翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Small arms ammunition pressure testing ： ウィキペディア英語版 Small arms ammunition pressure testing Small arms ammunition pressure testing is used to establish standards for maximum average peak pressures of chamberings, as well as determining the safety of particular loads for the purposes of new load development. In metallic cartridges, peak pressure can vary based on propellant used, primers used, charge weight, projectile type, projectile seating depth, neck tension, chamber throat/leade parameters. In shotshells, the primary factors are charge weight, projectile weight, wad type, hull construction, and crimp quality. ==Modern civilian test methodologies== The two modern standardized test methodologies in use are the Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives or C.I.P. methodology, and the Sporting Arms and Ammunition Manufacturers' Institute or SAAMI methodology. The SAAMI methodology is widely used in the US, while C.I.P. is widely used in the mainly European C.I.P. member states. While both modern methodologies use piezo pressure transducer sensors to generate pressure readings, differences in the test setup mean that the same pressures will often generate very different readings depending on the method used. Because C.I.P. and SAAMI maximum pressures are measured differently, it is important to know which methodology was used to measure peak pressures. While C.I.P. pressures are often quoted in megapascals in Wikipedia and bars by C.I.P., and SAAMI in psi, it is not unusual to see C.I.P. pressures converted to psi or vice versa. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Small arms ammunition pressure testing」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
