Foreword This Technical Report (TR) has been produced by Technical Committee Electromagnetic compatibility and Radio spectrum Matters (ERM). The present document is part 1 of a multi-part deliverable covering the guide to the application of harmonized standards to multi-radio and combined radio and non-radio equipment, as identified below: Part 1: Part 2: "ElectroMagnetic Compatibility"; "Efficient use of the radio spectrum". Introduction The following text is taken from the Harmonized Standard Pro-forma and is included here to provide the reader with an overview of harmonized standards and their relationship with the R&TTE Directive [1]. Harmonized standards produced by for use under the R&TTE Directive [1] are designed to fit in a modular structure to cover all radio and telecommunications terminal equipment under the R&TTE Directive [1]. Each standard is a module in the structure. The modular structure is shown in figure 1.

For article 3.3 various horizontal boxes are shown. Dotted lines indicate that at the time of publication of the present document essential requirements in these areas have to be adopted by the Commission. If such essential requirements are adopted, and as far and as long as they are applicable, they will justify individual standards whose scope is likely to be specified by function or interface type. The vertical boxes show the standards under article 3.2 for the use of the radio spectrum by radio equipment. The scopes of these standards are specified either by frequency (normally in the case where frequency bands are harmonized) or by radio equipment type.
7 7 TR V1.1.1 ( ) For article 3.1b the diagram shows , the multi-part product EMC standard for radio used under the EMC Directive [2]. For article 3.1a the diagram shows the existing safety standards currently used under the LV Directive [3] and new standards covering human exposure to electromagnetic fields. New standards covering acoustic safety may also be required. The bottom of the figure shows the relationship of the standards to radio equipment and telecommunications terminal equipment. A particular equipment may be radio equipment, telecommunications terminal equipment or both. A radio spectrum standard will apply if it is radio equipment. An article 3.3 standard will apply as well only if the relevant essential requirement under the R&TTE Directive [1] is adopted by the Commission and if the equipment in question is covered by the scope of the corresponding standard. Thus, depending on the nature of the equipment, the essential requirements under the R&TTE Directive [1] may be covered in a set of standards. The modularity principle has been taken because: - it minimizes the number of standards needed. Because equipment may, in fact, have multiple interfaces and functions it is not practicable to produce a single standard for each possible combination of functions that may occur in an equipment; - it provides scope for standards to be added: - under article 3.2 when new frequency bands are agreed; or - under article 3.3 should the Commission take the necessary decisions without requiring alteration of standards that are already published; - it clarifies, simplifies and promotes the usage of Harmonized Standards as the relevant means of conformity assessment.
8 8 TR V1.1.1 ( ) 1 Scope The present document provides guidance in assessing the technical difficulties with the application of harmonized EMC standards to combined products, which include a radio and/or a telecommunication function. Examples to be covered include products containing multiple radio technologies, radio in IT equipment, radio in domestic equipment, etc. The present document is intended to cover these combined products, which are subject to the provisions of the R&TTE Directive [1] as a result of this combination. The purpose of the present document is: - to provide guidance with the testing of this type of equipment, - to eliminate duplicate testing wherever possible, - to recommend the selection of appropriate performance assessment and performance criteria for this type of equipment, - to provide guidance for conformance evaluation and market surveillance. Part 2 of the present document provides guidance on the application of harmonized radio product standards for combined products under article 3.2 (effective use of spectrum) of the R&TTE Directive [1]. The present document does not cover: - single custom built products that are tailored to a specific customer quotation, - product that operate independently if they are not contained within a single enclosure. 2 References For the purposes of this Technical Report (TR) the following references apply: [1] Directive 1999/5/EC of the European Parliament and of the Council of 9 March 1999 on radio equipment and telecommunications terminal equipment and the mutual recognition of their conformity (R&TTE Directive).

Figures 3 to 9 illustrate the various product combinations considered in the present document Scenario 1 Product A Product A is placed on the market in accordance with the relevant EU directive(s). Product B Product B is placed on the market in accordance with the relevant EU directive(s). Product Product A A Product C Product B B Product C is a new product constructed by combining Product A and B into a single enclosure. Figure 3
12 12 TR V1.1.1 ( ) In this scenario all three of the above products are products in their own right with their own functionality and compliance to their respective EU directives, but may in some cases be reliant upon one of the other products for its power supply. In this scenario either product A and/or product B is a product that falls within the scope of the R&TTE Directive [1] therefore product C also falls under the scope of the R&TTE Directive [1] Scenario 2 Product A Product B Figure 4 Product A is a product in its own right and is placed upon the EU market in accordance with the relevant directives. Product B is dependent upon product A and relies upon product A for control and possibly power. Product B is physically installed within product A according to the manufacturers instruction, e.g. plug and socket, hard wiring. There may be multiple types of product B's within a single product A Scenario 3 Product A Product B Figure 5 Product A is a product in its own right and is placed upon the EU market in accordance with the relevant directives. Product B is dependent upon product A and relies upon product A for control and possibly its power supply. Product B is physically connected by either cable or fibre to product A, and the two products may be some distance apart. There may be several product B's connected to a single product A Scenario 4 Product A Product B1 Product B2 Figure 6 This scenario is a combination of the previous two scenarios. Product B1 is physically installed within product A according to the manufacturers instruction, e.g. plug and socket, hard wiring, whilst product B2 is physically connected by either cable or fibre to product A and may be some distance apart.
