16、raph with the following: “For cylinders manufactured from heat-treated alloys with ageing, the following applies. a) Below 150 C: No further precautions are required. b) From 150 C to 175 C: 1) If a manufacturers recommendations (supported by time and temperature data) have been followed, and a cont
17、rolled application of heat is used, e.g. in the curing of coatings, the cylinder need not be tested. 2) If a manufacturers recommendations have not been followed for a controlled application of heat, the cylinder requires mandatory testing. The cylinder shall pass the hydraulic pressure test after t
18、he application of heat. A sort test, e.g. hardness test, may be used before proceeding to a hydraulic test. The hydraulic test need not be performed if the sort test results in a failure, but in this case the cylinder shall be rendered unserviceable. c) Above 175 C: In no case shall the cylinder be
19、subjected to temperatures above 175 C. If the cylinder is inadvertently subjected to a temperature in excess of 175 C, the cylinder shall be rendered unserviceable unless it is requalified by passing the volumetric expansion test (see 11.3).” Copyright International Organization for Standardization

41、satisfied that at the completion of the inspection and test, the cylinders (single or those from bundles) can be reintroduced into service for a further period of time. The inspection and test are to be carried out only by persons who are authorized under the relevant regulations and competent in th
42、e subject to assure all concerned that the cylinders are fit for continued safe use. The results of inspection and testing for the cylinders that are specified in this International Standard determine whether a cylinder should be returned to service.

45、n and testing 1 Scope This International Standard deals with seamless aluminium-alloy transportable gas cylinders intended for compressed and liquefied gases under pressure, of water capacity from 0,5 l to 150 l; it also applies, as far as practical, to cylinders of less than 0,5 l water capacity. T
46、his International Standard specifies the requirements for periodic inspection and testing to verify the integrity of such gas cylinders for further service. This International Standard does not apply to periodic inspection and testing of acetylene cylinders or composite cylinders with aluminium-allo
47、y liners. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.
