Input and comment invited
The International Association for Natural Gas Vehicles (IANGV) has
awarded a contract to Australian based Dr Hien Ly to perform an
analysis of the gaps in the international NGV standards. The immediate
purpose of this analysis is to provide input to the Roundtable on
Harmonization of Standards to be held in Geneva on 10 January 2007.
This will enable the experts from various countries and with various
fields of interest to understand the need for harmonization.
The objective of the study is to identify the relevant international
standards and regulations pertaining to NGVs, to compare them and
identify key differences and to identify areas where there are
currently no published international standards or regulations. The
final report will contain a commentary on the results of the
investigation to assist other parties and experts to decide on what is
an appropriate course of action.
Currently harmonization work is in progress to address the differences
between ECE R110 and ISO 15500 (CNG vehicle gas system components),
thus the project will not go over this issue.
The areas covered by the study include vehicles, refuelling stations,
cylinder refuelling, and gas quality including natural gas, compressed
natural gas (CNG), liquefied natural gas (LNG) and biomethane. The
international standards and regulatory bodies include the International
Standardization Organization (ISO), the United Nations Economic
Commission for Europe (UN ECE) and the International Organization for
Legal Metrology (OIML).
The study will also identify areas where there are no international
standards, and existing international standards and regulations that
need revisions or amendments, in light of new industry and market
requirements. It should be noted that as part of the ongoing
maintenance process, ISO is currently considering the revision of
several of its CNG standards; other ISO standards will fall due in due
Dr Ly has worked in the whole range of technical and commercial areas
of NGV for over 25 years in several countries. He is also a long time
IANGV Technical Committee member, and has been on the committees of
several national and international NGV standards, some of which as
IANGV’s representative. He is currently chairman of Standards Australia
Committee AG 009 (CNG refuelling stations). Dr Ly will work in
consultation with the IANGV Technical Committee.
The work is expected to be completed by 30 November 2006. Enquiries,
comments and suggestions should be directed to Dr Ly at
