34、 five RPD head forms used for laboratory testing are based on the anthropometric measurements and averaged head dimensions specified in ISO/TS 16976-2. Neck lengths are elongated and diameters are sized in accordance with anthropometric data to permit the sealing of RPD interfaces with neck dams. Al

35、l RPD head forms contain the same sized trachea tube assembly so that the connection between the neck and an RPD torso or alternative fixture is identical for all sizes. For the purpose of acoustic measurements, the ears are flat and the position of the microphones is marked. For the purposes of fie

36、ld of vision measurements, the positions of the pupils are marked to permit the fixing of light sources.

37、and side view4.1.2 RPD head form CAD filesThe RPD head forms are defined by the three-dimensional computer-aided design (CAD) files derived from the dimensions specified in ISO/TS 16976-2. CAD files of the RPD head forms are available from the source given in Reference 3 and these will permit the pr

38、oduction of RPD head forms of the correct dimensions. The CAD files represent the final surface geometry of the RPD head forms 1 to 5.Each manufactured RPD head form shall be marked on the top or the back of the head with the head form number consistent with key in Figure 1.The conformance of the ma

39、nufactured RPD head forms to the CAD file can be determined by reference to the table of reference dimensions marked by small indents, contained in the CAD files, see Figure 2, key X. The reference indents are located at the left and right side of the RPD head forms, the left and right side of the n

40、ose and the centre of the pupils. The deviation of the manufactured RPD head form from the source CAD file data shall be no more than 1 mm in any of the referenced dimension.

45、on for the RPD head form for the flame and thermal exposure tests shall be metal, ceramic or other heat-tolerant material and the surface finish shall be smooth.4.1.4 Trachea tube assembly and interface connectionsThe same trachea tube assembly is used in all five RPD head forms. The trachea tube co

46、mponent shall be manufactured from stainless steel. The trachea tube assembly may be designed so that it can be inserted into hollow RPD head forms via the neck opening or be manufactured such that all components of the trachea tube assembly are permanently fixed. The connection between the mouth op

47、ening and the trachea tube assembly shall be sealed. The connection between the RPD head form and RPD torso or alternative fixture is achieved using a mechanical socket (see Figures 3 to 5).The volume of the trachea tube assembly and connecting tubes within the RPD head form and RPD torso or alterna

48、tive fixture up to the position of the control valves shall be (500 150) ml. Figure 3 a) shows the trachea tube assembly inside the RPD head form 1 positioned on an alternative fixture.
