The certification framework typically operates on three levels:
1. Regional Market Access Directives: This is the mandatory "license to sell."
- European Union (EU): The CE mark is mandatory, primarily involving the Pressure Equipment Directive (PED 2014/68/EU) for the tank and assemblies, and the ATEX Directive (2014/34/EU) for equipment in potentially explosive atmospheres. The Measuring Instruments Directive (MID 2014/32/EU) may apply to the dispenser.
- Eurasian Economic Union (EAEU): The EAC (Eurasian Conformity) mark is required, with technical regulations like TR CU 032/2013 on pressure equipment safety.
- North America: While no single mark exists, equipment must comply with a matrix of standards from ASME (tanks), UL/CSA (electrical), and NFPA (fire safety), often requiring local Professional Engineer (P.E.) stamps.
2. International Performance and Safety Standards: These are the "how-to-build" benchmarks that underpin directives.
- Containment & Structure: ISO 668 (container dimensions), ASME Boiler and Pressure Vessel Code, API 650 (welded tanks).
- Safety: ISO 28300 (Petroleum/chemical industry fuel storage), NFPA 30 (Flammable and Combustible Liquids Code), IEC 60079 series for explosive atmospheres.
- Measurement: OIML R 117 for fuel meters, ensuring trade-grade accuracy.
3. Operational and Environmental Certifications: These are often project-specific.
- Environmental: Certifications for Vapor Recovery Units (VRU) from bodies like the California Air Resources Board (CARB) or TÜV.
- Extreme Environment: Certifications like the "Arctic" notation mentioned earlier, proving functionality in severe cold.
Proactive Strategy: The key for project teams is to engage with suppliers early. Specify the target deployment regions at the procurement stage. Reputable suppliers will have a modular compliance strategy, designing core components to the highest common denominator (e.g., ATEX and ASME) and managing the specific certification logistics for the end destination. This foresight prevents costly retrofits, customs delays, and legal exposure, ensuring your mobile refueling point is not just operational, but fully legally compliant from day one.
