Pomen in namen 4.1 The deterioration of insulation coating is closely related to its moisture content. Water permeability testing provides a means of monitoring the passage of water through a coating material by its change in dielectric constant. When expressed in time, the test data will reflect the rate of deterioration...
Pomen in namen 4.1 Solvents in traffic paints may cause road surface components to penetrate into traffic markings, thus making traffic markings less effective as lane or direction indicators. This procedure describes how to prepare a panel for the coating under test and a reference panel coated with a specific solvent...
Pomen in namen 4.1 This practice aims to assess the wear resistance of road markings. It should be noted that the high wear resistance of road markings applied to exposed road surfaces may not guarantee similar results when the same road markings are applied to old road surfaces. ASTM D 913-2020 "Evaluating...
Pomen in namen 3.1 Paint may over-settle if improperly formulated or processed. Oversettled paint is difficult to reintegrate into the paint system, resulting in time delays or valuable pigment remaining in the drum. This test method attempts to assess the extent of settlement caused by the accelerated test method D1309. The...
Pomen in namen 5.1 This test method provides a standard procedure for color determination of thermoplastic pavement marking materials. The test method can be used in conjunction with various thermoplastic pavement marking specifications to determine whether the material complies with the described specifications. Manufacturers of these materials can also use this...
Pomen in namen 4.1 The roundness of a glass sphere is a measurable aspect related to its performance as a retroreflective medium. The function of this test method is to measure the percentage of true spheres associated with compliance with the applicable specification. Opomba 1: This method has been used in other...
1 Obseg 1.1 This method involves laboratory test steps over a period of two weeks to simulate possible settlement of road sign paint in normal storage for approximately 12 mesecih. 1.2 This standard is expressed in IN-1B units and the values given in parentheses are for reference only. 1.3 This standard is not...
Pomen in namen 4.1 Traffic coatings need to have good resistance to oil and fuel dripping on highways. The test method describes the procedures required to evaluate the resistance of a traffic paint to a reference test fluid to simulate such actions. Področje uporabe 1.1 This specification describes a laboratory procedure for determining...
