BS EN 81346-2:2009 Industrial systems, installations and equipment and industrial products - Structuring principles and reference designations - Classification of objects and codes for classes
This part of International Standard 81346, published jointly by IEC and ISO defines classes and subclasses of objects based on a purpose- or task-related view of the objects, together with their associated letter codes to be used in reference designations.
The classification is applicable for objects in all technical areas, e.g. electrical, mechanical
and civil engineering as well as all branches of industry, e.g. energy, chemical industry, building technology, shipbuilding and marine technology, and can be used by all technical disciplines in any design process.
