Testing and inspection are essential processes used to ensure the quality and safety of products, systems, or structures. Testing involves evaluating a product's performance under specific conditions, while inspection focuses on examining it for defects or compliance with standards. Both processes help identify issues before a product reaches consumers. These practices are commonly applied in various industries, including manufacturing, construction, and healthcare. For example, building codes require regular inspections to ensure structures are safe, while medical devices undergo rigorous testing to meet regulatory standards. Together, testing and inspection help maintain high-quality standards and protect public safety.
