Aggregate CE workflow: resolve scope before declaring
Aggregate CE workflow: resolve scope before declaring. Evidence, a conditional example and responsibility boundaries for this preparation purpose.
Scope and decision inputs
Start with the supplied material, concrete or asphalt use, natural/recycled source, fractions and production sites; identify the actual cited specification.
Determine the applicable assessment system and evidence gaps before commissioning tests or promising a certificate date; CPR transition is product-family specific.
Conditional case and response
Hypothetical application adds recycled feed to a natural aggregate but keeps the old commercial size and declaration unchanged.
Compare changed composition and processing with existing evidence. Agree necessary evaluation and controls instead of treating the unchanged name as proof of coverage.
Evidence outputs and responsible parties
Complete required testing and control work, obtain applicable external outputs and align the declaration and CE information with the evidenced product scope.
The manufacturer implements and declares. Kayra coordinates agreed preparation; external assessment decisions remain with the responsible laboratory or notified body.

Aggregate CE workflow: resolve scope before declaring — Send the actual source, fraction, site, use and existing records to discuss the preparation outputs; external decisions remain with the responsible parties.
