Recommendation of RILEM TC 274-TCE: test method to determine the apparent water vapor transfer coefficient of earthen materials
摘要
This recommendation paper is based on the work carried out within the RILEM Technical Committee TC 274-TCE concerning a test method to determine the apparent vapor transfer coefficient of earthen building products. The objective is to provide guidance on the methodology for performing wet cup measurements, in addition to the international standard EN ISO 12572 applied for earthen products, which is significantly affected by surface resistance, even when the test is conducted in a ventilated climatic chamber.
