24、modification. EN ISO 7886-3:2009 (E) DIN EN ISO 7886-3:2010-01 Introduction ISO 7886 was first published in 1984. It was subsequently decided to divide it into two parts, ISO 7886-1 retaining essentially the scope of ISO 7886:1984, and ISO 7886-2 being applicable to sterile, single-use syringes for
25、use with power-driven pumps. The preparation of this third part of ISO 7886 was recognized as a high priority requirement to prevent the re-use of fixed dose immunization syringes in the developing and transitional countries. Re-use of injection equipment in the absence of sterilization has increasi
26、ngly led to transmission of blood-borne pathogens. The World Health Organization had produced a specification for syringes that are rendered inactive after use (commonly referred to as “auto-disable” syringes). Both the WHO and ISO agreed that an additional part of ISO 7886 would be required to cove
27、r “auto-disable” syringes, whilst leaving in place ISO 7886 Parts 1 and 2 without modification, as a large number of devices in common use would not be intended to comply with the auto-disable properties suggested. This part of ISO 7886 is intended to cover “fixed dose” immunization syringes that ar
28、e rendered inoperable after delivery of the intended dose. These syringes are not covered by Parts 1 and 2 of ISO 7886. It is recognized that syringes designed to reduce the risk of needlestick injuries, in addition to preventing sharps injuries, may also comply with this part of ISO 7886 with regar
29、d to their auto-disable properties, but it is stressed that anti-needlestick properties of syringes are not in themselves addressed in this part of ISO 7886. 4 DIN EN ISO 7886-3:2010-01 EN ISO 7886-3:2009 (E) 1 Scope This part of ISO 7886 specifies the properties and performance of sterile single-us
30、e hypodermic syringes with or without needle, made of plastic materials and stainless steel and intended for the aspiration of vaccines or for the injection of vaccines immediately after filling. Upon delivering a fixed dose of vaccine, the syringe is automatically rendered unusable. This part of IS
31、O 7886 does not specify the design of the auto-disable feature, which is left to the discretion of the manufacturer. This part of ISO 7886 is not applicable to syringes for use with insulin (specified in ISO 8537), syringes made of glass (specified in ISO 595), syringes for use with power-driven syr
32、inge pumps (specified in ISO 7886-2), auto-disable syringes for variable dose delivery and syringes designed to be prefilled. It does not address compatibility with injection fluids/vaccines. NOTE A fourth part of ISO 7886 is being prepared to cover syringes with reuse prevention feature. 2 Normativ

39、O 7886-1:1993 shall apply. 6 Limits for acidity or alkalinity When determined with a laboratory pH meter and using a general purpose electrode, the pH value of an extract prepared in accordance with Annex A shall be within one unit of pH of that of the control fluid. 7 Limits for extractable metals
40、When tested by a recognized microanalytical method, for example by an atomic absorption method, an extract prepared in accordance with Annex A shall, when corrected for the metals content of the control fluid, contain no greater than a combined total of 5 mg/l of lead, tin, zinc and iron. The cadmiu
41、m content of the extract shall, when corrected for the cadmium content of the control fluid, be lower than 0,1 mg/l. 8 Lubricant Clause 8 of ISO 7886-1:1993 and 11.4 of ISO 7864:1993 shall apply. 9 Tolerance on nominal capacity The volume of water at (20 5) C or, for tropical countries (27 5) C expe
42、lled from the syringe when the fiducial line of the piston traverses the full scale (i.e. the intended fixed dose) shall be within the tolerances on the nominal capacity as specified in Table 1. Table 1 Nominal capacity and dead space Nominal capacity Tolerance on nominal capacity Maximum dead space
43、 for integrated and non-integrated needle ml % ml 0,05 u V u 0,2 20 % 0,025 0,2 V u 2 5 % 0,07 10 Graduated scale 10.1 Scale The scale shall have only two markings, the zero line and the nominal capacity line (i.e. the total graduated capacity line). These lines shall be of uniform thickness. They s
44、hall lie in planes at right angles to the axis of the barrel. 10.2 Position of scale 10.4 of ISO 7886-1:1993 shall apply. 7 EN ISO 7886-3:2009 (E) DIN EN ISO 7886-3:2010-01 11 Barrel 11.1 Dimensions The length of the barrel and the design of the auto-disable feature shall be such that the syringe ha
45、s a maximum usable capacity of at least 10 % more than the nominal capacity and a recommended maximum capacity of 20 % more than the nominal capacity. 11.2 Finger grips 11.2 of ISO 7886-1:1993 shall apply. 12 Piston/plunger assembly 12.1 Design The design of the plunger and push-button of the syring
46、e shall be such that, when the barrel is held in one hand, the plunger can be depressed by the thumb of that hand. The piston shall not become detached from the plunger when tested in accordance with Annex B of ISO 8537:1991 for a syringe with integrated needle or in accordance with Annex B of ISO 7
47、886-1:1993 for a syringe without needle. The plunger should be of a length adequate to allow the piston properly to deliver the designated fixed dose. It should not be possible to defeat the auto-disable feature by removing and re-inserting the plunger. The projection of the plunger and the configur
48、ation of the push-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 shall be 8 mm. 1
49、2.2 Fit of the piston in the barrel 12.2 of ISO 7886-1:1993 shall apply. NOTE Annex B gives a suggested test method and performance criteria for the forces required to move the plunger. 12.3 Fiducial line 12.3 of ISO 7886-1:1993 shall apply. 13 Needle 13.1 Integrated needle Syringes with integrated needle shall have a minimum needle union force applied as push or pull in the direction of the needle axis in accordance with ISO 7864:1993. Needle tubing shall be in accordance with ISO 9626. 13.2 Non-integrated needle If a non-integrated need
