EN ISO 11200:2014 PDF

Overview

EN ISO 11200:2014 (ISO 11200:2014) is a frame standard in acoustics that defines guidance for determining emission sound pressure levels at a work station and at other specified positions. It applies to airborne sound only and introduces the ISO 11201–11205 group of basic methods. The standard is intended for general noise testing and specifically for the preparation and use of noise test codes that declare or verify machinery noise under defined conditions.

Key topics and requirements

• Scope and purpose
  • Establishes the conceptual framework for emission sound pressure level measurements and how they complement sound power data.
  • Aims to facilitate drafting consistent noise test codes for machinery families.
• Physical background and definitions
  • Explains the difference between emission sound pressure level, sound power level and occupational noise exposure (see clauses 4.1–4.3).
• Comparison of methods
  • Summarizes the measurement options provided by the ISO 11201, ISO 11202, ISO 11203, ISO 11204 and ISO 11205 standards and compares their applicability.
• Selection guidance
  • Provides criteria for selecting the most appropriate method(s) in typical practical situations, including handling source directivity, test environment and specified positions.
• Measurement uncertainty
  • Addresses treatment of measurement uncertainty in the group (notably for ISO 11201, ISO 11202 and ISO 11204).
• Use in noise test codes
  • Guides how to pick standards from the ISO 11200 group to create standardized noise test codes that specify mounting, operating conditions and location of work stations.

Applications and users

EN ISO 11200:2014 is practical for:

• Manufacturers declaring machine noise and preparing data for technical documentation
• Acoustic consultants and test laboratories performing standardized noise tests
• Standards committees and authors drafting noise test codes for machinery families
• Procurement and regulatory bodies comparing declared noise levels, verifying compliance, or specifying noise limits in contracts
• Engineers using emission data for noise control design or predicting noise exposure at specific positions

Practical uses include declaration and verification of noise emissions, product comparison, noise control engineering, and informed procurement.
