AD/EMY/20 requires specified RFD lifejackets made before March 1980 to undergo a pressure test at the next scheduled inspection: hold at 1400 mm water gauge for 5–10 minutes, then reduce to 305 mm for 5 minutes; after correcting for temperature the pressure must not be less than 275 mm. It applies to listed adult, crew and infant types and refers operators and maintenance organisations to the RFD overhaul manual and Service Bulletin 25-33 because of suspected polyurethane coating deterioration.
