ISO/IEC 17025:2005 for Cannabis Testing Laboratories



In the interest of public health and safety, many states are raising the bar for cannabis testing laboratories by requiring those laboratories to be ISO/IEC 17025 accredited. This course will provide an introduction to ISO/IEC 17025 and its requirements for demonstrating technical competence of cannabis testing laboratories. Throughout this course, those involved in the cannabis industry will learn why this Standard applies to them and how accreditation improves their visibility and credibility over non-accredited labs. Attendees will be introduced to the A2LA accreditation process and will gain insight into the interpretation of the requirements of this international laboratory standard. Laboratory personnel will learn how implementing the Standard will make their labs better; regulatory personnel will understand how the Standard can ensure impartial technical competence. A2LA accreditation will deliver what you need: defensibility, credibility, sustainability, and accountability.
