Saklaw ng 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...
Kahulugan at Layunin 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...
Kahulugan at Layunin 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...
Kahulugan at Layunin 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...
Kahulugan at Layunin 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...
Kahulugan at Layunin 5.1 Ang pamamaraan ng pagsubok na ito ay nagbibigay ng isang standard na pamamaraan para sa pagpapasiya ng kulay ng mga materyales sa pagmamarka ng semento ng thermoplastic. Ang pamamaraan ng pagsubok ay maaaring gamitin kasabay ng iba't ibang mga pagtutukoy ng pagmamarka ng pavement ng thermoplastic upang matukoy kung ang materyal ay sumusunod sa mga inilarawan na pagtutukoy. Manufacturers of these materials can also use this...
Kahulugan at Layunin 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. Tala 1: This method has been used in other...
1 Saklaw 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 mga buwan. 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...
