EEMUA 211涉及设计规范中未涉及的各种不同情况下的压力容器规范。它根据用户的经验总结了压力容器设计、制造和测试的实践经验。该指南检查了可放弃重复焊后热处理（PWHT）的情况，描述了评估现有和新压力容器异常内部压力的方法，涵盖了喷嘴规格和可靠性的改进，给出了蠕变的基本评估，以及本第三版的新增内容，为压力设备中的疲劳问题提供一些背景知识。

EEMUA 211 deals with the specification of pressure vessels for a variety of different circumstances not addressed in design codes. It brings together the practical lessons learnt about design, manufacturing and testing of pressure vessels based on users' experience. The guidance examines the circumstances under which repeat post-weld heat treatment (PWHT) may be waived, describes methods for assessing both existing and new pressure vessels for exceptional internal pressures, covers improvements in the specification and reliability of nozzles, gives a basic appreciation of creep and, new for this third edition, provides some background to the issues of fatigue in pressure equipment.
