Foreword

GB/T 7424 "General specification for fiber optic cable" is divided into the following sections. --- Part 1. General; --- Part 2. Basic optical cable test methods. This section GB/T 7424 "General specification for fiber optic cable," Part 2. The partial modification of the use of IEC 60794-1-2.2003 "cable - Part 1-2. Basic optical cable performance test methods", the main difference as follows. --- Chapter 3, "General", the amount of the value according to GB/T 8170 provisions of rounding; monitoring and inspection methods and sampling, according to the domestic market now Conditions specified; --- The IEC in the "definition of 3.3" and 3.6 "graphic symbols and the term" merger section 3.3 "Terms and Definitions" and IEC Text set out in Chapter 29 of the optical fiber ribbon to move the definition of this section; "3.4 standard atmospheric conditions" in the title changed to "test environment article Members and pre-conditions, "added specific provisions are summarized in" GB/T 2421-1999 Environmental testing for electric and electronic products Standard Test atmospheric conditions General "provisions;. Part 1 --- IEC method E14 "composite trickle" should be the environmental performance test methods in this section to F6. IEC method E15 "Analysis Oil and evaporation "is material testing, is not included in this section; --- Method E1 and E3 in method, supplemented with some details and specific data; --- Method E4, the proposed drop height 1m; --- E7 method, the twist angle increases the angle according to the relevant specification; --- The method of E10, the cable if bent determination to "make the ring diameter is reduced to a minimum in the relevant specification" and then Observed; --- The method of E11, the method name plus E11A "wound" for the method E11B plus name "U-bend"; --- Method of F1, increasing the general provisions "shall be samples treated at 20 ℃ ± 5 ℃ 24h" of. This Part replaces 7424.2-2002 GB/T "total cable specification - Part 2. Test methods for basic cable." This section GB/T 7424.2-2002 main differences are as follows. --- 3.4 title from "standard atmospheric conditions" to "test environment condition and pretreatment conditions" and direct reference to GB/T 2421- Specific provisions 1999; --- Cancel "3.6 graphic symbols and terms", the following entry number cis Save; --- 3.8 to 3.7, an increase of specific content; --- Increase the Chapter 4, "cable test" in order to IEC 60794-1-2.2003 same. This chapter describes the methods in this section number Happening. After a number of chapters postponed; --- Method E7 torsional angle increases the recommended value "± 180 °"; --- Method E13 is divided into two methods E13A and E13B. E13A original content is basically the same, but the point of impact on the number removed Limiting the amount of. E13B for newly added method; --- Method E18 E18A and E18B divided into two methods, procedures by the two increased to four. Increased local bending and single A plurality of local bending program; --- Method E19 "Wind Vibration" to develop the details, it is equivalent to using IEC 60794-1-2.2003 Method E19; --- Increased and developed a method of E20 "looped performance," the details of which identical with IEC 60794-1-2.2003 square Method E20; --- F6 pretreatment method limits the "cable sample of the total mass of 0.5% or 0.5g" to the smaller of the two; --- Increased and developed a method of F10 "hydrostatic pressure" and its details, it is identical with IEC 60794-1-2.2003 square France F10; --- Increased and developed a method for H1 "short circuit current test" and its specific content, it is identical with IEC 60794-1-2.2003 in Methods H1; --- Increased and developed a method for H2 "along the cable overhead power lines lightning test" and its specific content, it is tantamount to the adoption IEC 60794-1-2.2003 method H2.
