1 Scope

GB/T 15972.55-2009 is the Chinese national standard on specifications for optical fibre test methods - part 55: measurement methods and test procedures for environmental characteristics-hydrogen aging, in the field of telecommunications and audio-video engineering. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 30 September 2009 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 December 2009. Classification: ICS 33.180.10, CCS M33. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This section GB/T 15972 specifies the optical fiber in a given environment in the hydrogen-containing hydrogen aging test methods and test procedures. This part is suitable for assessing GB/T 15972.10-2008 specified in B

1.3 class extended wavelength band dispersion unshifted single-mode optical Hydrogen aging performance fiber can also be used to evaluate the B4 class hydrogen aging performance single-mode fiber.

3 Test device

3.1 Test Chamber Test device includes an environmental chamber. The chamber should be able to accommodate the size of the test sample, the sample can not be subject to direct radiant heat, It can maintain the required temperature in the specified tolerance within the available air circulation to maintain uniform conditions of the test chamber.

3.2 Fiber container Size of the container should be able to accommodate optical fiber test samples, it can maintain the desired hydrogen-containing environments. Containers should be placed in environmental test chamber, and the container Materials heat transfer performance to ensure fiber samples and environmental test chamber set temperature in the vessel to reach consensus.

3.3 Other devices Other devices necessary to complete the test and measurement, if fitted (H2 + He) (hydrogen and helium) or (H2 + N2) (hydrogen and nitrogen) mixed Combined gas bottles.

4 Sample and Sample Preparation

In order to achieve the desired attenuation measurement repeatability, single-mode fiber sample length should be at least 2000m. Exposed outside the chamber light Fiber should be as short as possible, if the exposed portion of the total length of more than 10% of the sample, are advised to record instructions. There should be no impact to the environment caused by the optical fiber under measurement harm in the process of preparing a sample of. Unless otherwise specified in the detail specification, It recommended that the loose fiber samples around, rewind and cable attenuation coefficient at the wavelength of 1310nm response had no effect, rewind Zhang Liyi not more than 0.3N. The sample is placed horizontally, in order to avoid the impact of any macro bending, circling diameter should be greater than 150mm.
