JSMLT – The Basics
• A portable tool to aid the warfighter to determine leakage and fit of protective masks
– Used to maintain masks in a high state of readiness
– Reinforces a unit’s PMCS program
• Concept of Operations
– Garrison and deployed operations
– Peacetime, wartime, military operations other than war, garrison training and field exercises
– Shore and afloat forces
– Supports NBC capabilities in low, medium and high threat areas

JSMLT – Mask Leakage Testing
• Mask placed on the headform• Aerosol released under shroud over the protective mask
– Poly-Dispersed (0.2 - 0.5µ)
• Aerosol penetrates any existing leaks due to negative pressure applied under the mask
• Penetrating Aerosol Particles are Detected by Light Scattering Photometry
• Percent Penetration Is Calculated

JSMLT – Light Scattering Photometry
• The aerosol particles that have penetrated the mask pass into the light scattering chamber
• The particles scatter the light that passes through the intersection of the cones
• The PMT converts the scattered light into an electrical signal

JSMLT vs. Current Capabilities
(Trailer or fixed site)
Five devices currently required to determine function and fit – M14 Mask Leakage Tester
– M4A1 Outlet Valve Leakage Tester
– Q179 Drink Tube Air Flow Resistance Tester
– Q204 Drink Tube Assembly Leakage Tester
– M41 Protection Assessment Test SystemOnly deployable system on listCannot identify defective or unserviceable components

Joint Program Executive Office for Chemical and Biological Defense
JSMLT vs. Current Capabilities• Current Mask Testing Efforts
– Mask Serviceability• Visual Inspection• Qualitative, Low accuracy, Low precision
– Fit Testing• Qualitative Methods
– Negative Pressure Check
• Quantitative Method– M41 PATS (Not widely used by USAF and USMC)
– Current surveillance efforts• Continue to identify a large percentage of critical defects• Cannot conduct 100% inspections
• Bottom Line: JSMLT significantly improves ability to detect and repair critical leaks in protective masks– >50% not identified through visual inspection– 4.5% not identified in JSMLT operational testing

JSMLT – Benefit to the Warfighter
• Issues with Mask Readiness Have Persisted– Leaking Facepieces– Torn/Dirty Outlet Valve Disks– Incorrectly Installed/Damaged Voicemitters– Damaged Drink Systems
• Preventative Maintenance, Checks, and Services (PMCS) Alone Are Insufficient
• JSMLT Will Provide the Warfighter with a Means of Verifying PMCS Has Been Performed Correctly
• Services that Will Use the JSMLT:– U.S. Marine Corps– U.S. Navy– U.S. Air Force– U.S. Coast Guard (DHS)
