Comprehensive Guide to Dermatological Sensitivity Testing Laboratory Testing Service Provided by Eurolab

Standard-Related Information

Dermatological Sensitivity Testing is a critical aspect of ensuring product safety and reliability, particularly in industries where skin contact or exposure is inevitable. The relevant standards governing this testing service are outlined below.

International Standards

  • ISO 10993-1:2018 (Biological evaluation of medical devices Part 1: Evaluation and risk management framework)
  • ASTM E2859-17 (Standard Guide for Selecting Test Methods to Evaluate the Cytotoxicity of Materials in Cell Culture)
  • EN ISO 10993-5:2017 (Biological evaluation of medical devices Part 5: Tests for in vitro cytotoxicity)
  • TSE LRTS 1061:2020 (Dermatological and sensitivity testing methods)
  • Standard Development Organizations

    The International Organization for Standardization (ISO), American Society for Testing and Materials (ASTM), and European Committee for Standardization (CEN) are prominent standard development organizations that contribute to the development of standards governing dermatological sensitivity testing.

    Standard Evolution and Update

    Standards evolve through a rigorous process involving stakeholder engagement, expert input, and review by technical committees. Updates ensure that standards remain relevant and effective in addressing emerging challenges and advancements in technology.

    Industry-Specific Compliance Requirements

    Dermatological sensitivity testing is essential for industries such as cosmetics, pharmaceuticals, medical devices, and textiles, where skin contact or exposure can occur. Manufacturers must comply with applicable standards to ensure product safety and reliability.
