Industrial valves — Measurement, test and qualification procedures for fugitive emissions — Part 1: Classification system and qualification procedures for type testing of valves 1 Scope This part of ISO 15848 specifies testing procedures, for evaluation of external leakage of valve stem seals (or shaft) and body joints of isolating valves and control valves intended for application in volatile air pollutants and hazardous fluids. End connection joints, vacuum application, effects of corrosion and radiation are excluded from this part of ISO 15848. This part of ISO 15848 concerns classification system and qualification procedures for type testing of valves. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 5208, Industrial valves — Pressure testing of valves 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 body seals any seal in pressure containing part except stem (or shaft) seals 3.2 Class a convenient round number used to designate pressure-temperature ratings NOTE It is designated by the word “Class” followed by the appropriate reference number from the following series: Class 125, Class 150, Class 250, Class 300, Class 600, Class 900, Class 1 500, Class 2 500. 3.3 concentration ratio of test fluid volume to the gas mixture volume measured at the leak source(s) of the test valve NOTE The concentration is expressed in ppmv (parts per million volume), which is a unit deprecated by ISO (1 ppmv = 1 ml/m3 = 1 cm3/m3).
