35、The use of amanual piston cylinder in place of open containers is intendedto prevent the loss of volatile (light end) components, whichcan impact subsequent test results.1.3 This practice is suitable for sampling crude oils,condensates, and/or liquid petroleum products having truevapor pressures les

Thispractice shall not be used for materials classified as UN Class2 Gases2(“having a vapor pressure greater than 300 kPa at50 C or is completel
