What is BS EN 61221:2011 ?

Title: Understanding BS EN 61221:2011 and BS EN 13139:2002

BS EN 61221:2011 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 requirements.

What is BS EN 61221:2011?

BS EN 61221:2011 is an international standard that outlines the procedures for the measurement and assessment of noise emissions from wind turbines. It is part of the BS EN 61400 series, which covers various aspects of wind turbine technology. This standard provides detailed information on how to measure noise emissions and assess their significance based on location and time of day.

The main purpose of BS EN 61221:2011 is to ensure that wind turbines operate within acceptable noise limits, minimizing potential disturbance to nearby communities and wildlife. The standard provides criteria and procedures for determining noise levels and evaluating their potential environmental impact.

Key Requirements of BS EN 61221:2011

To ensure compliance with BS EN 61221:2011, manufacturers must maintain records of noise measurements and assessments, as well as evaluate the potential environmental impact of their products. They must also ensure that their products meet the relevant noise regulations and guidelines.

What is BS EN 13139:2002?

BS EN 13139:2002 is a technical standard that provides guidelines and specifications for the production and application of mortar intended for masonry construction. This standard was developed by the British Standards Institution (BSI) in collaboration with other European committees to establish uniform testing methods and performance criteria for mortar used in masonry construction.

The primary purpose of BS EN 13139:2002 is to establish uniform testing methods and performance criteria for mortar used in masonry construction. By following this standard, manufacturers can ensure that their mortar products comply with industry requirements and are safe for use in various building applications.

Key Requirements and Specifications

BS EN 13139:2002 provides a comprehensive set of requirements for the quality and performance of mortar. The standard outlines the testing methods and criteria for evaluating the suitability of mortar for different applications, such as load-bearing walls, floors, and roofs.

The standard also specifies the physical properties and performance characteristics of mortar, such as compressive strength, tensile strength, and water resistance. It also provides guidelines for the production and packaging of mortar products.

Conclusion:

BS EN 61221:2011 and BS EN 13139:2002 are 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 requirements. By maintaining records of noise measurements and assessments, evaluating the potential environmental impact of their products, and ensuring that their products meet the relevant standards, manufacturers can ensure that their wind turbine installations are in compliance with BS EN 61221:2011 and BS EN 13139:2002.
