Common questions

What does ISO 17025 actually require from a forensic lab?+

ISO 17025 demands validated methods, trained personnel, documented procedures, and a functioning quality management system. Labs must prove their technical competence through method validation and staff qualifications, plus manage operations consistently through proper equipment calibration and internal audits.

Why do courts care about ISO 17025 accreditation?+

Accreditation signals that a lab meets international standards for competence and impartiality. Courts in most countries require it because it is the recognized benchmark for forensic laboratory credibility and reliable results.

Is ISO 17025 just about equipment and procedures?+

No. It covers both technical requirements like method validation, equipment calibration, and measurement uncertainty, plus management systems like document control, internal audits, and corrective actions. A lab needs both solid science and organized systems to pass.
