What is BS EN 61511-2:2011 ?

Title: Understanding BS EN 61511-2:2011 and BS EN 13139:2002

BS EN 61511-2:2011 and BS EN 13139:2002 are two important international standards that cater to different aspects of wind turbine technology and construction, respectively. Understanding these standards is crucial for manufacturers, developers, and regulatory authorities to ensure compliance with relevant regulations and guidelines. In this article, we will discuss the key requirements and specifications of BS EN 61511-2:2011 and BS EN 13139:2002.

BS EN 61511-2:2011: Understanding Noise Emissions and Assessing Environmental Impact

BS EN 61511-2:2011 is an international standard that provides guidelines for the design, installation, and maintenance of onshore and offshore wind turbines. The standard is divided into four parts, which cover various aspects of wind turbine technology. One of the four parts of BS EN 61511-2:2011 is dedicated to the measurement and assessment of noise emissions from wind turbines.

The main purpose of BS EN 61511-2:2011 is to ensure that wind turbines operate within acceptable noise limits, minimizing potential disturbance to nearby communities and wildlife. The standard provides detailed information on how to measure noise emissions and assess their significance based on location and time of day.

To measure noise emissions, BS EN 61511-2:2011 recommends using a sound level meter that is calibrated to the appropriate unit of measurement. The standard also recommends conducting measurements at the most representative points near the wind turbine, such as the centerline or the outer edge, to ensure accurate assessment of noise levels.

BS EN 13139:2002: Establishment of Uniform Testing Methods and Performance Criteria for Mortar

BS EN 13139:2002 is a technical standard that provides guidelines and specifications for the production and application of mortar intended for masonry construction. The standard was developed by the British Standards Institution (BSI) in collaboration with other European committees to ensure high-quality mortar that meets the necessary requirements for durability and performance.

The primary purpose of BS EN 13139:2002 is to establish uniform testing methods and performance criteria for mortar used in masonry construction. The standard outlines the procedures for testing mortar products, including the testing methods and criteria for compressive strength, adhesive strength, and durability.

BS EN 13139:2002 also provides guidelines for the production and packaging of mortar products. The standard specifies the materials and components that can be used in the production of mortar, as well as the requirements for the packaging and labeling of the products.

Conclusion:

BS EN 61511-2:2011 and BS EN 13139:2002 are two important international standards that cater to different aspects of wind turbine technology and construction. Understanding these standards is essential for manufacturers, developers, and regulatory authorities to ensure compliance with relevant regulations and guidelines. By following the guidelines and requirements outlined in these standards, manufacturers can ensure that their products are safe, reliable, and meet the necessary criteria for use in various applications.
