Guideline A-05
Vessels referred to inArticle 4 (volume lessthan or equal to 0,1 litre) Table inAnnex II Category(Volume less than or equal to 0,1 litre) 1.(a)(i) first indent 1 If PS ≤ 200 bar, then Article 4.3appliesotherwise see point 3 below 1.(a)(i) second indent 2 If PS ≤ 1000 bar, then Article 4.3appliesotherwise see point 3 below […]
Guideline A-34
Yes, if the PS of the compressed air is greater than 0,5 bar. The PS of com- pressed air and internal volume of the tank determine the category according to the table 2 of Annex II. Reason:Slurry tankers are not excluded from the scope of the PED due to Article 1 paragraph 2 (s). They […]
Guideline B-03
Vessels for super-heated water are covered by article 4, paragraph 1(a)(i), second indent and Annex II table 2 applies. Piping for super-heated water is covered by article 4, paragraph 1(c)(i), second indent and Annex II table 7 applies. These statements are applicable to unheated vessels or pipes with temperatures > 110° C. Fired or otherwise […]
Guideline B-11
Article 14 paragraph 3 states that manufacturers can choose to apply one of the procedures which apply to a higher category if available. The words ‘if available’ make it clear that if an item of pressure equipment was classified as category IV, then a module from a higher category is not available. Even for those […]
Guideline B-13
Guideline B-23
This pressure equipment shall be considered as a heat exchanger containing super-heated or hot water (with or without additives) Only when a solar panel in its entirety is designed to withstand the highest possible temperatures (stagnation conditions are within the normal operation range), a risk of overheating does not occur (see PED Guideline B-22). As […]
Guideline B-25
No The classification of a pressure equipment is based on the following factors: These factors determine the table of Annex II to be used. In the appropriate table, the maximum allowable pressure and the volume for vessels or the maximum allowable pressure and the nominal size DN for piping determines the Category of the equipment. […]
Guideline B-28
For such a piping the maximum DN used for that item of pressure equipment shall be the basis for the classification. The manufacturer shall show the extent of piping for that item in the technical documentation. Note:The term a “piping” as used above means an item of pressure equipment, and not an “assembly” as defined […]
Guideline B-33
The single items of pressure equipment shall be classified according to their inherent characteristics (PS, V, DN, …). However, their integration in the safety chain is conducted using a category IV conformity assessment module or a module for the category of the equipment for which the chain is specifically designed. When items of pressure equipment […]
