What is a characteristic of Class 3 products?

Class 3 products are defined by their stringent requirements due to their applications in high-reliability environments, such as aerospace or medical devices. These products must meet critical performance standards to ensure that they function reliably under the most demanding conditions. This characteristic prioritizes the product's performance and longevity, making it essential that the assemblies operate without failure in severe situations.

The emphasis on critical performance standards is crucial because, in the case of failure, it may lead to significant consequences, such as safety hazards or high costs associated with downtime or equipment failure. This requirement distinguishes Class 3 products from those in lower classes, which may have more lenient standards regarding performance and reliability.
