ISO 19004:2004描述了如何确定用于测量橡胶和橡胶制品典型物理和化学特性的试验方法的试验灵敏度。它也适用于测量炭黑填料性能的试验。测试灵敏度定义为测试方法对待测基本特性的分辨力与以标准偏差表示的测量误差之比。它通常被描述为“信噪比”。本标准未涉及测定极低或痕量成分水平时的阈值（即最低）检测限的灵敏度主题。经ASTM许可，ISO 19004:2004基于ASTM D 6600-00《橡胶试验方法测试灵敏度评估标准实施规程》，ASTM版权所有。

ISO 19004:2004 describes how test sensitivity can be determined for test methods used to measure typical physical and chemical properties of rubber and rubber products. It is also applicable to tests used to measure the properties of carbon black fillers.Test sensitivity is defined as the ratio of the discrimination power of a test method for the fundamental property to be determined to the measurement error expressed as a standard deviation. It is frequently described as the 'signal-to-noise ratio'.The standard does not address the topic of sensitivity in the context of threshold (i.e. minimum) detection limits in the determination of very low or trace constituent levels.ISO 19004:2004 is based, with permission of ASTM, on ASTM D 6600-00, Standard Practice for Evaluating Test Sensitivity for Rubber Test Methods, copyright ASTM.
