Earbuds
The earbuds profile pack is not published yet. Until it is, earbuds are graded only on UGP's generic axes, as provisional records.
Status in v1.0
The earbuds profile (BUD in a core code) is listed in v1.0 as a profile pack to come. §16
Until the pack is published, a device in this class may be graded only for the axes UGP defines generically, and its record carries profile_status: "provisional". §1.2
What the pack will define
From the §16 table: the case, left bud and right bud as a matched set; a charge-hold test per cell; and the ear tips in the kit. The fault codes it will use are already in the fault lexicon.
A profile pack carries its own version and the core version it depends on, and is released as a MINOR version. §18.2 · §18.3
Help shape it
The priority order of the profile packs is open for comment during the public comment period. Inspection data, fault lists and kit lists for earbuds are welcome through Propose a change (type "New profile pack"). §19.3
