This qualification by similarity is applicable if the only difference between the previously qualified MIL-PRF-85045/18 cable and this MIL- PRF-85045/15 cable is the outer jacket mate
23、rial. If the MIL-PRF-85045/15 cable is identical to the previously qualified MIL-PRF-85045/18 cable, no testing is required for qualification. A certificate of compliance may be submitted in lieu of performing the acid generation, halogen content, toxicity index and fungus inspections. Testing may b
