1.1本试验方法通常称为Mack T-8。本试验方法涵盖了评估柴油机油性能特性的发动机试验程序，包括粘度增加和烟尘浓度（负载）。 1.2本试验方法还提供了进行加长T-8试验的程序，该试验通常被称为T-8E。除附录A8中特别列出的项目外，T-8E的程序与T-8相同。此外，附录A8中列出的程序修改参考T- 8程序。 1.3以国际单位制或英寸-磅单位表示的数值应单独视为标准。在文本中，英寸-磅单位显示在括号中。 1.4本标准无意解决与其使用相关的所有安全问题（如有）。本标准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。具体安全注意事项见附录A5。

1.1 This test method is commonly referred to as the Mack T-8. This test method covers an engine test procedure for evaluating diesel engine oils for performance characteristics, including viscosity increase and soot concentrations (loading). 1.2 This test method also provides the procedure for running an extended length T-8 test, which is commonly referred to as the T-8E. The procedure for the T-8E is identical to the T-8 with the exception of the items specifically listed in Annex A8. Additionally, the procedure modifications listed in Annex A8 refer to the corresponding section of the T-8 procedure. 1.3 The values stated in either SI or inch-pound units are to be regarded separately as the standard. Within the text, the inch-pound units are shown in parentheses. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. See Annex A5 for specific safety precautions.
