Analyzing the Impact of Amending the EMC Directive

Teresa Fenn and Jan Vernon

A study was conducted to assess the overall level of costs and benefits from the enforcement of the draft amendment of the Electromagnetic Compatibility Directive.

Illustration by TAISHA PAYTON

The Electromagnetic Compatibility (EMC) Directive (89/336/EEC) was adopted on January 1, 1992. All electrical and electronic apparatus marketed in the European Economic Area (EEA) must satisfy the requirements of the directive and carry the CE marking. Following a review as part of the Simpler Legislation for the Internal Market (SLIM) process, an amendment to the directive was drafted. The European Commission's DG Enterprise contracted Risk & Policy Analysts Ltd. (London) to conduct a cost-benefit assessment of the amendment.

Data on the potential impacts of the amendment, and the costs and benefits associated with these effects, were drawn from a literature search and consultation with more than 400 organizations, companies, and individuals potentially affected by the amendment. The primary effects of the amendment are shown in Table I.

Change Implications
More-coherent scope
and product definition
Sets out the product categories
subject to the EMC Directive,
describing each in detail. Excludes
low-emission equipment that,
experience shows, works satisfactorily
in its intended area of use.
Regime for fixed
installations
Provides specific requirements with
separate provisions and essential
requirements for fixed installations
that may cause or suffer from
electromagnetic disturbances.
Notified body report
for apparatus
Under the directive, manufacturers
applying standards only in part or
not at all must include a report or
certificate from a certification body
in the technical construction file.
The amendment states that only a
report will be required and specifies
the content of the report. Options
in the amendment make the use of
notified bodies either voluntary or
compulsory.
Specification of
essential requirements
Provides a list of essential
requirements. The apparatus
must meet the requirements
without external devices unless
marketed with the apparatus, and
manufacturers must provide
specific information, as given in
Annex 1 of the amendment.
Clarification of the
use of harmonized
standards
Includes an annex containing detailed
specifications on the correct
application of harmonized standards.

Table I. The changes introduced by the amendment to the EMC Directive and the implications of those changes.

Effects of the Amendment

The study assessed the effect of the amendment on six different groups:

  • Manufacturers and suppliers of apparatus.
  • Installers and users of installations.
  • Certifying laboratories, notified bodies, and competent bodies.
  • Professional and private end-users of equipment and consumers of appliances.
  • Users and operators of radio, telecommunications, and electricity networks.
  • Public authorities with competence on EMC issues.

Manufacturers and Suppliers

Manufacturers and suppliers indicated that the costs of compliance with the current directive range from 1 to 5% of a product's price. Respondents anticipated both costs and benefits arising from the changes suggested in the draft amendment.

Costs. The main costs identified were annual costs of 210 million ($190 million) to 620 million ($570 million) to ensure that signal-carrying ready-made connecting devices comply with the directive. Other costs included one-off costs of 1.2 million ($1.1 million) to 12 million ($11 million) to redesign equipment so that it meets the requirements of the directive without the use of additional devices, and annual costs of 1.2 million ($1.1 million) to €6 million ($5.5 million) for manufacturers of additional devices from loss of sales. This group also cited annual costs of 90 million ($83 million) to 220 million ($200 million) incurred in providing the full range of information required by the amendment.

Benefits. Among the main benefits identified were potential benefits of 120 million ($110 million) to 320 million ($290 million) to manufacturers of signal-carrying ready-made connecting devices used with telecommunications associated with a consistent classification system for their products. Because declarations of conformity would no longer be required for one-off equipment for use in fixed installations, annual benefits of 39 million ($36 million) to 120 million ($110 million) were predicted for manufacturers of this equipment. Manufacturers would also see annual benefits of 130,000 ($120,000) to 2.5 million ($2.3 million) from reduced use of notified body reports if their use was made voluntary.

Some manufacturers were concerned that the wording of Annex 4 to the amendment could increase the amount of testing required to demonstrate compliance with the directive. Others did not share this view, but if the respondents involved did carry out the additional testing that they believe might be required, this could result in annual costs of350 million ($320 million) to 1,000 million ($920 million). Overall, it is expected that manufacturers will experience net costs under the amendment.

