IEC 61300-2-46 is to describe a test to determine the suitability of a fibre optic device to withstand the environmental condition of high humidity and change of temperature which can occur in actual use, storage and/or transport. The test is primarily intended to determine the suitability of fibre optic components under conditions of high humidity - combined with cyclic temperature changes and, in general, producing condensation on the surface of the device under test (DUT). Absorption of moisture can result in swelling that would destroy functional utility, cause loss of physical strength, and cause changes in other important mechanical properties. Degradation of optical properties can also occur. Although not necessarily intended as a simulated tropical test, this test can, nevertheless, be useful in determining moisture absorption of insulating or covering materials. - THIS REDLINE VERSION PROVIDES YOUR WITH A QUICK AND EASY WAY TO COMPARE ALL THE CHANGES BETWEEN THIS STANDARD AND ITS PREVIOUS EDITION. A VERTICAL BAR APPEARS IN THE MARGIN WHEREVER A CHANGE HAS BEEN MADE. ADDITIONS ARE IN GREEN TEXT, DELETIONS ARE IN STRIKETHROUGH RED TEXT.
