(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. 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.
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 and health practices and determine the applicability of regulatory limitations prior to use.

Fig. 3) and is faster at higher flow rate. Even minor variations in air movement at different locations within the same laboratory
can affect no-pick-up time results. The conditions and associated apparatus for controlling air flow are described in the following
subsections.
4.6.1 To minimize the effects of air flow, a location for testing in the laboratory should be selected that is free of drafts with
no perceptible air movement. An air flow meter (anemometer) may be helpful in detecting drafts. The use of an anemometer is
detailed in Practice D5741. If drafts are detected, air flow can be minimized by using an enclosure (open front with solid top, back,
and sides) around the test apparatus with approximate dimensions 61 cm wide by 46 cm deep by 46 cm tall (24 by 18 by 18 in.).
The enclosure can be made of plastic or other suitable material. If an air conditioning system is used to control room temperature
and humidity, the system should be set to “On” rather than “Auto” to maintain constant air movement during testing. Note that
test chambers with high air turnover may give much faster no-pick-up times.
4.6.2 Upon mutual agreement by purchaser and seller, another option for regulating air flow during testing is to establish
controlled air flow over the applied paint film at some fixed wind speed. One possible apparatus to control wind speed is shown
in Fig. 4. This setup includes a 51 cm (20 in.) box fan, a variable transformer (voltage regulator) for fan speed control, and a
precision anemometer for measurement and adjustment of the air flow. In a standard format, the glass plate for paint film drawdown
is located 61 cm (24 in.) from the fan perpendicular to the air flow. A precision anemometer is located on the opposite side of the
glass plate. The variable transformer is adjusted to obtain the desired wind speed over the glass plate. Once the correct wind speed
is obtained, the paint film is drawn down on the glass plate and no-pick-up testing is conducted. If this approach is used, a wind
speed of 3.2 to 6.4 kph (2 to 4 mph) is recommended where the slope of dry time versus wind speed is lower and in the linear
region (see Fig. 3). For most consistent results, the air flow should be controlled to within 60.16 kph (60.1 mph).
5. Procedure
5.1 Prepare a test stripe at least 75 mm (3 in.) in width of the paint to be tested by a mechanical spreader, or other suitable means
on a clean plate glass panel at a wet film thickness of 0.38 6 0.01 mm (15 6 0.5 mils). Use a plate glass panel approximately
100 by 200 by 3 mm (4 by 8 by ⁄8 in.). Procedures for producing uniform paint films are found in Practices D823: Practice C,
Motor Driven Blade Film Applicators, and Practice E, Hand Held Blade Film Applicators. Be aware that the number (in mils,
microns, or mm) printed on many types of film applicator “draw-down” bars is the clearance (gap), and that the thickness of the
paint applied using those applicators is often significantly less than the gap (typically 50 to 70 % of the clearance for waterborne
traffic paints). Some “Bird” applicators have markings that indicate the approximate wet film thickness expected, while some “bird
type” applicators have markings indicating the gap. The applied paint films should be checked for wet film thickness to ensure that
