Significado y propósito 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...
Significado y propósito 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...
Significado y propósito 4.1 Esta práctica tiene como objetivo evaluar la resistencia al desgaste de las marcas viales.. Cabe señalar que la alta resistencia al desgaste de las marcas viales aplicadas a superficies de carreteras expuestas puede no garantizar resultados similares cuando las mismas marcas viales se aplican a superficies de carreteras antiguas.. ASTM D 913-2020 "Evaluating...
Significado y propósito 3.1 La pintura puede asentarse excesivamente si se formula o procesa incorrectamente.. La pintura demasiado sedimentada es difícil de reintegrar al sistema de pintura., lo que provoca retrasos en el tiempo o pigmentos valiosos que quedan en el tambor. Este método de prueba intenta evaluar el grado de asentamiento causado por el método de prueba acelerado D1309.. The...
Significado y propósito 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...
Significado y propósito 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. Nota 1: This method has been used in other...
1 Alcance 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 meses. 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...
Significado y propósito 4.1 Los recubrimientos de tráfico deben tener una buena resistencia al aceite y al combustible que gotea en las carreteras. El método de prueba describe los procedimientos requeridos para evaluar la resistencia de una pintura de tráfico a un fluido de prueba de referencia para simular tales acciones. Ámbito de aplicación de 1.1 This specification describes a laboratory procedure for determining...
