Detailed Standards Coverage

prEN ISO 27281 - Safety Requirements for Vehicle Washing Systems

Safety Requirements - Vehicle Washing Systems (ISO/DIS 27281:2025)

Scope: This standard sets comprehensive safety requirements for the design, equipment, and testing of vehicle washing systems, including those with and without brushes for indoor and outdoor operation. It applies to roll-over and tunnel-type washing systems and manually movable vehicle wash facilities—but excludes hand-guided high-pressure cleaners, water recycling systems, and certain powered cleaning machines.

Key requirements address hazards such as shearing, crushing, tripping, entanglement, electrical risks, and environmental hazards (including control of Legionella in stationary systems). The standard covers safety for operators, maintenance staff, people nearby, and vehicle occupants. Vehicle protection requirements guard against unintentional damage during washing operations.

Organizations involved in manufacture, installation, operation, and maintenance of vehicle washing systems, especially in commercial settings, must comply with these detailed hazard analyses and safety measures. Regular maintenance and proper staff training are essential for risk mitigation as per the standard’s recommendations.

Key highlights:

• Comprehensive hazard listing and required safety measures for system design and operation
• Specific guidance on protection against biological hazards (e.g., Legionella control)
• Clauses specifying requirements for electrical, mechanical, and control system safety

IEC 63584-210:2026 - Open Charge Point Protocol 2.1

Open Charge Point Protocol 2.1

Supporting the accelerating adoption of electric vehicles (EVs), this IEC standard specifies the latest communication protocol between charging stations and charging station management systems (CSMS). OCPP 2.1 introduces expanded support for bidirectional energy flows (V2X), Distributed Energy Resource (DER) control, and advanced authentications, incorporating lessons from recent deployments.

Key requirements are defined for all types of charging techniques, supporting seamless, secure communication essential for high-volume, smart grid-integrated EV charging. With updates such as new certification test profiles, enhanced error handling, and support for ISO 15118-20, the protocol simplifies integration for charging infrastructure operators and manufacturers.

Target users include EV charging station manufacturers, network operators, fleet managers, and infrastructure planners. For both public and fleet charging networks, implementing OCPP 2.1 ensures system compatibility, scalability, and future-proofed interoperability.

Key highlights:

• Introduction of certification profiles (for industry-aligned testing and conformance)
• New features: DER control, V2X, ISO 15118-20 integration, advanced payment use cases
• Backwards compatibility with OCPP 2.0.1, consolidating errata

ISO 19453-6:2026 - Environmental Testing for Traction Battery Packs

Road Vehicles — Environmental Conditions and Testing for Electrical and Electronic Equipment for Drive System of Electric Propulsion Vehicles — Part 6: Traction Battery Packs and Systems

This standard defines strict environmental and endurance test procedures for lithium-ion battery packs and systems used in all electric, hybrid, and fuel cell passenger vehicles. It provides a comprehensive framework for reliability assessment by classifying battery packs, defining stress levels, and specifying mechanical, electrical, water, dust, and corrosion resistance tests.

The target audience includes battery manufacturers, vehicle OEMs, and automotive testing labs. Adhering to these requirements is crucial for supplier qualification, homologation, and ensuring battery longevity and passenger safety.

Notable new aspects include revised references aligning with the merged ISO 16750 series and more refined acceptance criteria for mechanical and environmental stress. The scope covers pre-conditioning, durability, thermal cycling, and tests simulating operational real-world conditions.

Key highlights:

• Detailed mechanical categories and classifications for battery packs
• Standardized procedures for thermal cycling, water and dust protection, and corrosion resistance
• Updated integration with ISO 16750 series for wide harmonization

IEC 63584-201:2026 - Open Charge Point Protocol 2.01

Open Charge Point Protocol 2.01

IEC 63584-201:2026 standardizes version 2.0.1 of the Open Charge Point Protocol for EV chargers, building on the significant adoption since OCPP 2.0.1’s initial release. This edition brings about significant technical clarifications and improvements to test system requirements, use cases, and sequence diagrams, further supporting interoperability among diverse charging systems.

Key qualifications include comprehensive device management, improved error and state reporting, enhanced cybersecurity, and smart charging features. The changes facilitate large-scale network management for CSOs and system integrators, supporting better reliability and customer experience.
