Foreword

GB/T 31465 "Road vehicles - Fuse" consists of seven parts.

--- Part 1. Definitions and general test requirements;

--- Part 2. User's Guide;

--- Part 3. blade fuse;

--- Part 4. fuse socket and bolt;

--- Part 5. board fuse;

--- Part 6. Bolt-voltage fuse;

--- Part 7. Short pin fuses.

This section drafted in accordance with GB/T 1.1-2009 given rules.

This section uses redrafted Law Amendment uses ISO 8820-5:2007 "Road vehicles - Fuse - Part 5. SF30 and SF51 Chip-type fuses and test fixtures "were developed.

This part of ISO 8820-5:2007 technical differences and the reasons are as follows.

--- Of Chapter 2, this section has been adjusted technical differences, or both will be transformed into our standard international standards change For our standards, see Chapter 2.

--- In order to facilitate the use of standards for the text refer to the GB/T 31465.1 terms of numbers are added.

--- 5.1.1 of the "test sequence shall be specified in Table 2" Move to 5.1.2, which is more logical and write standard requirements.

--- 6.1.1 adds SF30 fuse size, see Figure 2.

--- 6.2.1 adds SF51 fuse size, see Figure 3.

--- On international standards and tolerance bolts, nuts and washers references to the corresponding national standards. 7.2 in the original Decentralized and centralized depicted in FIG specified in the table.

--- Deleted text unused ISO 8820-2 reference files.

--- Note 5.8.1 will move to Table 2, the preparation of standard requirements.

--- Table 1, Table 3 and Table 4 supplements SF51 type parameter 40 ~ 70A, in order to meet the current needs of the market. And added note release. Table 5 "80A ~ 250A" adjusted "40A ~ 250A".

--- Add notes in 5.1.2. If the agreement between temperature rise test may be done with reference to the rest of the series of standard provisions. Maintainer line Column harmonization of standards, increased operability.

--- 6.1.2 named in accordance with industry practice example increased rated voltage.

Editorial changes as follows. "." --- With the decimal point as the decimal comma instead of the original "";

--- Delete foreword international standards;

--- According to GB/T 1.1 seek to amend the scope of the definition or description and other text format.
