ActiveTest methods for building sheets for waterproofing - Part 12: Bitumen sheets for waterproofing-dimensional stability
建筑防水卷材试验方法 第12部分：沥青防水卷材 尺寸稳定性
Application Summary AI generated
This standard specifies the test method for determining the dimensional stability of bitumen sheets used for waterproofing in building construction. It is applied to evaluate how these sheets behave under thermal stress, ensuring they maintain their dimensions when exposed to temperature changes. The test is critical for quality control in manufacturing and for selecting materials for roofing and underground waterproofing applications.
