Standard Test Method for Evaluating and Comparing Transfer Efficiency of Spray Applied Coatings Under Laboratory Conditions

SIGNIFICANCE AND USE
5.1 Subject to the limitations listed above, the procedure can be used as a research tool to optimize spray equipment and paint formulations as well as to study the relative effect on transfer efficiency of changing operating variables, spray application equipment, and types of coatings.
SCOPE
1.1 This test method covers the evaluation and comparison of the transfer efficiency of spray-applied coatings under controlled laboratory conditions.  
1.2 This test method has been shown to yield excellent intralaboratory reproducibility. Interlaboratory precision is poorer and is highly dependent on closely controlled air flow in the spray booth, the rate at which the paint is delivered to the part, and other variables suggested in the test method.  
1.3 Limitations:  
1.3.1 This laboratory procedure only indicates the direction of the effect of spray variables on transfer efficiency. The magnitude of the effect is determined only by specific plant experience.  
Note 1: This laboratory procedure requires specific equipment and procedures. For those laboratories that do not have access to the type of equipment required a more general laboratory procedure is being prepared as Procedure B.  
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are 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. For specific hazard statements, see Section 7 and 8.11.9 and 8.13.2.  
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.

ASTM D5162-21(Practice)
Standard Practice for Discontinuity (Holiday) Testing of Nonconductive Protective Coating on Metallic Substrates

SIGNIFICANCE AND USE
4.1 A coating/lining is applied to a metallic substrate to prevent corrosion or reduce product contamination, or both. The degree of coating continuity required is dictated by service conditions. Discontinuities in a coating/lining are frequently very minute and may not be readily visible. This practice provides a procedure for electrical detection of discontinuities in nonconductive coating systems.  
4.2 Electrical testing to determine the presence and number of discontinuities in a coating/lining is performed on a nonconductive coating/lining applied to an electrically conductive surface. The allowable number of discontinuities should be determined prior to conducting this test since the acceptable quantity of discontinuities will vary depending on film thickness, design, and service conditions.  
4.3 The low voltage wet sponge test equipment is generally used for detecting discontinuities in coatings/linings having a total thickness of 0.5 mm (20 mil) or less. High voltage spark test equipment is generally used for detecting discontinuities in coatings/linings having a total thickness of greater than 0.5 mm (20 mil).  
4.3.1 Coatings/linings less than 0.5 mm (20 mil) in thickness may be susceptible to damage if tested with high voltage spark testing equipment. However, coatings/linings greater than 0.25 mm (10 mil) and less than 0.5 mm (20 mil) may be tested with high voltage spark test equipment provided the voltage is calculated and set correctly, and the coating manufacturer approves its use.  
4.4 To prevent damage to a coating film when using high voltage test instrumentation, total film thickness and dielectric strength in a coating system shall be considered in determining the appropriate voltage for detection of discontinuities. Atmospheric conditions shall also be considered since the voltage required for the spark to gap a given distance in air varies with the conductivity of the air at the time the test is conducted. Table X1.1 in Appendix X1 cont...
SCOPE
1.1 This practice covers procedures for determining discontinuities using two types of test equipment:  
1.1.1 Test Method A—Low Voltage Wet Sponge, and  
1.1.2 Test Method B—High Voltage Spark Testers.  
1.2 This practice addresses metallic substrates. For concrete surfaces, refer to Practice D4787.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
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.

ASTM D1735-21(Practice)
Standard Practice for Testing Water Resistance of Coatings Using Water Fog Apparatus

