They shall lie in planes at right angles to the axis of the barrel. 10.1.4 The graduation lines shal
20、l be evenly spaced along the longitudinal axis between the zero gradu- ation line and the line for the total graduated capacity. 10.1.5 When the syringe is held vertically, the ends of all graduation lines of similar length shall be verti- cally beneath each other. 10.1.6 The lengths of the short gr
21、aduation lines on each scale shall be approximately half the length of the long tines. Examples of scales and the numbering of graduation lines are shown in figure2.

In addition, the line denoting the nomina
23、l capacity or the lines denot- ing the nominal capacity and the total graduated ca- pacity, if these differ, shall be numbered. Examples of scale numbering are shown in figurez. 10.2.2 When the syringe is held vertically with the conical tip uppermost and with the scale to the front, the numbers sha
24、ll appear vertical on the scale and in a position such that they would be bisected by a prolongation of the graduation lines to which they re- late. The numbers shall be close to, but shall not touch, the ends of the graduation lines to which they relate. 10.3 Overall length of scale to nominal capa

26、n a quarter of the 1- :E smallest scale interval. 11 Barrel 11.1 Dimensions The length of the barrel shall be such that the syringe than the nominal capacity. has a maximum usable capacity of at least 1 O % more 11.2 Finger grips The open end of the barrel shall be provided with fin- ger grips that
27、shall ensure that the syringe will not roll more than 180“ when it is placed on a flat surface at an angle of lo“ to the horizontal. The finger grips shall be free from flash and sharp edges. Finger grips should be of adequate size, shape and strength for the intended purpose and should enable the s
28、yringe to be held securely during use. 12 Pistonlplunger assembly 12.1 Design The design of the plunger and push-button of the syringe shall be such that, when the barrel is held in one hand, the plunger can be depressed by the thumb of that hand. When tested in accordance with annex B , the piston
29、shall not become detached from the plunger. The plunger should be of a length adequate to allow the piston to traverse the full length of the barrel, but it should not be possible easily to withdraw the plunger completely from the barrel. The projection of the plunger and the configuration of the pu
30、sh-button should be such as to allow the plunger to be operated without difficulty. When the fiducial line of the piston coincides with the zero graduation line, the preferred minimum length of the plunger from the surface of the finger grips nearer to the push-button should be: a) 8 mm for syringes
31、 of nominal capacity up to but excluding 2 ml; b) 9 mm for syringes of nominal capacity of 2 ml up to but excluding 5 ml; c) 12,5 mm for syringes of nominal capacity of 5 ml and greater. 12.2 Fit of piston in barrel When the syringe is filled with water and held verti- cally with first one end and t
32、hen the other end up- permost, the plunger shall not move by reason of its own mass. NOTE 5 A suggested test method and performance cri- teria for the forces required to move the plunger are given in annex G. It is recommended that this test be used to generate data on which to decide whether to mak
33、e this test mandatory in a future revision of this part of IS0 7886. 12.3 Fiducial line There shall be a visible and defined edge serving as the fiducial line at the end of the piston. The fiducial line shall be in contact with the inner surface of the barrel. 13 Nozzle 13.1 Conical fitting The male
34、 conical fitting of the syringe nozzle shall be in accordance with IS0 594-1. If the syringe has a locking fitting, it shall be in ac- cordance with IS0 594-2. 13.2 Position of nozzle on end of barrel 13.2.1 On syringes of nominal capacity up to but not including 5 ml, the syringe nozzle shall t 3 s
35、ituated centrally, .e. it shall be coaxial with the barrel. 5 COPYRIGHT European Committee for StandardizationLicensed by Information Handling Services13.2.2 On syringes of nominal capacity 5 ml and greater, the syringe nozzle shall be situated either centrally or eccentrically. 13.2.3 If the syring
36、e nozzle is eccentric, its axis shall be vertically below the axis of the barrel when the syringe is lying on a flat surface with the scale up- permost. The distance between the axis of the nozzle and the nearest point on the internal surface of the bore of the barrel shall be not greater than 4,5 m
37、m. 13.3 Nozzle lumen The nozzle lumen shall have a diameter of not less than 1.2 mm. 14 Performance 14.1 Dead space When tested in accordance with annex C, the volume of liquid contained in the barrel and the nozzle when the piston is fully inserted shall be as given in table l. 14.2 Freedom from ai
38、r and liquid leakage past piston When tested in accordance with annex D, there shall be no leakage of water past the piston or seal(s1. When tested in accordance with annex B, there shall be no leakage of air past the piston or seal(s), and there shall be no fall in the manometer reading. 15 Packagi
39、ng 15.1 Primary container Each hypodermic syringe shall be sealed in a primary container. The materials of the container should not have detri- mental effects on the contents. The material and de sign of the container should be such as to ensure: a) the maintenance of sterility of the contents under
40、 dry, clean and adequately ventilated storage con- ditions; b) the minimum risk of contamination of the contents during opening of the container and removal of the contents; c) adequate protection of the contents during normal handling, transit and storage; d) that once opened, the container cannot
41、be easily resealed, and it should be obvious that the con- tainer has been opened. 15.2 Secondary container One or more primary containers shall be packaged in a secondary container. The secondary container should be sufficiently robust to protect the contents during handling, transit and storage. O
42、ne or more secondary containers may be packaged in a storage and/or transit container. 16 Labelling 16.1 Primary container The primary container shall be marked with at least the following information: a) a description of the contents, including the nomi- nal capacity and the type of nozzle; b) the
