* BS 15000 for IT Service Management, ( ITIL ), now ISO / IEC 20000

Such standards include DIN, BS, and / or ISO standards.

BS and ISO produce standards to show recommended practices but it is up to individuals to produce the drawings.

Examples include the ISO / IEC 17799 ( Or more properly BS 7799-1, which is now ISO / IEC 27002 ) or the German IT-Grundschutzhandbuch.

All testing laboratories must comply with ISO 17025, and certification bodies will normally be approved against either ISO / IEC Guide 65 or BS EN 45011.