SIGNIFICANCE AND USE
4.1 Water can cause the degradation of coatings, so knowledge of how a coating resists water is helpful in predicting its service life. Failure in water fog tests may be caused by a number of factors, including a deficiency in the coating itself, contamination of the substrate, or inadequate surface preparation. The test is therefore useful for evaluating coatings alone or complete coating systems.  
4.2 Water fog tests are used for research and development of coatings and substrate treatments, specification acceptance, and quality control in manufacturing. These tests usually result in a pass or fail determination, but the degree of failure may also be measured. A coating system is considered to pass if there is no evidence of water-related failure after a specified period of time.  
4.3 Results obtained from the use of water fog tests in accordance with this practice should not be represented as being equivalent to a period of exposure to water in the natural environment, until the degree of quantitative correlation has been established for the coating or coating system.  
4.4 The test apparatus is similar to that used in Practice B117, and the conversion of the apparatus from salt spray to water fog testing is feasible. Care should be taken to remove all traces of the salt from the cabinet and reservoir when converting from salt spray to water fog testing.
SCOPE
1.1 This practice covers the basic principles and operating procedures for testing water resistance of coatings in an apparatus similar to that used for salt spray testing.  
1.2 This practice is limited to the methods of obtaining, measuring, and controlling the conditions and procedures of water fog tests. It does not specify specimen preparation, specific test conditions, or evaluation of results.  
Note 1: Alternative practices for testing the water resistance of coatings include Practices D870, D2247, and D4585.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
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.

Standard Practice for Testing Water Resistance of Coatings Using Water Immersion

SIGNIFICANCE AND USE
4.1 Immersion in water can cause the degradation of coatings. Knowledge on how a coating resists water immersion is helpful in predicting its service life. Failure in a water immersion test may be caused by a number of factors including a deficiency in the coating itself, contamination of the substrate, or inadequate surface preparation. The test is therefore useful for evaluating coatings alone or complete coating systems.  
4.2 Water immersion tests are used for research and development of coatings and substrate treatments, specification acceptance, and quality control in manufacturing. These tests typically result in a pass or fail determination, but the degree of failure may also be measured. A coating system is considered to pass if there is no evidence of water-related failure after a specified period of time.  
4.3 Results obtained from water immersion tests in accordance with this practice should not be represented as being equivalent to a period of exposure to water in the natural environment, until the degree of quantitative correlation has been established for the coating or coating system.  
4.4 Corrosion tests of a scribed coating on a ferrous substrate are impractical in water immersion tests as the corrosion products tend to contaminate the water bath. Continuous overflow of the test tank is sometimes required to maintain consistent water quality.  
4.5 The apparatus for the test is relatively inexpensive and can be as simple as a glass beaker with a stirrer. It is also possible to use very large tanks for testing coated pipe or other large coated products.
SCOPE
1.1 This practice covers the basic principles and operating procedures for testing water resistance of coatings by the partial or complete immersion of coated specimens in distilled or de-mineralized water at ambient or elevated temperatures. Although the apparatus and procedure could be employed in immersion tests using solutions of various materials in water, this practice is limited to tests in water alone.  
1.2 This practice is limited to the methods of obtaining, measuring, and controlling the conditions and procedures of water immersion tests. It does not specify specimen preparation, specific test conditions, or evaluation of results.  
Note 1: Alternative practices for testing the water resistance of coatings include Practices D1735, D2247, and D4585.  
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use.

Standard Test Method for Measurement of Stain Resistance of Anodic Coatings on Aluminum

ABSTRACT
This specification covers measurement of strain resistance of anodic coatings on aluminium and its alloys, that have undergone a sealing treatment and contact with an acidic solution, are stainproof or nonadsorptive with respect to dyes. The method comprises contacting the test area of the anodized specimen with nitric acid solution and, after rinsing and drying, applying a special dye solution followed by rinsing and rubbing the test area with pumice powder, drying, and visual examination of the test area for retention of dye stain. Coatings that exhibit no dye stain or change in color are considered to have passed the test. Reagent grade chemicals shall be used in all tests. A specified solution of nitric acid shall be prepared in distilled or deionized water. A specified volume of aluminium blue 2WL dye shall be dissolved in distilled or deionized water.
SIGNIFICANCE AND USE
3.1 This test method is intended to determine whether anodic oxide coatings on aluminum and its alloys have been properly sealed and as a result are resistant to absorbing dyes.
SCOPE
1.1 This test method is intended to determine whether anodic oxide coatings on aluminum and its alloys, that have undergone a sealing treatment and contact with an acid solution, are stainproof or nonadsorptive with respect to dyes.  
1.2 Coatings that have been properly sealed should be proof against adsorption of coloring materials and, hence, “nonstaining” in many types of service.  
1.3 This test method is applicable to anodic coatings intended for applications where they are exposed to the weather, or for protective purposes in corrosive media, and where resistance to staining is important.
Note 1: Performance in this test is predictive only of susceptibility to stain by dyes. It is not intended to be predictive of other factors in service performance such as pitting or general corrosion.
Note 2: For Aluminum Association Class I and II architectural anodic coatings that are sealed in solutions containing less than 15 ppm silicates or 3 ppm phosphates, the acid pretreatment may be omitted.  
1.4 In the case of coatings colored in deep shades, where estimation of the intensity of any residual dye stain is difficult, interpretation of the test is based on whether or not the original color has been affected by the action of the test.  
1.5 This test method is not applicable to:  
1.5.1 Chromic acid type anodic coatings.  
1.5.2 Anodic coatings on aluminum alloys containing more than 2 mass % Cu or 4.5 mass % Si.  
1.5.3 Anodic coatings that have been sealed only in dichromate solutions.  
1.5.4 Anodic coatings that have undergone a treatment to render them hydrophobic.  
1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.7 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.  
1.8 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.

