Materials Certifications and
Tests
Ariel's compressor components
are purchased and machined in large quantities, often in lot quantities.
Raw materials
suppliers are audited for their quality control and performance. These
suppliers provide certain lot sample testing to verify materials chemical
compositions and / or physical properties. With
the large quantity of components purchased each year Ariel does not require
these materials certifications, but rely on the suppliers quality control
system and the auditing process. This
system maintains supplier quality while limiting component costs and coordination.
An Inspection
and Test Plan has been prepared to show what Ariel and Ariel's suppliers
provide for materials certifications. This
list includes those tests listed as optional in the Ariel Price Book.
Additional
testing requests must be reviewed and approved by Ariel.
