本文件的目的是就如何证明压力设备的现场制造和组装在设备预期用户的直接控制下（在本文件中称为最终用户）符合法律规定提供实用建议。与压力设备相关的各种设计、施工和安装评估路线的摘要如以下流程图（图1）所示。最终用户应遵循此流程图，以确保他们正确遵循了适当的合规路线。

The purpose of this document is to provide practical advice on how legal compliance should be demonstrated where on-site manufacture and assembly of pressure equipment are undertaken under the direct control of the intended user of the equipment (and shall be subsequently referred to as the end user in this document).A summary of the various design, construction and installation assessment routes related to pressure equipment are illustrated in the flowchart (Figure 1) below. The end user should follow this flowchart, to ensure they have correctly followed the appropriate compliance route.
