Normative and informative references, including NIST SP 800-88 Rev. 2, ISO 2859-1 and CTIA v5.1.

Normative:

  • NIST SP 800-88 Rev. 2 (Sept. 2025), Guidelines for Media Sanitization. Rev. 1 is withdrawn, so records shall state the revision used.
  • IEEE 2883, Standard for Sanitizing Storage.
  • ISO 2859-1, Sampling procedures for inspection by attributes (lot grading, §14.5).

Informative:

  • CTIA Certification, Wireless Device Grading Scales: Criteria and Definitions, v5.1 (June 2026).
  • SERI R2v3 Equipment Categorization.
  • e-Stewards Standard v4.1.

UGP aligns its inspection method and its defect sizes with CTIA v5.1 so that the mapping in Annex D holds. It reproduces none of CTIA's tables.
