It is identical with ISO595-2:1987 “Reusable all-glass or

7、metal-and-glass syringes for medical use Part2: Design, performance requirements and tests” prepared by Technical Committee84 “Syringes for medical use and needles for injection” of the International Organization for Standardization(ISO). Together with BS1263-1, which specifies dimensional requireme

8、nts and is identical with ISO595-1:1986 (as corrected and reprinted1988-05-15), it supersedes BS1263:1946 which is withdrawn. The principal technical differences from the1946 edition which have arisen in adopting ISO595 are the omission of the0.5mL size of syringe, the introduction of the30mL and100

9、mL sizes and an increase in the options permissible for scale graduation. There are, however, many minor changes in the detail of the requirements which are too numerous to summarize. In1994 the European Committee for Standardization(CEN) accepted ISO595-2:1987 as European Standard EN ISO595-2:1994.

10、 As a consequence of implementing the European Standard this BritishStandard is renumbered as BS EN ISO595-2:1995 and any reference to BS1263-2 should be read as a reference to BS EN ISO595-2. Cross-references The Technical Committee has reviewed the provisions of the draft of ISO594-2, to which ref

11、erence is made in the text, and has decided that they are acceptable for use with this standard. When ISO594-2 is published, it is intended to implement it as BS3930-2. Product certification. Users of this BritishStandard are advised to consider thedesirability of third party certification of produc

12、t conformity with this BritishStandard based on testing and continuing surveillance, which may be coupled with assessment of a suppliers quality systems against the appropriate Part of BS5750. Enquiries as to the availability of third party certification schemes will be forwarded by BSI to the Assoc

13、iation of Certification Bodies. If a third party certification scheme does not already exist, users should consider approaching an appropriate body from the list of Association members. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standa

14、rds are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

31、ntrally on the barrel. On syringes having a capacity above2ml, the nozzle shall be situated either centrally or eccentrically on the barrel. If the nozzle is situated eccentrically, the distance between the axis of the nozzle and the nearest point of the internal surface of the barrel shall be not g

32、reater than4mm and the nozzle axis shall be diametrically opposite the scale on the barrel. 4.1.4 In all cases, the axis of the nozzle shall be parallel with the axis of the barrel. 4.1.5 The bore of the nozzle shall be centrally situated in the nozzle. 4.1.6 A means of braking the piston shall be p

33、rovided unless the barrel and packaging are marked to indicate that no means of braking is provided. If a means of braking the piston is provided, it shall be such that when the syringe is held in a vertical position with the nozzle uppermost, the piston shall remain stationary and shall not slide d

34、own under its own weight. The braking action shall be such as not to interfere unduly with the operation of the piston in the syringe. 4.2 All-glass syringes 4.2.1 When examined with normal or corrected vision, the inside of the barrel and the outside of the piston shall have a smooth finish and sha

35、ll be free from surface defects, such as pits, air lines and high spots. NOTEThe surface may be ground. 4.2.2 The glass barrel shall be transparent when wet. 4.2.3 The open end of the barrel shall be slightly bell-mouthed to ensure easy entry of the piston. The open end of the barrel shall have a fl

36、ange which shall act as a finger grip. The flange shall be manufactured so that it prevents the syringe from rolling when placed on a flat surface inclined at10 to the horizontal. The scale shall be readable when the syringe is resting on a level surface. 4.2.4 The end of the piston which is inserte

37、d into the barrel shall have a clearly defined edge to serve as a fiducial line; if this end is bevelled, the edge of the piston in contact with the barrel shall be taken as the fiducial line. NOTE 1The end of the piston and the bottom of the barrel should be shaped so as to minimize dead space. NOT

38、E 2The piston may be either hollow or solid. 4.2.5 The end of the piston that protrudes from the barrel shall be shaped to form a push-button with a flat or concave surface. 4.2.6 If the syringe has a metal nozzle, the nozzle shall be attached so that, when tested in accordance with6.6, no coloured

39、water shall be visible between the nozzle and the barrel. 1) At present at the stage of draft.ENISO595-2:1994 4 BSI 04-2000 4.3 Metal-and-glass syringes 4.3.1 The barrel shall be made of glass; the detachable cap, the nozzle, the plunger and push-button shall be made of metal; and the piston shall b

40、e made of metal or ceramic material. 4.3.2 When examined with normal or corrected vision, the inside of the barrel shall have a smooth finish and shall be free from surface defects, such as pits, air lines and high spots. 4.3.3 The glass barrel shall be transparent when wet. 4.3.4 A flat surface sha

41、ll be provided on the detachable cap or on the nozzle end of the syringe in such a position that the syringe will not roll when it is placed on a surface inclined at10 to the horizontal. The flat surface shall be such that when the syringe rests on a level surface, the scale will be readable. 5 Perf

42、ormance requirements 5.1 Resistance to thermal shock When tested in accordance with6.1, there shall be no fracture of the barrel or other damage to the barrel or the attached fittings. 5.2 Resistance to dry heat When tested in accordance with6.2, the assembled syringe shall operate satisfactorily. T

43、here shall be no signs of fracture in glass components or deterioration of metal components and markings. 5.3 Resistance to corrosion When tested in accordance with6.3, the assembled syringe shall operate satisfactorily and neither the glass nor metal parts of the syringe shall show signs of attack;

44、 the markings shall not show deterioration in their intensity. 5.4 Freedom from leakage between piston and barrel When tested in accordance with6.4, no leakage of water between the piston and the barrel shall be visible. 5.5 Permanence of markings When tested in accordance with6.5, the markings shal

45、l remain legible. 5.6 Freedom from entrapped fluid When tested in accordance with6.6, no coloured water shall be visible in the joints between metal and glass. 5.7 Freedom from striae and strain When examined in accordance with6.7, glass components shall be free from striae and strain. 6 Test method

46、s 6.1 Test procedure for resistance to thermal shock Dismantle the syringe and bring the components to room temperature. Plunge the components into water at99 1 C. After30s, remove the components from water at99 1 C and plunge them into water at room temperature. Remove the components from the water
