压力设备指令(PED)
普遍的PED问题

PED是什么?

PED stands for pressure equipment directive. In an effort to harmonize national legislation regarding the design, manufacture and test of pressure vessels, the European Parliament and the Council of the European Union adopted the PED. The PED went into effect on May 29, 2002, setting forth that all pressure vessels manufactured and placed on the market in the EU after such date would be subject to the requirements of the PED.

是DADCO符合PED吗?

Yes, DADCO is certified by TÜV CERT, TÜV Rheinland/Berlin-Brandenburg as conforming to the PED. All DADCO nitrogen gas springs are compliant and those for sale in the EU, required by the PED to carry the CE mark, are marked CE 0035. According to the PED, the CE mark may only be used on those cylinders that fall within specified categories according to the PED (i.e. smaller sizes do not receive the CE mark).

符合PED需要变更DADCO氮气弹簧的设计了吗?

No, we were not required to make any changes to the DADCO gas spring design to be compliant with the PED.

PED的分类是给DADCO核准的?

DADCO is approved by TÜV CERT, TÜV Rheinland/Berlin-Brandenburg under PED, Module A1.

关于维修或改装旧DADCO氮气弹簧,有没有任何问题?

No, the ability to repair or retrofit existing DADCO cylinders will still be as easy as it has always been. All of the components of PED conforming gas springs are the same as those manufactured prior to the establishment of the PED. The best path for maintenance safety is proper training, adherence to published maintenance instructions, and use of parts from the same OEM.

PED要求生产材料的审核吗?

Yes, the PED requires pressure vessel materials to have a high level of traceability. These materials must also conform to impact and elongation requirements. All materials used in the 90.10 Series (ISO) already conformed to this requirement.

带CE标记的DADCO氮气弹簧与没带CE标记的弹簧有没有区别

The design, processing, materials and level of quality are the same. The CE marked cylinders are subject to additional weld and pressure tests as required by the PED. The CE mark is only required on those products being placed on the market in the EU, the CE mark is available as an option for domestic shipments.
