What is a standard?
Standard is a document, established by consensus and approved by a recognized body, that provides, for common and repeated use, rules, guidelines or characteristics for activities or their results, aimed at the achievement of the optimum degree of order in a given context. Standards are based on the consolidated results of science, technology and experience.
What is a Croatian standard?
Croatian standard is any standard adopted in the Croatian Standards Institute and implemented in the Republic of Croatia.
What is the difference between standards and documents other than standards?
Documents other than standards are for example technical specifications, codes of practice, guides, recommendations, guidelines, reports, technical agreements, etc.
An essential difference between standards and technical specifications and other documents is the level of consensus needed for their adoption.
Standards and technical specifications contain provisions that have to be fulfilled by a product, process or service (normative elements), while the other types of documents contain only informative elements.
In what formats are standards available?
Croatian standards and other normative documents (HRN, HRS, HRI) and International Standards (ISO and IEC) are available in hardcopy and in electronic (pdf) format.
Other standards distributed by the Croatian Standards Institute are available only in hardcopy. Normative documents purchased in electronic form are delivered on CD-ROM.
