To maintain accreditation, regular audits are performed to verify strict compliance with all industry-accepted standards. These audits cover various operational areas, including—but not limited to—the laboratory facility, equipment, staff training and expertise, quality control procedures, and financial accountability. Independent test facilities without NAIL accreditation are not subject to monitoring to ensure adherence to industry best practices and standards.

LTL is home to Canada’s largest NAIL-accredited testing facilities.
