COPYRIGHT DIN DEUTSCHES Institut Fur Normung E.V.- EnglishLicensed by Information Handling ServicesPage 3 EN 1707:1996 1 Scope This European S
19、tandard specifies requirements for conical lock fittings with a 6 % (Luer) taper for use with hypodermic syringes and needles and with certain other apparatus for medical use e. g . transfusion equipment. The requirements apply to fittings made of rigid and of semi-rigid materials and include test m
20、ethods, but exclude provision for more flexible or elastomeric materials. NOTE 1. It is not practicable to define the characteristics of rigid or semi-rigid materials with precision, but glass and metal may be considered as typical rigid materiais. In contrast many plastics materials may be regarded
21、 as semi-rigid. NOTE 2. The Luer lock fitting was designed for use at pressures of the order of 30 kPa or lower. Its use in other applications may require consideration to establish its suitability. 2 Normative references This European Standard incorporates by dated or undated reference, provisions

For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amend

26、 Rigid materials The dimensions of male and female lock fittings made of rigid materials shall be as shown in figures 1 to 4 and as given in table 1. 3.2.2 Semi-rigid materials For fittings made using semi-rigid materials, because of their nature, it is not possible to specify the fittings dimension
27、s accurately. Design and dimensions of fittings made of these materials may vary from those designated in figures 1 and 4 and given in table 1. However, the fittings shall meet the specified performance requirements when fitted to reference fittings as specified in 5.1. 4 Requirements 4.1 Gauging Wh

31、nce fitting in accordance with 5.6, the following criterion, as appropriate, shall be satisfied: a) rigid fittings: no resistance shall be observed until the taper of the fitting under test and the reference fitting fit together securely; b) semi-rigid fittings: a satisfactory fit shall be achieved
32、by applying an axial force not exceeding 20 N while applying a torque not exceeding 0,08 Nm. 4.6 Resistance to overriding When the fitting is tested in accordance with 5.7, the reference fitting shall not override the threads or lugs of the fitting under test. 4.7 Stress cracking When the Fitting is
33、 tested in accordance with 5.8, there shall be no evidence of stress cracking of the fitting. NOTE. Materials used for fittings should be resistant to stress cracking in environments likely to be encountered in use (e.g. when in contact with solvents, surface active agents, etc.).

The reference fittings shall be manufactured from harden
35、ed corrosion-resistant materials with a surface roughness value, $, not exceeding 0,8 pm (in accordance with IS0 468) on critical surfaces. The dimensions of the conical part of these reference fittings shall be in accordance with those specified in figures 4 and 5 of EN 20594- 1 1993. 5.2 Liquid le
36、akage from fitting assembly under pressure 5.2.1 Connect the fitting to be tested to a reference fitting, the dimensions of which are in accordance with those shown in figures 5 or 7, as appropriate. Dry both fittings. Assemble the fittings by applying an axial force not exceeding 27,5 N while apply
37、ing a torque not exceeding 0,12 Nm. 5.2.2 Introduce water into the assembly and expel the air. Ensure that the outside of the fitting assembly is dry. 5.2.3 With the axis of the lock fitting horizontal, seal the assembly outlet and bring the internal water pressure to an effective pressure of 300 kP
38、a to 330 kPa and maintain the pressure for 30 s. If the intended use is on a device employing higher pressure, then this shall be taken into consideration during testing. 5.3 Air leakage into fitting assembly during aspiration 5.3.1 General Other validated test methods (e.g. methods involving automa
39、tic testing) may be used if good correlation is shown with the reference test given in 5.3.2 or 5.3.3.
