This European Standard shall be given the status o

Attention is drawn to the possibility that some of the elements of this document may be the subject o

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this

26、nited Kingdom. Endorsement notice The text of ISO 3630-1:2008 has been approved by CEN as a EN ISO 3630-1:2008 without any modification. Introduction The reorganization of ISO 3630 is intended to present the requirements and test methods for root-canal instruments in an orderly manner. This part of
27、ISO 3630 defines general requirements and test methods. Subsequent parts provide the specific requirements and test methods, if applicable, for two areas of endodontic procedures. These parts are enlargers, condensers and auxiliary instruments. With current use of nickel-titanium (Ni-Ti) alloys for
28、manufacture of root canal instruments a need for adequate expertise in their safe use is recommended. Instruments made of Ni-Ti can be easily broken near the tip if manufacturers cautions are not understood and practiced. This part of ISO 3630 does not attempt to provide information for proper use o
29、f any instruments. The sizes of the root-canal obturating points (cones) specified in ISO 68774have to be aligned with the corresponding sizes for root-canal instruments specified in ISO 3630. 4 DIN EN ISO 3630-1:2008-04 EN ISO 3630-1:2008 (E) 1 Scope This part of ISO 3630 specifies general requirem
30、ents and test methods for root-canal instruments used for endodontic purposes, e.g. enlargers, shaping and cleaning instruments, condensers, and accessory instruments. In addition it covers general size designations, colour coding, packaging and identification symbols. 2 Normative references The fol

42、For the purposes of this document, the following symbols apply. d1diameter of the projection of the working part at the tip end (reference size); d2diameter at length l2; d3diameter at the end of minimum length of working part, length l3; l1tip length; l2length for measuring point d2; l3length for m
43、easuring point d3and minimum length of working part; l4length of operative part. 4 Classification For the purposes of this document, root-canal instruments are classified according to the shape and taper of the tip size (see Figure 1) as follows. Type 1: standard-sized instruments (taper = 2 %); Typ
44、e 2: taper-sized instruments (taper other than 2 %); Type 3: shape-sized instruments (arc shape); Type 4: non-taper-sized instruments (zero taper); Type 5: non-uniform taper-sized instruments (more than one taper). 5 Requirements 5.1 General Specific root-canal instrument types, such as enlargers, h
45、ave unique shapes which are not included here. These cases are covered in ISO 3630-2 and ISO 3630-3. 5.2 Type 1: standard-sized instruments 5.2.1 Length The length of the working part, l3, shall be a minimum of 16 mm unless otherwise specified by the manufacturer. The lengths of the working part, wh
46、en specified, and of the operative part, l4, shall be within 0,5 mm of the specified lengths. Test in accordance with 7.3. 7 EN ISO 3630-1:2008 (E) DIN EN ISO 3630-1:2008-04 Figure 1 Dimensions and locations for Type 1 (standard-sized instruments; taper = 2 %) 5.2.2 Size designation and diameters Ta
47、ble 1 gives the nominal sizes and dimensions for the working part to be used for Type 1 (standard-sized instruments). Tip sizes (d1) other than those listed in Table 1 are permitted. Figure 1 shows the position of the diameters and lengths for all Type 1 root-canal instruments. The nominal sizes sha
48、ll correspond to the values of the extended diameters at the tip of the working part in hundredths of a millimetre. NOTE The designation (code number) with three digits is part of the 15-digit identification number specified in ISO 6360-1 and ISO 6360-2. 5.2.3 Colour designation Table 1 gives the co
49、lour designation for each size of Type 1 instrument. These colours are used on the handle or shank and specify the size identification of the working part. Colours of sizes not included in Table 1 are at the discretion of the manufacturer. 5.2.4 Tip shape The shape of the tip is at the discretion of the manufacturer. 5.2.5 Tip length and angle The tip length shall be within the limits specified by the minimum and maximum angle (l1min. to l1max.) as shown in Figure 1.
