1.1 This test method covers a four-stroke cycle diesel engine test procedure for evaluating engine oils for certain high-temperature performance characteristics, particularly ring sticking, ring and cylinder wear, and accumulation of piston deposits. Such oils include both single viscosity...
5.1 Background-Prior to this test method, the ability of an engine lubricant to resist aeration was measured by the engine oil aeration test (EOAT) described in Test Method D6894. The continued availability of engine parts coupled with field service aeration problems led to concerns about the...
1.1 This guide focuses on obtaining the comparative moisture condition within the upper 1.0 in. (25.4 mm) stratum in concrete, gypsum, anhydrite floor slabs and screeds for field tests. Due to the wide variation of material mixtures and additives used in floor slabs and screeds, this methodology...
5.1 The complex shear modulus of asphalt mixtures is a fundamental property of the material. Test results at critical temperatures (Tcritical) are used for specifications for some mixes. Mixtures with stiffer binders, aged mixes, mixtures with higher amounts of fines (material finer than...
3.1 This test method is used for determining the amount of a temperature-specific volatile distillate fraction in cold mix asphalt mixtures. Note 1: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the...
This test method covers the determination of the resistance of porcelain-enameled utensils to thermal shock. A hot plate, timing device, container, and sponge shall be used. The surface temperature of the hot plate, determined by any suitable surface temperature measuring device, may...
