Oxygen System and Component Cleaning
|Publication Date:||1 June 2013|
This SAE Aerospace Recommended Practice (ARP) provides recommended practices for cleaning aircraft oxygen equipment such as tubing, pieces, parts (including regulator and valve parts), cylinders and ground-based equipment that may be used to support aircraft oxygen systems. This revision introduces a cleanliness coding scheme that can be referenced as a requirement, and/or referenced to identify compliance to meeting such a requirement. These methods may apply to gaseous and liquid oxygen equipment. This document specifies work area details, methods to select suitable cleaning agents, cleaning methods, test methods to verify cleanliness level, and methods of packaging the components and parts after cleaning. Technicians designated to clean oxygen equipment must be qualified and trained to clean oxygen equipment. This ARP is applicable to metallic and non-metallic parts.
The purpose of this document is to provide recommended methods to clean aircraft oxygen equipment and ground-based equipment to support aircraft oxygen systems. This document outlines minimum accepted practices to clean oxygen parts. It is intended that oxygen equipment cleaning operations perform to a minimum level that will be suitable to preclude toxic and fire hazards for the application and conditions the equipment will be exposed to.