Standard Test Method for Operating Performance of Continuous Electrodeionization Systems on Feeds from 50 μS/cm to 1000 μS/cm

SIGNIFICANCE AND USE
5.1 The CEDI devices can be used to produce deionized water from feeds of pretreated water. This test method permits the relatively rapid measurement of key performance capabilities of CEDI devices using standard sets of conditions. The data obtained can be analyzed to provide information on whether changes may have occurred in operating characteristics of the device independently of any variability in feed water characteristics or operating conditions. Under specific circumstances, this test method may also provide sufficient information for plant design.
SCOPE
1.1 This test method covers the determination of the operating characteristics of continuous electrodeionization (CEDI) devices using synthetic feed solutions and is not necessarily applicable to natural waters. This test method is a procedure applicable to solutions with a conductivity range from approximately 50 μS/cm to 1000 μS/cm.  
1.2 This test method covers the determination of operating characteristics under standard test conditions of CEDI devices where the electrically active transfer media therein is predominantly unregenerated. This results in more rapid achievement of steady state and shorter test time than when performing a test which requires the active media be predominantly regenerated.  
1.3 This test method is not necessarily indicative of the following:  
1.3.1 Long-term performance on feed waters containing foulants or sparingly soluble solutes, or both,  
1.3.2 Performance on feeds of brackish water, sea water, or other high-salinity feeds,  
1.3.3 Performance on synthetic industrial feed solutions, pharmaceuticals, or process solutions of foods and beverages, or,  
1.3.4 Performance on feed waters less than 50 μS/cm, particularly performance relating to organic solutes, colloidal or particulate matter, or biological or microbial matter.  
1.4 This test method, subject to the limitations previously described, can be applied as either an aid to predict expected deionization performance for a given feed water quality, or as a test method to determine whether performance of a given device has changed over some period of time. It is ultimately, however, the user's responsibility to ensure the validity of this test method for their specific applications.  
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.6 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.  
1.7 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.

1.1 This specification covers zinc and tin alloy wire, including zinc-aluminum, zinc-aluminum-copper, zinc-tin, zinc-tin-copper and tin-zinc, used as thermal spray wire in the electronics industry.  
1.1.1 Certain alloys specified in this standard are also used as solders for the purpose of joining together two or more metals at temperatures below their melting points, and for other purposes (as noted in Annex A1). Specification B907 covers Zinc, Tin and Cadmium Base Alloys Used as Solders which are used primarily for the purpose of joining together two or more metals at temperatures below their melting points and for other purposes (as noted in the Annex part of Specification B907). Specification B833 covers Zinc and Zinc Alloy Wire for Thermal Spraying (Metallizing) used primarily for the corrosion protection of steel (as noted in the Annex part of Specification B833).  
1.1.2 Tin base alloys are included in this specification because their use in the electronics industry is similar to the use of certain zinc alloys but different than the major use of the tin and lead solder compositions specified in Specification B32.  
1.1.3 These wire alloys have a nominal liquidus temperature not exceeding 850 °F (455 °C).  
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 become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, 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.
