This standard does not cover: Button link. This standards requirements will concern CMB that: Are approved for attachment to aircraft
24、 (“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-readable data (print and barcode), Are used for new airplane certification as well as retrofitting on previously-certified aircraft or syste
25、ms, 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 button. Contact Memory Button is a battery-free, read/write electronic data storage device. It can be used in environments including militar
26、y, aerospace, utility, transportation and industrial applications. Contact Memory Button enhances among others, applications such as configuration management, asset tracking, inspection and maintenance for the life of the asset it is attached to. Data stored on the Contact Memory Button, which could
27、 be available in various memory capacities, is retrieved and updated with momentary contact using a button link. Contact Memory Button should have the ability to be used with security system policies. For the definition of the requirements concerning security, refer to common criteria. These criteri
