Specification for an identification scheme for pipelines
This International Standard lays down the requirements for a scheme to indicate, by appropriate marking, the functions or contents of rigid pipe assemblies in aircraft and spacecraft systems, but excluding those in aero-engines with the exception of those which connect directly to the airframe systems at their break points.
These requirements may also be applied to hose assemblies, if desired.
The purpose of the scheme is to provide the minimum identification necessary for normal maintenance purposes.
NOTE – Markers used for the purpose of applying this identification scheme should not adversely affect the chemical or mechanical properties of the pipes or conduits.
