(Test Method)Standard Test Method for No-Pick-Up Time of Traffic Paint
Standard Test Method for No-Pick-Up Time of Traffic Paint
SIGNIFICANCE AND USE
3.1 This test method serves as a laboratory control test. Types of traffic paints that can be tested with this method are waterborne, solventborne, and some 100 % solids liquid traffic paints. If wet film thickness, temperature, and humidity are controlled within the tolerances specified herein, this method can be useful for relative testing of traffic paints and potentially for qualification of traffic paints for field application in approved specifications. For improved repeatability and meaningful comparison of paint samples being tested, consistent air flow over the paint films during testing is important. Although a no-air-flow (static) test environment is standard, 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 traffic paint (for example, 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.

FIG. 2 Picture of Apparatus and Traffic Paint Film Being Tested
Each pass of wheel over the paint film should be at least 2.5 mm (1 in.) from each end of the paint film.
SCOPE
1.1 This test method covers a laboratory procedure for determining the no-pick-up time of a traffic paint. 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 traffic paint film repeatedly until there is no transfer of paint to the rubber rings. The elapsed time from paint film application to point of no paint transfer is the no-pick-up time. Key variables to be controlled during testing are film thickness, temperature, humidity, and air flow.
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.

3. Significance and Use
3.1 This test method serves as a laboratory control test. Types of traffic paints that can be tested with this method are waterborne,
solventborne, and some 100 % solids liquid traffic paints. This test is most commonly used with fast-dry waterborne traffic paints.
If wet film thickness, temperature, and humidity are controlled within the tolerances specified herein, this method can be useful
for relative testing of traffic paints and potentially for qualification of traffic paints for field application in approved specifications.
For improved repeatability and meaningful comparison of paint samples being tested, consistent air flow over the paint films during
testing is important. Although a no-air-flow (static) test environment is standard, 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). No-pick-up times for fast-dry waterborne traffic
paints are typically less than 10 min in a static air flow condition. Because of the many variables operative in the field application
of traffic paint (for example, 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.