Installers and Users of Installations

A low level of response from this group meant that there was considerable uncertainty attached to the results. This uncertainty was increased by inconsistency between responses on the likely impact of the proposed regime for fixed installations. For example, one respondent indicated that he or she expected compliance costs to decrease by 40%; if this reduction in costs were repeated across all installers, it could result in annual cost savings of 63 million ($58 million) to 570 million ($520 million). However, another respondent indicated that costs would increase due to the need for testing in the case of complaints. If such costs were realized by all installers, the total costs for fixed installations are estimated to range from 29 million ($27 million) to 76 million ($70 million).

The costs identified may be an overestimate because they assume that no testing following complaints is currently carried out. In practice, this is unlikely, and the costs may simply represent a transfer from installation users to installers.

Certification, Notified, and Competent Bodies

Responses received from this group on the effect of the amendment were also inconsistent. Some respondents envisioned a reduction in turnover of between 5 and 70% arising from a more-coherent scope and product definition under the amendment. However, others anticipated that their turnover would increase by 2.5 to 3.5% rather than decrease.

Notified bodies also expect costs of 3.6 million ($3.3 million) to 8.1 million ($7.4 million) to arise from the procedure for fixed installations, which will result from a reduction in level of work. Similarly, they predict that a move to voluntary use of notified bodies would also reduce their level of work, leading to annual costs of 490,000 ($450,000) to 690,000 ($630,000). One respondent indicated that there could be benefits associated with the requirement for a notified body report (rather than a certificate). This benefit is estimated at 630,000 ($580,000) if all notified bodies were to experience such a benefit.

Overall, notified bodies may face net costs. However, the costs associated with a reduction in the level of work as a result of a more-coherent scope and product definition are inconsistent with responses from manufacturers. Taking the predicted benefits from the additional work required to address signal-carrying ready-made connecting devices (700,000 {$640,000} to 19 million {$17 million}) would mean that notified bodies may experience net benefits.

End-Users of Equipment and Appliances

Consumer and user awareness of EMC arises mainly through experience of electromagnetic interference (EMI). Of the consumer organizations contacted, 64% considered that consumers do experience such problems, mainly because these organizations receive complaints about EMI. They also believe that consumers are likely to contact public authorities when they experience EMI problems, so the level of complaints to authorities may be a good indicator of the level of EMI problems.

Half of the respondents believed that the amendment would result in reduced levels of EMI; the remainder did not think that EMI levels would change. Responses also indicated that consumers might be willing to pay a premium for equipment that avoided EMI problems, in contrast to the views of manufacturers that such a premium would not be feasible.

The main costs faced by users relating to the amendment include increased prices. The increases were attributed to the costs manufacturers pass on to ensure the compliance of ready-made connecting devices, the costs of redesign to ensure that apparatuses meet the requirements without additional devices, and the costs of meeting the information requirements of the amendment. End-user costs may also include reduced availability of products in cases in which manufacturers restrict sales to technically competent users.

The primary benefits to users would arise from reduced levels of EMI under the amendment, most noticeable to users of TV and radio. Sensitive populations, such as hearing-aid users and people who are electrically hypersensitive, may also see some benefits. No reliable data are available on the size of such populations or the extent of problems experienced, and so it proved impossible to quantify these benefits.

Users and Operators

This group includes radio, telecommunications, and electricity network operators, their professional and private users, and consumers using radios, televisions, telephones, and other forms of electronic communication. The key issue for this group is the potential for EMI to affect the operation, as well as the quality, of networks, although networks may also give rise to EMI. Network operators expect the overall level of EMI to decrease as a result of the amendment. Amateur radio users, however, expect the overall level of EMI to increase under the amendment.

Currently, network operators spend only a small sum in dealing with EMI. This is because action is only taken when EMI is detected by operators or by a third party. However, responses from organizations representing consumers indicate that a significant proportion experience EMI problems, which are most noticeable in relation to the use of networks. Therefore, these groups would benefit from a reduction in EMI.

