ISO 15859-10:2004规定了水成分的限值，并确定了适用于水成分验证的取样和试验要求。 ISO 15859-10:2004仅适用于饮用水和高纯度软化水或去离子水，用于冷却和维修空间系统，以及HP（高纯度）和P（饮用水）型飞行硬件和地面维修、系统和设备。 它不适用于可能提供给空间系统的其他类型的水。ISO 15859-10:2004仅适用于本规范规定范围内的进水。 ISO 15859-10:2004适用于确保流体进入运载火箭或航天器时，流体成分符合下文规定的限值或为特定用途商定的任何技术规范所需的任何取样操作。

ISO 15859-10:2004 specifies limits for the composition of water and establishes the sampling and test requirements applicable for the verification of the water composition. ISO 15859-10:2004 is applicable to only potable water and high-purity demineralized or deionized water, used for cooling and servicing of space systems as well as both flight hardware and ground servicing, system, and equipment, of Type HP (high purity) and Type P [potable (drinking)]. It is not applicable to other types of water that may be provided to a space system. ISO 15859-10:2004 is applicable to influents only within the specified limits herein. ISO 15859-10:2004 is applicable to any sampling operation required to ensure that, when the fluid enters the launch vehicle or spacecraft, the fluid composition complies with the limits provided hereafter or with any technical specification agreed to for a particular use.
