1.1 本试验方法为Forschungstelle für Záhnräder und Getriebebau（齿轮和变速箱研究现场）目视法，通常称为FZG目视法，旨在测量用于润滑硬化钢齿轮的油的胶合负载能力。划痕是一种磨粒磨损形式，也是本试验方法中的失效标准。它主要用于评估经过温和添加剂处理的油（如工业齿轮油、变速箱油和液压油）的抗擦伤性。高EP型油，例如，符合API GL-4和GL-5要求的油，通常超过试验台的容量，因此，无法用该试验方法进行区分。 1.2 以国际单位制表示的数值应视为标准值。 本标准不包括其他计量单位。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 有关具体安全信息，请参阅第节 7. 部分 8. , 9.2 , 9.3.1 和 附件A1 . 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 许多汽车和工业应用中的动力传输是通过使用齿轮传动系统实现的。在较高的运行速度下，众所周知，润滑剂/添加剂系统是防止齿轮磨损（粘着磨损）的重要因素。本试验方法用于筛选用于润滑正齿轮和螺旋（平行轴）齿轮装置的油的胶合负载能力。 5.2 试验方法受到设备（试验台和齿轮）能力的限制，观察到的性能可能与在准双曲面齿轮装置上观察到的螺旋锥的胶合性能没有直接关系。它也仅限于区分含有温和极压添加剂或更少极压添加剂的油。含有较高添加剂的润滑剂，即符合API GL4或GL5要求的润滑剂，通常超过试验台的最大负载能力，因此，无法通过本试验方法区分其胶合能力。

1.1 This test method, the Forschungstelle für Záhnräder und Getriebebau (Research Site for Gears and Transmissions) Visual Method, commonly referred to as the FZG Visual Method, is intended to measure the scuffing load capacity of oils used to lubricate hardened steel gears. Scoring, a form of abrasive wear, is also included as a failure criteria in this test method. It is primarily used to assess the resistance to scuffing of mild additive treated oils such as industrial gear oils, transmission fluids, and hydraulic fluids. High EP type oils, for example, those oils meeting the requirements of API GL-4 and GL-5, generally exceed the capacity of the test rig and, therefore, cannot be differentiated with this test method. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific safety information, see Section 7 , Section 8 , 9.2 , 9.3.1 , and Annex A1 . 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 The transmission of power in many automotive and industrial applications is accomplished through the use of geared systems. At higher operating speeds it is well known that the lubricant/additive system can be a significant factor in preventing scuffing (adhesive wear) damage to gears. This test method is used to screen the scuffing load capacity of oils used to lubricate spur and helical (parallel axis) gear units. 5.2 The test method is limited by the capabilities of the equipment (test rig and gears), and the performance observed may not directly relate to scuffing performance observed with spiral bevel on hypoid gearing. It is also limited to discriminating between oils with mild EP additives or less. Lubricants containing higher levels of additives, that is, those meeting the requirements of API GL4 or GL5, generally exceed the maximum load capacity of the test rig and, therefore, cannot be distinguished for their scuffing capabilities by this test method.
