Foreword
GB/T 31465 Road Vehicle – Fuse-Links includes the following 7 parts.
--- Part 1. Definition and General Test Requirements;
--- Part 2. User Guide;
--- Part 3. Fuse-Link with Blade Type;
--- Part 4. Fuse-Links with Female Contacts and Bolt-in Contacts;
--- Part 5. Strip Fuse-Links;
--- Part 6. Fuse-Links with Bolt-in Contact with High Voltage;
--- Part 7. Fuse-Links with Shortened Tabs.
This Part belongs to Part 6 of GB/T 31465.
This Part was drafted as per the rules specified in GB/T 1.1-2009.
This Part adopts the re-drafting method to modify and use ISO 8820-8.2012 Road
Vehicles – Fuse-Links – Part 8. Fuse-Links with Bolt-in Contacts (Type H and J) with
Rated Voltage of 450V.
The technical differences and causes between this Part and ISO 8820-8.2012 are as
follows.
--- Three H1 of Type-H in Table 9 is the obvious error of the original text, which shall
be H1, H2, and H3.
--- For the Clause 2, this Part adjusts the technical differences; modify the
international standards that have converted or is about to convert into our
national standards into the national standards; delete the document ISO 8820-2
that has not been quoted in the text. The specific situation can refer to Clause 2
“Normative References”.
--- Transfer the original text’s 5.1 “test sequence shall be subject to the provisions
of Table 2” to the 5.1.1; which conforms to the logic and standard preparation
requirements more.
--- Delete original text’s 5.1.2 “only use the wire with wall-thickness specified in ISO
6722”, due to the actual situation, the thin-walled wire can also be used.
--- For the sake of standard use, the text quoted from GB/T 31465.1 are added the
clause number.
--- Referring to JASO D622-2011, change 450V in the Clause 1 into 60V~450V, so
that the description of applicable scope is more accurate.
--- The Table 2, Table 3 and Table 6 are increased two specification types of 80A
and 250A as per JASO D622-2011 to facilitate the user selection. Thereof, 250A
in Table 2 corresponding test wire specification JASO D622 is 100mm2, which is
inconsistent with our national wire specification; the closest 100mm2 of 95mm2
in GB/T 25085 is determined to change into 95mm2, which can totally meet the
requirements of test.
--- Delete the original text’s 5.6 without specific requirements, the following clause
number shall be modified correspondingly.
--- Transfer the NOTE in 5.7.1 (original text’s 5.8.1) into the Table 1, so that facilitate
the understanding and textual description.
--- For 5.9 (original text’s 5.10) temperature impact test, the original text appears
obvious errors (drawing number and test time); this Part directly quotes 5.4.2.3
in Clause 1, so that avoid repeated provisions and inconsistency.
--- The original text’s Appendix A is not mentioned in this text; add NOTE to Clause
1 of this Part, so that the appendix echoes with the text.
This Part shall be under the jurisdiction of National Technical Committee for
Standardization of Automotive (SAC/TC 114).
