IGF::OT::IGF THE GOVERNMENT IS UNILATERALLY ORDERING SPECIAL STUDIES SERVICES IN ACCORDANCE WITH THE FOLLOWING CONTRACT CLAUSES FOR THE "NAFION-AMMONIA COMPATIBILITY TEST AND DATA COLLECTION STUDY": 1. B.5 SPECIAL STUDIES SERVICES IDIQ CLIN 003, 2. H.7 SPECIAL STUDIES TASK ORDERING PROCEDURES APPLICABLE TO CLIN 003 ONLY, AND 3. I.7 FAR 52.216-19 ORDER LIMITATIONS OCT 1995 APPLICABLE TO CLINS 002 AND 003. PERIOD OF PERFORMANCE OF THIS TASK ORDER IS AWARD DATE THROUGH DECEMBER 31, 2018. PERFORMANCE OF THIS TASK ORDER IS IN ACCORDANCE WITH THE TERMS AND CONDITIONS OF THE BASE CONTRACT NNK14MA75C. DESCRIPTION OF WORK: THE CONTRACTOR SHALL CONDUCT TESTING WITH NAFION BUNDLE ASSEMBLIES IN THE CST-100 HUMIDITY CONTROL SYSTEM (HCS) TO ASSESS NAFION DEGRADATION WHEN EXPOSED TO AMMONIA (NH3) REPRESENTATIVE OF THE FOLLOWING: TEST 1 NAFION CAPACITY AND HUMIDITY SENSITIVITY. CONDUCT TEST 1A UP TO MAXIMUM 900 LOADED HOURS. TEST 1B IS TO BE PERFORMED WITH REMAINING HOURS. BOTH TESTS (1A AND 1B) WILL ENCOMPASS UP TO A MAXIMUM OF 900 LOADED HOURS COMBINED. SHOULD TEST 1A USE THE MAXIMUM 900 LOADED HOURS, THEN TEST 1B IS NOT REQUIRED. TEST 1A NAFION CAPACITY ASSESS NAFION WATER REMOVAL RATE (WRR) BASED ON EXPOSURE TO ELEVATED CONCENTRATION OF NH3 TO DETERMINE THE CAPACITY OF THE BUNDLE TO PERFORM. CONCENTRATION SHALL BE DETERMINED BASED ON CONSIDERATIONS FROM FACTORS SUCH AS TEST DURATION, LABORATORY INSTRUMENTATION CAPABILITY, AND TEST PERSONNEL SAFETY. TEST 1B NH3 HUMIDITY SENSITIVITY. ASSESS NAFION WRR BASED ON OPERATIONAL EXPOSURE OF NH3 CONCENTRATION WITH MAXIMUM DEW POINT OF 10F. TEST 2 NH3 OPERATIONAL ASSESS HCS WRR BASED ON NOMINALLY AVAILABLE NH3 CONCENTRATION WITH HCS AND TCCS (TRACE CONTAMINANT CONTROL SUBASSEMBLY) PERFORMING NOMINALLY. TEST 3 NH3 NON-OPERATIONAL. ASSESS NAFION WRR BASED ON EXPOSURE TO AMBIENT LEVELS OF NH3. THE CONTRACTOR SHALL CONDUCT DESTRUCTIVE TESTING ON NAFION TUBE SAMPLES. THE CONTRACTOR SHALL DEVELOP A TEST PLAN SUBJECT TO NASA APPROVAL PRIOR TO TEST START. IN CONSIDERATION OF THE MODIFICATION AGREED TO HEREIN AS COMPLETE EQUITABLE ADJUSTMENT FOR CHANGES DESCRIBED ABOVE, THE CONTRACTOR HEREBY RELEASES THE GOVERNMENT FROM ANY AND ALL LIABILITY UNDER THIS CONTRACT FOR FURTHER EQUITABLE ADJUSTMENTS ATTRIBUTABLE TO SUCH FACTS OR CIRCUMSTANCES GIVING RISE TO THE PROPOSED ADJUSTMENT.