Costs for this population arising from the amendment to the EMC Directive include:

  • Costs to network operators of 200,000 ($180,000) to 2 million ($1.8 million) from manufacturers increasing prices for equipment redesigned to meet the requirements of the directive without the use of additional devices.
  • Costs of 77 million ($71 million) to 190 million ($170 million) to network operators and users from manufacturers increasing prices for equipment to cover the costs of meeting the information requirements of the directive.

In addition, some costs may come in terms of increased EMI problems under voluntary resort to notified bodies if the amendment results in any delays in authorities determining whether to withdraw an apparatus from the market.

Benefits for network operators and users relate to the amendment's potential for reducing levels of EMI. These include:

  • Benefits to network operators of 2.8 million ($2.6 million) and to network users of 12 million ($11 million) to 50 million ($46 million) from reduced EMI associated with the regime for fixed installations.
  • Benefits to network operators of 150,000 ($140,000) and to network users of 700,000 ($640,000) to 2.8 million ($2.6 million) from reduced EMI associated with apparatuses meeting the requirements of the directive without additional devices.
  • Benefits to network operators of 1.4 million ($1.3 million) and to network users of 6 million ($5.5 million) to 26 million ($24 million) from reduced EMI associated with the information requirements of the amendment.

Some benefits may arise from reduced EMI associated with the inclusion of ready-made connecting devices within the scope of the directive. It was not possible to quantify these benefits. Overall, this group may face net costs from the amendment, with most of the costs borne by network operators.

Public Authorities

Public authorities in each member state are responsible for enforcing the EMC Directive and for dealing with complaints about EMI. Public authorities responding to the study believed that most variables would result in no change in the effect of the EMC Directive for them.

The main costs for public authorities occur as a result of increased workload associated from the application of the directive to ready-made connecting devices. Another potential cost may result from the increased time to withdraw noncompliant products from the market because of the voluntary use of notified bodies.

Benefits associated with the amendment are expected to come from easier identification of products because of new information requirements in the amendment. Overall, the amendment is anticipated to result in net costs to public authorities.

The Qualitative Costs and Benefits

A significant number of costs and benefits could not be quantified. For example, some manufacturers predicted costs from additional training and staff education in cases in which notified bodies will not be used. Installers and operators of fixed installations predicted increased costs due to the need to determine who is responsible for ensuring compliance. Such costs could be significant if litigation is required.

Some manufacturers indicate an increase in costs due to delays in getting products to market in which competent bodies are replaced by notified bodies. Such delays could be seen in countries where there is a limit on the number of notified bodies. If the level of EMI were reduced, certain users and operators of networks would see qualitative benefits ; however, if the level of EMI increases, certain users (including amateur radio users) would experience costs. Notified bodies may see an increase in their level of work in cases in which competent bodies are replaced by notified bodies.

Conclusion

Calculation of the overall level of costs and benefits suggests that there may be net costs as a result of the amendment to the EMC Directive. These may range from 1.3 billion ($1.2 million) to 3.5 billion ($3.2 billion), with a best estimate of net costs of 2.4 billion ($2.2 billion), discounted over eight years. This compares with a total production value for all manufacturers, installers, notified bodies, and networks covered by the EMC Directive, discounted over the same eight-year period, of 5700 billion ($5200 billion). The highest estimated net costs, of 3.5 billion ($3.2 billion), therefore represent only 0.06% of total production value. This can be compared with the current costs of compliance, which are estimated at 1­5% of product price.

The distribution of costs and benefits indicates that manufacturers are predicted to pay most of the costs (89­90%) but will only experience 54­68% of the benefits. Certain sectors (notably information technology manufacturers and small- and medium-sized enterprises) may experience proportionally higher costs of up to 0.5% of total production value. Network users and operators are expected to receive almost one-third of the benefits, whereas notified bodies receive between 2 and 13%. However, the number of costs and benefits that could not be quantified complicates such a comparison of costs and benefits.

About 60% of the costs are associated with having a more-coherent scope and product definition in the amendment, with information requirements for apparatuses accounting for nearly 30%. Almost all of the costs are likely to fall onto manufacturers, unless they are able to pass on some of the costs through increased product prices. The majority of the benefits (73­83%) are related to the regime for fixed installations. Manufacturers and network operators and users experience these benefits. Such benefits may offset some--but not all--of the costs that manufacturers expect to face under the amendment.
