Title: Understanding BS EN 61216:2011 and BS EN 13139:2002

BS EN 61216:2011 and BS EN 13139:2002 are two important international standards that cater to different aspects of wind turbine technology and construction, respectively. In this article, we will provide an overview of what these standards are, their purpose, and the key requirements and specifications they provide.

What is BS EN 61216:2011?

BS EN 61216:2011 is an international standard that outlines the criteria and procedures for determining noise emissions from wind turbines. It is part of the BS EN 61400 series, which covers various aspects of wind turbine technology. The main purpose of BS EN 61216:2011 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. It allows developers and manufacturers to design wind turbine installations in compliance with local noise regulations and ensure sustainable development of wind energy projects.

Key Requirements of BS EN 61216:2011

To ensure that wind turbines operate within acceptable noise limits, BS EN 61216:2011 lays down criteria and procedures for determining noise levels and evaluating their potential environmental impact. The standard provides the following key requirements:

Noise Measurement: Developers and manufacturers must measure the noise emissions from their wind turbines and use the results to evaluate their potential environmental impact.

Noise Modeling: Developers and manufacturers must use noise modeling software to simulate the noise emissions from their wind turbines and evaluate their impact on the environment.

Environmental Impact Assessment: Developers and manufacturers must conduct an environmental impact assessment to determine the potential environmental impact of their wind turbines and ensure that their designs comply with environmental regulations.

Noise Management: Developers and manufacturers must implement noise management measures to reduce the noise emissions from their wind turbines and minimize their potential environmental impact.

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, with the aim of ensuring 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. 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

To ensure the quality of their mortar products, manufacturers must follow the key requirements and specifications outlined in BS EN 13139:200These requirements and specifications include:

Composition: Mortar must be made of appropriate materials to ensure its durability and performance.

Consistency: Mortar must be consistent in terms of its physical, chemical, and microstructure characteristics.

Workability: Mortar must be workable, meaning it can be shaped and molded into different shapes and sizes without breaking or losing its integrity.

Adhesive strength: Mortar must have an adhesive strength that allows it to bond well with other materials.

Durability: Mortar must be able to withstand the effects of weathering, aging, and other factors that can affect its performance.

Conclusion:

BS EN 61216:2011 and BS EN 13139:2002 are important international standards that cater to different aspects of.
