NEMA NU 2-2024 — FDA recognition transition and report handoff

FDA’s acquired supplementary sheets explicitly connect 12-326 to 12-382 and state declaration-acceptance date(s) for the replaced recognition: recognition 12-326: 2028-07-02. Compare the exact edition and recognition limitations with your reports before agreeing the submission evidence or further work.

What FDA’s transition statement says

Recognition 12-326 → 12-382

FDA recognition of NEMA NU 2-2018 [Rec# 12-326] will be superseded by recognition of NEMA NU 2-2024 [Rec# 12-382]. FDA will accept declarations of conformity, in support of premarket submissions, to [Rec# 12-326] until July 2, 2028. After this transition period, declarations of conformity to [Rec# 12-326] will not be accepted.

Exact statements were reconciled on both acquired sheets and against the old recognition’s exported date. [3] [5]

FDA public recognition metadata describes use of declarations of conformity in support of premarket submissions. A recognition transition is not a universal retesting deadline, a product ban, or proof that this standard applies to your device. The technical differences between licensed editions, adequacy of existing reports, buyer-specific route and final test scope remain incomplete. The comparison below does not reproduce the standard or establish FDA approval.

Method: Exact directed old-to-new statements are reconciled across both acquired sheets and the old export date. No name-similarity mapping or technical-clause inference.

Build your edition-to-report handoff matrix

Use this checklist to gather your business or product details before speaking with a specialist. The items below explain what to record and suggest useful supporting documents. You can add your own answers in the editable project brief.

  1. Which edition is actually in your evidence?

    Reconcile each report and declaration against NEMA NU 2-2024 and the replaced designation(s) NEMA NU 2-2018. Record amendments and the exact report/device revision. A similar standard number is not an edition match.

    Useful evidence: Report cover, method/edition references, amendments, declarations and device/configuration revision.

  2. Does the declaration cover the recognized portion?

    Use the complete FDA public limitation text in the comparison table. Map each listed exclusion, where present, to the relevant report sections and obtain a reasoned evidence assessment. Complete recognition still does not determine device applicability.

    Useful evidence: Recognition-to-report coverage matrix, excluded-clause assessment and the licensed edition used by your specialist.

  3. How does the recorded transition affect your submission plan?

    Record planned declaration/submission dates against the FDA sheet’s acceptance date(s): recognition 12-326: 2028-07-02. This concerns declarations supporting premarket submissions to the replaced recognition; do not treat it as a blanket deadline to retest or stop selling.

    Useful evidence: Submission plan, intended declaration references, dated recognition-sheet check and rationale for the chosen evidence route.

  4. What changed beyond the designation?

    Ask the specialist to assess the actual licensed edition/amendment differences for your design, materials, software and use environment. Separate a documented evidence gap from a changed title. This metadata comparison does not establish which tests changed or must be repeated.

    Useful evidence: Edition gap assessment tied to the device and existing evidence, with a bridging rationale and unresolved inputs.

  5. What should the quote include?

    Request a report/recognition reconciliation and a justified gap assessment first. Separate any proposed additional evaluation or testing, samples, methods, deliverables and exclusions; agree them only after applicability and existing evidence are assessed.

    Useful evidence: A scoped evidence-assessment quote; separately identified conditional work and report ownership.
