Full title and description

DIN EN 61305-2:1998-10 — Household high-fidelity audio equipment and systems — Methods of measuring and specifying the performance — Part 2: FM radio tuners. This document is the German (DIN) adoption of EN 61305-2:1998 and is based on the international publication IEC 61305-2:1997; it specifies test methods and performance characteristics for domestic FM radio tuner units intended for hi‑fi use.

Abstract

This standard defines measurement methods and the characteristics to be specified for household high‑fidelity FM radio tuner units. It covers reception conditions for frequency‑modulated sound broadcasts (normally for systems using a rated maximum system deviation of ±75 kHz, with provisions to apply the methods to ±50 kHz systems by proportional adjustment), stereo pilot‑tone systems and the reference levels and test signals used when reporting sensitivity, frequency response, channel balance and other key performance parameters.

Scope

The standard applies to household high‑fidelity FM radio tuner units and sets out agreed procedures for measuring and declaring performance characteristics such as sensitivity (noise‑limited sensitivity for a given S/N ratio), real frequency range (response within specified dB tolerance around 1 kHz reference), channel separation and interchannel gain difference, harmonic and intermodulation distortion, audio output reference level, stereo‑demodulation performance (pilot‑tone systems) and other measurable parameters. Test signal definitions, reference conditions and measurement connections are specified to ensure repeatability and comparability of results.

Key topics and requirements

• Defined reference modulation and RF input levels for measurements (reference audio level at ±67.5 kHz excursion for the standard ±75 kHz system).
• Sensitivity measurement method (noise‑limited sensitivity expressed as input level in dB(fW) for a specified S/N ratio and using defined filters).
• Frequency response requirements and measurement over the usable band (response variation limits, typically ±1.5 dB around 1 kHz reference unless otherwise specified).
• Stereo pilot‑tone and stereo decoding performance tests (including conditions for reporting stereo performance and deviations for ±50 kHz systems by proportional adjustment).
• Interchannel gain/difference, harmonic and intermodulation distortion measurement procedures and reporting formats.
• Reference connections, environmental/test conditions and required indication of measurement terminals and any user‑accessible level controls used during testing.

Typical use and users

Used by hi‑fi equipment manufacturers, product test laboratories, conformity assessment bodies and technical specification writers to measure, compare and declare FM tuner performance. Also used by purchasing/specification teams and designers to ensure that FM tuner modules meet agreed performance criteria and for preparing datasheets and product declarations.

FAQ

Q: What is this standard?

A: DIN EN 61305-2:1998-10 is the German adoption of EN 61305-2:1998, itself based on IEC 61305-2:1997. It specifies standardized measurement methods and performance parameters for household FM radio tuners intended for high‑fidelity audio systems.

Q: What does it cover?

A: It covers test procedures and reporting requirements for FM tuner characteristics — sensitivity, frequency response, distortion, interchannel differences, stereo decoding (pilot tone) performance, audio output reference levels and related measurement conditions to ensure results are repeatable and comparable.

Q: Who typically uses it?

A: Hi‑fi equipment manufacturers, test laboratories, technical authors preparing datasheets or specifications, conformity assessors and procurement/specification teams looking for consistent, comparable performance data for FM tuner products.

Q: Is it current or superseded?

A: The DIN record indicates this national adoption (DIN EN 61305-2:1998-10) as the published German version of EN 61305-2:1998. The base IEC publication is IEC 61305-2:1997. Users who need the absolute current status for regulatory or compliance purposes should verify with the national standards body (DIN) or the IEC catalogue for any later amendments or replacements.

Q: Is it part of a series?

A: Yes — it is one part of the IEC/EN 61305 series that provides measurement and specification methods for household high‑fidelity audio equipment and systems; other parts address different equipment categories or additional measurement details.

Q: What are the key keywords?

A: FM tuner, hi‑fi, measurement methods, sensitivity, frequency response, stereo pilot‑tone, distortion, IEC 61305-2, DIN EN 61305-2.
