prEN 14931:2006 (E) Annex A (normative) Adaptor set for compression chambers A.1 General Compression chambers with entrances of various dimensions are used. To achieve the interchangeability of compression chambers a common STANAG flange was agreed. An adaptor set consists of a female coupling (locking ring) and a male coupling (reducing ring). A.2 Standard connections or adaptor set required for the interchangeability of compression chambers Chamber adaptor sets as described in A.3 and A.4 will be adopted for use between fixed multi-personnel compressions chambers and transportable compression chambers and be provided with a safety interlock preferably in the main chamber. These adaptor sets allow for a transportable compression chamber provided with a reducing ring as described in A.4 to be locked onto the fixed multi-place chamber, for the door of the transportable chamber to be opened, and if necessary removed, and for the patient to be transferred without loss of pressure. They should be clearly marked to indicate that they are NATO compatible adaptors, and are to be manufactured to withstand a working pressure of at least 500 kPa (5 bar, 71 psi) and a test pressure of at least 750 kPa (7,5 bar, 107 psi). The minimum dimensions required for the fixed multi-place chamber are given in A.5, and for the transportable chamber in A.6. The required free space to connect an adapter and / or a transport chamber are to be examined regarding to the respective system configuration. 25
