ISO 4120 (standard)

ISO 4120 is an international standard that provides a systematic way to evaluate the effectiveness of animal repellents. It ensures that tests are fair, repeatable, and comparable by defining procedures, testing conditions, and measurement methods. This helps manufacturers and researchers determine whether an animal repellent performs as intended, such as deterring pests from crops or protected areas. Essentially, ISO 4120 creates consistent guidelines to assess how well repellents work, aiding in their development, approval, and use to ensure they are both effective and safe.
