Quality control
Tochigi Works and its overseas affiliates
have
acquired International Standard Quality Management
System ISO9001 and ISO14001 authorisation. The Tochigi
Works performs thorough product quality control using
various environmental tests. Hitachi Room Air Conditioning
Indoor and Outdoor units are manufactured according to
this ISO certification system.
Hitachi products all carry the necessary ‘CE’
declaration markings,
and also feature in the extensive
Eurovent Listing programme. Listing in the Eurovent
directory helps ensure peace of mind for the installer and
the end user, as it certifies the important operating
parameters and performance of the units.