13 13 TR V1.1.1 ( ) Scenario 5 Product A Function B Figure 7 Product A was a product in its own right and was placed upon the EU market in accordance with the relevant directives. In this scenario an additional function, function B, is incorporated into product A during a design evolution and cannot be identified as a separate part of product A. However product A can be operated without using function B Scenario 6 Product A Function B Figure 8 Function B is part of product A which was added during design. Product A cannot be operated without using function B Scenario 7 Product A Product B Figure 9 Products A and B are products in their own right. However product A relies upon product B for its operation. Product B may work with other products. The link between product A and B may be either a physical link (e.g. cable) or non-physical (e.g. radio).
14 14 TR V1.1.1 ( ) 5 Application of harmonized standards to combined equipment 5.1 Functional dependencies The following table takes the above scenarios, from clause 4.1, and places them into a category dependant upon whether the individual products/functions can operate independently of each other. The final column in the table indicates where guidance upon application of harmonized standards can be found. Multi radio products, as detailed in clause 6, can be in any of the scenarios described in clause 4.1. Product A Works alone Does not work alone Table 1: Functional dependencies Product/Function B Works alone Does not work alone Category Reference clause in present document for application of harmonized standards Scenario 1 X X Scenario 2 X X Scenario 3 X X Scenario 4 X X and Scenario 5 X X Scenario 6 X X Scenario 7 X X NOTE: Product B can mean more than one product. 5.2 Category 1 - where all products can operate independently of each other In this category it is assumed that the individual products will have been assessed and shown to be in compliance with the relevant directives. The combined equipment should comply with article 3.1(b) of the R&TTE Directive [1]. Individual products used within the combined equipment have complete functionality in their own right. If used on their own then the relevant harmonized EMC standard for that product should be used to demonstrate conformity for that product. Evaluation of combined equipment may be made by reviewing the existing assessments of the individual products. If an individual product is used according to its manufacturers instructions, and it has been previously assessed in a configuration which is representative of the combined equipment usage, it is not necessary to re-assess that product or the combined equipment. Additional assessment of the combined equipment should only be made where there is insufficient information to make an evaluation, or where the results of the evaluation are unclear Emissions It is recognized that the individual products which make up the combined equipment may have been assessed to different harmonized EMC standards with differing emission limits. However, for combined equipment, the limits used to demonstrate compliance should be taken from the harmonized EMC standard for the primary product (declared by the manufacturer). Ports not covered in the harmonized EMC standard relevant to the primary product should be assessed against the details set out for these ports in the harmonized EMC standards for the other products contained within the combined equipment. Where one or more of the products is a radio the exclusion band details should be taken from the harmonized radio product EMC standard and taken into account and applied during the EMC assessment of the combined equipment.
15 15 TR V1.1.1 ( ) Where the emissions from the combined equipment are identified as spurious emissions, as defined in ITU-R radio regulation S1.145 [23], from any radio product incorporated into the combined equipment, these emissions should be regarded as radio spurious emissions subject to article 3.2 of the R&TTE Directive [1]. The assessment of these spurious emissions can be found in the harmonized radio standard for use under article 3.2 of the R&TTE Directive [1] Immunity It is recognized that the individual products which make up the combined equipment may have been assessed to different harmonized EMC standards with differing immunity test levels, phenomena and performance criteria. However, for combined equipment, the harmonized EMC standard for the primary product (declared by the manufacturer) should be used. The following additional immunity tests should be applied to the combined equipment if not already included in the assessment of the primary product: conducted immunity on telecommunications, signal and control ports as defined in the harmonized EMC standards for the other products contained within the combined equipment; radiated immunity (Radio Frequency electromagnetic field) as defined in the harmonized EMC standards for the radio and/or telecommunication functions contained within the combined equipment. Where one or more of the products is a radio the exclusion band details should be taken from the harmonized radio product EMC standard and be taken into account and applied during the EMC assessment of the combined equipment. If additional immunity tests have been performed then the relevant performance criteria should be taken from the harmonized EMC product standard containing these tests. Where the combined equipment relies on one or more communications links for its operation, then these links should be maintained during immunity testing in accordance with the relevant harmonized EMC product standard, and any degradation of performance should be in accordance with the manufacturers declaration. For a combined equipment containing a radio, loss of link or degradation of performance should not be considered as a non-compliance if this is due to a narrow band receiver response as defined in the relevant radio EMC product harmonized standard. For combined equipment containing radio products the performance criteria should include that the transmitter is not unintentionally operated during testing. The actual performance criteria used should be recorded in any subsequent test report. 5.3 Category 2 - where one or more of the individual products cannot operate independently Within this category of combined equipment, the product providing the control functions can be operated separately and therefore will have been assessed to the relevant harmonized EMC standard for that product. The combined equipment shall comply with article 3.1(b) of the R&TTE Directive [1] Products physically incorporated within another product When a combined equipment is made up from the incorporation of one or more products into another product, then the assessment of the combined equipment should be on the same basis as that recommended in clauses and Products connected to, but not physically incorporated within, another product When a combined equipment is made up from one or more products connected to, but not physically incorporated into another product, then the EMC assessment may be carried out using one of the following options: where the testing of the combined equipment may be performed on a complete configuration which is representative of typical configuration, then the assessment should be on the same basis as that recommended in clauses and 5.2.2;
