ASTM D4057-95(2000)

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 D5842 in conjunction with this practice. For sample mixing and handling of samples, refer to Practice D5854. 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 method 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 liquified petroleum gases is described in Practice D1265; 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 Test Method D923; and the procedure for sampling natural gas is described in Test Method D1145. Note 3-The procedure for special fuel samples for trace metal analysis is described in an appendix to Specification D2880.
