ISO 16528-1:2007规定了锅炉和压力容器结构的性能要求。 ISO 16528-1:2007的目的不是解决锅炉和压力容器的操作、维护和在役检查。 关于压力容器承压部件的几何结构，ISO 16528-1:2007包括用于焊接连接的第一圆周接头的焊接端连接、用于螺纹连接的第一螺纹接头、用于螺栓连接、法兰连接的第一法兰面、用于专有连接或配件的第一密封面以及安全附件（如有必要）。 关于锅炉承压部件的几何结构，ISO 16528-1:2007涵盖了给水入口（包括进水阀）到蒸汽出口（包括出口阀），包括- 可能暴露在过热风险下且无法与主系统、相关安全附件和锅炉连接（如排水、通风、减温等）隔离的连接管。 ISO 16528-1:2007不适用于核部件、铁路和船用锅炉、气瓶或管道系统或机械设备，例如涡轮机和机械外壳。

ISO 16528-1:2007 defines the performance requirements for the construction of boilers and pressure vessels. It is not the intent of ISO 16528-1:2007 to address operation, maintenance and in-service inspection of boilers and pressure vessels. In relation to the geometry of the pressure-containing parts for pressure vessels, ISO 16528-1:2007 includes welding end connection for the first circumferential joint for welded connections, first threaded joint for screwed connections, face of the first flange for bolted, flanged connections, first sealing surface for proprietary connections or fittings and safety accessories, where necessary. In relation to the geometry of pressure-containing parts for boilers, ISO 16528-1:2007 covers feedwater inlet (including the inlet valve) to steam outlet (including the outlet valve), including all inter-connecting tubing that can be exposed to a risk of overheating and cannot be isolated from the main system, associated safety accessories and connections to the boilers involved in services such as draining, venting, desuperheating, etc. ISO 16528-1:2007 does not apply for nuclear components, railway and marine boilers, gas cylinders or piping systems or mechanical equipment, e.g. turbine and machinery casings.
