Standard Test Method for Chipping Resistance of Coatings

Standard Test Method for Chipping Resistance of Coatings

SIGNIFICANCE AND USE
4.1 Owners consider chipping of coatings, particularly on the leading faces and edges of automobile surfaces, unacceptable. In formulating a coating or coating system to meet service requirements, the resistance to chipping damage by flying objects such as gravel is one of the properties of importance since it can vary considerably as other properties are adjusted. Since resistance to chipping decreases at lower temperatures partly as the result of decreased flexibility, the test may be more directly related to service conditions by performing it at a low temperature. This test method is designed to produce a controlled amount of impact by the media on the coated panel in order to enhance reproducibility.
SCOPE
1.1 This test method covers the determination of the resistance of coatings to chipping damage by stones or other flying objects.  
Note 1: This test method is similar to SAE J-400.  
1.2 All dimensions are nominal unless otherwise specified.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
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 D2805-11(2023)(Test Method)
Standard Test Method for Hiding Power of Paints by Reflectometry

SIGNIFICANCE AND USE
5.1 This is a precise instrumental method giving results having an absolute physical significance without reference to a comparison paint. It should be used when maximum precision and minimum subjectivity are required, as in testing specification coatings or evaluating the hiding efficiency of pigments.  
5.2 Hiding power Test Method D344 is visual instead of instrumental, and gives results that are relative to a material standard instead of absolute. It is less precise than Test Method D2805 but more closely aligned with practical painting procedures.
SCOPE
1.1 This test method covers the determination, without reference to a material paint standard, of the hiding power of air dry coatings with Y tristimulus values greater than 15 %. With appropriate modification, it can also be used to test baking finishes.  
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 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.

ASTM D6762-18(2023)(Test Method)
Standard Test Method for Determining the Hiding Power of Paint by Visual Evaluation of Spray Applied Coatings

SIGNIFICANCE AND USE
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.
SCOPE
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.

ASTM D6486-23(Practice)
Standard Practice for Short Term Vehicle Service Exposure of Automotive Coatings

SIGNIFICANCE AND USE
4.1 Since the exposure of automotive coatings to the various mechanical and chemical stresses encountered in actual operations, is very opportunistic, obtaining statistically significant data from which valid conclusions can be drawn, requires rigorous attention to the experimental designs and conditions of exposure.
SCOPE
1.1 This practice covers the protocol for vehicle service exposure testing of automotive coatings. Such exposure testing is valuable for the verification of the performance of automotive coatings and correlation with laboratory test data. Vehicle service exposure is intended to provide short term (2 to 20 weeks) exposure to the stress factors associated with vehicle operation. Factors included are scratch, mar, impact, stone chipping, insect impact, bird dropping, tree sap and staining, environmental fallout, etc.
Note 1: Vehicle service exposure is not intended to provide the conditions that are needed for characterizing the long term effects of weathering or corrosion exposure.  
1.2 The exposure conditions are produced by the placement of multiple test panels of automotive finishes on automotive test fleets that traverse a defined road course. Exposure to the operating environment can be 20 h/day, 7 days/week allowing for accumulation of over 100 000 miles in 10 weeks of exposure.  
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 D711-23(Test Method)
Standard Test Method for No-Pick-Up Time of Pavement Markings

SIGNIFICANCE AND USE
3.1 This test method serves as a laboratory control test. Types of pavement markings that can be tested with this method are waterborne traffic paint, solvent borne traffic paint, and some two component 100 % solids liquid pavement markings, such as epoxy and modified epoxy pavement markings. If wet film thickness, temperature, and humidity are controlled within the tolerances specified herein, this method can be useful for relative testing of pavement markings and potentially for qualification of pavement markings for field application in approved specifications. For improved repeatability and meaningful comparison of pavement markings samples being tested, consistent air flow over the pavement marking films during testing is important. The buyer and seller should agree upon the air flow conditions, whether it be static or carefully regulated air flow (see 4.6.1 and 4.6.2). Because of the many variables operative in the field application of pavement markings (for example, wet film thickness, air temperature, humidity, wind speed, pavement type (asphalt or concrete), film profile over pavement, pavement temperature, pavement porosity, pavement moisture content, and the presence or absence of direct sunlight during striping), a direct correlation between the results of this test and field applications is difficult to obtain. However, relative field performance can be predicted using this method if the testing protocol is adhered to. For testing of two component 100 % solids liquid pavement markings an application of drop on retroreflective optics are typically applied at a specified rate to the markings prior to testing. For these types of pavement markings the regulation of air flow is not necessary due to the drying mechanics of the product.
SCOPE
1.1 This test method covers a laboratory procedure for determining the no-pick-up time of pavement markings. The method uses a wheel consisting of a metal cylinder with rubber O-rings. The wheel is rolled down a ramp over a freshly applied pavement marking film repeatedly until there is no transfer of the marking material to the rubber rings. The elapsed time from pavement marking film application to point of no marking material transfer is the no-pick-up time. Key variables to be controlled during testing are wet film thickness, temperature, humidity, air flow, and use of retroreflective optics. This standard provides three options for the testing of the no-pick-up time for pavement markings. The first option, Method A, specifies controls for temperature, humidity, and air flow during testing; a second option, Method B, specifies controls for temperature and humidity during testing, and a third option, Method C, provides guidance for performing this with a drop on application of retroreflective optics such as glass beads, Waterborne and Solvent Borne pavement markings are typically tested using Procedure A or Procedure B, without the application of drop on retroreflective optics. Pavement markings that are two component 100 % solids are typically tested using Method C.  
1.2 The values stated in SI units are to be regarded as the 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.

Standard Practice for Preparation of Zinc-Coated and Zinc-Alloy-Coated Steel Panels for Testing Paint and Related Coating Products

SIGNIFICANCE AND USE
3.1 The procedures described in this practice are designed to provide uniform zinc coated steel panels for testing of paint, varnish, lacquer, conversion coatings and related products.  
3.2 The proper description of the zinc coating on the substrate is an important part of this practice. Seemingly slight differences in zinc coating can produce substantial differences in coating performance.
SCOPE
1.1 This practice covers the preparation of zinc-coated and zinc-alloy-coated sheet steel panels to be used for testing paint, varnish, lacquer, conversion coatings, and related products. It covers sheet steel coated with hot dipped galvanized, one-side galvanized, electrogalvanized, zinc-iron alloy coatings (such as galvanneal), and zinc-5 % aluminum alloy coatings. It does not cover steel panels coated with 55 % aluminum-45 % zinc alloy, because these behave more like aluminum than zinc.  
1.2 The values stated in SI units are to be regarded as the 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.
