Two documents, two issuers
Playground equipment documentation includes two similarly named but differently weighted documents. A certificate of conformity is issued by an independent certification body, typically accredited to EN ISO/IEC 17065, after assessing the product against the requirements of EN 1176. A declaration of conformity is issued by the manufacturer itself, and under its own responsibility confirms that the delivered equipment matches the certified type and stated requirements. In conformity assessment terminology, the first is third-party verification and the second is first-party verification. The declaration accompanies the certificate and ties it to a specific delivery, but it does not replace it.
What to request and how to check it
A public sector client should request both documents. For the certificate, check which body issued it, whether that body is accredited for product certification, whether the certificate covers the exact product and configuration quoted, and whether it is still valid, since certificates carry an expiry date and are tied to a specific product version. For the declaration of conformity, check that it clearly names the equipment being supplied, references the correct version of the standard, and relates to the actual project rather than a generic template. If anything on this list is unclear, it is reasonable to request clarification directly from the manufacturer before proceeding.
A note on generic versus project-specific documents
Not all documents are prepared to the same level of specificity, and this varies between manufacturers and markets. Some documents are prepared per project and named line item, while others are more generic. Neither approach is inherently wrong, but it helps a public sector client to understand which type of document they are looking at, since a document that clearly names the project and the equipment is generally easier to defend during an audit or inspection than one that reads as a generic template. Requirements can vary by country and by the specific circumstances of the tender, so where there is any doubt it is worth confirming expectations with legal or procurement advisers. Where Croatian tender documentation requires conformity with HRN EN 1176, the contracting authority may require that conformity be proven through a certificate from an accredited body, and a bidder without a certificate is required to prove conformity by other appropriate means under the conditions set out in Article 213 of the Croatian Public Procurement Act.
