Abstract:

ONE HUNDRED AND ONE IGNITERS WERE FUNCTIONED IMMEDIATELY AFTER REMOVAL FROM THE SEALED CANS. All 85 igniters from Lot PA-67-3 and 15 igniters from Lot PA-67-1, functioned with a small delay. The other igniter from Lot PA-67-1 failed to ignite the illuminant. Another group of igniters were conditioned to 120 F and 95 humidity from 6 to 72 hours. All igniters functioned after 24 hours of conditioning. At the end of 48 hours of conditioning 3 igniters from Lot PA-19-1 functioned, all other igniters failed. Another group of 18 igniters from Lot PA-67-2 and 6 igniters from Lot PA-19-1 were coated with an epoxy resin and placed in phenolic engine cases before subjecting them to 120 F and 95 humidity. Six igniters from Lot PA-67-2 were functioned after 48 hours and 96 hours the remaining igniters functioned normally after 192 hours of conditioning. The epoxy coated igniters are recommended for use where there are high humidity conditions. Author
