FDA’s acquired supplementary sheets explicitly connect 2-136 to 2-305 and state declaration-acceptance date(s) for the replaced recognition: recognition 2-136: 2028-07-02. Compare the exact edition and recognition limitations with your reports before agreeing the submission evidence or further work.

Exact FDA recognition records
Read these columns together. A complete recognition is not a device-specific testing instruction. The limitations are the FDA’s public metadata; the licensed standard itself is not reproduced.
| Recognition / edition | Public recognition limitations | Declaration transition context |
|---|---|---|
| FDA 2-136 ASTM E1262-88 (Reapproved 2018) Standard Guide for Performance of the Chinese Hamster Ovary Cell/Hypoxanthine Guanine Phosphoribosyl Transferase Gene Mutation Assay | Complete Complete standard [1] [4] | Exported transition expiration: 07/02/2028 |
| FDA 2-305 ASTM E1262-24 Standard Guide for Performance of Chinese Hamster Ovary Cell/Hypoxanthine Guanine Phosphoribosyl Transferase Gene Mutation Assay | Complete Complete standard [3] [6] | No expiration date is stated in this acquired export row. That is not a guarantee of indefinite recognition. |
FDA recognition of ASTM E1262-88 (Reapproved 2018) [Rec# 2-136] will be superseded by recognition of ASTM E1262-24 [Rec# 2-305]. FDA will accept declarations of conformity, in support of premarket submissions, to [Rec# 2-136] until July 2, 2028. After this transition period, declarations of conformity to [Rec# 2-136] will not be accepted.
Exact statements were reconciled on both acquired sheets and against the old recognition’s exported date. [2] [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.
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.
Reconcile each report and declaration against ASTM E1262-24 and the replaced designation(s) ASTM E1262-88 (Reapproved 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.
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.
Record planned declaration/submission dates against the FDA sheet’s acceptance date(s): recognition 2-136: 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.
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.
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.
