Preamble
"As a Member of the International Association of Forensic and Security Metrology, I pledge not to prejudge or present biased results when documenting a crime scene, event, major disaster, terrorist event, violent crime, etc. I will do my best to remain fair and impartial, searching to represent and present the truth in all that I perform. Any opinion rendered based on any analysis that I may be required to perform will be based on the physical evidence and facts discovered in any given case. I further pledge to render an opinion only within my field of competence, to maintain an attitude of independence, impartiality and calm objectivity in order to avoid personal or professional involvement in the proceedings, to constantly seek to improve my professional capabilities by experimentation and study, and to improve the standards, techniques and practices in the field of metrology by making the benefits of my professional attainments available to all other association members."
