The outer packaging must be tested with multiple types of what?

• A. Inner packaging
• B. Outer packaging materials
• C. Liquid samples
• D. Temperature conditions

Answer: (A)

Testing the outer packaging with multiple inner packaging types ensures the whole package will perform safely across different contents. The inner packaging is what actually holds the product, and its interaction with the outer container can affect leakage, cushioning, and containment. By using several inner packaging types during testing, you confirm the outer packaging design provides reliable protection no matter which inner container is used. Other options focus on different aspects—outer materials, liquids, or temperature—which are addressed in separate tests, not this specific requirement.
