Harmonized standards

This section contains all important information about Serbian standards representing the adoptions of European harmonized standards in the field of electromagnetic compatibility.

Serbian standards for electromagnetic compatibility are standards representing the adoptions of European harmonized standards under the Directive onElectromagnetic Compatibility (EMC).

Serbian standards in this field, as well as all other fields in Serbia, are adopted by the Institute for Standardization of Serbia (ISS). The list of Serbian standards in the field of electromagnetic compatibility representing the adoptions of European harmonized standards (hEN) is under the jurisdiction of the Ministry of Economy of the Republic of Serbia. The latest updated list of Serbian standards for electromagnetic compatibility was published in the „Official Gazette of the Republic of Serbia“, No. 37/19, of 31 May, 2019. See: List of Serbian standards for EMC.pdf (privreda.gov.rs)

Application of standards from the List of Serbian Standards in the field of electromagnetic compatibility

If the equipment meets the requirements of Serbian standards or parts thereof, which represent the adoptions of the corresponding harmonized standards or parts thereof, and for which a list of standards is compiled and published in accordance with the law on the basis of which technical requirements for products and conformity assessment are regulated, in that case the equipment also meets the essential requirements of this Rulebook that are covered by those standards or parts thereof.

The manufacturer may design and manufacture electrical equipment without applying any of the standards from the list, or by applying only parts of a standard. It is also possible that there are no Serbian standards for a particular electrical equipment. In this case, the manufacturer must demonstrate through technical documentation that his technical solution fully meets all the essential safety requirements prescribed by the Rulebook within the framework of other technical specifications.

In conclusion, the use of Serbian standards from the list of standards is the simplest and fastest tool in the process of demonstrating product compliance with the essential requirements.

2.Harmonized standard (hEN) – The Regulation (EU) No 1025/2012 on European standardization defines hEN as „a European standard adopted at the request of the European Commission for implementation within the framework of harmonised legislation of the European Union“. These harmonized European standards hEN within the framework of the EMC, whose reference is cited in the Official Journal of the European Union (OJEU), provide a presumption of conformity for products conforming to such European standards. According to the summary list from September 2022, there are around 170 harmonized standards (hEN) under the Electromagnetic Compatibility (EMC) Directive. Some of these harmonized standards (hEN) were initiated and developed within the European Technical Committee CLC/TC 210, Electromagnetic Compatibility, however, most are the result of its cooperation with IEC/TC 77, Electromagnetic Compatibility, and the International Special Committee on Radio Interference (CISPR).

The application of harmonized standards is VOLUNTARY. Manufacturers have the option to choose any technical solution that ensures compliance with the essential requirements laid down in the directives. This is a very important clause as it guarantees the basis for technical development, which is the key when manufacturers of new or innovative products for which there are no standards yet want to certify their products in accordance with the legal European framework.

In accordance with the Guidance on the Application of EMCD (2014/30/EU Directive) from 2018-12-19, the selection of relevant harmonized standards (hEN) under the EMC Directive is the responsibility of the manufacturer. When the manufacturer decides to apply harmonized standards (hEN), he or she will, according to this guidance, select them according to the following order of priority:

– standards specific for the product in question (if available);

– familiy of standards for the product in question (if available);

– generic standards.

The first two groups of standards for a product take into account the environment, operating conditions, and loads of the equipment, and are considered to be the best for demonstrating compliance with the EMC Directive.

Generic standards can be used if there are no standards specific for the product in question or familiy of standards for the product in question. They are divided into generic environments, but do not contain specific guidelines on how to handle and load equipment during the testing phase of EMC assessment.

Very often it is necessary to apply several harmonized standards (hEN) in order to cover all the essential requirements of the Directive. Each hEN identifies the essential requirements that are given in the Annex to the standard.

Main aspects that generally need to be covered are the following:

Radiated disturbances;
Conducted disturbances at mains and telecommunication ports;
Immunity to continuous radiated and conducted disturbances, and
Immunity to transient phenomena.

The application of multiple standards may be necessary to address all relevant phenomena across all relevant frequency ranges. For multi-purpose devices, it may also be necessary to select standards relevant to all primary functions.

Useful practical information on selecting appropriate CENELEC standards can be found in CENELEC Guide 25, Use of EMC standards for the application of the EMCD, available on the CENELEC website. CENELEC Guide 24 is also available on the same website and it explains the general structure of EMC standardization, as well as the corresponding roles of EMC standards, e.g., basic standards, generic standards, and standards specific for the product in question and familiy of standards for the product in question.

Harmonized standards (hEN) are developed in the same way as any other European standard (EN) in CENELEC, but with additional notes, i.e.:

– All harmonized standards must include an informative Annex ZZ (CENELEC), which shows the relationship between the clauses of the standard and the requirements of the legislation (this is mandatory for hEN);

– The withdrawal date from the Official Journal of the EU (OJEU) has no connection with the date of withdrawal (DOW) mentioned in the preface of the hEN standard being replaced, i.e., (DOW) represents the deadline by which national standards that are in conflict with the published European standard must be withdrawn, while the withdrawal date from the OJEU represents the date on which the presumption of conformity ceases, i.e.

there is no automatic compliance between the two withdrawal dates.

Specificities of hEN standards under EMC

Annex ZA – For the standards developed within Frankfurt agreement, the dated and updated normative references must be clearly identified in Annex ZA.

Annex ZZ – For the users of Serbian standards representing the adoptions of hEN this Annex is important because because based on it, the clauses/subclauses of the standard are identified that correspond to the essential requirements of the Rulebook, that is, the EMC Directive.

In the event that one hEN covers different EU directives/regulations, separate Annexes ZZ must be prepared.

Risk analysis and risk assessment – Conformity assessment procedures for equipment require the manufacturer to provide technical documentation. This documentation allows for the assessment of the equipment's compliance with the relevant requirements and must include an adequate risk analysis and assessment. hEN requirements are expected to be met when the equipment is tested according to the specification given in the standard. Based on the risk analysis and if the applied harmonized standard does not cover all phenomena related to the equipment, the manufacturer is required to consider all remaining risks not covered by the harmonized standards (hEN) in order to consider all phenomena. The EMC risk concept refers to risks related to the electromagnetic compatibility protection objectives, which are listed in Annex 1, „Essential Requirements“. Based on the knowledge of the relevant EMC phenomena related to the equipment and its operating environments, an EMC assessment can be performed.
