本文件包括旨在评估聚合物材料暴露于可变甲醇含量燃料时的性能的程序。包括:最坏情况燃料的确定；在测量实际测试样品的物理性质之前，在燃料中调节实际测试样品的程序；以及用于评价用于甲醇燃料的聚合物材料的测试方法。

This document consists of procedures which are designed to evaluate the performance of polymeric materials when they are exposed to variable methanol content fuels. Covered are: the determination of worst case fuel; the procedure for conditioning actual test specimens in fuel prior to measuring their physical properties; and test methods for evaluating polymeric materials for use in methanol fuels.
