Quality Training
NDT has strong in-house quality training
program. Continuous training is imparted to all the
staff in their respective fields to meet the growing
need of customers and international standards. Our
quality-training program is based on the principle of
continuous improvement.
Our staffs are trained in various disciplines and
special training is provided for specific projects, when
required.
QA/QC Area
For any test result to be valid and reliable, careful monitoring and implementation of QA/QC procedures are required. One key element of successful quality assurance is regular participation of a laboratory in a national and/or international Proficiency Testing Program (PTP) program. NDT International participates regularly in national and international PTP with most results exceeding the minimum requirements of acceptance.
