Title: Understanding BS EN 15662: 2011 and BS EN 13139: 2002

BS EN 15662: 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 15662: 2011?

BS EN 15662: 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 and focuses on 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.

BS EN 15662: 2011 sets out the following key requirements:

Noise Measurement: Developers and manufacturers must measure the noise emissions from their wind turbines and provide the results in a specified format.

Evaluation of Noise Emissions: Developers and manufacturers must evaluate the potential environmental impact of their wind turbine installations based on the noise measurements.

Compliance: Developers and manufacturers must ensure that their wind turbine installations comply with the noise regulations in their respective countries or regions.

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. The standard was developed by the British Standards Institution (BSI) in collaboration with other European committees and aims to establish uniform testing methods and performance criteria for mortar used in masonry construction.

BS EN 13139: 2002 outlines the following key requirements and specifications:

Composition: Mortar must be composed of at least 75% cement, 10% sand, and 15% additives, such as water, cement, or sand.

Consistency: Mortar must be consistent in terms of color, texture, and finish.

Workability: Mortar must be workable and able to flow freely without leaving voids or irregularities in the mortar layer.

Adhesive Strength: Mortar must have an adhesive strength of at least 10MPa (measured on a 28-day exposure at 20°C).

Durability: Mortar must be able to withstand the effects of weathering, including water, rain, and atmospheric conditions, for an extended period.

Conclusion:

BS EN 15662: 2011 and BS EN 13139: 2002 are essential international standards for ensuring compliance with relevant regulations and requirements. Developers, manufacturers, and regulatory authorities must familiarize themselves with these standards to minimize potential disturbance to nearby communities and wildlife, and ensure sustainable development of wind energy projects.
