21、AL COMMISSION _ FIBRE OPTIC INTERCONNECTING DEVICES AND PASSIVE COMPONENTS BASIC TEST AND MEASUREMENT PROCEDURES Part 3-46: Measurement Bore diameter for guide pin in MT ferrules FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprisin
22、g all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards
23、, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparato
24、ry work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizatio
25、ns. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of rec
26、ommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by
27、any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional p
28、ublication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by ind
29、ependent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for an
30、y personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normati
31、ve references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsi
32、ble for identifying any or all such patent rights. International Standard IEC 61300-3-46 has been prepared by subcommittee SC86B: Fibre optic interconnecting devices and passive components, of IEC technical committee TC86: Fibre optics. The text of this standard is based on the following documents:
33、CDV Report on voting 86B/3076/CDV 86B/3165/RVC Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table.

41、 10,0 % 100,0 +/- 5,0 g 3.3 Apparatus The apparatus shall include the following elements: Traceable, calibrated gauge pins of tungsten carbide steel, 0,698 95 mm to 0,700 05 mm in 100 nm increments; Pin vice with rod and platform to hold calibrated mass elements, the mass of which is sufficient to m
42、ake the entire assembly 100,0 g total. Fixturing should ensure that the assembly is free to hang vertically during testing. Both pins and test parts should be as clean as possible to ensure an accurate measurement. 4 Procedure Parts should be preconditioned using the conditions in 3.2 for a minimum
43、of 24 hours. Once conditioned, a calibrated gauge pin is pushed into the ferrule until it clears the ferrule end as shown in Figure 1. Start with a pin that should fit freely in the part under test. Rear entry is recommended where possible to reduce the risk of ferrule end face damage. (For fully as
44、sembled product, front entry may be used as an alternative to disassembly as shown in Figure 3.) After the pin engages the full bore ID length, the pin vice is secured to the calibrated gauge pin/ferrule vice assembly as shown in Figure 2. The mass is gradually released, pulling the pin through the
45、bore. This procedure is repeated using increasingly larger pins until the 100,0 g 5,0 g mass cannot freely pull the pin out of the bore. Once this state is reached, the previous pins diameter is recorded as the effective diameter of the guide pin bore. Repeat the above procedure for the opposite hol
