标准范围

ISO 15859-3:2004规定了氮成分的限值，并确定了适用于验证氮成分的取样和试验要求。ISO 15859-3:2004适用于飞行硬件和地面设施、系统和设备中使用的以下类型和等级的氮气:I型气态（A级:吹扫/加压，B级:机组呼吸，C级，F级，J级）和II型液体（A级:吹扫/加压，B级:机组呼吸，C级，F级）。ISO 15859-3:2004仅适用于规定范围内的进水。ISO 15859-3:2004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 15859-3:2004 specifies limits for the composition of nitrogen and establishes the sampling and test requirements applicable for the verification of nitrogen composition.ISO 15859-3:2004 is applicable to nitrogen, used in both flight hardware and ground facilities, systems and equipment, of the following types and grades of nitrogen: Type I, gaseous (Grade A: purging/pressurizing, Grade B: crew breathing, Grade C, Grade F, Grade J) and Type II, liquid (Grade A: purging/pressurizing, Grade B: crew breathing, Grade C, Grade F).ISO 15859-3:2004 is applicable to influents only within the specified limits.ISO 15859-3:2004 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.
