What is a key takeaway regarding ASTM specifications?

Explanation:
ASTM specifications define the minimum material properties and the tests used to verify those properties. They don’t guarantee how the product will perform in service, because real-world performance depends on many other factors—design, installation workmanship, substrate preparation, climate, aging, and ongoing maintenance. In roofing, a membrane or coating can meet its specified numbers yet still fail if installation details (like fastener pattern or adhesive application) are mishandled or the system isn’t designed to handle expected loads and movement. So the main takeaway is that the spec sets the baseline properties the material must meet, but performance in the field isn’t guaranteed by the specification alone.
