Overview

CEN/TR 15068:2009 defines a standardized measurement method for assessing the noise emitted by manual blowpipes used in gas welding, cutting, heating, brazing and soldering (per EN ISO 5172). The Technical Report is intended for comparative noise testing of blowpipes under the manufacturer’s nominal gas supply conditions. Measurements are used to report an A-weighted emission sound pressure level (LpA) for each blowpipe/nozzle combination.

Key topics and requirements

• Scope and purpose: Test method for manual blowpipes; intended only for comparative evaluations when tested under nominal conditions.
• Measurement environment: Tests shall be performed indoors with the blowpipe flame axis horizontal, at least 1.5 m from floor and ceiling and 5 m from walls.
• Sensor positioning: Microphone placed 1 m from the nozzle tip in the same horizontal plane; six measurement positions (a–f) around the nozzle are used and the maximum of the six (corrected if necessary) is reported.
• Background noise handling: Background noise must be sufficiently low; if the background is within 6–15 dB of the combined level, a correction is applied per the standard’s equation; if >15 dB difference, no correction is needed.
• Instrumentation:
  • Sound level meters meeting EN 61672-1 Class 1 or equivalent electroacoustic performance, using A-weighting and slow (S) time constant.
  • Octave-band filters, if used, must satisfy EN 61260 Class 1.
  • Pressure gauges and flowmeters at the blowpipe inlet must have an accuracy of ±3%.
• Procedure and reporting: Apply manufacturer’s nominal gas type, pressure and flow; test each nozzle interchangeably. Test report must include date, test body, conditions, equipment identification, nominal supply conditions and the measured LpA for each nozzle.

Applications and users

• Manufacturers of gas welding equipment and blowpipes - for product development, noise benchmarking and documentation.
• Independent test laboratories and conformity assessment bodies - to perform comparative noise tests and issue technical reports.
• Procurement and safety officers - to compare equipment noise performance for workplace safety and selection.
• R&D and product designers - to evaluate design changes that affect acoustic emissions.

Related standards

• EN ISO 5172 (blowpipe specifications referenced)
• EN 13622 (terminology for gas welding equipment)
• EN 61260 / IEC 61260 (octave-band and fractional-octave filters)
• EN 61672-1 (sound level meter specifications)

This standard is practical for anyone needing repeatable, comparable noise measurements of manual blowpipes to support product specification, safety assessments and equipment selection.
