1.范围1。1本试验方法在规定的溶剂和萃取时间条件下，测量纸、纸板和纸浆样品中石油蜡的含量。1.2窗帘涂层蜡中的某些成分可能不会溶解在指定的溶剂（甲乙酮）中，一些木材提取物可能会溶解在溶剂中。该方法不区分石油蜡和木材提取物，如果蜡中含有石油蜡以外的物质，则不打算测量整体蜡含量。1.3本试验方法并不旨在解决与其使用相关的所有安全问题（如有）。本试验方法的使用者有责任在使用前建立适当的安全和健康实践，并确定监管限制的适用性。1.4由于溶剂和萃取时间的不同，使用本方法获得的试验结果可能与ASTM D 590的试验结果不同。

1. Scope1.1 This test method measures the amount of petroleum wax in paper, paperboard, and pulp samples under specified conditions of solvent and extraction time.1.2 Some ingredients in curtain-coated wax may not be dissolved in the specified solvent (methyl ethyl ketone) and some wood extractives may be dissolved in the solvent. This method does not differentiate between petroleum wax and wood extractives and does not intend to measure the overall wax level if the wax contains substance other than petroleum wax.1.3 This test method does not purport to address all the safety problems, if any, associated with its use. It is the responsibility of the user of this test method to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.1.4 The test results obtained with this method may differ from that with ASTM D 590 due to the difference in the solvent and extraction time.
