ISO has sent out for ballot the 2nd Draft International Standard ISO/DIS 17519.2, Gas cylinders – Refillable permanently mounted composite tubes for transportation. The draft document has been prepared by ISO TC58 SC3. TC 58 focuses on the Standardization of gas cylinders, their fittings and characteristics relating to their manufacture and use, and SC3 looks specifically at cylinder design.
NGV Global, in its role as a leading international advocate for the natural gas for transportation industry, is recognised as a liaison organization by ISO and is an active participant in the work of ISO TC58 SC3. As a liaison organization NGV Global is committed to informing and seeking input from its members on any new ISO projects once they are approved by the ISO member bodies.
ISO/DIS 17519.2 has now been made available to NGV Global members for comment. At this stage, both technical and editorial comments are allowed. Responses are then collated by NGV Global’s technical team for submission.
Explanation of ISO Procedure (prepared by ISO)
The draft International Standard (DIS) is submitted to ISO/CS, which then circulates it to all ISO member bodies for voting and comment within a period of three months. During this time, ISO members make the DIS text available to the widest possible range of national stakeholders for comment – these comments form the basis of the national vote on the DIS. All full ISO member bodies are eligible to vote and P-members of the committee that developed the draft are obliged to vote. The text is approved if a two-thirds majority of the P-members of the TC/SC is in favour and not more than one-quarter of the total number of votes cast are negative (therefore including comments and votes from countries not having participated in the development of the standard). If the approval criteria are not met, the text is returned to the originating TC/SC for further study and revision.
Following approval of the DIS, the document then enters a final iteration phase, known as FDIS, whereby it is distributed for approval in a YES / NO ballot, the success of which leads to publication.
