Aerospace series - Embedded tags - Choice of fixation for installation, removal and replacement of embedded tags
This document is applicable in the aeronautical domain to on-board parts and to equipment intended to be embedded or positioned on any civil or military airborne vehicle with a type certificate.
The purpose of this document is to guide design, manufacturing, maintenance and operations organizations in the installation, removal and replacement of RFID tags (UHF and HF) and Contact Memory Buttons (CMB), according to the environments defined in RTCA DO-160/EUROCAE ED-14 and according to the type of support and the expected fixation performances. This guide will provide help in the specification of the tag installation/removal functions and/or will enable the solutions on offer from tag suppliers to be enhanced.
The term "tag" used in this document covers all the tags used to store electronic data, including RFID tags and CMB tags. As a reminder, the tags can also contain information that can be read by devices other than RFID or CMB readers (e.g. bar codes - Data Matrix, QR codes, etc., and/or alphanumerical characters) and information that can be read by the naked eye without any tools (human-readable).

Série aérospatiale - Étiquettes embarquées - Choix de fixation pour pose, dépose et remplacement d’étiquettes embarquées
Le présent document s'applique, dans le domaine aéronautique, aux pièces embarquées et aux équipements destinés à être incorporés ou positionnés sur tout véhicule aéroporté civil ou militaire disposant d’un certificat de type.
L’objectif de ce document est de guider les organismes de conception, de fabrication, de maintenance et d’exploitation pour la pose, la dépose et le remplacement des étiquettes RFID (UHF et HF) et des boutons mémoire CMB (Contact Memory Button), en fonction des environnements définis dans la RTCA DO-160/EUROCAE ED-14 et selon le type de supports, ainsi que les performances de fixation attendues. Ce guide fournira une aide à la spécification des fonctions pose/dépose de l’étiquette et/ou permettra d’approfondir les solutions proposées par les fournisseurs d’étiquettes.
Le terme « étiquette » utilisé dans le présent document couvre à la fois l’ensemble des étiquettes de stockage de données électroniques et parmi celles-ci les étiquettes RFID et les étiquettes CMB. Pour rappel, les étiquettes peuvent aussi contenir des informations lisibles par un autre média que le lecteur RFID ou CMB (par exemple : code à barres - Data Matrix, QR code, etc. et/ou caractères alphanumériques) ainsi que des informations lisibles à l’œil nu sans outillage (lisibles par l'homme).

1 Scope
This document is applicable in the aeronautical domain to on-board parts and to equipment intended to
be embedded or positioned on any civil or military airborne vehicle with a type certificate.
The purpose of this document is to guide design, manufacturing, maintenance and operations
organizations in the installation, removal and replacement of RFID tags (UHF and HF) and Contact
Memory Buttons (CMB), according to the environments defined in RTCA DO-160/EUROCAE ED-14 and
according to the type of support and the expected fixation performances. This guide will provide help in
the specification of the tag installation/removal functions and/or will enable the solutions on offer from
tag suppliers to be enhanced.
The term “tag” used in this document covers all the tags used to store electronic data, including RFID tags
and CMB tags. As a reminder, the tags can also contain information that can be read by devices other than
RFID or CMB readers (e.g. bar codes - Data Matrix, QR codes, etc., and/or alphanumerical characters) and
information that can be read by the naked eye without any tools (human-readable).

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
• ISO Online browsing platform: available at https://www.iso.org/obp/ui
• IEC Electropedia: available at https://www.electropedia.org/
3.1
airborne vehicule
any machine capable of taking off and flying in the air
3.2
surface tension
physical-chemical phenomenon related to the molecular interactions of a fluid
Note 1 to entry: It results from the increase in the energy at the interface between two fluids. The system tends
towards an equilibrium corresponding to the lowest-energy configuration and therefore modifies its geometry to
reduce the surface area of this interface. The force that maintains the system in this configuration is the surface
tension.
3.3
primer
material added to make smooth coatings more adhesive to facilitate the application of the second coat
(glue, paint, etc.)
3.4
orientation
relative position of an item of equipment
EXAMPLE upright, on its side, upside down
Note 1 to entry: The orientation can affect the reading of tags.
3.5
certification
any form of recognition in accordance with a regulation or a standard based on an appropriate
assessment, certifying that a person or organization, a product, a part, or non-fixed equipment meets the
applicable requirements of this regulation or this document, as well as the delegated acts and the
implementing acts adopted on the basis thereof, through the issue of a certificate testifying this
conformity
3.6
declaration
any written declaration made under the sole responsibility of a person or an organization confirming that
the applicable requirements of a regulation or a standard, as well as the delegated acts and the
implementing acts adopted on the basis thereof and pertaining to a person or an organization, a product,
a part, or non-fixed equipment, are met
3.7
equipment
any instrument, mechanism, machine, auxiliary device, software or accessory transported onboard an
airborne vehicle by the airborne vehicle operator, which is not a part and which is used, or intended to

onboard or that has on influence on the operation of the airborne vehicle in complete safety
3.8
counterboring
machining operation consisting of counterboring a part, in particular to produce the bearing surface of a
nut, washer, etc

5 General remarks
5.1 General
The fixation of the tag to a product, item of equipment or part shall ensure that the tag remains affixed to
the product, item of equipment or part for a given duration that is consistent with the lifespan of the
product, item of equipment or part, while the tag remains operational (i.e. the tag remains readable/re-
writeable) or up to its replacement if failed.

prEN 4906:2022 (E)
The methods used to install tags vary according to the shape, size, type of material and texture of the
equipment, and to the environmental conditions under which the equipment will be monitored.
The tags shall be compatible with the intended type of fixation. The technical documentation provided by
the manufacturer usually contains this type of information.
The main criteria to be taken into consideration are as follows:
— the shape of the surface to which the tag will be affixed (flat, cylindrical, etc.), which shall meet the
manufacturer’s recommendations in terms of the flatness or the curvature of the surface;
— the size of the equipment to be identified and the area available to install the tag;
— the material of the surface of the equipment to be tagged, such as metal, plastic or textile fabric, etc.;
— the length of time for which the equipment shall be tagged (short or long term, permanent or
temporary);
— the length of time for which the e
