Non-ODC
Oxygen Line Cleaning
Project Number: J-99-CL-015
Joint Test Protocol
The objective of the Non-ODC Oxygen Line Cleaning JG-PP project is to identify and validate one or more technologies using ODC to clean oxygen lines on DoD and NASA aerospace vehicles. Chlorofluorocarbons (specifically CFC-113) and hydrochlorofluorocarbons (specifically HCFC-141b) were identified as the target HazMats to be eliminated or reduced. These chemicals are known stratospheric ozone-depleters. They are used to flush clean the insides of oxygen lines and equipment used in aerospace vehicles, surface ships, and submarines. The lines may be constructed of aluminum, stainless steel, or copper.A joint group led by JG-PP and consisting of technical representatives from OC-ALC, NASA, NAVAIR, Northrop-Grumman, B-1, B-2, F-15, F-16 weapon systems, and Versar Inc. identified engineering performance criteria for oxygen line cleaning onboard and off aerospace vehicles. This group reached consensus on the test conditions and acceptance criteria to qualify alternatives against these critical technical and performance requirements. This JTP contains the critical requirements and tests defined by this technical community to qualify non-ODC cleaners for aerospace vehicle oxygen systems. The testing criteria are listed below:
- Onboard Oxygen Line Cleaning
System
- LOX Impact Neat Chemical Test
- Materials Compatibility with Cleaning Solvent Surfactant Mixture
- Nonvolatile Residue Test
- Moisture Test
- Cleanliness Verification Test
- Functional Test
- Component/Model/System Replica Test
- Dead Areas Test
- Leak Testing
- Hazard Analysis
- Off-Aircraft Oxygen Line
Cleaning System
- Nonvolatile Residue Test
- Soil Removal
- Particle Content
- Water Content.
The critical requirements and tests definitions are contained in this JTP. To view the JTP for Validation of Alternatives to Ozone Depleting Chemicals Used in Oxygen Line Cleaning, dated July 24, 2001, please click here.
