Acoustics - Noise test code for fastener driving tools - Engineering method

This standard applies to fastener driving tools. The noise created by fastener driving tools directly affecting the surrounding environment (noise emission) should calculated in a uniform procedure enabling comparison of the final results. This standard contains provisions concerning the execution of the measurement of airborne noise in the vicinity of fastener driving tools and the measurement of emission sound pressure levels at the work station under defined operating conditions.
The determination of the noise emission levels of fastener driving tools in accordance with this standard is valid for all actuating systems in accordance with EN 792-13.
The results can be used to compare the noise emissions of different fastener driving tools.
NOTE   The special conditions at the work place (e.g. shape and foundation of the workpiece, quantity and frequency of the driving processes) can influence the noise emission to an important degree.

Overview

EN 12549:1999+A1:2008 - Acoustics: Noise test code for fastener driving tools (Engineering method) specifies a uniform engineering method to measure and report airborne noise emitted by handheld fastener driving tools (nailers, staplers, pinners, etc.). The standard defines procedures for determining both the A‑weighted single‑event sound power level (LWA,1s) and the A‑weighted single‑event emission sound pressure level at the work station (LpA,1s) so that noise emission values are comparable between tools and suitable for regulatory declaration.

Key Topics and Requirements

• Scope: Applies to fastener driving tools and is valid for all actuating systems in accordance with EN 792‑13. Results are intended for direct comparison of tool noise emissions.
• Measurement geometry: Uses a hypothetical cube measurement surface surrounding the tool with nine measurement positions at a 1.00 m distance from the tool centre. Centre point height is 1.00 ± 0.10 m above the floor. The enveloping measurement surface area S = 20 m² (superficial measure LS = 10·log(S/S0) = 13 dB).
• Work station measurement: Operator position (O) is measured at 0.3 m horizontally and 0.5 m vertically from the tool centre on the handle side; this gives the emission sound pressure level relevant to the operator’s exposure.
• Measurement procedure: For each position, the A‑weighted single‑event sound pressure level is measured five times, arithmetic means are used for calculations. For continuous actuation tools, equivalent time‑based measurements are taken and event counts recorded.
• Calculations: LpA,1s values on the measurement surface are combined to obtain LWA,1s per the standard’s formulae (see clause 5), and corrections (background/environment) applied where necessary.
• Uncertainty & accuracy: Measurement accuracy is grade 2, and measurement uncertainty must be stated in accordance with EN ISO 3744 and related guidance.
• Recommended environment & instruments: Use engineering‑level acoustical test methods (e.g., anechoic room over reflecting plane) and instruments compliant with standards such as EN 60651 / EN 60804 and EN ISO 11201.

Applications and Who Uses It

• Manufacturers: produce declared noise emission data required by the Machinery Directive and product documentation.
• Test laboratories & acoustic consultants: perform standardized noise testing and verification.
• Safety officers & procurement teams: compare tool noise levels for hearing protection planning and tool selection.
• Design engineers: evaluate and reduce noise at source during tool development.

Practical note: workplace specifics (workpiece shape, foundation, operation frequency) can significantly affect emitted noise - manufacturers must declare test operating conditions.

The design of these fastener driving tools is such that in normal circumstances they may be carried by one person and are handheld during the driving process. NOTE Fastener driving tools are named e.g. nailers, staplers, tackers, pinners. The energy required for the driving process can be drawn e.g. from compressed air, electrical current, combustible gases, tension springs. Fasteners may be e.g. nails, staples, pins, brads, corrugated fasteners and screws used as nails. The frequency of the driving processes with a fastener driving tool varies in time according to the operation purpose (e.g. 500 driving processes per day may be carried out with a big fastener driving tool against 20 per second with a small one). The time duration of one driving process is normally in a range of 0,1 s or shorter. 5 Sound power level determination 5.1 Basic International Standards to be used If it is required to determine the sound power level, basic sound power measurement standards shall be used, such as EN ISO 3744.
