Introduction

This section is one of the four existing standards supporting ISO /IEC 11801 and other cabling standards. Figure 1 shows this part of the ISO /IEC 11801, other cabling international standards and cabling related standards. Figure 1 standard relationship diagram ISO /IEC 14763-3 specifies the inspection and testing procedures for optical fiber cabling as well. a) Conforming to the cabling standards for buildings such as ISO /IEC 11801, ISO /IEC 24764, ISO /IEC 24702 and ISO /IEC 15018 Required fiber optic cabling design; and b) Fiber optic cable installation according to ISO /IEC 14763-2 requirements and recommendations. Users in this section should be familiar with the relevant building group cabling standards and ISO /IEC 14763-2. Each installed quality plan should clearly define the acceptance test and sampling level it chooses. Quality plan requirements and recommendations in ISO /IEC 14763-2 stipulated. Note. JTC1/SC25, in cooperation with IEC /TC86, is currently studying a totalization model to estimate as expressed in the ISO /IEC 11801 reference implementation Overall uncertainty. Once this model has been validated, it can be incorporated into this section by way of an amendment to eliminate the current designation "ffs" (to be studied) Terms. Implementation and Operation of Information Technology Users' Building Cluster Cables Part 3. Fiber Optic Cable Testing
