Foreword

GB/T 31465 "Road vehicles - Fuse" includes seven sections.

--- 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 GB/T Part of 431,465.

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

This section uses redrafted modification method using ISO 8820-4:2010 "Road vehicles - Fuse - Part 4. Box-type fuse socket Breaker (A type) and bolt fuse (B type) and the test fixture "in the development.

This part of ISO 8820-4:2010 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.

--- The 5.1 "test sequence shall be specified in Table 2" Move to 5.2, in line with the requirements of the standard write.

--- Complement to A and B-type fuses fuses described in 5.1.

--- Original temperature requirements 5.11.2 industry agreed that the limit is too wide, part of the increased "or negotiated by both parties agreed to" increase Operability standards.

--- Table 3 to remove the Japanese and American specifications of wire cross-sectional area (AB), retaining only the national standard.

--- Reference to Part 3, the fusing time and current gradient two requests increased "after the fuse at rated voltage by fuses the current should not exceed 0.5mA ".

--- Original content and climate load 5.12 5.6 repeat, and the lack of specific requirements, belonging to the original error, delete this section 5.12, the same when the contents of the corresponding adjustment table 2, and 5.12 delete references involved in ISO 16750-4.

--- Original Chapter 7 bolts, washers and nuts not given requirements, supplemented this part with reference to Section 5, to increase the standard of Operability, and a corresponding increase in the reference standard. And other standards to be consistent, while increasing operability standards, increased "The figure does not specify dimensional tolerances GB T 1804 shall comply with the provisions of the tolerance level /", Chapter 2, the corresponding increase in references standard.

--- Original Type B1 and B2 type fuse terminal is not given thickness dimension in this section refer JASOD622.2011 in Figures 6, 7 and Table 10, the t size.

--- Original pictures have a lot of obvious errors, some belong mislabeled, and some real car assembly not on this part have been adjusted.

The lead position 4 in Fig. 8, 9 made a change, FIG. 9 dimensions 15 ± 0.1 to 15.

--- 6.4 Naming example, in accordance with industry practice increases the 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.

This part is proposed by the National Development and Reform Commission.

This part of the National Automotive Standardization Technical Committee (SAC/TC114) centralized.
