ANSI CSA HGV 4.3-2016 pdf download.Test methods for hydrogen fueling parameter evaluation
1.1 This Standard establishes the test method, criteria, and apparatus to evaluate a field installed hydrogen fueling station dispensing system (hereinafter referred to as a “dispenser”) as it relates to achieving the protocols specified in the SAE J2601 Standard, Fueling Protocols for Light Duty Gaseous Hydrogen Surface Vehicles, and the SAE J2799 Standard, Hydrogen Surface Vehicle to Station Communications Hardware and Software with light duty vehicle hydrogen storage systems less than 248.6 liters (10 kg H70). The testing evaluation applies to dispensers designed to fill vehicle storage systems following the prescribed protocols defined in SAE J2601 that targets rapid fills, while respecting temperature, pressure, and fuel density safety limits. Note: This Standard is a minimum requirement. Manufacturers may take additional safety precautions.
1.2 This Standard was developed for and is intended to be used with the specific version of SAE J2601 and SAE J2799 documents as referenced in Clause 2.
1.3 For fueling dispensers with the capability for communications with the vehicle, these test methods include the approach to confirm the requirements specified in SAE J2799 and SAE J2601.
1.4 It is recommended that newly manufactured hydrogen fueling dispensers be tested according to this Standard prior to initial operation of the dispenser for fueling vehicles. This Standard is also intended to provide test methods for validation of existing hydrogen fueling dispensers.
1.5 Unless otherwise specified, the requirements in this Standard apply to the verification of SAE J2601 compliant Hydrogen Fueling Stations (HFS).
1.6 In the case of conflict between this Standard and Federal, Provincial, State, or Local requirements, the governmental requirements take precedence.
Fueling event — the process of a dispenser filling a vehicle (or HDTA test tank). Each fueling event will start with a pressure pulse to establish vehicle start pressure and check for leaks at the hose and nozzle/receptacle connecting point, and includes a smooth pressure ramp rise and ends when the vehicle tank pressure equals the target pressure calculated by the dispenser system, or terminated by a halt command issued by the IrDA. Fueling protocol — a set of specification and requirements used to fuel an HSV within the process limits, as specified in SAE J2601. Fueling protocol, table based — a method of fueling an HSV using tables that specify APRR and target pressure based upon various parameters, as specified in SAE J2601. Fueling protocol tests — a set of tests used to determine if the dispenser applies the fueling protocol properly and does not exceed the process limits. Hydrogen gas — gas whose composition is to comply with SAE J2719, or ISO 14687. Hydrogen startup mass — the first 200 grams of H 2 that are delivered to the CHSS. The pulse may be delivered at a fixed pressure or a ramping pressure. Hydrogen surface vehicle — any light duty vehicle that stores and uses hydrogen as a fuel. An example of an HSV is a Fuel Cell Vehicle. Infrared data association — specifications for a complete set of protocols for wireless infrared communications used in SAE J2799.
Main fueling time — the period of gas flow between the start and the end of fueling. This does not include the startup and shutdown times, but can include other non-fueling times. Non-communication fueling — non-communications means that no valid data connection from vehicle to fueling station dispenser as per SAE J2799 exists, or that the received data has not been recognized as valid (or wished to be used) by the dispenser. Nozzle — device connected to a fuel dispensing system which connects to the Hydrogen Surface Vehicle (HSV) receptacle and permits transfer of fuel. Overall fueling time (T fueling ) — the total amount of time between when the user initiates the fueling at the dispenser until the nozzle can be removed. It includes the startup time, main fueling time, and shutdown time. Pre-installation testing — testing of a dispenser prior to installation at the station. Pressure — expressed as MPa. For this Standard, all pressures are assumed to be gauge pressure unless noted as absolute.ANSI CSA HGV 4.3-2016 pdf download
