摘要

1.1This test method is an adaptation of the German Standard DIN 53514, a further development of the former “Defo Test” (seeAppendix X1).1.2This test method is capable of measuring and characterizing the rheological behavior (viscosity and elasticity) of unvulcanized raw rubbers and rubber compounds, relating to the macro structure of rubber polymers (average molecular weight, molecular weight distribution, long chain branching, and micro- and macro-gel).1.3The viscosity and elasticity of unvulcanized rubbers and rubber compounds are determined by subjecting cylindrical test pieces to a compression/recovery cycle. The dependency on shear rate at constant shear stress is evaluated and the material fatigue behavior is determined in repeat cycle testing.1.4The non-Newtonian viscous and elastic behavior of rubbers and rubber compounds can also be evaluated.1.5Statistical evaluation of the test data provides an indication of data variation, which may be employed as an estimate of the homogeneity of the material tested.1.6The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.1.7This 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.1.8This 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 ======5.1The viscous and elastic behavior of unvulcanized rubbers and rubber compounds is of paramount importance in rubber manufacturing, since it affects processing, such as mixing, calendering, extrusion, and molding. The uniformity of these properties is equally important, as fluctuations will cause upsets in manufacturing processes.5.2A test capable of measuring viscosity and elasticity of unvulcanized rubbers and rubber compounds, including their uniformity and prediction of processing behavior, is therefore highly desirable (see PracticeD6048for further information).5.3Compared to many other rheological tests, this test method measures viscosity and elasticity related parameters under conditions of low shear and has a high discriminating power. It can detect small rheological differences. A full discussion of the principles behind stress relaxation testing is given in PracticeD6048.5.4Test results of this test method may be useful in predicting processability, but correlation with actual manufacturing processes must be established in each individual case, since conditions vary too widely.5.5This test method is suitable for specification compliance testing, quality control, referee purposes, and research and development work. 1.1该试验方法是对德国标准DIN 53514的改编，是对之前“Defo试验”的进一步发展（见附录X1).1.2本试验方法能够测量和表征未硫化生胶和橡胶化合物的流变行为（粘度和弹性），与橡胶聚合物的宏观结构（平均分子量、分子量分布、长链支化以及微观和宏观凝胶）有关。1.3未硫化橡胶和橡胶化合物的粘度和弹性是通过对圆柱形试样进行压缩/恢复循环来确定的。评估恒定剪切应力下剪切速率的依赖性，并在重复循环试验中确定材料疲劳行为。1.4还可以评估橡胶和橡胶化合物的非牛顿粘性和弹性行为。1.5测试数据的统计评估提供了数据变化的指示，可用于估计测试材料的均匀性。1.6以国际单位制表示的数值应视为标准。括号中的值仅供参考。1.7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。1.8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未硫化橡胶和橡胶化合物的粘性和弹性行为在橡胶制造中至关重要，因为它影响加工，如混合、压延、挤出和成型。这些特性的均匀性同样重要，因为波动会导致制造过程中的混乱。5.2因此，非常需要能够测量未硫化橡胶和橡胶化合物的粘度和弹性的测试，包括其均匀性和加工行为的预测（见实践）D6048更多信息）。5.3与许多其他流变测试相比，该测试方法在低剪切条件下测量粘度和弹性相关参数，具有较高的识别能力。它可以检测出微小的流变差异。在实践中充分讨论了应力松弛测试背后的原理D6048.5.4该测试方法的测试结果可能有助于预测加工性，但由于条件变化太大，必须在每种情况下建立与实际制造过程的相关性。5.5本测试方法适用于规范符合性测试、质量控制、仲裁目的以及研发工作。展开▼
