BS EN 772-19:2000 PDF Download

This standard, BS EN 772-19:2000, specifies a method for determining the moisture expansion of large horizontally perforated clay masonry units. The standard focuses on measuring the length change of specimens when subjected to boiling water. The test method involves preparing test specimens of the clay masonry units, ensuring they meet certain dimensional requirements. These specimens are then immersed in boiling water for a specific period of time. The length change of the specimens is measured before and after the boiling water exposure to determine the moisture expansion. This standard provides guidance on the equipment, test conditions, and calculation methods necessary for accurately assessing the moisture expansion of these masonry units.
