Quality management
• All DLQ labs are accredited according to
DIN EN ISO/IEC 17025.• All labs are certified according to ICAR CoQ.
• Proficiency tests
• Internal: automatically monitoring of routine testing by internal
reference material.
• National: periodic validation of results concerning all analyzed
components by participation in proficiency test.
• Single DLQ labs participate in international proficiency tests. By
taking part in national proficiency tests all labs benefit from
constructed network.
