SIST EN IEC 60645-6:2022/A1:2026 is the Slovenian adoption of the European amendment EN IEC 60645-6:2022/A1:2026, based on IEC 60645-6:2022/AMD1:2026. It updates the standard for instruments used to measure otoacoustic emissions, mainly by redirecting references to IEC 60645-7:2025 and clarifying one acceptance-limit wording for DPOAE primary tones. It is written for people who specify, make, test, or buy audiometric equipment.

What does SIST EN IEC 60645-6:2022/A1:2026 specify?

SIST EN IEC 60645-6:2022/A1:2026 specifies amendments to EN IEC 60645-6:2022 for instruments that measure otoacoustic emissions. The amendment is focused and does not rewrite the whole standard; it updates a few references and one wording point used in practice for stimulus levels.

The document is organized as a European foreword, an introduction to the amendment, Clause 2 on normative references, Clause 3 on terms and definitions, Clause 5 on general specifications, and Annex ZA on European reference mapping.

What are the key requirements of SIST EN IEC 60645-6:2022/A1:2026?

SIST EN IEC 60645-6:2022/A1:2026 mainly updates where users must look for supporting requirements and clarifies how one stimulus-level limit is read. For a manufacturer or test lab, the practical effect is that conformity checks now point to the newer companion standard and use clearer wording for DPOAE primary tones.

Normative references and supporting signal requirements

• Clause 2 replaces the reference to IEC 60645-3:2020 with IEC 60645-7:2025. In practice, any requirement that depended on the old short-duration signal reference now points to the current standard.
• Annex ZA mirrors that update with the European publication EN IEC 60645-7:2025. This matters for national adoption and for readers who work with European editions.

Terms and measurement language

• Clause 3.9 updates the note to the term peak-to-peak equivalent sound pressure level (peSPL). That keeps the definition aligned with the current reference for short-duration signals.
• Clause 5.1.1 changes the general requirements to refer to the relevant parts of Clause 6 and Clause 7 of IEC 60645-7:2025. In practice, this ties the general requirements for test signals to the newer companion standard.

Stimulus types and DPOAE wording

• Clause 5.1.2.2 for transient evoked otoacoustic emissions (TEOAE) replaces the old reference with IEC 60645-7:2025. Users working with TEOAE equipment should check the updated reference path.
• Clause 5.1.4.3 for distortion product otoacoustic emissions (DPOAE) clarifies the acceptance limits for the primary tones as two-sided. This matters when setting up or verifying stimulus levels, because the limit is to be read symmetrically.

Overall effect of the amendment

• The amendment says it introduces no technical change to the document. The practical value is mainly in keeping the standard aligned with the current reference set and removing ambiguity in one wording point.

What terms does SIST EN IEC 60645-6:2022/A1:2026 define?

SIST EN IEC 60645-6:2022/A1:2026 uses a small set of terms that are central to otoacoustic emission measurements.

• Otoacoustic emissions are sounds generated by the ear, and the standard concerns instruments that measure them.
• Transient evoked otoacoustic emissions (TEOAE) are otoacoustic emissions elicited by brief stimuli.
• Distortion product otoacoustic emissions (DPOAE) are emissions generated when the ear is driven by two primary tones.
• Primary tones are the two stimulus tones used to create a DPOAE measurement.
• Peak-to-peak equivalent sound pressure level (peSPL) is a way to express the level of a short-duration signal on a peak-to-peak equivalent basis.
• Short-duration signals are brief test signals whose requirements are now pointed to IEC 60645-7:2025.

Who uses SIST EN IEC 60645-6:2022/A1:2026?

SIST EN IEC 60645-6:2022/A1:2026 is used by manufacturers of audiometric equipment, especially makers of instruments for otoacoustic emission testing. It is also used by test laboratories, clinical audiology teams, procurement staff, and quality or compliance teams that need to specify or verify measurement performance.

What changed in SIST EN IEC 60645-6:2022/A1:2026 from the previous edition?

SIST EN IEC 60645-6:2022/A1:2026 is Amendment 1 to EN IEC 60645-6:2022. It replaces references to IEC 60645-3:2020 with IEC 60645-7:2025 in the relevant places, and it clarifies the DPOAE primary-tone acceptance limits as two-sided wording. The amendment states that it does not introduce technical changes.

Which standards are used with SIST EN IEC 60645-6:2022/A1:2026?

SIST EN IEC 60645-6:2022/A1:2026 uses IEC 60645-7:2025 as its key normative reference. That standard supplies the current requirements for auditory evoked potentials and the short-duration signal content now referenced in Clause 2, Clause 3.9, Clause 5.1.1, and Clause 5.1.2.2.

What does the SIST EN IEC 60645-6:2022/A1:2026 document contain?

SIST EN IEC 60645-6:2022/A1:2026 is a targeted amendment document rather than a full standalone specification. It contains the European foreword, the amendment introduction, the exact reference replacement in Clause 2, the note update in Clause 3, the wording changes in Clause 5, and Annex ZA for the European publication mapping. For users, it is mainly a change record that shows where the parent standard has been updated and how those updates affect measurement language and references.
