17、SO13897:2004ISO 13897:2003(E) iiiForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body inte
18、rested 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, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnica
19、l 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 task of technical committees is to prepare International Standards. Draft International Standards adopted by the t
20、echnical 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. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. I
21、SO shall not be held responsible for identifying any or all such patent rights. ISO 13897 was prepared by Technical Committee ISO/TC 106, Dentistry, Subcommittee SC 6, Dental equipment. ENISO13897:2004ISO 13897:2003(E) iv Introduction In order to produce dental amalgam, electrically powered amalgama
22、tors as described in ISO 7488 are primarily used for mixing (trituration) of amalgam alloys with mercury. In many amalgamators, a removable capsule is used to contain the alloy and mercury. Although the capsule must be considered as part of the amalgamator when in use or under test, the requirements
23、 for capsules are not dealt with in ISO 7488. These requirements are the subject of this International Standard. ENISO13897:2004INTENRATIONAL TSANDADR IS:79831 O3002(E)1Dentistry Amalgam capsules 1 Scope This International Standard specifies requirements and test methods for predosed capsules and fo
24、r reusable capsules used for mixing dental amalgam alloys and mercury. 2 Normative references The following referenced 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
25、document (including any amendments) applies.

27、ay that premature contact is prevented 3.2 self-activating capsule predosed capsule in which contact between the alloy powder and mercury occurs automatically during amalgamation 3.3 activation action that renders the contained alloy powder and mercury mixable 4 Classification Amalgam capsules cover
28、ed by this International Standard shall be classified as follows, according to the reusability of the mixing capsule: Type 1: predosed mixing capsule Type 2: reusable mixing capsule ENISO13897:2004ISO 13897:2003(E) 2 5 Requirements 5.1 Package and capsule contamination The packaging container and th
29、e outer surface of Type 1 capsules shall be free of mercury and/or alloy powder contamination when tested in accordance with 7.1. 5.2 Dimensions 5.2.1 Length tolerance The overall length of activated Type 1 capsules and of Type 2 capsules shall be within 1 mm of the length specified by the manufactu
30、rer. Testing shall be carried out in accordance with 7.2. 5.2.2 Diameter tolerance The maximum external diameter of Type 1 and Type 2 capsules shall be within 0,5 mm of the diameter specified by the manufacturer. Testing shall be carried out in accordance with 7.2. 5.3 Loss of mass 5.3.1 General The
31、 loss in mass for Type 1 and Type 2 capsules during amalgamation shall not exceed 0,5 mg. Testing shall be carried out in accordance with 7.3. 5.3.2 Type 1 capsules Type 1 capsules shall contain dental amalgam alloy and dental mercury which meet the following requirements: the dental amalgam alloy s
32、hall conform to ISO 1559; the dental mercury shall conform to ISO 1560. 5.3.3 Type 2 capsules Type 2 capsules shall be tested using dental amalgam alloy and dental mercury which meet the following requirements: the dental amalgam alloy shall conform to ISO 1559; the dental mercury shall conform to I
33、SO 1560. 5.4 Mercury and alloy retention The mass of the retained material found within Type 1 and Type 2 capsules after amalgamation shall not exceed 1 % of the mass of alloy and mercury. Testing shall be carried out in accordance with 7.4. ENISO13897:2004ISO 13897:2003(E) 36 Sampling A sufficient
34、number of capsules to perform all tests shall be obtained from a single manufactured batch. 7 Test methods 7.1 Package and capsule contamination (Type 1 capsules only) 7.1.1 Apparatus 7.1.1.1 Stereomicroscope with 8x magnification. 7.1.2 Procedure Visually examine both the primary package or contain
35、er and 25 randomly selected capsules under a magnification of 8. 7.2 Dimensions 7.2.1 Apparatus 7.2.1.1 Micrometer or an optical comparator, having an accuracy of 0,05 mm. 7.2.2 Procedure Test 10 samples of the capsules. For Type 1 capsules, other than self-activating units, activate each sample but
36、 do not amalgamate before the test. Measure and record the overall length of each capsule. Determine the location of the largest diameter, measure and record each result. 7.2.3 Pass/fail determination The length and diameter of all 10 capsules shall meet the requirements specified in 5.2.1 and 5.2.2
37、. 7.3 Loss of mass 7.3.1 Apparatus 7.3.1.1 Amalgamator in accordance with ISO 7488 and tested using a strobe light as specified in ISO 7488:1991, 7.3, to ensure that the stated oscillation frequency is obtained. 7.3.1.2 Laboratory balance with an accuracy of 0,05 mg. 7.3.1.3 Pliers, needle-nosed typ
38、e. 7.3.1.4 Brush having soft bristles. 7.3.2 Procedure for Type 1 capsules Select five capsules at random and test each as follows. Before amalgamation, remove any loose material from the surface of each capsule and weigh each capsule to the nearest 0,1 mg. Amalgamate in accordance with ISO 1559:199
39、5, 6.1.2. After amalgamation, allow each capsule to cool to room temperature for 1 h and then reweigh it to the nearest 0,1 mg. 7.3.3 Procedure for Type 2 capsules Fill each of five randomly selected capsules with 600 mg alloy powder and add the mass of mercury specified by the manufacturer for this
40、 mass of alloy. Close the capsule, remove any loose material from the surface, and weigh to the nearest 0,1 mg. Amalgamate in accordance with ISO 1559:1995, 6.1.2. After amalgamation, ENISO13897:2004ISO 13897:2003(E) 4 allow the capsule to cool to room temperature for 1 h and then reweigh it to the
41、nearest 0,1 mg. Using the same capsules, repeat the test for each capsule four more times. 7.3.4 Calculation of results Calculate the loss of mass as capsule mass before amalgamation minus capsule mass after amalgamation. 7.3.5 Pass/fail determinations 7.3.5.1 Type 1 capsules Five out of five capsul
42、es or 14 out of the 15 capsules shall meet the requirements of 5.3. 7.3.5.2 Type 2 capsules 7.4 Mercury/alloy retention 7.4.1 Type 1 capsules 7.4.1.1 Procedure Use the apparatus specified in 7.3.1. Select five capsules at random and test each as follows. Weigh each capsule to the nearest 1 mg as m 1
43、 . Amalgamate for the time and at the frequency recommended by the alloys manufacturer. Remove the capsule from the amalgamator, open the capsule, and empty the amalgam into a receptacle. Weigh the capsule components to the nearest 1 mg as m 2 . If necessary, use pliers to separate all capsule compo
44、nents and then brush out all retained material. Reweigh the capsule components to the nearest 1 mg as m 3 . 7.4.1.2 Calculation of results The difference (m 2 m 3 ) is the mass of alloy and mercury retained. Calculate the retained mass of alloy and mercury, m, as percentage of the initial mass of al
45、loy and mercury for each capsule to the nearest 0,05 %, using the following equation () 23 13 100 () mm m mm = where m 1is the capsule mass before amalgamation; m 2is the mass of the capsule components after amalgamation; m 3is the mass of the capsule components after amalgamation and after brushing
46、 out all retained material. 7.4.1.3 Pass/fail determinations If one of five capsules fails the test, test 10 more capsules. Five out of five capsules or 14 out of the 15 capsules shall meet the requirements of 5.4. IC.11 S.06001 feR. .oN ISO :79831/3002.roC:1(3002)E ISA 3002 Oll irthgs serdevre NIRE
