21、SIC TEST AND MEASUREMENT PROCEDURES Part 3-1: Examinations and measurements Visual examination 1 Scope This part of IEC 61300 provides criteria for the visual and mechanical examination of fibre optic piece parts, connectors and passive components. The examination method may be used at any stage of
22、the qualification or quality conformance inspection process, as a stand-alone test, or as required by the relevant specification. Visual examination of the polished end-face is defined in IEC/PAS 61300-3-35 and does not form part of this document. 1 General description This standard describes two ex
23、amination techniques. b) Method 1: Visual examination of the specimen to ensure that it is of the proper configuration, that the workmanship is satisfactory and that the marking is correct. b) Method 2: Mechanical examination of the specimen to ensure that the dimensions and mass conform to the rele
24、vant specification. NOTE Ensure the sample is un-energised, i.e. it is not transmitting optical power, prior to undertaking a visual examination. 1 Apparatus The apparatus shall consist of the following elements. 1.1 Visual examination Where specified in the relevant specification, visual examinatio
25、n shall be undertaken using an optical magnifier and an illuminator. 1.1.1 Optical magnifier Use an achromatic lens with a magnification power value between 2 and 5. An anti-reflection lens coating is recommended, but not mandatory. 1.1.1 Illuminators Integral or supplementary magnifier illumination
26、 may be utilized. Sources shall produce neutral “white light”, temperature-corrected to approximately 3 000 K. Positive ventilation or other illuminator provisions shall prevent deleterious heat transfer to test specimens. EN 61300-3-1:2005 5 1.1.1 Special equipment Colour samples, etc., as applicab
27、le, shall be required to verify fit, performance, colour, finish or other specified parameters according to the relevant specification. 1.1 Mechanical examination 1.1.1 Dimensional measurement instruments The accuracy and precision of dimensional measurement instruments, such as micrometers, measure
28、 scope, or profile projectors shall be sufficient to satisfy the specification requirements. 1.1.1 Mass measurement instruments The accuracy and precision of mass measurement instruments, such as electric balances, shall be of sufficient to satisfy the specification requirements. 1.1.1 Special equip
29、ment In some cases, special equipment such as gauges, etc., may be required to verify performance or other specified parameters according to the relevant specification. 1 Procedure 1.1 Method 1a Unaided visual examination The procedure for method 1a is the following. a) Prior to testing, clean the s
30、pecimen according to the manufactures instructions. a) Gently put the specimen onto the examination table or into the appropriate fixture, or gently hold the specimen by the fingers. a) Examine the specimen visually to verify that it meets the specified requirements. Examples where unaided visual ex
31、amination might be used include: identification of product (marking); damage (scratch, pit, crack); contamination, stain; missing parts. 1.1 Method 1b Aided visual examination The procedure for method 1b is the following. a) Prior to testing, clean the specimen according to the manufacturers instruc
32、tions. a) Gently put the specimen onto the examination table or into the appropriate fixture of the visual examination apparatus. a) Adjust the lenses to achieve the required magnification as stated in the relevant specification. a) Examine the specimen visually using the specified optical magnifica
33、tion to verify that it meets the specified requirements. EN 61300-3-1:2005 6 Examples where aided visual examination might be used include: fibre alignment; contamination ; damage (scratch, pit, crack). 1.1 Method 2 Mechanical examination The procedure for method 2 is the following. q) Prior to test
34、ing, clean the specimen according to the manufacturers instructions. q) Gently put the specimen onto the examination table or into the fixture of the mechanical measurement apparatus. q) Measure the specimen using the appropriate measuring instrument to verify that it meets the specified requirement
35、s. 1 Details to be specified The following details, as applicable, shall be given in the relevant specification: type of testing; component type, configuration and marking; size dimensions and mass to be measured; size measurement methods; mass measurement method; acceptance/failure criteria; deviat
36、ions from examination procedure.
