Guideline B-09
The maximum allowable pressure (PS) of the vessel and the total volume of the vessel shall be used according to Article 13 paragraph 2
Guideline B-10
Article 13, paragraph 2 states that the classification shall be on the basis of the fluid which requires the higher category. The total volume (V) of the vessel, as defined in Article 2 (10), shall be used to determine the conformity assessment category, not the actual volume occupied by the individual fluids at any particular […]
Guideline B-19
They constitute two chambers of the same vessel. Technical requirements and conformity assessment procedure to be applied are determined as follows: The technical requirements to be applied to the common boundary are those of the highest category of the two chambers. Hazard analysis of individual chambers must take account of the effect of any perceived […]
Guideline B-27
The classification shall be determined by the fluid which gives the highest category taking into account the starting, intermediate and final fluids, which could arise from all reasonably foreseeable conditions. See also PED Guidelines B-21
Guideline B-34
Hermetically sealed refrigeration compressors are pressure vessels. Usually, a compressor is composed of two chambers : the low pressure side PS1, the volume of which is V1, and the high pressure side PS2, the volume of which is V2. The equalizing pressure during standstill is PS3 (always higher than PS1). The category is the higher […]
