Overview

EN 1915-4:2004/prA1 is a CEN draft amendment to EN 1915-4 (Aircraft ground support equipment - General requirements - Part 4: Noise measurement methods and reduction). It updates and clarifies noise measurement and noise‑reduction requirements for aircraft ground support equipment (GSE). The amendment aligns EN 1915-4 with current ISO/CEN acoustics and machinery safety standards and adds informative relationship to the EU Machinery Directive (2006/42/EC).

Key topics and technical requirements

• Scope: Noise measurement methods and reduction for aircraft ground support equipment (GSE).
• Standards alignment: Replaces older references (e.g. EN 1070, EN ISO 11201:1995, EN ISO 3744:1995) with current shorthand references (EN ISO 12100, EN ISO 11201, EN ISO 3744, EN ISO 9614, EN ISO 4871) to harmonize terminology and test methods.
• Noise threshold change: The level referenced in clause 5.1 is revised from 85 dB to 80 dB.
• Measurement uncertainty: Introduces a default measurement uncertainty parameter σ = 2.5 dB (σ_R = 2.5 dB); smaller σ values may be used when supported by measurements for a machine family.
• Surface and test conditions: Requires a smooth test surface (e.g., smoothened concrete or asphalt) to avoid rattling noises that could bias results.
• Sound power / intensity methods: Updates bibliography and references to established acoustics methods such as EN ISO 3744 (sound power) and EN ISO 9614 (sound intensity).
• Regulatory linkage: Adds Annex ZB outlining conformity presumption with Essential Requirements 1.5.8 and 1.7.4.2(u) of Directive 2006/42/EC when the standard is cited in the Official Journal.

Practical applications and who uses it

• Manufacturers of GSE - implement standardized noise measurement methods during design and production to reduce radiated noise and demonstrate compliance.
• Test laboratories and acoustic consultants - perform sound power and intensity measurements using the referenced EN/ISO methods and apply the specified uncertainty values and surface requirements.
• Airport operators and ground handlers - assess and select low-noise equipment to meet local environmental and occupational noise limits.
• Compliance officers and certification bodies - use the standard (when adopted) to assess conformity with the Machinery Directive and national transpositions.
• Design engineers - apply recommended low-noise practices referenced via EN ISO 11688 series in the bibliography.

Related standards

• EN ISO 12100 (machinery safety concepts)
• EN ISO 11201 (acoustics - noise emission - measurement of airborne noise at workstations)
• EN ISO 3744 (sound power determination)
• EN ISO 9614‑1 / EN ISO 9614‑2 (sound intensity methods)
• EN ISO 4871 (acoustics - declaration and verification of noise emission)
