API MPMS 8.1
Manual of Petroleum Measurement Standards Chapter 8 - Sampling Section 1 - Standard Practice for Manual Sampling of Petroleum and Petroleum Products
|Publication Date:||1 October 1995|
This standard presents procedures for manually obtaining samples of petroleum and petroleum products of a liquid, semi-liquid, or solid state whose vapor pressure at ambient conditions is below 101.32 kilopascals (14.7 pounds per square inch absolute). Procedures are also included for the sampling of free water and other heavy components associated with petroleum and petroleum products. If sampling is for the precise determination of volatility, use API MPMS Chapter 8.4 in conjunction with this standard. For sample mixing and handling, refer to API MPMS Chapter 8.3. The standard does not cover sampling of electrical insulating oils and hydraulic fluids. See Notes 1, 2, 3.
A summary of the manual sampling procedures and their applications is presented in Table 1.
Note 1: The procedures described in this standard may also be applicable in sampling most noncorrosive liquid industrial chemicals, provided that all safety precautions specific to these chemicals are followed.
Note 2: The procedure for sampling liquified petroleum gases is described in ASTM D1265; the procedure for sampling power hydraulic fluids is covered in ANSI B93.19 and B93.44; the procedure for sampling insulating oils is described in ASTM D923; and the procedure for sampling natural gas is described in ASTM D1145.
Note 3: The procedure for special fuel samples for trace metal analysis is described in an appendix to ASTM D2880.
