This International Standard specifies general requirements and test methods for caps made of aluminiumplastics combinations in accordance with ISO 8536-7 or ISO 8362-6 intended for use respectively on infusion bottles as specified in ISO 8536-1 and/or injection bottles as specified in ISO 8362-1 and ISO 8362-4. The purpose of this International Standard is to specify caps that provide: a) guarantee of originality of the closure up to the point of administration; b) compression of the sealing element (rubber closure) on to the sealing surfaces of the infusion and/or injection bottles; c) protection of the sealing element against soiling and mechanical damage; d) simple and injury-free opening of the closure in order to expose the penetration area of the rubber closure and/or to permit total removal of the cap.
