Overview
EN 60094-5:1993/A1:1996 (IEC 60094-5:1988/A1:1996) is the CLC/EN adoption of Part 5 of the magnetic tape sound recording and reproducing systems series: electrical magnetic tape properties. This amendment was prepared by IEC TC 60 / SC 60A and updates test conditions, measurement methods and reference equipment information to support harmonized, repeatable electrical measurements across professional and domestic audio tape systems.
Key practical updates introduced by the amendment include clarified table entries for track configurations and tape widths, revised test-equipment characteristics, and explicit methods for measuring erasure performance and noise using standard detection curves.
Key Topics
Electrical characteristics of test equipment: amendment permits the use of the psophometric curve with quasi-peak detection as specified in appendix A of IEC 268-1 for certain noise measurements, aligning tape testing with established sound-system measurement practice.
Table updates for tape formats: several table lines for domestic and professional track/width configurations are revised to reflect common 6.30 mm and 3.81 mm formats and to clarify which parameters are specified or not.
Erasing attenuation: the amendment defines erasing attenuation as the difference (dB) between a recorded signal level and the residual level after erasure. The measurement method specifies recording at reference frequency and near-maximum output, erasing with an erasing head at a current 10% higher than that producing 70 dB erasure on a reference tape, using an erasing frequency ≥ 80 kHz, and computing attenuation as:
Erasing attenuation = 20 · log10(U1 / U2)
where U1 is the reproduced voltage before erasure and U2 the residual voltage after erasure (measured through a narrowband filter).
Measuring heads and reference tapes: Appendix B is updated with head types for professional 6.30 mm tape (examples: PAM 220/PAM 227/PWM 230/PLM 210) and revised listings of primary reference tapes and manufacturers (e.g., updated references to BASF, TDK, Bogen). Some domestic head specifications are marked as not specified where applicable.
Applications
- Quality control and factory acceptance testing for magnetic tape media
- Calibration and verification of tape recorders and playback equipment
- Interoperability testing between professional and domestic audio formats
- Standardized test procedures for archival transfer, restoration and R&D
Related Standards
- IEC 60094-5:1988 (original Part 5)
- IEC 268-1 (Sound system equipment - Part 1: General) - referenced for psophometric/quasi-peak detection
- Other parts of the EN/IEC 60094 series covering mechanical and magnetic tape properties
This amendment strengthens measurement reproducibility and helps manufacturers, test laboratories and audio engineers apply consistent electrical test methods when assessing magnetic tape performance and compatibility.
