Standard Practice for
Manual Sampling of Petroleum and Petroleum Products1

This standard is issued under the fixed designation D 4057; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.

This test method has been approved by the sponsoring committees and accepted by the Cooperating Societies in accordance with
established procedures. This method was issued as a joint ASTM-API standard in 1981.

This standard has been approved for use by agencies of the Department of Defense.

1. Scope

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 psi). If sampling is for the
precise determination of volatility, use Practice D 5842 in
conjunction with this practice. For sample mixing and handling
of samples, refer to Practice D 5854. 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 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 3—The procedure for special fuel samples for trace metal
analysis is described in an appendix to Specification D 2880.
