What do testing laboratories primarily assess regarding products?

Testing laboratories primarily assess products for their conformance to applicable safety standards. This is a critical function because ensuring that a product meets established safety regulations protects consumers from potential hazards and risks associated with the product's use. Testing laboratories conduct various evaluations and tests to determine whether a product adheres to safety criteria set forth by regulatory bodies, which may include electrical safety, fire hazards, and environmental impacts.

While other factors like durability, market demand, and cost efficiency are important aspects in the overall lifecycle of a product, they are not the primary focus of testing laboratories. These labs are specifically tasked with verifying that products are safe for consumer use, which is essential for maintaining public trust and compliance with legal requirements.
