IEC 60268-5 Electroacoustics - Sound Level Meters - Performance Tests: Eurolabs Laboratory Testing Service

The IEC 60268-5 standard is a widely accepted international standard that governs the performance testing of sound level meters. This standard, developed by the International Electrotechnical Commission (IEC), provides guidelines for evaluating the accuracy and reliability of sound level meters used in various applications.

Legal and Regulatory Framework

The IEC 60268-5 standard is referenced in several national standards, including EN 61672-1:2013, ISO/TS 9001:2015, and ASTM E2536-15. Compliance with these standards is mandatory for manufacturers of sound level meters who wish to demonstrate their products conformity to international standards.

International and National Standards

IEC 60268-5:2009 was published in 2009 and has since been revised in 2020 (IEC 60268-5:2020). The standard covers the performance testing of sound level meters used for measuring sound levels in various environments, including workplaces, public spaces, and industrial settings.

Standard Development Organizations

The IEC is responsible for developing and maintaining international standards for electroacoustics. The IEC TC 29 (Electroacoustics) is responsible for overseeing the development of standards related to sound level meters.

Evolution of Standards

Standards evolve over time to reflect changes in technology, regulations, or industry practices. New revisions of standards are typically published every 5-10 years, incorporating updates and refinements based on new research, testing, and user feedback.

Standard Numbers and Scope

IEC 60268-5:2020 is the latest revision of this standard. The scope of the standard includes:

  • Performance testing of sound level meters

  • Measurement uncertainty and accuracy requirements

  • Frequency response and dynamic range specifications
