5.1 Excessive amounts of sodium can indicate the presence of materials that cause high wear of burner pumps and valves, and contribute to deposits of boiler heating surfaces.1.1 This test method covers the determination of sodium in residual fuel oil by means of a flame photometer. Its precision in low ranges limits its application to samples containing more than 15 mg/kg sodium. Other elements commonly found in residual fuel oil do not interfere.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.3 This standard does not purport to address all of the safety problems 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. For specific hazard statements see 7.3, 7.5, 7.7, 9.2, 7.8, 7.9, and Note 3.1.4 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.

5.1 Horizontal metal surfaces, on which water droplets tend to be retained, are more prone to rusting and corrosion than vertical or sloping surfaces. This test method is therefore more discriminating than Test Method D665 (Procedure A), since it gives a separate evaluation of the oil on a horizontal and a vertical surface. The test method indicates the ability of oils to prevent rusting and corrosion of all ferrous surfaces in steam turbines under full flow and quasi-static conditions. It is used for specification of new oils.1.1 This test method covers the ability of steam-turbine oils to prevent the rusting of horizontal and vertical ferrous surfaces when water becomes mixed with the oil.1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.1.3 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.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.

5.1 Boom sections are frequently combined into assemblages hundreds of meters in length prior to towing through the water to a spill site. The friction of moving long boom assemblages through the water can impose high tensile stresses on boom segments near the tow vessel.5.2 Tensile forces are also set up in a boom when it is being towed in a sweeping mode. The magnitude of this tensile force can be related to the immersed depth of the boom, the length of boom involved, the width of the bight formed by the two towing vessels, and the speed of movement.NOTE 1: When the towing speed exceeds about 1 knot (0.5 m/s), substantial oil will be lost under the boom.5.3 Knowledge of maximum and allowable working tensile stresses will help in the selection of boom for a given application and will permit specification of safe towing and anchoring conditions for any given boom.1.1 These test methods cover static laboratory tests of the strength of oil spill response boom under tensile loading.1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.1.3 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. For a specific hazard statement, see Section 7.1.4 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.

This guide covers design criteria, requirements, material characteristics, and essential features for oil spill dispersant application systems, it covers spray systems employing booms and nozzles for use on boats or ships and helicopters or airplane. The equipment description, equipment minimum performance specification, and equipment design are presented in details. Materials on ship or boat systems should be corrosion-resistant to salt water. All materials that come into contact with dispersants should be compatible with that dispersant.1.1 This guide covers design criteria, requirements, material characteristics, and essential features for oil spill dispersant application systems. This guide is not intended to be restrictive to a specific configuration.1.2 This guide covers 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 guide covers systems for use on ships, boats, helicopters, or airplanes.1.4 This guide is one of several related to dispersant application systems using booms and nozzles. One is on design, one on calibration, one on deposition measurements, and one on the use of the systems. Familiarity with all four guides is recommended.1.5 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.1.6 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.

4.1 This guide describes a methodology for estimating the effectiveness of an in-situ burn. It is intended to aid decision-makers and spill-responders in contingency planning, spill response, and training.4.2 This guide is not intended as a detailed operational manual for the ignition and burning of oil slicks. The guide does not cover the feasibility of an in-situ burn, or the evaluation of airborne emissions from a burn.4.3 It is generally accepted that a precise determination of the burn effectiveness will not be possible. However, the methodology presented in this guide can be used to provide a consistent and reasonable estimate.4.4 Burn effectiveness can be reported as total volume burned or burn efficiency (that is, volume burned of that available), or both.1.1 This guide relates to the use of in-situ burning of oil spills. The focus of the guide is in-situ burning of spills on water, but the techniques described in the guide are generally applicable to in-situ burning of land spills as well.1.2 The purpose of this guide is to provide information that will enable spill responders to estimate the volume of oil consumed in an in-situ burn.1.3 This guide is one of several related to in-situ burning. Other standards cover specifications for fire-containment booms and the environmental and operational considerations for burning.1.4 Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.4.1 Exception—Table 1, Table 2 and Fig. 2 provide inch-pound units for information only.1.5 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.1.6 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.
