Full title and description

Space systems — Fluid characteristics, sampling and test methods — Part 11: Ammonia. This part of ISO 15859 specifies characteristic requirements, sampling and test methods applicable to ammonia used in space systems and associated ground-support hardware and test facilities.

Abstract

ISO 15859-11:2004 defines properties, impurity limits, and recommended sampling and analytical test procedures for ammonia when it is handled, stored, transferred or evaluated for use in aerospace and space-system applications. The document is intended to promote interchangeability, safety and reliability of fluids used in spacecraft and related systems.

Scope

ISO 15859-11:2004 covers the defining characteristics, allowable impurity limits and the recommended methods for sampling and laboratory testing of ammonia used in spacecraft and associated ground hardware. It addresses requirements needed to ensure fluid quality for performance and safety in space-system environments, and should be used together with the other parts of ISO 15859 that cover other fluids.

Key topics and requirements

• Definition of fluid characteristics for ammonia in space-system use (physical properties and purity requirements).
• Specified impurity limits and acceptance criteria relevant to propulsion, thermal control, and support systems.
• Recommended procedures for representative sampling of bulk ammonia and transfer lines.
• Analytical and test methods for common contaminants and properties (composition, moisture, particulate contamination, etc.).
• Marking, handling and documentation practices to preserve sample integrity and traceability.

Typical use and users

Primary users are aerospace engineers, propellant/fluid quality laboratories, procurement and quality assurance personnel in spacecraft manufacturers, launch-service providers, space agencies, and contractors responsible for ground-support equipment. The standard is used when specifying fluid procurement, acceptance testing and when comparing or harmonizing national/specification requirements for ammonia in space applications.

Related standards

ISO 15859 is a multi-part series; related parts address other fluids such as oxygen, hydrogen, nitrogen, helium, nitrogen tetroxide, hydrazine, monomethylhydrazine, kerosene, argon, water, carbon dioxide and breathing air (other parts in the ISO 15859 series). National adoptions (for example BS ISO 15859-11:2004) provide localized publication records and purchasing information.
