Referenced standards¶
Standards listed in GB 38031-2025, Section 2 (Normative References) and the References section at the end of the document.
Normative references (Section 2)¶
These standards are referenced normatively — their requirements form an essential part of GB 38031-2025. Where a date is given, only that version applies; otherwise, the latest version (including amendments) applies.
| Standard | Title | Where used in GB 38031-2025 |
|---|---|---|
| GB/T 2423.4 | Electrical and Electronic Products Environmental Testing — Part 2: Test Methods — Test Db: Damp Heat (12h+12h Cycle) | Damp heat cycling (8.2.5) |
| GB/T 2423.17—2024 | Environmental Testing — Part 2: Test Methods — Test Ka: Salt Spray | Salt fog (8.2.9) |
| GB/T 2423.43 | Vibration, Shock, and Similar Dynamic Tests — Mounting of Specimens | Vibration (8.2.1), Simulated collision (8.2.3) |
| GB/T 2423.56 | Test Fh: Wideband Random Vibration and Guidelines | Vibration (8.2.1) |
| GB/T 4208—2017 | Enclosure Protection Levels (IP Code) | Immersion (8.2.6) Method 2 (IPX7) |
| GB/T 19596 | Terminology for Electric Vehicles | Section 3 (general EV terminology beyond the terms defined in §3) |
| GB/T 28046.4—2011 | Road Vehicles — Environmental Conditions and Testing for Electrical and Electronic Equipment — Part 4: Climatic Loads | Salt fog (8.2.9) |
Informative references (References section, end of document)¶
These are referenced informatively — they're cited as examples of acceptable methods (e.g., for risk-reduction analysis under Appendix C.3.2) but are not strict requirements.
| Standard | Title | Where used |
|---|---|---|
| GB/T 4780—2020 | Automotive Body Terminology | Definition of "body frame" (3.20) |
| GB/T 20438 (all parts) | Functional Safety of Electrical/Electronic/Programmable Electronic Safety-Related Systems | TP risk reduction analysis (C.3.2) |
| GB/T 34590 (all parts) | Road Vehicles — Functional Safety | TP risk reduction analysis (C.3.2) |
| ISO 26262 (all parts) | Road Vehicles — Functional Safety | TP risk reduction analysis (C.3.2) |
| IEC 61508 (all parts) | Functional Safety of Electrical/Electronic/Programmable Electronic Safety-Related Systems | TP risk reduction analysis (C.3.2) |
Engineering note (non-normative): The functional-safety standards (GB/T 20438, GB/T 34590, ISO 26262, IEC 61508) are listed as examples for the TP risk-reduction analysis. The standard says "or similar methods" — manufacturers may use any reputable functional-safety methodology. In practice, OEMs supplying both Chinese and European markets typically use ISO 26262 to satisfy both jurisdictions.
Engineering note (non-normative): When a standard is referenced without a date (e.g., GB/T 2423.43), the latest version including all amendments applies — so the test lab must use the current edition at the time of testing, not the edition current when GB 38031-2025 was published.
