This International Standard specifies terminology for machines and equipment used in the building construction industry, for ease for reference and for use in discussions on standardization activities.

This International Standard refers to machines and equipment used on construction sites. They are divided into five groups:

• assembly of machines and components for installation and extraction of piles;
• equipment for preparing, conveying and compaction of concrete, mortar and processing reinforcement and formwork;
• machinery and equipment for aggregate processing;
• equipment for finishing work and maintenance;
• machinery and equipment for general use in construction processes.

The machinery and equipment presented in these particular groups are used primarily in building processes.

This International Standard does not include groups of building machines such as earth-moving machinery, cranes, lifting and access machinery.
