In practice buoyancy aids far exceed a 3-year service life expectancy, and can be tested for buoyancy using a weight. The other issues are damage, stitching and wear. Buoyancy aid and personal flotation devices need regular and routine inspection of any belts, stitching and other parts.
Personal flotation devices being worn on a navy transport . A personal flotation device (PFD; also referred to as a life jacket, life preserver, life belt, Mae West, life vest, life saver, cork jacket, buoyancy aid or flotation suit) is a flotation device in the form of a vest or suit that is worn by a user to prevent the wearer from drowning in a body of water.
National safety standards such as BS EN 13138-3:2007 in the United Kingdom require inflatable armbands to conform to certain standards, like puncture resistance and the level of buoyancy retained after a period of time beyond the inflation valve being opened and left open. This is an assessment of the efficiency of non-return valves designed to ...

A lifebuoy or life ring, among many other names (see § Other names), is a life-saving buoy designed to be thrown to a person in water to provide buoyancy and prevent drowning. [1] Some modern lifebuoys are fitted with one or more seawater-activated lights to aid rescue at night.
An extra low-pressure feed from the regulator first-stage lets the lifejacket be controlled as a buoyancy aid. This invention in 1971 of the "direct system," [citation needed] by ScubaPro, resulted in what was called a stabilizer jacket or stab jacket, and is now increasingly known as a buoyancy compensator (device), or simply "BCD". [citation ...

The buoyancy compensator is intended to control buoyancy of a diver and their personal diving equipment, including stage and bailout cylinders, and for minor additional equipment such as reels, cameras and instruments that are lightweight or near neutral buoyancy. It is not a buoyant lifting device for heavy tools and equipment.
