Right now they are trying to double charge us which is horrible business practice, and trying to handle this with customer service has been an absolute nightmare. Reported are the changes in tensile strength, hardness, and volume of the elastomer. The sample is oscillated and measured until a constant value is obtained. This test determines the amount of MoS2 in grease. Viscosity is defined as the resistance to flow of a substance. This test determines base number. Polymers are added to improve the viscosity index of these fluids. This method determines flash points from 40°C to 370°C for petroleum products or 60°C to 190°C for biodiesel fuels. This test determines the penetration values of thread compounds at both a room temperature and a below-freezing temperature to assure that the material will remain pliable when cold. On 9/1/2020 I thought I had reached a point where they potentially wouldn't go any lower and requested a call to renew the contract. Evaporative losses may also increase emissions and are therefore regulated in some localities. The sample is placed in a DSC, and the temperature is slowly increased until the range of interest is covered. BPRR 29 Petro Lube Oil, Petro Res Oils, Min Oil, Petro Wax, Petrolatum and Elev Temp Liquid (Effective February 1, 2020) BPRR 4060.21 Scrap Iron or Steel (Effective January 1, 2021) BPRR 4619.21 Railway Freight Cars or Locomotives (Effective January 1, 2021) The prepared metals and prepared sample are placed in a beaker fitted with a rubber stopper, condenser and aerator tube. The mixture is titrated with potassium hydroxide to a color-changing endpoint. Steam turbines typically operate continuously, with long periods between servicing. ASTM D6482 Determination of Cooling Characteristics of Aqueous Polymer Quenchants by Cooling Curve Analysis with Agitation (Tensi Method) When metals are heated to high temperatures and formed into desired products, they must then be cooled to room temperature. For the flammability of aerosols consider ASTM D3065. Using a computer-enhanced data collection system, the progression of the test is followed and a time versus coefficient of friction graph is generated. Reported is the grams of oil separated from the grease and the percent change in penetration value. The water bath is slowly heated until a drop of sample falls from the thermometer. Test Method A reports weight percent or ppm by weight. The viscosity of grease observed when the grease is flowing, the apparent viscosity is determined in this method. Static bleed refers to the separation of oil from grease during storage. The value is useful for fluid specifications in hydraulic systems. The sample is placed in the test cup, slowly heated and periodically exposed to a flame. The endpoint is determined by either colorimetrically (method A) or potentiometrically (method B). Refractive indexes of lubricants and hydrocarbons tend to increase with average molecular weight, density, purity and degree of saturation. The most typical test run is for 24 hours @ 100°C. I'll save at least one thousand dollars this year. After surface preparation and cleaning the panels are dipped in the oil sample, then drained for 2 hours before placing them in the test chamber maintained at 120°F for the specified exposure time. It is heated to the test temperature for the test time (Procedure A) or until a predetermined mass loss is observed (procedure B). For non-soap thickened greases see FTM 3722. The fluid is placed in a laser particle counter and the quantity and size of particles in the fluid are determined and reported. Appropriate additive levels are essential for proper functioning of the lubricant. All three methods can be used to determine the kinematic viscosity. The relative resistance to shearing can be determined with this test method. This test determines the percent of active sulfur in lubricating oils. Abrasive particles may damage system components and cause premature bearing failure. The torque resulting from grease lubricated ball bearings rotated at one rpm is measured. At the conclusion of the test, the metals are removed, cleaned, dried and weighed. The Dielectric Constant is a measure of the insulator's ability to resist electrical flow under increasing frequency. The titer point is observed and reported in °C at the solidification point of the sample. A quick google search shows that the rate for most oil companies today is about $1.44 a gallon. "Not to my knowledge." Consider a pycnometer test (see ASTM D1481) for solids, greases and highly viscous oils. When a substance melts, freezes or undergoes a glass transition, thermal properties such as heat of expansion, specific heat and thermal conductivity change. Elastomers, plastics and