Approved Methods
International standards exist to enable an interconnected world. By creating and adhering to standards, a global confidence is built. The international language of standards allows us to communicate our quality in a way any scientist can understand: with proven, reliable, and repeatable results. LECO is proud to take an active role in the development of and adherence to these international standards.
LECO instruments conform to the approved methodologies for many organizations.
