NABL requirements for testing laboratories establish a framework for maintaining technical competence and delivering accurate testing results. Laboratories must comply with ISO/IEC 17025 standards by implementing quality management systems, maintaining calibrated instruments, validating test methods, training qualified personnel, ensuring environmental controls, documenting all activities, and performing internal audits and management reviews. Accreditation enhances laboratory reputation, improves operational efficiency, supports regulatory compliance, and increases acceptance of reports across domestic and global markets
