本欧洲标准规定了与单面（OC）渲染灰浆的给定背景的兼容性的评估的测试方法。评估基于在暴露于耐候性循环之后测定施加在被测基材上的硬化后的粘合强度和透水性

This European Standard specifies a test method for the evaluation of the compatibility with given backgrounds of One-Coat (OC) rendering mortars. The evaluation is based on the determination of the adhesion strength and water permeability of the hardened render applied on tested substrates, after exposure to weathering cycles.
