What is BS EN 352-6-2002 ?

Title: Understanding BS EN 352-6-2002: A Technical Standard for Mortar in Masonry Construction

Building construction is an essential aspect of our society, and the use of mortar in masonry construction is critical to ensure the durability and stability of buildings. To ensure that the mortar products used in construction meet the necessary requirements for durability and performance, a technical standard like BS EN 352-6-2002 was developed by the British Standards Institution (BSI) in collaboration with other European committees. In this article, we will discuss the purpose of BS EN 352-6-2002, its key requirements and specifications, and how it compares to other fire safety regulations.

Purpose of BS EN 352-6-2002:

The primary purpose of BS EN 352-6-2002 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. The standard covers various aspects of mortar quality, including composition, consistency, workability, adhesive strength, compressive strength, and durability.

Key Requirements and Specifications:

BS EN 352-6-2002 provides a comprehensive framework for evaluating the quality of mortar products. The standard outlines key requirements and specifications that manufacturers must meet to ensure that their products are suitable for use in masonry construction. These requirements and specifications include the following:

Composition: Mortar must be made of at least 75% cement, 10% sand, and 15% additives. The sand and additives must also meet specific requirements for size, fine-ness, and distribution.

Consistency: Mortar must be consistent in terms of color, appearance, and consistency throughout the product.

Workability: Mortar must be able to flow and bond well with the masonry material.

Adhesive strength: Mortar must have an adhesive strength of at least 20MPa.

Compressive strength: Mortar must have a compressive strength of at least 15MPa.

Durability: Mortar must be able to withstand the effects of weathering, water, and other environmental factors for an extended period.

Fire resistance: Mortar must meet fire safety regulations, including the spread of fire and smoke.

Impact resistance: Mortar must be able to withstand impact from other objects without breaking.

Air and water resistance: Mortar must be able to withstand exposure to air and water without losing its consistency or strength.

Microstructure: Mortar must not contain any defects or flaws that could affect its performance or durability.

Comparing BS EN 352-6-2002 to Other Fire Safety Regulations:

While BS EN 352-6-2002 is an important technical standard for mortar in masonry construction, it is not the only standard that is relevant to fire safety regulations. Many countries have adopted updated standards, such as EN 1634-1, which provides a unified approach to fire resistance testing across Europe. These newer standards often take into account the latest scientific knowledge and technological advancements, offering a more comprehensive framework for evaluating the performance of door and shutter assemblies.

While BS EN 352-6-2002 may be considered outdated in some aspects, it still holds value in certain contexts. In regions where it is mandated by local building codes or specified in contractual agreements, compliance with BS EN 352-6-2002 is necessary. Additionally, some manufacturers may choose to test their products against this standard to cater to specific markets or maintain compatibility with existing installations.

However, as architects, specifiers, and regulatory bodies increasingly turn towards newer standards that offer a more comprehensive and internationally recognized approach to fire resistance testing, the relevance of BS EN 352-6-2002 may be called into question. These updated standards provide a broader scope, including the evaluation of factors like heat insulation, integrity, and radiation. Therefore, it is essential to consider the specific requirements and specifications of the project when choosing a mortar standard for use in masonry construction.
