31、Button. This standard does not cover: Button link. This standards requirements will concern CMB that: Are approved for attachment to aircraft (“airborne use”), (regulations limit operation to read/write only while on the ground), Can be integrated into labels and tags with machine-readable and human
32、-readable data (print and barcode), Are used for new airplane certification as well as retrofitting on previously-certified aircraft or systems, Use digital data for supplemental part marking and tracking. This standard can also be used for “weapon systems”. 5 General configuration CMB consists of a
33、 button. Contact Memory Button is a battery-free, read/write electronic data storage device. It can be used in environments including military, aerospace, utility, transportation and industrial applications. Contact Memory Button enhances among others, applications such as configuration management,
34、asset tracking, inspection and maintenance for the life of the asset it is attached to. Data stored on the Contact Memory Button, which could be available in various memory capacities, is retrieved and updated with momentary contact using a button link. Contact Memory Button should have the ability
35、to be used with security system policies. For the definition of the requirements concerning security, refer to common criteria. These criteria consider both intrinsic performance of the solution and the performance of their use in order to facilitate the choice of a solution adapted to their needs.
36、Contact Memory Button shall be permanently affixed to parts using approved mechanical or adhesive methods, processes and products. Contact Memory Button will have the possibility to be embeded into parts. BS EN 4819:2012EN 4819:2012 (E) 7 6 Applicability This document establishes the documentation r
