Overview

EN 1093-9:1998+A1:2008 - Safety of machinery: Evaluation of the emission of airborne hazardous substances - Part 9: Pollutant concentration parameter, room method - specifies a standardized room test to measure the pollutant concentration parameter (Pcr) produced by machines. The method applies to machines operated in a controlled test room, with local exhaust ventilation (LEV) ≥ 500 m3/h or machines without recirculated air. The measured Pcr helps quantify airborne emissions for performance evaluation, product comparison and state-of-the-art assessments.

Key topics and technical requirements

• Test environment
  • Test room volume greater than 200 m3.
  • Machine at least 2 m from walls and ceiling; no other sources of the specified pollutant.
  • No recirculated air from LEV; supply air designed to avoid cross-draughts.
  • Verify airflow patterns (e.g., smoke cartridge) so measurement points’ air flows toward LEV.
• Measurement points and sampling
  • Minimum of 4 measurement points positioned empirically in major emission zones; exact locations defined in relevant type C standards.
  • At least three measurements per point to capture variability.
• Operation and measurement procedures
  • Machines operated according to intended use, manufacturer instructions and type C standards (e.g., feed rate, tooling, materials).
  • Measurement methods must conform to appropriate International/European standards; measuring time must represent normal operational cycles (including consideration of start-up emissions).
  • Instruments must be calibrated; environmental data (temperature, humidity, pressure) recorded.
• Result expression
  • Compute mean and standard deviation per test and per point.
  • Pcr = mean value + one-sided 95% confidence interval (room pollutant concentration parameter).
• Reporting
  • Test report must document machine details, test room layout, LEV description and airflow, measurement procedures and instruments, raw concentrations, Pcr and confidence interval, deviations, tester and dates.

Practical applications

EN 1093-9 supports:

• Performance evaluation of emission control on machines.
• Design improvements and verification after modifications.
• Comparative testing and ranking of machines within the same application group (same function/materials processed).
• Benchmarking and establishing state-of-the-art emission levels for product families.

Who uses this standard

• Machine manufacturers and OEMs
• Accredited test laboratories and independent certifiers
• Health, Safety & Environment (HSE) engineers
• Regulatory and conformity assessment bodies
• R&D teams working on emission control and ventilation design

• EN 1093-1 (selection of test methods)
• ENV 1070 (terminology)
• EN 292-1 / EN 292-2 (safety fundamentals)
• ISO 2602 (statistical interpretation of test results)
• References to EU Directives: Annex ZA/ZB relate this standard to Directive 98/37/EC and 2006/42/EC (machinery).
