24、ibes the procedure to measure the withdrawal force between the ferrule (gauge pin) of the plug connector and the resilient alignment sleeve of the adapter. The gauge pin should have the same shape (chamfer) like the normal ferrules described in the optical interface, see IEC 61755-3 series and IEC 6
25、1754 series. This measurement procedure is applicable to single-fibre cylindrical ferrule optical connectors. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

28、ector is the difference between the breakaway friction force and the spring force of the connector. To maintain contact, the breakaway friction force must remain below the spring force. The ferrule withdrawal force is the highest force (breakaway force) required to remove one of the ferrules from th
29、e sleeve of a fibre optic connector. The mechanics of friction result in significant variations in the measurement of breakaway friction force. The criteria to be applied to the results of these measurements must account for the spread that is inherent in the mechanism being measured (see Annex B).
30、BS EN 61300-3-33:2012 6 61300-3-33 IEC:2012(E) 4 Apparatus 4.1 General The specimen is a resilient sleeve of a connector set. The measurement is made with two gauge pins inserted so that they meet at the centre of the sleeve. Force is applied to the end of one of the gauge pins as shown in Figure 1.
31、 Sleeves Gauge pin assembly Stop b a F IEC 174/12 Key a, b Gauge pin F Withdrawal force Figure 1 Test unit with applied force on the gauge pin 4.2 Test unit A force is applied to the gauge pin with a force generator that applies a continuously increasing force and is equipped with a force gauge to r
32、ecord the peak force that occurs at breakaway (see Annex A). The test unit is a sleeve with two gauge pins inserted so as to touch at the centre of the sleeve. The interface between the two gauge pins shall be located within 10 % of the length of the sleeve from the centre of the sleeve itself. 4.3
33、Gauge pins The gauge pins may be solid pins or connector ferrules that meet the gauge pin requirements. The gauge pin assembly consists of the gauge pin and a fixture for the application of load. The gauge pin is generally produced to the maximum material size of the resilient feature. The gauge pin
34、 shall be defined in the relevant specification. The definition shall include dimensions, material, surface hardness, roughness for the area of the gauge in contact with the resilient member and cylindricity. The requirements for the gauge pin are as follows: a) diameters of the gauge pins shall be
35、as specified in the relevant specification; b) the diameter of the two gauge pins used in a given test shall be within 0,5 m of each other; c) the lengths of each gauge pin shall be sufficient to allow it to extend half-way into the sleeve and have enough left protruding out of the sleeve to allow f
36、or the attachment of a fixture or force generator; 61300-3-33 IEC:2012(E) 7 d) the end of the gauge pin that is inserted shall have a nominal 45 chamfer to a depth of 0,1mm (breaking the edge of the gauge pin). e) the following normative values shall be used where the parameters are not defined in t
37、he relevant specification: zirconia ceramics shall be the material used; surface finish (Ra) and roundness shall be within 0,2 m and 0,5 m, respectively. 4.4 Solvent Prior to testing, each resilient alignment sleeve and gauge pin shall be cleaned by wiping, using for example lint-free wipes and swab
38、s. The cleaning action shall consist of thorough rubbing or scrubbing. Moistening wipes should be avoided. If moistening is necessary, following cleaning, resilient alignment sleeve and gauge pins are preconditioned at 40 C for 0,5 h and then returned to room temperature for at least 0,5 h. As solve
39、nt it is recommended to use IPA (isopropyl alcohol), see also IEC/TR 62627-01. It is recommended to choose solvents and cleaning agents in the observance of safety rules. 5 Test set up Force is applied to the end of one of the gauge pins and to the edge of the sleeve as shown in Figure 1. The test f
40、ixture shall be such that only two forces are applied to the moving gauge pin: the force withdrawing the pin, and the frictional force between the gauge pin and the sleeve. The force on the pin should be applied along the axis of the sleeve, as shown in Figure 1. The linkage through which force is a
41、pplied to the gauge pin assemblies shall not apply a bending load. Either swivel joints or flexible members are recommended when a load is applied to the gauge pin assemblies. The sleeves shall be reversed for a second set of measurements. 6 Procedure 6.1 General The measurement is made using a forc
42、e generator. Force is applied to one gauge pin, in order to extract it while the other gauge pin remains in place. During the test the resilient sleeve shall be free to move in radial direction. 6.2 Testing Effort should be taken during the test to avoid any contamination of the sleeves or gauges. T
43、o compensate for the weight of the test fixture, the indicator on the force gauge shall be adjusted to zero. Force is to be applied at a continuous rate (see Annex A). The maximum force applied to the gauge pin shall be recorded during extraction of the first third part of the whole length of the ga
44、uge pin inserted into the sleeve. BS EN 61300-3-33:2012 8 61300-3-33 IEC:2012(E) Unless otherwise specified, an equal number of measurements shall be made from each end of the sleeve. 7 Calculation or interpretation of results Unless otherwise specified, the set of data from the end of the sleeve wi
45、th the higher values of withdrawal force shall be used to characterize the sleeve. Sampling plans and the analysis of the results should be specified in the relevant specification. See Annex B for estimates of the repeatability and reproducibility of ferrule withdrawal force measurements. 8 Details
46、to be specified The relevant specification shall specify the following details: gauge characteristics (dimensions, roundness and cylindricity of gauge pins and rings, material hardness and surface roughness at the bearing surfaces); maximum allowable gauge retention force; pre-conditioning procedure
47、; recovery procedure; acceptance/failure criteria; number of times the test is performed on each component; configuration of the component under test; any deviations from measuring procedure; sampling plan; procedures for analysis of the data.

48、ormative) Loading velocity The rate at which force applied to the test unit shall be increased is limited by the response or the capture rate of the force gauge. With a mechanically driven instrument, the rate at which force increases is a function of both the velocity of the cross-head and the stif
49、fness of the linkage between the cross-head and the test unit. Loading rates of approximately 100 mm/min are generally considered acceptable for mech-anically driven instruments. The following equation may be used to evaluate peak error: E = cRKVwhere, K is the system stiffness forcedistance; V is the velocity of the crosshead distancetime; Rc is the capture rate of the force gauge eventstime. System stiffness is the ratio of the increase in force on th
