欧盟Directive 2014/68/EU指令《压力设备的市场准入》 (PED)

The Pressure Equipment Directive (PED) 2014/68/EU (replaced (PED) 97/23/EC in 2016) is a fundamental piece of European legislation related to the safety of pressure equipment throughout Europe. The directive entered into force on 20 July 2016 and replaced its predecessor (PED) 97/23/EC.

压力设备指令(PED) 2014/68/EU是欧洲法规体系中与全欧洲压力设备安全相关的一项基础构件。其于2016720日生效,并取代了此前的(PED)97/23/EC

The Pressure Equipment Directive (PED) applies to the design, manufacture and conformity assessment of pressure equipment and assemblies with a maximum allowable pressure greater than 0.5 bar gauge including vessels, piping, safety accessories and pressure accessories.

压力设备指令(PED) 2014/68/EU适用于最大允许压力大于0.5 bar表压的压力设备和组件的设计、制造和合规性评估, 包括容器、管道、安全附件和压力附件。

Not all pressure equipment is covered by this directive as The Transportable Pressure Equipment Directive and the Simple Pressure Vessels Directive both cover certain equipment and products which present a relatively low hazard from pressurization. There are also hazards and risks that are covered by other directives, e.g. Machinery Equipment Directive, ATEX Directive, Low Voltage Directive or the Electro Magnetic Compatibility Directive.

并非所有压力设备都包括于本指令, 比如《可运输压力设备指令》和《简易压力容器指令》两者就涵盖了其它某些设备和产品, 这些设备和产品的加压危害相对较低。还有其它指令涵盖别的危害和风险, 例如机械设备指令、ATEX 指令、低电压指令或电磁兼容指令等。

The purpose of the PED is to provide for a legal structure whereby pressure equipment can be manufactured and sold throughout the European Union without having to go through a local approval regime in every member state. The means by which this is achieved is to ensure common standards of safety in all pressure equipment sold within the European Economic Area. Manufacturers are therefore able to meet the requirements for approval in any member state of the EU, and do not have to repeat the process when selling goods in any other state. 

PED 指令的目的是提供一个法律框架, 使压力设备可以在整个欧盟范围内制造和销售, 而不必经过每个成员国各自的审批体系。实现这一目标的手段是确保在欧洲经济区内销售的所有压力设备具备统一的安全标准。制造商据此可以满足欧盟任何成员国的审批标准, 并可在任何其它成员国销售产品时不必重复此一程序。
