Overview

SIST EN 301 489-27 V2.1.1:2017 is a harmonised European standard developed by SIST and based on ETSI EN 301 489-27. It provides comprehensive requirements for ElectroMagnetic Compatibility (EMC) assessment of radio transceivers associated with Ultra Low Power Active Medical Implants (ULP-AMI) and corresponding external Peripheral Devices (ULP-AMI-P). The standard supports compliance with the essential EMC requirements defined in Article 3.1(b) of Directive 2014/53/EU (Radio Equipment Directive - RED).

This standard specifically addresses the unique operational and EMC considerations for body-implanted radio devices as well as their associated external peripherals, ensuring that such devices do not cause or suffer from unacceptable electromagnetic disturbances in practical healthcare environments.

Key Topics

• Scope of EMC Compliance: The document outlines EMC requirements uniquely applicable to ULP-AMI and ULP-AMI-P devices, focusing on their radio functions. Requirements concerning antenna and enclosure port emissions are referenced in separate product standards.
• Test Conditions and Performance Assessment: It defines specific test conditions, arrangements for test signals, and exclusion band concepts to ensure realistic and reproducible measurement environments, including the use of a simulated man for implant testing.
• Device Classification: ULP-AMI and ULP-AMI-P devices are classified by risk, following IEC EN 60601-1-2 principles. Each class has corresponding performance criteria to match the device’s medical criticality.
• Immunity and Emission Requirements: The standard details emission and immunity levels, referencing ETSI EN 301 489-1, but adds specific provisions where necessary for medical implant communication systems.
• Functional Integrity: Key requirements ensure that devices maintain essential functions, recover gracefully from electromagnetic disturbances, and avoid catastrophic failures, unwanted resets, or unintended operations.

Applications

SIST EN 301 489-27 V2.1.1:2017 applies directly to:

• Manufacturers of ULP-AMI and ULP-AMI-P devices: Provides a clear framework for demonstrating EMC compliance with European regulations, essential for product certification and CE marking.
• Test Laboratories: Supplies consistent test conditions, procedures, and performance criteria for evaluating EMC of radio-enabled medical devices, ensuring reliable and repeatable results.
• Regulatory Bodies and Notified Bodies: Offers a harmonised approach to assessing product compliance with Directive 2014/53/EU, streamlining market access for innovative medical implants and their controllers.
• Product Developers: Assists R&D teams in designing products that meet stringent EMC requirements, avoiding costly redesigns and ensuring patient safety.

The standard is particularly relevant for active medical implants such as pacemakers, neurostimulators, drug delivery pumps, and their external controllers or programmers operating in the 402–405 MHz band. By establishing robust EMC provisions, it helps minimize risks of electromagnetic interference in critical medical applications.

4.3 RF exclusion band of radio equipment
4.3.0 General
The emission measurement and immunity test exclusions are referred to as "exclusion bands" and are defined in the
clauses 4.3.1 and 4.3.2.
The frequencies on which the EUT is intended to operate, shall be excluded from conducted and radiated RF immunity
tests.
The frequencies on which the transmitter part of the EUT is intended to operate shall be excluded from emission
measurements when performed in transmit mode of operation.
During emission measurements, a frequency exclusion band does not apply for the receiver part of ULP-AMIs and/or
associated ULP-AMI-Ps.
4.3.1 Exclusion bands for receivers
The exclusion band for receivers (including receivers that are part of transceivers) is determined as follows:
• for receivers capable of operating on 9 or more channels within the frequency band specified in table 1 and not
having an alignment range, the lower frequency of the exclusion band is the lower frequency of the used
frequency channel minus the extension value given in table 1, and the upper frequency of the exclusion band is
the upper frequency of the used frequency channel plus the extension value given in table 1. The calculated
extension value shall be based on the operating frequency;
• for receivers capable of operating on more than one frequency and having an alignment range, the lower
frequency of the exclusion band is the lower frequency of the alignment range minus the extension value given
in table 1, and the upper frequency of the exclusion band is the upper frequency of the alignment range plus
the extension value given in table 1. The calculated extension values shall be based on the centre frequency of
the alignment range;
• for wide band receivers, i.e. receivers operating in a non-channelized arrangement, the lower frequency of the
exclusion band is the lower frequency of the intended operating band minus the extension value given in
table 1 and the upper frequency of the exclusion band is the upper frequency of the intended operating band
plus the extension value given in table 1, or the total exclusion band is twice the intended operating frequency
band of the receiver centred around the centre frequency of the intended operating band, whichever is the
greater.

4.3.2 Exclusion band for transmitters
For transmitters operating, or intended to operate, in a channelized arrangement in the 402 MHz to 405 MHz frequency
band, the exclusion band is nine times the maximum occupied bandwidth allowed for that service, centred around the
operating frequency. For the 402 MHz to 405 MHz band, the maximum occupied bandwidth is 300 kHz. The actual
occupied bandwidth is determined using the procedures in ETSI EN 301 839 [2] for measuring emission bandwidth.
For wide band transmitters, i.e. transmitters in a non-channelized frequency band, the exclusion band is twice the
intended operating frequency band (i.e. 3 MHz or less) centred around the centre frequency of the intended operating
frequency band.
In case the receiver and transmitter are tested together as a system (see clause 4.2.5) the exclusion band defined for
receivers or the exclusion band defined for transmitters shall be used, whichever is greater.

