The work of

24、preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental,

25、 in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main t

26、ask of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attent

27、ion is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 8871-3 was prepared by Technical Committee ISO/TC 76, Transfusion, infusion and injection equipment for

28、 medical and pharmaceutical use. Together with the other parts (see below), this part of ISO 8871 cancels and replaces ISO 8871:1990, which has been technically revised. ISO 8871 consists of the following parts, under the general title Elastomeric parts for parenterals and for devices for pharmaceut

29、ical use: Part 1: Extractables in aqueous autoclavates Part 2: Identification and characterization Part 3: Determination of released-particle count Part 4: Biological requirements and test methods Part 5: Functional requirements and testing ENISO88713:2004 vIntroduction When elastomeric closures are

30、 used as primary packaging materials in direct contact with pharmaceutical preparations, the pharmaceutical industry requires, to an increasing extent, definite details from the rubber manufacturer about the presence of particles the closures may release into an injectable. The test methods specifie

31、d in Clauses 3 and 4 make it possible to meet this request. ENISO88713:2004INTENRATIONAL TSANDADR IS-1788 O3:(3002E)1Elastomeric parts for parenterals and for devices for pharmaceutical use Part 3: Determination of released-particle count 1 Scope Elastomeric closures may be superficially contaminate

32、d with visible and subvisible particles, and fragments can also be produced when the closure is pierced by a needle. Such particles may be transferred to pharmaceutical preparations in contact with the elastomeric parts and affect the quality of such preparations. This part of ISO 8871 specifies met

33、hods for the determination of the number of visible and subvisible particles, respectively, detached from elastomeric parts by rinsing. It does not specify particle contamination limits. These will have to be agreed upon between manufacturer and user. 2 Normative references The following referenced

34、documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 3696:1997, Water for analytical laboratory use Specification and test

35、methods 3 Determination of visible-particle count 3.1 Principle This method evaluates the potential for contamination by collecting and counting the particles detached from elastomeric parts on rinsing with water. 3.2 Classification For the purposes of this method, particles are divided into size cl

36、asses as follows, using the longest dimension as the classifying parameter: Class I: 25 m but u 50 m; Class II: 50 m but u 100 m; Class III: 100 m. ENISO88713:20042 3.3 Apparatus and materials 3.3.1 Shaking machine, moving in a horizontal circle of 12 mm 1 mm diameter at 300 min 1to 350 min 1 . 3.3.

37、2 Membrane filters, with a maximum pore size of 0,8 m, provided with grid lines dividing the surface into 3 mm 3 mm squares. NOTE The colour of the filter may significantly affect the test results. If no specific agreement has been made between the interested parties, the basic colour shall be mediu

38、m grey and lie within the following coordinate ranges in the CIE (International Commission on Illumination) system: L* between 60 % and 70 %; a* between 4,7 % and 3,7 %; b* between 4,7 % and 3,7 %. These specifications apply to the grid-imprinted surface of the filter, and assume this surface has a

39、3-mm- square grid made up of green lines. 3.3.3 Clean, wide-mouthed conical flasks, of capacity 300 ml. 3.3.4 Rinse fluid, prepared by dissolving 3 g of commercially available highly concentrated polysorbate 80 (Tween 80) in 10 l of purified water (grade 1 or grade 2 as specified in ISO 3696). 3.3.5

40、 Equipment for supplying the rinse fluid under a suitable pressure, including a terminal filter with a maximum pore size of 1,2 m. 3.3.6 Microscope, magnification about 50, with suitable direct illumination at an angle of 0 to 10 with the microscope stage. 3.4 Preparation for the test 3.4.1 Ensure t

41、hat the environment in which the test is to be carried out is free from extraneous particles which could cause interference. This involves wearing suitable garments and gloves and using a suitable clean-air work station, for example a laminar-flow cabinet meeting the requirements of Class 8 of ISO 1

42、4644-1 (Class 100,000 of US Federal Standard 209E), as well as suitably decontaminated tools and sample-handling equipment. 3.4.2 Carry out a blank test, as follows: Place 50 ml of filtered rinse fluid in a conical flask. Shake for 20 s. Immediately filter the fluid through a membrane filter. Add an

43、other 50 ml portion of rinse fluid to the flask, shake, and filter in the same way. Transfer the filter to the microscope, taking care not to contaminate it. Count the particles on the filter. No more than five particles of Class I and no more than one particle of Class II shall be found. No particl

44、es of Class III shall be present. ENISO88713:2004 3If these requirements are not met, investigate the possible causes of failure, rectify, and repeat the blank test until satisfactory results are obtained. Carry out a blank test both before and after each series of tests. Only when satisfactory valu

45、es are obtained both before and after the series of tests can the results of the tests be considered valid. 3.5 Test Place a number of complete elastomeric parts with a total surface area of approximately 100 cm 2into a conical flask. Add 50 ml of filtered rinse fluid. Shake for 20 s. Immediately fi

46、lter the fluid through a membrane filter. Add another 50 ml portion of rinse fluid to the flask, shake and filter in the same way. Transfer the filter to the microscope, taking care not to contaminate it. Count the particles on the filter. 3.6 Test report For each test, report the following: a) the

47、total surface area of the elastomeric parts tested, and the number of complete parts tested; b) the total particle count in each of the three particle-size classes; c) the particle counts in each of the three classes for the blank tests performed; d) the average particle count in each class per 10 cm 2of surface, rounded to one place of decimals. 4 Determination of subvisible-particle count 4.1 Principle In contact with liquid pharmaceutical preparations, elastomeric parts may release particles having dimensions of 25 m or smaller, and hence not visible to the naked eye.
