【英文标准名称】: Practice for Manual Sampling of Petroleum and Petroleum Products 【原文标准名称】: 石油及石油产品人工取样规程 【标准号】: ANSI/ASTM D4057-2006 【标准状态】: 作废 【国别】: 美国 【发布日期】: 2006 【实施或试行日期】: 2006-05-23【发布单位】: 美国国家标准学会(US-ANSI)【起草单位】: ANSI【标准类型】: ()【标准水平】: ()【中文主题词】: 石油产品;抽样方法【英文主题词】: Lubricants;Manual;Petroleum;Petroleum products;Processes;Sampling methods【摘要】: This practice covers procedures for manually obtaining representative samples of petroleum products of a liquid, semi-liquid, or solid state whose vapor pressure at ambient conditions is below 101 kPa (14.7 psia). If sampling is for the precise determination of volatility, use Practice D 5842 (API MPMS Chapter 8.4) in conjunction with this practice. For sample mixing and handling of samples, refer to Practice D 5854 (API MPMS Chapter 8.3). The practice does not cover sampling of electrical insulating oils and hydraulic fluids. A summary of the manual sampling procedures and their applications is presented in Table 1. Note 1 - The procedures described in this practice may also be applicable in sampling most noncorrosive liquid industrial chemicals, provided that all safety precautions specific to these chemicals are strictly followed. Note 2 - The procedure for sampling liquefied petroleum gases is described in Practice D 1265; the procedure for sampling fluid power hydraulic fluids is covered in ANSI B93.19 and B93.44; the procedure for sampling insulating oils is described in Practice D 923; and the procedure for sampling natural gas is described in Test Method D 1145. Note 3The procedure for special fuel samples for trace metal analysis is described in an appendix to Specification D 2880.【中国标准分类号】: E31;E21【国际标准分类号】: 75_080;75_100【页数】: 【正文语种】: 英语
