Asphaltene content is defined as those components not soluble in n-heptane.1.1 This test method covers determination of the mass percent of asphaltenes as defined by insolubility in normal-heptane solvent. It is applicable to all solid and semi-solid petroleum asphalts containing little or no mineral matter, to gas oils, to heavy fuel oils, and to crude petroleum that has been topped to a cut-point of 343176;C or higher.1.2 The values stated in SI units are to be regarded as the standard.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. See Section 7 for a specific hazard statement.【中国标准分类号】: E30;Q20【国际标准分类号】: 91_100_50 ; 93_080_20【页数】: 4P.;A4【正文语种】: 作者: 血色残阳 时间: 2016-5-4 16:35:22
