Abstract
Applicable for sampling from containers (cylinders, drums, tanks, etc.). Sampling of the product in a steel cylinder, previously cleaned, dried and evacuated. The stainless steel cylinder shall be capable of withstanding an internal pressure of at least 3 MPa (30 bar). The cylinder is filled to the filling ratio allowed by the safety considerations. Details are given in the relevant international standards for the products considered. The samples shall be taken only from the liquefied phase. A diagram of the sampling assembly is shown in a figure.
