Standard Practice for Manual Sampling of Petroleum and Petroleum Products
1.1 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.
