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.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 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.
1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the specification.
1.3 The following precautionary statement pertains to the test method portion only, Section This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. , of this specification: Specific precautionary statements are given in .
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
