23、andard, hose connectors for air driven dental handpieces are classified into the following four types: Type 1: connector with two or three outlets and connection thread 9/16 40 UNS; Type 2: connector with four or five outlets and connection thread 0,555 36 UNS; Type 3: connector with four outlets an
24、d electrical contacts and connection thread 0,555 36 UNS; Type 4: connector with three outlets and connection thread M12 0,5, in accordance with ISO 261. DIN EN ISO 9168:2009-10 EN ISO 9168:2009 (E) 45 Requirements 5.1 General Hose connectors for air driven dental handpieces are specific parts of de
25、ntal handpieces. Requirements for dental handpieces are specified in the relevant product standards. NOTE Relevant product standards for dental handpieces are e.g. ISO 7785-1, ISO 13294 and ISO 15606. 5.2 Dimensions The dimensions, the outlet configuration and the use of the outlets shall be as spec
26、ified in Figure 1, Figure 2, Figure 3 and Figure 4. The thread characteristics for Type 1, Type 2 and Type 3 shall be as specified in Table 1. The thread characteristics for Type 4 (M12 0,5) shall be in accordance with ISO 261. Testing shall be carried out in accordance with 7.1. 5.3 Resistance to r
27、eprocessing Hose connectors shall be capable of withstanding a minimum of 250 reprocessing cycles as defined in the manufacturers instructions for use without deterioration in appearance or performance. Quick connectors with and without lights supply, which are not permanently fixed to the instrumen
28、t, shall be capable of withstanding the reprocessing procedure as given in the manufacturers instructions. In this case the requirements of ISO 7494-1 are applicable. Testing shall be carried out in accordance with 7.2. DIN EN ISO 9168:2009-10 EN ISO 9168:2009 (E) 5 Dimensions in millimetres a) Hand