In this case both EUTs shall be located in their respective test environment and exposed simultaneously to the EMC
phenomena.
4.3 RF exclusion band of radio equipment
4.3.0 General
The emission measurement and immunity test exclusions are referred to as "exclusion bands" and are defined in the
clauses 4.3.1 and 4.3.2.
The frequencies on which the EUT is intended to operate, shall be excluded from conducted and radiated RF immunity
tests.
The frequencies on which the transmitter part of the EUT is intended to operate shall be excluded from emission
measurements when performed in transmit mode of operation.
During emission measurements, a frequency exclusion band does not apply for the receiver part of ULP-AMIs and/or
associated ULP-AMI-Ps.
4.3.1 Exclusion bands for receivers
The exclusion band for receivers (including receivers that are part of transceivers) is determined as follows:
• for receivers capable of operating on 9 or more channels within the frequency band specified in table 1 and not
having an alignment range, the lower frequency of the exclusion band is the lower frequency of the used
frequency channel minus the extension value given in table 1, and the upper frequency of the exclusion band is
the upper frequency of the used frequency channel plus the extension value given in table 1. The calculated
extension value shall be based on the operating frequency;
• for receivers capable of operating on more than one frequency and having an alignment range, the lower
frequency of the exclusion band is the lower frequency of the alignment range minus the extension value given
in table 1, and the upper frequency of the exclusion band is the upper frequency of the alignment range plus
the extension value given in table 1. The calculated extension values shall be based on the centre frequency of
the alignment range;
• for wide band receivers, i.e. receivers operating in a non-channelized arrangement, the lower frequency of the
exclusion band is the lower frequency of the intended operating band minus the extension value given in
table 1 and the upper frequency of the exclusion band is the upper frequency of the intended operating band
plus the extension value given in table 1, or the total exclusion band is twice the intended operating frequency
band of the receiver centred around the centre frequency of the intended operating band, whichever is the
greater.

4.3.2 Exclusion band for transmitters
For transmitters operating, or intended to operate, in a channelized arrangement in the 402 MHz to 405 MHz frequency
band, the exclusion band is nine times the maximum occupied bandwidth allowed for that service, centred around the
operating frequency. For the 402 MHz to 405 MHz band, the maximum occupied bandwidth is 300 kHz. The actual
occupied bandwidth is determined using the procedures in ETSI EN 301 839 [2] for measuring emission bandwidth.
For wide band transmitters, i.e. transmitters in a non-channelized frequency band, the exclusion band is twice the
intended operating frequency band (i.e. 3 MHz or less) centred around the centre frequency of the intended operating
frequency band.
In case the receiver and transmitter are tested together as a system (see clause 4.2.5) the exclusion band defined for
receivers or the exclusi

Whenever the Equipment Under Test (EUT) is provided with a detachable antenna, the EUT shall be tested with the antenna fitted in a manner typical of normal intended use, unless otherwise specified. If the EUT can be used with several types of antenna the test shall be repeated for each type of antenna. ULP-AMI devices (active medical implants) are designed to be implanted within a human body. These radio systems are isolated from disturbances by the surrounding body tissue. In order to adequately assess the EMC characteristics of active medical implants devices , the use of a simulated man is necessary. See annex C for additional details. The provisions of annex C are intended to provide an operational environment that simulates, to the extent possible, actual usage conditions for internal implanted devices. It is necessary to use this or another appropriate special fixture when making emission measurements and immunity tests with radiated RF fields. SIST EN 301 489-27 V2.1.1:2017

In this case both EUTs shall be located in their respective test environment and exposed simultaneously to the EMC phenomena. 4.3 RF exclusion band of radio equipment 4.3.0 General The emission measurement and immunity test exclusions are referred to as "exclusion bands" and are defined in the clauses 4.3.1 and 4.3.2. The frequencies on which the EUT is intended to operate, shall be excluded from conducted and radiated RF immunity tests. The frequencies on which the transmitter part of the EUT is intended to operate shall be excluded from emission measurements when performed in transmit mode of operation. During emission measurements, a frequency exclusion band does not apply for the receiver part of ULP-AMIs and/or associated ULP-AMI-Ps. 4.3.1 Exclusion bands for receivers The exclusion band for receivers (including receivers that are part of transceivers) is determined as follows: • for receivers capable of operating on 9 or more channels within the frequency band specified in table 1 and not having an alignment range, the lower frequency of the exclusion band is the lower frequency of the used frequency channel minus the extension value given in table 1, and the upper frequency of the exclusion band is the upper frequency of the used frequency channel plus the extension value given in table 1. The calculated extension value shall be based on the operating frequency; • for receivers capable of operating on more than one frequency and having an alignment range, the lower frequency of the exclusion band is the lower frequency of the alignment range minus the extension value given in table 1, and the upper frequency of the exclusion band is the upper frequency of the alignment range plus the extension value given in table 1. The calculated extension values shall be based on the centre frequency of the alignment range; • for wide band receivers, i.e. receivers operating in a non-channelized arrangement, the lower frequency of the exclusion band is the lower frequency of the intended operating band minus the extension value given in
table 1 and the upper frequency of the exclusion band is the upper frequency of the intended operating band plus the extension value given in table 1, or the total exclusion band is twice the intended operating frequency band of the receiver centred around the centre frequency of the intended operating band, whichever is the greater.
