《分析用煅烧石油焦试样的制备规程》是石油,石油产品分类下的标准,This practice provides field personnel and laboratories with standard procedures for dividing, reducing, and mixing gross samples and intermediate samples, such that the resulting prepared analysis samples are more uniform from laboratory to laboratory. Adherence to these guidelines is expected to provide significant reduction in interlaboratory variability.1.1 This practice covers the preparation procedures necessary for the reduction and division of calcined petroleum coke samples in order to generate appropriate analytical samples upon which physical and chemical analytical tests will be performed. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.其主要内容是试样,规程,煅烧,石油焦。
《源自废轮胎的燃油的使用规程》是石油,石油产品分类下的标准,1.1 This practice covers and provides guidance for the material recovery of scrap tires for their fuel value. The conversion of a whole scrap tire into a chipped formed for use as a fuel produces a product called tire-derived fuel (TDF). This recovery practice has moved from a pioneering concept in the early 1980s to a proven and continuous use in the United States with industrial and utility applications.1.2 Combustion units engineered to use solid fuels, such as coal or wood or both, are fairly numerous throughout the U.S. Many of these units are now using TDF even though they were not specifically designed to burn TDF. It is clear that TDF has combustion characteristics similar to other carbon-based solid fuels. Similarities led to pragmatic testing in existing combustion units. Successful testing led to subsequent acceptance of TDF as a supplemental fuel when blended with conventional fuels in existing combustion devices. Changes required to modify appropriate existing combustion units to accommodate TDF range from none to relatively minor. The issues of proper applications and specifications are critical to successful utilization of this alternative energy resource.1.3 This practice explains TDF”s use when blended and combusted under normal operating conditions with originally specified fuels. Whole tire combustion for energy recovery is not discussed herein since whole tire usage does not require tire processing to a defined fuel specification.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.其主要内容是燃油,规程,源自,废轮胎。
《石蜡滴点的测试方法》是石油,石油产品分类下的标准,Waxes do not go through a sharp solid-liquid phase change when heated and therefore do not have a true melting point. As the temperature rises, waxes gradually soften or become less viscous. For this reason, the determination of the softening point must be made by an arbitrary but closely defined method if test values are to be reproducible. This test is useful in determining the consistency of waxes, and as one element in establishing the uniformity of shipments or source of supply. This test method has been found suitable for all types of waxes including paraffin, microcrystalline polyethylene, and natural waxes.1.1 This test method covers the determination of the ASTM dropping point for waxes. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.其主要内容是石蜡,滴点,测试方法。
