Anotace

This specification covers requirements for pneumatic rotary descaling machines for removal of paint, rust, scale, nonskid deck covering and other coatings from steel and aluminum structures. These portable machines are intended for use in a marine environment, subject to salt air and spray during use and high humidity during storage. De scaling machines are available in two types and two classes, as follows: Type 1 which is the hand-held and Type 2 which is the deck-supported type. Both types have two classes which are Class A in inch-pound design and Class B in SI metric design. Hubs for use with descaling machines are also available in four classes: Class A is a hub that is non-metallic, nonwoven and non-contaminating, Class B is a peening hub for aluminum surfaces, Class C is a hub of metallic hammer type used for steel surfaces and Class D is a hub of metallic cutter type use for steel surfaces. A service life test shall be conducted on an uncoated steel test plate and each hub shall be subjected to a performance test.
