IEC 61672-3 Electroacoustics - Sound Level Meters - Part 3: Periodic Tests

Comprehensive Guide to IEC 61672-3 Electroacoustics - Sound Level Meters - Part 3: Periodic Tests Laboratory Testing Service Provided by Eurolab

IEC 61672-3 is an international standard that outlines the requirements for sound level meters, specifically addressing periodic tests. The standard is developed and maintained by IEC Technical Committee 29 (TC 29) on Electroacoustics.

The standard is based on the principles of the ISO/IEC Directives, which provide guidance on the preparation and publication of international standards. The standard is available in several languages, including English, French, German, Spanish, Italian, and others.

Legal and Regulatory Framework

The use of sound level meters is regulated by various laws and regulations worldwide. In Europe, for example, the EU Machinery Directive (2006/42/EC) requires manufacturers to ensure that their products comply with the essential health and safety requirements. The directive also specifies that sound level meters must be designed and constructed in accordance with IEC 61672-3.

In other regions, such as North America, the Occupational Safety and Health Administration (OSHA) regulates the use of sound level meters in workplaces under the OSHA Noise Standard (29 CFR 1910.95). Similar regulations apply in Australia, Japan, and other countries.

International and National Standards

IEC 61672-3 is a consensus standard developed by experts from around the world through a collaborative process involving national committees, technical committees, and working groups. The standard is published annually, with updates incorporating new research findings, technological advancements, and regulatory changes.

National standards bodies, such as those in the United States (ANSI), Canada (CSA), and Germany (DIN), also develop and publish standards related to sound level meters. These national standards are often based on IEC 61672-3 or incorporate its requirements.

Standard Development Organizations

The International Electrotechnical Commission (IEC) is a non-profit, independent organization that develops and publishes international standards for the benefit of humanity. The IEC has 82 member countries and works with over 20,000 experts from industry, academia, and government to develop standards.

Other standard development organizations involved in sound level meters include:

How Standards Evolve and Get Updated

Standards evolve through a collaborative process involving industry experts, researchers, and stakeholders. New research findings, technological advancements, and regulatory changes are incorporated into the standard through regular updates.

IEC TC 29, for example, has published several revisions to IEC 61672-3 in recent years, incorporating new requirements for sound level meters used in various industries, such as construction, transportation, and healthcare.
