1 新材料及其“规范案例”的应用说明新材料的开发和应用是锅炉及压力容器制造取得技术进步的基础。当ASME收到并受理使用新材料的申请后,规范委员会考虑制定并发布有效期为3年的“规范案例”以“提供现行规范未覆盖的材料或制造的规则”。虽然规范案例不只限于对于材料及其使用的规定,但多数是材料方面的案例。 “规范案例”与规范的卷册同步出版。它是在每一次总委员会会议后、经过与其他修改和补充的批准程序产生。规范案例允许使用在目前版本锅炉
A new material and its “Code Case ” application description The development and application of new materials for boiler and pressure vessel manufacturing made the basis for technological progress. When ASME receives and accepts applications for the use of new materials, the Codex Committee will consider developing and promulgating a “Code Case” valid for 3 years to provide “Rules for Materials or Manufacturing Not covered by Current Practices”. Although the normative case is not limited to the material and its use, most are material cases. “Canonical case ” and standard volume book published simultaneously. It is produced after every General Committee meeting, with the approval and other amendments and additions. The standard case allows the use of the boiler in the current version
