What is EN ISO 11681-7:2016?

EN ISO 11681-7:2016 is a technical standard that provides guidelines and requirements for the measurement of airborne noise emitted by machinery. It is part of the ISO 11681 series, which aims to harmonize noise emission measurements and provide accurate data for comparison of machinery noise levels.

Scope and Purpose

The scope of EN ISO 11681-7:2016 covers machinery designed for various purposes such as manufacturing, construction, agriculture, and transportation. The purpose of this standard is to specify the procedures and instrumentation required to measure the sound power levels of machinery under specific operating conditions.

By following the guidelines set out in EN ISO 11681-7:2016, manufacturers can ensure that the noise emitted by their machinery is within acceptable limits, providing a safer and healthier working environment for operators and nearby individuals. This standard also aids in reducing noise pollution and its impact on the surrounding community.

Measurement Procedures

EN ISO 11681-7:2016 specifies the methods and conditions for measuring the sound power level of machinery. It provides detailed instructions on the measurement setup, microphone positioning, background noise assessment, and the calculation of sound power levels based on the measured data.

One of the key aspects of this standard is the determination of the operating conditions during testing. It defines the reference operating conditions, which represent typical use cases for the machinery being tested. These reference conditions ensure that the test results are relevant and representative of real-world scenarios.

Moreover, EN ISO 11681-7:2016 outlines the requirements for the accuracy and calibration of the measurement equipment used. This ensures that the measurement results are reliable and can be compared across different testing facilities.

Benefits and Compliance

Compliance with EN ISO 11681-7:2016 offers several benefits to manufacturers. Firstly, it enables them to demonstrate the compliance of their machinery with noise emission regulations and standards. This is particularly important in industries where noise control is critical for worker safety and environmental considerations.

Furthermore, compliance with this standard allows manufacturers to benchmark their machinery against competitors' products, enabling them to identify areas for improvement in terms of noise reduction and overall product quality.

In conclusion, EN ISO 11681-7:2016 provides clear guidelines for measuring the airborne noise emitted by machinery. By adhering to these guidelines, manufacturers can ensure compliance with noise emission regulations, improve the working environment for operators, and reduce the impact of noise pollution on surrounding communities.
