(Specification)Standard Specification for Fabricated or Cast Automatic Self-Cleaning, Fuel Oil and Lubricating Oil Strainers
Standard Specification for Fabricated or Cast Automatic Self-Cleaning, Fuel Oil and Lubricating Oil Strainers
ABSTRACT
This specification covers the material, operating, and testing requirements for automatic or continuously self-cleaning strainers, or both, for use in fuel oil and lubricating oil systems and in any marine environment. The strainer may be either hydraulic, electric, or pneumatic operated, and is designed to operate under positive pressure, that is, on the discharge side of the pump. The strainers should operate at specified pressures, temperatures, shipboard environments, and self-cleaning rates. They shall also undergo flow capacity test, inclined flow capacity test, strength of internals test, and self-cleaning and filtration efficiency test.
SCOPE
1.1 This specification covers automatic or continuously self-cleaning automatic strainers, or both, for use in fuel and lubrication oil systems. The strainer is designed to operate under positive pressure (discharge side of the pump). Strainers manufactured to this specification are suitable for use in any marine environment.
1.2 It is not the intent of this document to redefine existing filtration standards. The intent is to provide sound guidelines for purchasers and designers of lube oil and fuel oil systems. Nominal micron requirements and filter efficiencies shall be as agreed upon by the purchaser and manufacturer and stated in the purchase order document.
1.3 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.
