3、use by agencies of the Department of Defense.1. Scope1.1 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
4、determination of volatility, use Practice D5842 (API MPMS Chapter 8.4) in conjunction with this practice. For sample mixing andhandling of samples, refer to Practice D5854 (API MPMS Chapter 8.3). The practice does not cover sampling of electricalinsulating oils and hydraulic fluids. A summary of the
5、 manual sampling procedures and their applications is presented in Table 1.Chapter 8.3). The practice does not cover sampling of electrical insulating oils and hydraulic fluids.NOTE 1The procedures described in this practice may also be applicable in sampling most noncorrosive liquid industrial chem
