34、vironmental test methods 1 Scope This part of IEC 60794 applies to optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and to cables having a combination of both optical fibres and electrical conductors. The object of this standard is to define tes

35、t procedures to be used in establishing uniform requirements for the environmental performance. Throughout the standard the wording “optical cable” may also include optical fibre units, microduct fibre units, etc. See IEC 60794-1-2 for general requirements and definitions and reference guide to test

42、ature cycling in order to determine the stability behaviour of the attenuation of cables submitted to temperature changes. Changes in the attenuation of optical fibre cables which may occur with changing temperatures are generally the result of buckling or tensioning of the fibres resulting from dif

43、ferences between their thermal expansion coefficient and the coefficients of the cable strength and sheath members. Test conditions for temperature-dependent measurements shall simulate the worst conditions. This test can be used either for monitoring cable behaviour in the temperature range which m

44、ay occur during storage, transportation and usage or to check, in a selected temperature range (usually wider than that required for the above-mentioned case), the stability behaviour of the attenuation connected to a substantially microbend-free situation of the fibre within the cable structure. NO

45、TE 1 Method F12 is a specialized subset of this method, specifically addressing cables for use in patchcords. NOTE 2 The ageing test, F9, uses Method F1 as its pre- and post-test temperature cycle. Often these tests are done together. Sample 3.2The sample shall be a factory length or a sample of suf

46、ficient length as indicated in the detail specification but, nevertheless, of length appropriate to achieve the desired accuracy of attenuation measurements. In order to gain reproducible values, the cable sample shall be brought into the climatic chamber in a manner such that the deployment does no

47、t affect the measurement. Such methods could be a loose coil or on a reel with large diameter coils, cushioned reels with a soft layer or a zero tension facility device. The ability of the fibre(s) to accommodate differential expansion and contraction (e.g. by slipping within the cable) could be inf

48、luenced by the bending radius of the cable. Sample conditioning should, therefore, be realized as close as possible to normal usage conditions. The bend diameter of the cable sample shall not violate the minimum bend diameter of the cable, tube or other unit as specified by the detail specification.

49、 Potential problems are due to an actual difference between the expansion coefficients of the test sample and of the holder (e.g. reel, basket, plate) which can induce, during thermal cycles, a significant effect on the test result if “no effect“ conditions are not completely fulfilled. The intent is to simulate the installed condition, in which the cable is generally straight for the majority of its length. Para
