Foreword

GB/T 15972 "fiber test methods" consists of several parts, its expected international standard and the corresponding structure and replaced by national standards Quasi is. --- Part 10 - Part 19. Measurement methods and test procedures - General (corresponding to IEC 60793-1-10 to IEC 60793-1-19; Replacing GB/T 15972.1-1998); This section is drafted. Wuhan Research Institute of Posts and Telecommunications. The main drafters of this section. Chen poetry, Li Haiqing, Liuze Heng, Cheng Shuling. This section first revision, it GB/T 15972.5 × other parts together instead of GB/T 15972.5-1998. Optical fiber test methods - Part 50. Methods of measurement of environmental performance and Test procedure --- constant heat

1 Scope

This section GB/T 15972 specifies the assessment of fiber optic measurement and test procedures for heat performance in a given environment. This section applies to determine the class A1 and class B multimode fiber single-mode fiber in practical applications, storage and (or) that may occur during transportation Adapt performance under high temperature and high humidity conditions. Note. The test applicability to other types of optical fiber in the study.

3 test device

3.1 Test Chamber GB/T 2423.3-2006 Test Ca, the test device includes an environmental chamber. Chamber size should be able to accommodate Test sample and facilitate measurement when the conditions are adjusted, it is possible to maintain a predetermined temperature and humidity values \u200b\u200bwithin the specified tolerance, the available air circulation To maintain uniform conditions in the test chamber, while the chamber resettlement and related accessories should avoid condensation of water droplets onto the sample. 3.2 humidistat Softened or deionized water to adjust the desired humidity, there should be no rust or corrosion pollution affect the test sample devices. Water was added to the humidistat should be controlled in accordance with operating instructions. 3.3 Other devices We need to complete other devices (such as a device specified in the detail specification) test and measurement necessary.

4 Sample and Sample Preparation

Attenuation measurement repeatability, the fiber sample length to achieve the required fiber for A1 class should be at least 1000m, the class B fiber to be
