本试验方法描述了测定纸板卷相对硬度均匀性的程序。由于目前有几种设备使用截然不同的技术来测定硬度，因此该方法仅适用于实际测量过程，而不适用于具体的测试设备。

This test method describes a procedure to determine the uniformity in relative hardness of rolls of containerboard. Since several devices are currently available that use significantly differing technologies to determine hardness, this method only addresses the actual measurement process and not the test equipment specifically.
