Which term describes the conditions under which a product is approved for use?

• A. Manufacturer's Instructions
• B. Compatibility Testing
• C. Listing Limitations
• D. ASME B16.4

Answer: (C)

The conditions under which a product is approved for use are described by its listing limitations. When a product is tested and listed by a recognized testing laboratory, the listing not only confirms that the product is suitable for certain applications, but also specifies the exact constraints—such as compatible system components, installation methods, environmental and pressure limits, and other restrictions. Using the product outside those listed conditions means it isn’t approved for use in that scenario. Manufacturer's Instructions cover installation steps, compatibility testing is about determining compatibility, and ASME B16.4 is a standard for fittings; none describe the approved-use restrictions the way listing limitations do.
