Note:

A partial examination shall be performed for pressure instruments that are part of safety equipment

for the protection of a pipe or vessel from exceeding allowable limits (safety accessory in accordance

with Pressure Equipment Directive 2014/68/EU, Article 2, point 4).

Pressure equipment with allowable pressure > 200 bar (2900 psi)

Pressure equipment designated for application in every process fluid having a pressurized volume of

<0.1 l and a max. allowable pressure PS > 200 bar (2900 psi) must satisfy the essential safety

requirements set out in Annex I of the Pressure Equipment Directive 2014/68/EU. According to

Article 13 pressure equipment shall be classified by category in accordance with Annex II. Taking

into account the low pressurized volume discussed above, the pressure devices are classed as

category I pressure equipment. These devices must then bear the CE marking.

Reasons:

• Pressure Equipment Directive 2014/68/EU, Article 13, Annex II

• Pressure equipment directive 2014/68/EU, Commission's Working Group "Pressure", Guideline

A-05
