CTIA v5.1
Where each UGP grade lands on the CTIA Wireless Device Grading Scales v5.1: cosmetic grade, primary grade and consumer tier.
The mapping
| UGP | CTIA v5.1 cosmetic | CTIA v5.1 primary | CTIA v5.1 consumer tier |
|---|---|---|---|
| New Sealed (NS) | outside the cosmetic scale | — | — |
| New Open Box (OB) | Annex B "New" | — | — |
| Like New (A) | A, with a note below | A+ (AA when an RF-shielded test passes) | Tier 2 (Premium → Tier 1) |
| Very Good (B) | B (L1–L2) | B+ | Tier 3 |
| Good (C) | B | B+ | Tier 4 |
| Acceptable (D) | C, with no cracks | C+ | — (wholesale only) |
| No grade (Repair, Parts) | D / E | D, E | — |
Notes
- The primary grade assumes CTIA functional class 1, battery type 1, and customer and enterprise locks clear. Every UGP grade guarantees all three.
- Like New and CTIA A. UGP Like New allows up to two S1 marks on the display (zone AA); CTIA A allows none. A Like New unit can therefore map to CTIA B, and only Premium (A0) maps to CTIA A.
- Acceptable is never cracked. CTIA D includes a cracked display cover glass and maps to no UGP grade. A cracked device under UGP has status Repair.
The inspection conditions
UGP's viewing conditions follow the inspection conditions in CTIA Certification's Wireless Device Grading Scales: Criteria and Definitions v5.1, §2.5, so that this mapping holds: cool-white light of at least 500 lumens, the device about 45 cm (18 in) away, about 4 seconds per surface and 6 on the display. UGP aligns its defect sizes with CTIA v5.1 for the same reason; its tolerance counts are its own. §5.4 · §2
The functional class
A UGP record for a phone, tablet or watch can emit the CTIA functional class, derived from its recorded faults using CTIA's published classification. Fully functional (FF) always derives class 1; any other class is emitted as derived. A derived CTIA vector is labelled derived from UGP v1.0. §7.5 · §15
