Abstract Composite materials show an extraordinary change of properties depending on service life. This implies the necessity to find tailored methods determine strength and residual composite cylinders. determination can be done by load cycle tests [1] or, in some cases, primarily slow burst [2]. The results both test need statistical assessment for precise description strength. Especially related has a high uncertainty. Sample size [3] scatter distribution were identified as major...
Abstract Hydraulic pressure testing of composite gas cylinders damages the cylinders, but provides very limited information. For this reason, Federal Institute Materials Research and Testing (BAM) demands assessment safety design types for retest periods more than three years by employing destructive small samples. This gives insight in properties not quantified current standards. Depending on cycle fatigue behaviour individual type either tests or slow burst are employed. In paper methods...
Emergency response units increasingly use pressure cylinders made from fibre composites for breathing air as elements of personal protective equipment (PPE). Such applications expose the composite to harsh temperature and handling conditions. At least in Europe, standards have been used certifying PPE, which are designed mandatory approval receptacles transport dangerous goods. Therefore, service conditions specific PPEs not accounted these standards. In this paper, BAM (Federal Institute...
Abstract ISO standards for gas cylinders made from aluminum alloys generally require heat treatment after the forming process. Such is a costly part of manufacturing Particularly due to increasing international trade, market-surveillance authorities need simple and reliable methods field-test proper treating. By present contribution difference in strength heat-treated non-heat-treated exemplarily shown several material analysis are investigated their suitability as field tests.
