범위 1.1 This test method includes an accelerated procedure for simultaneously determining the comparative characteristics of the insulating coating system applied to the exterior of the steel pipe with the purpose of preventing or mitigating corrosion that may occur in underground service where the pipe will come into contact with...
의미와 목적 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...
의미와 목적 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...
의미와 목적 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...
의미와 목적 3.1 부적절하게 구성되거나 처리되면 페인트가 과도하게 침전될 수 있습니다.. 과도하게 침전된 페인트는 페인트 시스템에 다시 통합되기 어렵습니다., 시간이 지연되거나 드럼에 귀중한 색소가 남게 됩니다.. 이 시험 방법은 가속 시험 방법 D1309로 인한 침하 정도를 평가하려고 시도합니다.. 그만큼...
의미와 목적 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...
의미와 목적 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. 메모 1: This method has been used in other...
1 범위 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 months. 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...
