What does it mean if equipment or products are described as 'labeled'?

When equipment or products are described as 'labeled', it indicates that they have undergone testing and evaluation by an approved laboratory and have met specific safety and performance standards. This labeling serves as a formal certification that the product has been assessed for compliance with established criteria, ensuring it is safe for use in various applications.

Being 'labeled' is significant in the context of building codes and regulations, such as the International Mechanical Code, because it provides assurance to users, inspectors, and code officials that the product has been standardized and verified to perform safely under intended conditions.

The other concepts related to user instructions, warranties, and identification may be beneficial features of a product, but they do not determine its status as 'labeled' in a regulatory context. Thus, the correct understanding relies on the recognition of the rigorous testing and certification that falls under the umbrella of labeled equipment or products.
