本试验方法旨在确定涂漆或未涂漆纤维板在涉及折痕和弯曲的应用中的适用性。试验的具体目的是确定适当折痕的给定材料是否可以沿着压印折痕弯曲，而不会在弯曲表面出现令人不快的失效。

This test method is designed to determine the suitability of a painted or unpainted fiberboard for application involving creasing and bending. The specific purpose of the test is to determine whether a given material, properly creased, can be bent along the impressed crease without objectionable failure on the surface of the bend.
