Construction Products AVCP Systems 1+, 1, 2+, 3 and 4
AVCP systems allocate construction-product assessment tasks between the manufacturer and third parties.
Continue with the relevant decision step
Direct answer
AVCP systems allocate construction-product assessment tasks between the manufacturer and third parties. Under the applicable earlier CPR route, 1+, 1, 2+, 3 and 4 differ in product certification, FPC certification or laboratory involvement; the number is not a performance grade.
Decision and evidence
Identify the product's technical reference, intended use and transition status before selecting tasks. Keep the manufacturer's performance declaration and production controls in every route.
Technical basis
For construction products, the harmonised specification or ETA and intended use determine AVCP 1+, 1, 2+, 3 or 4. The number is a division of tasks, not a quality grade.

Does System 1 mean a better-quality product than System 4?
Numbers describe allocation of assessment tasks, not performance classes. The technical basis and intended use determine the applicable system. Duties cannot be changed simply to reduce cost. Keep performance values distinct from the assessment system in quotations and declarations.
Can new CPR systems immediately be applied to every existing product?
Identify the product's technical basis and transitional provisions first. New systems do not automatically transfer to all products continuing under earlier references. Review new environmental assessment tasks under their applicable conditions. Do not construct a private route by mixing parts of old and new frameworks.
