In Part 2, we go deeper into the science and real-world application of LED UV lash lamp safety.We break down the difference between accredited and non-accredited labs, explain what NIST traceability means in the context of testing, and take a closer look at what each IEC 62471 risk group actually represents outside of a technical report.Why do some lamps require shields, warnings, or black eye pads while others don’t? What would cause a lash lamp to fall into Risk Group 2 and does that automatically make it unsafe?This episode focuses on understanding hazard vs. real-world exposure, helping lash artists interpret classifications without fear or confusion.In Part 2, we discuss:Accredited labs vs. non-accredited testingNIST-traceable measurements explainedA deeper breakdown of IEC 62471 risk groupsReal-world examples of exposure scenariosWhy some lamps require additional protectionsAre Risk Group 2 lamps risky or just misunderstood?Our goal is to give you the knowledge to evaluate safety claims with confidence and clarity. https://www.intertek.com/blog/2024/09-17-photobiological-compliance-for-medical-devices/ https://webstore.iec.ch/en/publication/7076
