What is a harmonized standard?
A harmonised standard is a European standard elaborated on the basis of a request from the European Commission to a recognised European Standards Organization (CEN, CENELEC or ETSI) to develop a European standard that provides solutions for compliance with the relevant European Union harmonization legislation. The European Commission is responsible for publishing the references and titles of harmonized standards and references to them in the relevant European Union harmonization legislation. Manufacturers, other economic operators or conformity assessment bodies can use harmonised standards to demonstrate that their products, services or processes comply with the relevant EU legislation. References of harmonized standards are available on the European Commission's website. The purpose of that website is to provide access to the latest lists of references of harmonized standards published in the Official Journal of the European Union (OJEU).
What is an ICS code?
The International Classification for Standards (ICS) is a convention managed by the International Organization for Standardization (ISO) and used in catalogues of international, regional and national standards and other normative documents. ICS is a hierarchical classification which consists of three levels (fields, groups and sub-groups). A standard covering e.g. more than one sub-group is classified in all of these sub-groups. ICS ensures language-independent global communication. ICS is regularly updated. The current version is its Seventh edition published in 2015.
Is certification part of HZN activities?
No. HZN does not perform the assessment of conformity of products, processes and services to Croatian standards and does not issue conformity assessment certificates. These activities are performed by conformity assessment bodies.  A list of certified conformity assessment bodies in the Republic of Croatia is available on the website of the Croatian Accreditation Agency (HAA) in the section Accredited bodies.
