CSA Group Seeks Experts for Projects to Improve NGV Standards

 

CSA Group is seeking experts from the natural gas vehicle industry to serve on Technical Subcommittees to further improve the codes and standards that support the NGV industry. Based on CSA Group’s engagement with NGV industry stakeholders, CSA Group looks to address an immediate need to develop and revise codes and standards to support the deployment of natural gas vehicles. As a result, CSA Group is launching a variety of projects to develop new standards or revise existing standards for the natural gas vehicle industry.

CSA Group is seeking additional experts to serve on the Technical Subcommittees for the projects in the table below:

Standard

Designation

TitleNew or RevisedScope
B401

 

Maintenance FacilitiesNewDevelop a new Canadian Code for NGV maintenance facilities and indoor refueling operations. The new Code will amalgamate existing requirements and the specific requirements for NGV (CNG and LNG) storage, parking, repair, maintenance, fueling, and operation in Canadian facilities.

 

It is anticipated that this new Code will be adopted by the Provinces & Territories allowing NGV facility approval by the local Authority Having Jurisdiction.

LNG 3.1

 

Fuel System Components for Liquefied Natural Gas Powered VehiclesNewThe projected binational standards will be adoptions of the ISO 12614-x, 18-part series for Liquefied natural gas (LNG) fuel system components for road vehicles. The LNG components covered include: fill check valve, heat exchanger – vaporizer, fuel shut-off valve, fill fitting,  excess flow valve, automatic fuel shut-off valve, vapour shut-off valve, tank pressure gauge, tank pressure regulator, pressure regulator, primary relief valve (PRV), vent connector, secondary relief valve (PRV), gas temperature sensor, fuel content gauge, ECU electronic control unit of engine.

 

LNG 4.1

 

Liquefied Natural Gas Vehicle Dispensing SystemsNewThis new binational standard will cover (a) mechanical and electrical features of newly manufactured systems that dispense liquefied natural gas (LNG) for vehicles where such a system is intended primarily to dispense the fuel directly into the fuel storage container of the vehicle; (b) LNG dispensers contained in a single housing; and (c) LNG dispensers contained in multiple housings for metering and registering devices, remote electronics, remote overfill protection, hoses and nozzles.
SPE 2.1

(formerly EXP 2.1)

 

Defueling, Decommissioning, and Disposal of

Natural Gas Vehicle Fuel Containers (CNG and LNG)

RevisedThis updated binational document will provide a best practice for the Defueling, Decommissioning, and Disposal of Liquefied Natural Gas Vehicle Fuel Containers. This publication will enhance the first edition of EXP 2.1 which encompasses the defueling, decommissioning, and disposal of compressed natural gas vehicle fuel containers.

 

NGV 2

 

Compressed Natural Gas Vehicle Fuel ContainersRevisedThis standard addresses fuel containers intended for onboard storage of compressed natural gas (CNG) for vehicle operation.  The containers covered by this standard are permanently attached to the vehicle and are no more than 1000 liters water capacity.  Updates to the document will include coverage addressing conformable container designs and adsorbed natural gas (ANG) systems.

 

NGV 4.1/CSA 12.5

 

Natural Gas Vehicle Dispensing SystemsRevisedThe revision to this binational standard addresses the features of newly manufactured systems that dispense compressed natural gas for vehicles directly into a fuel storage container on the vehicle.  Updates to the document will be to incorporate additional content regarding temperature compensation for newly designed systems.
NGV 6.1

 

Compressed Natural Gas Fuel Storage and Delivery Systems for Road VehiclesRevisedThis binational standard applies to the design, installation, inspection, repair, and maintenance of the fuel storage and delivery system installed on road vehicles for use with compressed natural gas (CNG). This includes fuel systems on self-propelled vehicles for the provision of motive power.

 

This standard does not apply to:

a) stationary engines;

b) mobile equipment using natural gas as a fuel for other than propulsion;

c) electronic components or controls strategy of a fuel management system;

Updates to the standard will be to add fuel system tests.

Expectations of technical subcommittee members include active participation and a willingness to work on a CSA Group Committee electronically and in-person; attendance at teleconference meetings over approximately 12 to 18 months; ability to work in a multi-stakeholder environment, following the principles of consensus; strong interest, knowledge and willingness to research subject matter.
