Are users and distributors entitled to see a product’s technical documentation?
No. Only market surveillance authorities and conformity assessment bodies have the right to see technical documentation.
Market surveillance authorities are consumer protection, trading standards and health and safety authorities. Conformity Assessment Bodies approve and certify higher-risk products. They include EU Notified Bodies and UK (Market) Conformity Assessment Bodies (UKMCAB or UKCAB) also known as Approved or Appointed Bodies (could divide this up into more questions: What is a NB/CAB? etc.)
