5、andards and Publications are adopted by TIA/= in accordance with the American National Standarcis Institute (ANSI) patent policy. By such action, “A does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the Standard or Publidon. This Standa

6、rd does not purport to address all safety problems associated with its use or all applicable regulatory requirements. It is the responsibility of the user of this Standard to establish appropriate .a-acy of better than or equal to 0.1 of the pass/fail criteria (traceable to NIST) for calibration. 3.

7、3 Measurement apparatus (method 2). Use a measurement apparatus with an optical microscope with magnification appropriate for the test, an apparatus for holding and rotating the specimen around an axis that is capable of changing the position of the specimen with regards to the rotation axis, and a

8、roundness measuring instrument with calibration traceable to NIST. 3.4 Measurement apparatus (method 3). Use a measurement apparatus with a V-groove alignment fixture, a height measurement instrument with a carbide stylus probe, and a means of rotating the specimen while holding it against the align

9、ment fixture. The resolution of the height measurement instrument shall be greater than one-tenth of the acceptance criterion specified in the detail specification. 4 Sampling and specimens - Unless otherwise specified in the Detail Specification, use an optical fiber connector ferrule for the test

10、specimen. The specimen may be part of an optical fiber connector at the time of measurement. Keep the specimen free from dirt or dust with a front surface polished sufficiently to allow delineation of the boundaries of the hole. NOTE: The specimen should be cleaned at some time before performing thi

11、s test procedure. 2 Copyright Electronic Industries Alliance Provided by IHS under license with EIANot for ResaleNo reproduction or networking permitted without license from IHS-,-,-TINEIA-455-1 35 5 Procedure NOTE: Make sure that the specimen and the test apparatus are clean before making any measu

12、rements. Parts can be cleaned using an alcohol wipe and dried using compressed air. 5.1 Method 1 5.1.1 Place the linear standard under the microscope. Focus the microscope on the linear standard. Adjust the lines on the reticle (or TV monitor) to the spacing specified in the detail specification. 5.

13、1.2 Insert the specimen into the V-groove with the front surface toward the microscope and the specimen outer diameter against both sides of the V-groove. Move the holder-rotator into position to hold the specimen in the V-groove. 5.1.3 Focus the microscope on the front surface of the specimen and b

14、ring the hole edge to the center of the viewing area. Rotate the part and observe the position where the hole edge opposite the V-groove apex is closest to the V-groove apex. Position the first line of the reticle at this edge location (see figure 2). Completely rotate the specimen and observe if th

15、e hole edge passes the second line on the reticle. Small surface imperfections on the hole edge may be ignored provided that they do not extend into the hole or they do not subtend more than a IOo angle. 5.2 Method 2 5.2.1 Insert the specimen into the ferrule holder and position the microscope so as

16、 to view the specimen end surface. Adjust the ferrule holder until the axis of rotation of _- the specimen is at the center of the specimen hole. 5.2.2 Place the pick-up of the roundness measuring instrument against the specimen outer surface so as to measure the displacement of the outer diameter o

17、f the specimen as the specimen is rotated. 5.2.3 Completely rotate the specimen and record the maximum reading from the roundness gauge as C, and the minimum reading as C,. 5.3 Method 3 5.3.1 Insert the specimen into the alignment fixture with the ferrule front surface towards the height measuring i

18、nstrument and the specimen outer diameter against both sides of the V-groove. Move the specimen rotator into position to hold the specimen in the V-groove. 3 Copyright Electronic Industries Alliance Provided by IHS under license with EIANot for ResaleNo reproduction or networking permitted without l

The stylus should b

20、e held at a slight angle relative to the axis of the femle so that the measurement is from the chamfer at the tip of the stylus. Place the stylus against the inside wall of the ferrule closest to the apex of the alignment fixture so as to measure the displacement of the inner diameter of the specime
