AVCP levels for construction products: What System 1+, 3 and 4 mean for your DoP

The AVCP system classifies construction products by testing responsibility. System 1+ requires full notified body oversight, System 3 splits tasks between manufacturer and lab, and System 4 is self-declaration. Understanding which applies to your product determines your Declaration of Performance compliance path.
