BS EN 29048:1991 PDF Download

The BS EN 29048:1991 standard focuses on assessing the extrudability of sealants used in building construction. This standard is applicable to both one-component and multi-component sealants, regardless of their packaging and application methods.

The purpose of this standard is to provide a standardized method for evaluating the ability of sealants to be extruded from their packages and applied to joints in buildings. It aims to ensure that sealants can be easily dispensed and accurately applied, contributing to efficient and effective construction practices.

The assessment of extrudability is conducted using standardized apparatus specified in the standard. The test evaluates the ability of sealants to be extruded under controlled conditions and assesses factors such as viscosity, flow rate, and ease of application. By establishing consistent criteria for extrudability, this standard helps ensure the quality and performance of sealants in building construction projects.
