本欧洲标准规定了通过力延性试验确定未老化，老化，残余或回收的沥青粘合剂，特别是聚合物改性沥青的拉伸性能的方法。 强力延性试验期间完成的工作是评估这些材料质量的标准。 警告 - 使用本欧洲标准可能涉及危险材料，操作和设备。本欧洲标准不旨在解决与其使用相关的所有安全问题。本欧洲标准的用户有责任建立适当的安全和健康实践，并在使用前确定法规限制的适用性

This European Standard specifies a method for determining the tensile properties of an unaged, aged, residual or recovered bituminous binder, in particular those of polymer-modified bitumens by means of a force ductility test. The work done during the force ductility test is a criterion for assessing the quality of these materials. WARNING - The use of this European Standard may involve hazardous materials, operations and equipment. This European Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this European Standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
