1.1 This International Standard recommends procedures to be used for obtaining, by automatic means, representative samples of crude oil and liquid Petroleum products being con- veyed by Pipeline. NOTE - Although throughout this International Standard the term crude oil is used, this should be taken to include other Petroleum liquids where the technique and equipment are also applicable. 1.2 This International Standard does not apply to the sampling of liquefied Petroleum gases and liquefied natura1 gases. 1.3 The principal purpose of this International Standard is to give guidelines for specifying, testing, operating, maintaining and monitoring crude oil Samplers. 1.4 The sampling procedures for crude oil are intended to provide representative samples for the determination of a) the oil composition and quality; b) the total water content; c) other contaminants that are not considered to be part of the crude oil transferred.
