What publication lists products that have received source approval?

The Qualified Products List (QPL) is the correct publication that specifically lists products which have received source approval. This list serves as a critical resource for engineers, contractors, and material suppliers as it ensures that only those products that have met the required specifications and testing criteria are used in construction projects.

The QPL acts as a guarantee to stakeholders that the approved products have undergone rigorous evaluation and meet the performance standards set by governing bodies like the Department of Transportation. This not only helps in maintaining quality in construction but also aids in streamlining the procurement process, as contractors can reference this list to identify which materials can be used without further testing.

In contrast, other options such as the Approved Materials List typically serve a broader function and might not focus solely on the source-approved status of the products. The Materials Inventory is more about the cataloging of available materials rather than certification. Lastly, Standard Specifications detail the requirements and standards for materials and practices but do not specifically provide a list of approved sources. Therefore, the Qualified Products List distinctly fulfills the necessary criteria for listing approved items.
