Guideline A-11
1. Article 1 paragraph 2 (j) excludes pressurized equipment comprising casings or machinery from the scope of the PED a) if this equipment is primarily dimensioned for loads other than pressure, i.e. for which pressure is not the significant design factor and b) if it is primarily designed to move or rotate or fulfil other […]
Guideline A-12
Note:In application of the definition of “volume” given in article 2 paragraph 10, the volume of the mechanical parts is to be excluded from the volume to be taken into account but not the volume of the oil contained.
Guideline A-19
For fluid power components and systems using liquids or gases of group 2 according to Article 13 paragraph 1 (b), the following applies : 1. Excluded from PED 1.1. due to exclusion of Article 1 paragraph 2 (f) (e.g. machinery directive) 1.2. due to exclusion of Article 1 paragraph 2 (j) (refer to guideline A-11) […]
Guideline A-31
NGV filling stations are covered by PED. They are not excluded by Article 1 paragraph 2 (a) as annexed equipment designed specifically for pipelines. However, compressors are considered machinery as specified under Article 1 paragraph 2 (j) and thus may be excluded from PED (see PED Guideline A-11).
Guideline A-50
The flare tip is covered by the PED, when the internal pressure exceeds 0,5 bar, in which case it is a pressure accessory. Note 1: A flare (or flare system) can be considered as two parts: the lower part, which essentially comprises discharge piping and the upper part, at the extremity of the piping (usually […]
Guideline A-53
Yes. Reason:Even if thermal, dynamic and other non-pressure loads are important for the design of dryer rolls, for most pressure is a significant design factor when dimensioning the equipment. Note 1:However some dryer rolls with a specific design such as the incorporation of many small holes may be excluded from the PED on the basis […]
