SP21511 Laser Ablation for Metallic Surface Preparation
This standard contains the general requirements for the safe and effective use of portable or stationary, pulsed, laser ablation equipment, with fiber optic beam delivery to a hand-held, or automated, end effector that emits a scanned and focused laser beam, to prepare metallic surfaces, specifically limited to ferrous metals, for maintenance, repair, recoating, or lining.
SP21514 Dry Ice Blasting on Metallic and Nonmetallic Substrates
This standard contains the general requirements and best industry practice for the safe and effective use of dry ice blasting technology equipment for cleaning of metallic and nonmetallic surfaces prior to maintenance, repair, recoating, or to provide a clean, contaminant-free exposed surface. This standard will also contain information of dry ice media, basic safety requirements, and benefits of using this technology.
SP21523 Atmospheric Plasma Coating Removal and Surface Preparation
This standard contains the general requirements for the safe and effective use of portable non-thermal plasma technology equipment for coating removal and surface preparation of metallic and nonmetallic surfaces prior to maintenance, repair, recoating, or to provide a clean, contaminant-free exposed surface.
SP21528 Power Tool Cleaning of Non-Ferrous Metals, Stainless Steels, and Galvanized Steels
This standard contains the requirements for power-tool cleaning of non-ferrous metals, stainless steels, and galvanized steels to produce a bare metal surface. This standard represents a degree of cleaning similar to that defined for carbon steel substrates in SSPC-SP 11.
SP21538 High Pressure Water Cleaning Injecting With Inhibitor in Type C Tank
Surface preparation of type C liquid tank inside with no coat, normal method is grinding to St2/St3 grade with heavy dust and long cycle. New method can be de-rusting with high pressure water with corrosion inhibitor solution. The new standard shall require cleaning water pressure scope, corrosion inhibitor solution type, anti-rust mechanism, safety and harmless requirement of solution, and impact of welding.
