《GB/T 8928-2008固体和半固体石油沥青密度测定法》由TC280(全国石油产品和润滑剂标准化技术委员会)归口,TC280SC4(全国石油产品和润滑剂标准化技术委员会石油沥青分会)执行,主管部门为国家标准化管理委员会。
本标准规定了采用比重瓶法测定固体和半固体石油沥青密度的试验方法;本标准不适用于测定相对密度小于1.000的固体石油沥青。本标准未涉及有关使用的安全规定,标准使用者有责任在使用前制定合适的安全应用规程。 本标准与美国材料与试验协会标准ASTM D70-03《半固体沥青材料密度测定法(比重瓶法)》(英文
版)和ASTM D2320-98(2003)《固体煤焦油沥青密度(相对密度)测定法(比重瓶法)》(英文版)的一致性程度为非等效。 本标准代替GB/T8928―1988《石油沥青比重和密度测定法》。本标准与GB/T8928―1988相比主要变化如下:
―――将标准名称由《石油沥青比重和密度测定法》改为《固体和半固体石油沥青密度测定法》;
―――增加了第2章规范性引用文件、第5 章意义与用途、6.2 天平、6.6 真空泵或水流泵和第7章取样。
Scope
This standard specifies the test method for determining the density of solid and semi-solid petroleum asphalt by the pycnometer method. This standard is not applicable to the determination of solid petroleum asphalt with a relative density less than 1.000. This standard does not involve safety regulations related to use, and it is the responsibility of standard users to formulate appropriate safety application regulations before use.