rubber compounds in the electrical systems may be exposed to silicone lubricants. The mass percentage lost is reported. When light passes from air into a transparent liquid, the light bends, often giving the liquid a characteristic appearance. This test determines aerosol flammability using two methods: Flame Projection Test and Closed Drum Test. These are the I-80 truck stops in the TruckMaster® Fuel Finder™ database. Mineral oils normally have very low saponification numbers, animal or plant based oils normally have very high saponification numbers. Oil prices have dropped dramatically since the Covid pandemic. Water-soluble contaminants may change the properties and stability of lubricants formulated with MoS2. A “pass” is reported if the film remains oily to the touch. In a standard grease worker, the grease is pushed back and forth through a metal plate with holes. To control the cooling rate, the hot fabricated metal is placed in a quenching fluid and allowed to cool. Colored standard solutions are prepared. A sample of grease is heated in the drop point cup until the sample melts or separates and runs out a small hole in the bottom of the cup. Halogenated organic solvents are used in metal cleaning products, automotive aerosols and lubricants. The sample is accurately weighed in the test pan and heated at a controlled rate using a differential scanning calorimeter (DSC). Please refer to ASTM D4950 for a full specification. Hence my summary ~ considering Petro - RUN, run away!! The sample is weighed, placed in a heated oven for the test time, cooled in a desiccator and reweighed. This method determines the viscosity index of lubricating oils. A standard ABEC 6204 test bearing is packed with 4 grams of the grease to be tested. The oil-free, moisture-free sample from PLTL-20 is put through a series of extractions and washings resulting in the insoluble residue on a filter paper. The report lists the number of rust spots less than 0.1 cm, 0.1cm to 0.2cm and greater than 0.2cm. This test determines vapor pressures of liquids. Proper usage often necessitates knowing the level of formaldehyde in starting materials. The separated oil is drained, measured and the percent separation is reported. (2) 60 stroke worked penetration – the standard usually used to compare various greases and to assign NLGI numbers. If the base number is to be determined, the mixture is titrated with hydrochloric acid. The sample is placed in a cooling tube fitted with a temperature measuring device and a spiral stirring rod. On the 8/26/2020 call the representative was getting frustrated with me continuing to state that they can bring the price lower. Compounds such as oils and polymeric materials can change from this brittle, glass-like state to a more flexible, rubber-like state as they are allowed to warm and pass through their glass transition temperature. Reported is the number of particles in 100 ml sample >5µm and >15µm, and the two digit ISO Solid Contaminant Code. Stroking usually changes the consistency of grease, and grease stroked for prolonged periods of time may show further consistency changes. To safely slow down or stop a moving vehicle, brake cylinder components should move freely, rapidly and smoothly, regardless of the ambient temperature. Solid film lubricants are attractive for use on difficult- to-access gears, fasteners, bearings and CV joints because they do not require frequent re-lubrication,. Please specify the temperature. I will be shopping elsewhere for my oil and I hope you do too. Vapor pressure gives an indication of the evaporation rate of a substance. I gave them the benefit of the doubt and followed through with the second safety check. A fail is reported if the test surface contains one or more dots of rust larger tahn 1mm in diameter or if it contains four or more dots of any size. Sequence I, II and III are performed at 24°C (75°F), 93.5°C (200°F) and 24°C (75°F) respectively. Torques greater than 35,000 g-cm (3.5 N-m) are considered to be technically frozen. Most fluids exhibit a load at which metal to metal contact is minimal and the amount of wear produced on the basis of scar diameter is no more than 5% greater than the impression diameter (the plastic deformation of the balls under point contact load without turning the machine on). Reported are changes in the metal (weight loss and residue deposited on each metal), fluid characteristics: (change in precipitation number (ASTM D91) and change in viscosity (ASTM D445)); and the appearance of the oxidation tube. This test determines the titer point (solidification temperature) of fatty acids and fatty acid mixtures. The torque resulting from grease lubricated tapered roller bearings rotating at one rpm is measured.
