5.1 The quality and effectiveness of TSA coatings is dependent on a variety of factors including surface preparation, coating materials, environmental conditions and control of the applications process. This practice addresses the fundamental variables and concerns relative to proper TSA application.5.2 TSA has been proven to offer resistance to the atmospheric corrosion of carbon steel pipe and to corrosion under insulation (CUI). The publication NACE No. 12/AWS C2.23M/SSPC-CS 23.00, AWS C2.18 and NACE SP0198 provide additional information regarding the performance of TSA coatings.1.1 This practice defines the minimum requirements for the application of Thermal Spray Aluminum (TSA) coatings to carbon steel pipe for the purpose of preventing atmospheric corrosion or corrosion under insulation. This practice is intended to be effective for TSA coatings applied at pipe manufacturing facilities or at on-site assembly locations.1.2 This practice is for the application of TSA to the external surfaces of piping to prevent atmospheric corrosion of insulated and non-insulated surfaces.NOTE 1: TSA has been found useful for temperatures up to 1000°F (540°C) for uninsulated surfaces and for preventing corrosion under insulation for pipes operating in the range of 25°F to 300°F (–4°C to 150°C) surface temperature.1.3 This practice includes requirements for surface preparation, materials, application and quality control of TSA applied to carbon steel piping at the pipe manufacturing facility or at an on-site-assembly location.1.4 This practice is expressed in both inch-pound and SI units. However, unless the order specifies the use of metric values, inch-pound units shall be used.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.

5.1 Pesticide regulations for the minimization of drift during pesticide application often require active ingredient (a.i.) product use under defined droplet size conditions. Spray performance with respect to transport and deposition of droplets and particles at target surfaces and product efficacy for desired applications are also affected by droplet size spectra. The effect of drift reduction adjuvants on droplet size spectra should be understood in this context. The present test method describes standard tests that can be conducted to investigate the performance of pesticide spray drift reduction adjuvants under simulated field use conditions for drift management decisions in the context of the entire spraying process. The measured reduction in driftable fines and shift in spray droplet size distribution can be used to reduce the buffer zones mandated by regulatory agencies.1.1 This test method is used to characterize the performance of pesticide spray drift reduction adjuvants with respect to spray droplet size spectra, volume of fines, and other use parameters under simulated field ground application conditions. This test method does not include any procedures to evaluate if pump shear degrades the performance of the spray drift reduction adjuvant.1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.NOTE 1: This method uses industry-standard units. The following conversions to SI units are provided for convenience: 1 mph = 1.61 kph; 1 in = 2.54 cm; 1 gal/acre = 9.36 L/hectare.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 This test method determines hiding power of a test paint by visual evaluation of a spray applied coating.NOTE 1: Test Method D2805 describes an instrumental method for determining hiding power. The paint film is applied at a uniform thickness (for example with a doctor blade), the film thickness is measured rigorously, and the opacity is determined photometrically. Hiding power is thereby determined with a high degree of precision.5.2 Test Method D6762 is less precise than Test Method D2805, but is commonly used since it is more closely related to the application characteristics of the paint and is simpler in concept and evaluation.1.1 This test method provides for the quantitative visual determination of the film thickness required to achieve full hiding. This film thickness is considered to be the hiding power of a test paint.1.2 This method applies only to spray applied coatings but its concepts are valid for other methods of application as well.1.3 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.1.4 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.1.5 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.
