ASTM F1460-93(1999)
(Practice)Standard Practice for Calibrating Oil Spill Dispersant Application Equipment Boom and Nozzle Systems
Standard Practice for Calibrating Oil Spill Dispersant Application Equipment Boom and Nozzle Systems
SCOPE
1.1 This practice covers uniform procedures for determining and reporting the dosage rate of oil spill dispersant application equipment.
1.2 This practice is applicable to spray systems employing booms and nozzles and is not fully applicable to other systems such as fire monitors, sonic distributors, or fan-spray guns.
1.3 This practice is applicable to systems for use on ships or boats and helicopters or airplanes.
1.4 This practice is one of four related to dispersant application systems. One is on design, one on calibration, one on deposition, and one on the use of the systems. Familiarity with all four standards is recommended. The other three standards are listed in Section 2.
1.5 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
