This document provides specific safety requirements for the design and use of personal light electric vehicles totally or partially electrically powered from self-contained power sources for domestic and commercial use. This document applies to personal light electric vehicles with maximum speed up to 25 km/h. This document applies to personal light electric vehicles without self-balancing system totally or partially electrically powered from self-contained power sources having battery voltages up to 100 VDC, with or without an integrated battery charger with up to a 240 VAC input. This document specifies safety requirements, test methods, marking and information relating to personal light electric vehicles to reduce the risk of injuries to both third parties and the user during intended use, i.e. when used as intended and under conditions of misuse that are reasonably foreseeable by the manufacturer. This document provides specific prescription to assess the safety of personal light electric vehicles intended for leisure activities. This document provides a recommended method to assess the performance of personal light electric vehicles totally or partially electrically on: total run time (battery run time). This document does not apply to: — vehicles that are considered as toys; — vehicles with self-balancing system; — vehicles with seating position; — vehicles without handle bar; — vehicles intended for competition; — electrically powered assisted cycles (EPAC); — vehicles and/or devices intend for use for medical care; — electric vehicles having a maximum design speed above 25 km/h; — vehicles having a rated voltage of more than 100 VDC or 240 VAC; — vehicles without an on-board driving operator; — vehicles intended for the transport of goods and other services. NOTE 1 See D.2. NOTE 2 The local regulation could limit the use of the vehicle to a speed lower than 25 km/h.

A multipart set of documents is envisioned as part of the 19885 series, Gaseous hydrogen -- Fuelling protocols for hydrogen-fuelled vehicles. The 19885 documents will address the general design and development process for the definition and verification of fuelling protocols and the implementation of the protocols for dispensing fuel to hydrogen vehicles rated up to 70 MPa nominal working pressure (NWP). This NP proposes the following project: 19885-2: Gaseous hydrogen – Fuelling protocols for hydrogen fuelled vehicles – Part 2: Definition of communications between the vehicle and dispenser control systems Focus is on the communication system needed to implement the fueling protocols defined in ISO 19885 series to fuel hydrogen vehicles. Approach: • To be written in the context anticipated use as the document proceeds industry application, • Coordinate with 19885-3 to establish the communications to utilize versatile high-flow hydrogen fuelling protocol(s) for 35 or 70 MPa NWP compressed gaseous hydrogen-powered heavy-duty road vehicles (10-200 kg hydrogen capacity). • Specific systems to be given as examples but applying the communication protocol will not be limited to a particular system. The definition of communications systems in ISO 19885-2 is intended to address the different communications UCDC levels referenced in hydrogen fuelling protocol(s) standards ISO 19885-1 and 19885-3.

This NP proposes the following project: 19885-3: High Flow Hydrogen Fuelling Protocols for Heavy Duty Road Vehicles Versatile high-flow hydrogen fuelling protocol(s) for 35 or 70 MPa NWP compressed gaseous hydrogen powered heavy-duty road vehicles (10-200kg hydrogen capacity). Use is intended for but not limited to heavy-duty road vehicles. The hydrogen fuelling protocol(s) in the standard are intended to address different communications UCDC levels in accordance with ISO 19885-1. However, the initial scope will focus on fuelling protocol(s) capable of utilizing UCDC levels 0 and 1 given the existing widespread market use. Approach: • Develop science based and empirically validated fueling protocols which are coordinated with the appropriate HF nozzle, receptacle and communications for HD vehicles • Adopt best practices for fueling taking into consideration regional experiences • Coordinate with established and other relevant standards groups such as SAE • Consider the results and findings of the European Commission funded project “Protocol for Heavy-Duty Hydrogen Refueling” (PRHYDE) • This document can be viewed as a stand-alone document to address a high flow fueling protocol or it could be viewed as part of a series of documents that address the general definition and verification of fueling protocols and communication protocols.
