Gas cylinders. Refillable seamless steel. Performance tests - Philosophy, background and conclusions subscription-only A reciprocity calibration of microphones1 Scope This part of ISO TR 12931 applies to seamless steel refillable cylinders of all sizes from 0,5 l up to and including 150 l water capacity produced of steel with tensile strength (Rm) greater than 1 100 MPa. It can also be applied to cylinders produced of steels used at lower tensile strengths. In particular, it provides the technical rationale and background to guide future alterations of existing ISO standards or for developing advanced
