Industrial Edge AI Computing Physical No-RF & Non-DG Air-Freight Readiness Guide · Overseas Technical Standards & Export Readiness Reference Library

Physical No-RF BOM · Zero CR2032 (No UN3091) · -20°C to 60°C — Explains factory-level hardware configuration for fanless industrial edge AI computers (RK3588 / Jetson Orin carrier boards): leaving Wi-Fi/BT/cellular pads physically unpopulated (No-RF) and omitting CR2032 lithium metal coin cells in favor of supercapacitor RTC and NTP/PTP synchronization (Non-DG).

1. Applicable International Standards & Regulatory Matrix

Standard / Directive	Jurisdiction & Scope	Technical Requirement & Acceptance Limit
IATA DGR (Non-DG / Zero UN3091)	International Air Transport Regulations	Omitting the CR2032 lithium metal CMOS battery at assembly ensures the unit contains zero lithium metal or lithium-ion cells, qualifying as general non-dangerous cargo (Non-DG) without UN3091 hazmat surcharges.
EN 55032 / EN 55035 (CE-EMC)	European Union Wired ICT EMC	With M.2 wireless slots empty and onboard RF transceivers/antennas physically unpopulated at SMT, the unit operates strictly as wired industrial ICT equipment under the EMC Directive.
FCC 47 CFR Part 15 Subpart B & VCCI	US & Japan Unintentional Radiator Rules	Tested and declared as a Class A unintentional digital radiator without intentional RF transmitters.
IEC 60068-2-1 / 2-2 / 2-64	Industrial Wide-Temp & Vibration Reliability	Validates fanless passive thermal dissipation across -20°C to +60°C ambient operating ranges and industrial random vibration profiles.
IEEE 1588 PTP / RFC 5905 NTPv4	Battery-Free Time Synchronization	Pre-configured OS boot synchronization via chrony/NTPv4 or hardware PTP paired with a board-level supercapacitor for short-duration RTC retention.

2. Engineering Verification Parameters & Lab Test Protocols

Physical No-RF BOM & PCB Verification: Unpopulated onboard RF IC footprints, empty M.2 Key-E/Key-B sockets, and plugged antenna bulkhead ports verified via high-resolution PCB inspection photography.
Supercapacitor RTC & Network Time Convergence: Zero CR2032 coin cell installed; cold-boot NTP/PTP time synchronization convergence ≤ 2.0 seconds upon Ethernet link-up.
Industrial Port Surge & ESD Immunity: Dual 2.5GbE/PoE+ vision ports and isolated RS485/CAN interfaces verified to IEC 61000-4-2 (±6kV contact / ±8kV air ESD) and IEC 61000-4-5 surge immunity.

3. Factory Shipment Technical Documentation Checklist

Technical Document Deliverable	Verification Method & Sign-off Protocol
Factory Physical Non-RF Hardware Declaration	Signed engineering declaration specifying PCB revision, unpopulated RF BOM designators, and internal macro photographs (`radio approval not applicable — no radio fitted`).
Non-Dangerous Goods (Non-DG) Air-Transport Statement	Manufacturer and accredited cargo-testing confirmation that no lithium metal (UN3091) or lithium-ion (UN3481) cells are present.
Wired Variant CE-EMC & FCC Part 15B Test Report	Accredited EMC test report covering the non-radio hardware configuration (`EMC_VARIANT_DECL`).
48-Hour Burn-In & BSP Pinout Sign-Off Log	Linux/Ubuntu kernel image checksum, carrier-board pinout mapping table, and 48-hour continuous NPU thermal log.

4. Cross-Border Specification Alignment & Supply-Chain Coordination

Coordinated across Shenzhen Guangming/Bao'an/Longhua (RK3588 and Jetson carrier boards), Hefei/Wuhu (inland edge computing modules), and Chengdu/Mianyang (RF-free industrial control boards) under strict Consolidated Screening List (CSL) supplier compliance.
