1.1当通过两个柴油喷射器装置程序中的任何一个进行评估时，这些试验方法测量含聚合物液体在100°C下的粘度损失百分比。程序A使用欧洲柴油喷射器测试设备，程序B使用喷油器剪切稳定性测试（FISST）设备。粘度损失反映了由于喷嘴处的剪切而导致的聚合物降解。 注1-ASTM试验方法 D2603 已用于该物业的类似评估。它有许多与重要性声明中指出的相同的局限性。尚未对声波法和柴油喷射器法的结果进行详细关联。试验方法D2603不再提供设备和更换零件。注2-本方法的程序A使用CEC L中定义的试验装置- 14-A-79、IP 294/76和DIN 51382。操作程序在四个具体点上有所不同。程序A在30个循环下评估液压型流体，在100°C下测量粘度。报告了单次测定的结果。没有使用设备严重性校正系数来调整结果。 1.2本标准无意解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。

1.1 These test methods measure the percent viscosity loss at 100°C of polymer-containing fluids when evaluated by either of two diesel injector apparatus procedures. Procedure A uses European Diesel Injector Test Equipment and Procedure B uses Fuel Injector Shear Stability Test (FISST) equipment. The viscosity loss reflects polymer degradation due to shear at the nozzle. Note 1-ASTM Test Method D2603 has been used for similar evaluation of this property. It has many of the same limitations as indicated in the significance statement. No detailed attempt has been undertaken to correlate the results by the sonic and the diesel injector methods. Equipment and replacement parts are no longer available for Test Method D2603. Note 2-Procedure A of this method uses test apparatus as defined in CEC L-14-A-79, IP 294/76 and DIN 51382. The operational procedure is different on four specific points. Procedure A evaluates hydraulic-type fluids at 30 cycles, with viscosities measured at 100°C. Results are reported for single determinations. No equipment severity correction factor is used to adjust results. 1.2 This standard does not purport to address all of the safety problems, 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.
