EN IEC 60645-6:2022/A1:2026 is a CENELEC amendment to the European Standard for instruments used to measure otoacoustic emissions in audiometric equipment. It updates cross-references to IEC 60645-7:2025 and clarifies the acceptance limits for DPOAE primary tones. The amendment is presented as an editorial update and states that it introduces no technical changes.
What does EN IEC 60645-6:2022/A1:2026 specify?
EN IEC 60645-6:2022/A1:2026 specifies amendments to EN IEC 60645-6:2022, not a full rewrite of the base standard. It adjusts references and wording inside the existing framework for instruments that measure otoacoustic emissions.
The document is organized as an amendment with a foreword, an endorsement notice, Clause 2 on normative references, Clause 3 on terms and definitions, Clause 5 on general specifications, and Annex ZA on normative references to international publications. In practice, this means users need to apply the amendment together with the base standard so that the updated references and clarified limits are read correctly.
What are the key requirements of EN IEC 60645-6:2022/A1:2026?
The main effect of EN IEC 60645-6:2022/A1:2026 is to replace outdated references and clarify one acceptance limit statement used in the instrument requirements.
- Normative references update - Clause 2 replaces IEC 60645-3:2020 with IEC 60645-7:2025. This matters because the standard now points users to the current source for the short-duration signal requirements it relies on.
- peSPL note update - Clause 3.9 updates the note to entry for peak-to-peak equivalent sound pressure level (peSPL) to point to IEC 60645-7:2025. In practice, anyone checking the definition or its related note should use the newer reference.
- General requirements cross-reference - Clause 5.1.1 replaces the old reference to Clause 5 of IEC 60645-3:2020 with the relevant parts of Clause 6 and Clause 7 of IEC 60645-7:2025. This keeps the general requirements aligned with the new companion standard.
- TEOAE stimulus reference - Clause 5.1.2.2 updates the references in the TEOAE text from IEC 60645-3:2020 and IEC 60645-3 to IEC 60645-7:2025. That means implementers should trace the stimulus requirements through the newer publication.
- DPOAE acceptance limit wording - Clause 5.1.4.3 changes the wording to make the two-sided acceptance limits for DPOAE primary tones explicit as ±1,5 dB. This matters for setting, checking, or documenting stimulus tolerances.
- Editorial nature of the amendment - The introduction states that the amendment does not introduce technical changes. Users should therefore treat it as a maintenance update that preserves the technical intent of the base edition.
What terms does EN IEC 60645-6:2022/A1:2026 define?
- peak-to-peak equivalent sound pressure level (peSPL) - A sound pressure level expression used in the standard, with its note updated to point to IEC 60645-7:2025.
- normative references - Publications that are required for correct application of the standard because the text uses them as part of its requirements.
- short-duration signals - The signal type whose requirements are moved from IEC 60645-3:2020 to IEC 60645-7:2025 in the amendment.
- DPOAE primary tones - The stimulus tones whose acceptance limits are clarified in Clause 5.1.4.3.
- two-sided (±) acceptance limits - A tolerance form that shows permitted variation on both sides of the stated value.
- amendment - A change document that modifies the base European Standard rather than replacing it.
Who uses EN IEC 60645-6:2022/A1:2026?
EN IEC 60645-6:2022/A1:2026 is used by manufacturers, test laboratories, and conformity assessment teams working with instruments for the measurement of otoacoustic emissions. It is also relevant to engineers, quality managers, and buyers who need to verify that equipment specifications and tests follow the updated references and tolerance wording.
In practice, these users apply it when designing instruments, checking technical documentation, updating test procedures, or comparing offers against the same European standard text.
What changed in EN IEC 60645-6:2022/A1:2026 from the previous edition?
EN IEC 60645-6:2022/A1:2026 modifies EN IEC 60645-6:2022 with these stated changes:
- It replaces references to IEC 60645-3:2020 with IEC 60645-7:2025.
- It updates the note to the peSPL definition to point to IEC 60645-7:2025.
- It revises the Clause 5 references to the relevant parts of IEC 60645-7:2025.
- It clarifies the DPOAE primary tone acceptance limits as ±1,5 dB.
- It states that the amendment introduces no technical changes.
Which standards are used with EN IEC 60645-6:2022/A1:2026?
- IEC 60645-7:2025 - Provides the short-duration signal requirements now referenced throughout the amended text.
- EN IEC 60645-7:2025 - The European publication listed in Annex ZA as the corresponding European standard for the international reference.
- IEC 60645-6:2022 - The base European Standard that this amendment modifies and must be read with.
What does the EN IEC 60645-6:2022/A1:2026 document contain?
EN IEC 60645-6:2022/A1:2026 mainly contains amendment instructions that replace references and adjust wording in the base standard. It includes a foreword, the approval and implementation dates, an endorsement notice, and Annex ZA mapping the international publication to its European counterpart.
The body of the amendment updates Clause 2, Clause 3, and Clause 5. It does not add new test methods or figures; instead, it redirects users to IEC 60645-7:2025 where the referenced signal requirements now reside.
