National and international standards (governing sizes and performance)
guarantee interchangeability and homogeneity in industrial applications
of castors and wheels. The most important body for setting standards
at the international level is ISO (International Standard Organisation),
which includes representatives of all the technologically advanced
nations. Italy participates in ISO meetings through UNI (the Italian
Certification Organisation). A special technical committee, ISO/TC
110, has set up a subcommission, SC3, specifically entrusted with the
standardisation of wheels and castors on trolleys used for internal
transport. AVO is a member of the Italian Union of Manufacturers of
Wheels and Castors UCIR; this group is in contact with the corresponding
groups in the 4th section of FEM (Federation Europeenne de la
Manutention), to which the European Union’s major manufacturers
of lifting and transport equipment all belong. The Italian Union of
Manufacturers of Wheels and Castors UCIR, is an active participant
in studies regarding the issuing of Europe-wide standards, to be the
subject of a study by a subcommission of the CEN (European Standards
Committee).