16 16 TR V1.1.1 ( ) where the physical and/or cable distance between the various parts of the combined equipment is such that testing of the combination would not be representative of a typical configuration, then each part of the combined equipment may be evaluated individually to the relevant harmonized EMC standard. Details of typical configurations should be declared by the manufacturer. Care should be taken during testing to provide adequate control of the individual parts in order to maintain representative operation. 5.4 Category 3 - where none of the component parts operate independently This category of combined equipment is characterized by the fact that the various component parts cannot operate independently. The combined equipment should comply with article 3.1(b) of the R&TTE Directive [1]. The primary function of the combined equipment should be declared by the manufacturer Emissions The limits and tests used to demonstrate compliance of the combined equipment should be taken from the harmonized EMC standard relevant to the primary function (declared by the manufacturer). Ports not covered in the harmonized EMC standard relevant to the primary function should be assessed against the details set out for these ports in the harmonized EMC standards for the other products/functions contained within the combined equipment. Where one or more of the functions is a radio the exclusion band details should be taken from the relevant harmonized radio product EMC standard and applied during the EMC assessment of the combined equipment. Where the emissions from the combined equipment are identified as spurious emissions, as defined in ITU-R radio regulation S1.145 [23], from any radio product incorporated into the combined equipment, these emissions should be regarded as radio spurious emissions subject to article 3.2 of the R&TTE Directive [1]. The assessment of these spurious emissions can be found in the harmonized radio standard for use under article 3.2 of the R&TTE Directive [1] Immunity The test levels, performance criteria and test methods used to demonstrate compliance of the combined equipment should be taken from the harmonized EMC standard for the primary function (declared by the manufacturer). The following additional immunity tests should be applied to combined equipment if not already included in the assessment of the primary function: radiated immunity (Radio Frequency electromagnetic field) as defined in the harmonized EMC standards for the radio and/or telecommunication functions contained within the combined equipment; conducted immunity on telecommunications signal and control ports as defined in the harmonized EMC standards for the radio and/or telecommunication functions contained within the combined equipment. If additional immunity tests have been performed then the relevant performance criteria should be taken from the harmonized EMC product standard containing these tests. Where one or more of the functions is a radio, the exclusion band details should be taken from the relevant harmonized radio product EMC standard and applied during the EMC assessment of the combined equipment. Where the combined equipment relies on one or more communications links for its operation, then these links should be maintained during immunity testing in accordance with the relevant harmonized EMC standards, and any degradation of performance should be in accordance with the manufacturers declaration. For a combined equipment containing a radio, loss of link or degradation of performance should not be considered as a non-compliance if this is due to a narrow band receiver response as defined in the relevant radio EMC product harmonized standard. For combined equipment containing radio product/function the performance criteria should include that the transmitter is not unintentionally operated during testing. The actual performance criteria used should be recorded in any subsequent test report.
17 17 TR V1.1.1 ( ) 6 Application of harmonized EMC standards to Multi-radio equipment This clause details the additional considerations when dealing with multi-radio equipment. These should take precedence in case of conflict with those determined in clause 5. For Multi-radio equipment, the applicable EMC phenomena and limits are those set out in the and for maritime equipment in the The test conditions, performance assessment and performance criteria as stated in [22] or [24] are used together with the specific product related parts of the or the for specific radio equipment. 6.1 Multi-radio equipment capable of independent transmission If the individual radio products and their corresponding radio links operate independently in normal usage (as declared by the manufacturer), then separate testing should be used. In this case the individual radio products should be assessed to the appropriate harmonized EMC product standards. 6.2 Multi-radio equipment not capable of independent transmission However, where operation of the individual radio products and their corresponding radio links is simultaneous in normal usage (as declared by the manufacturer), then separate testing should not be used. In this case testing should be performed on the complete combined equipment. An overall performance criteria is required for the combined equipment. This may be developed by examining the individual performance criteria of the various radio products involved. The performance criteria used should be declared by the manufacturer and recorded in the test report. Where multiple operational frequencies are used, exclusion bands should be defined for each of the radio products and all of these should be used during testing.
