The classifications
• CI/SfB is the classification system most widely used by
architectural specifiers. The system has been in operation
for more than 30 years and is the industry standard.
• Uniclass is a UK classification system for structuring product
literature and project information, incorporating both
Common Arrangement of Work Sections (CAWS) and EPIC.
• EPIC is a European-wide classification system and should
be included especially if technical literature is to be used
on a pan-European basis.
