Layer CENTER, CENTER lines of type, 0.3mm thick lines [used to outline objects flashlight].
3. Layer Hatch, with CONTINUOUS line type, line thickness 0.2mm [used for shading line].
4. Layer HIDDEN, HIDDEN line with the type, 0.2mm thick lines [used to describe a hidden line outline].
