Should you require an official interpretation relating to any Australian or ISO standard, please contact Standards Australia directly.

Standards revision protocols • Revision process – Australian standards • Anyone can prepare and submit a proposal for a revision • Proposal should be clear and concise, and justify the changes required • A working draft submitted with the proposal is well received • Standards Australia do not have the resources to revise standards “in-committee” • Working drafts (and proposals) must have wide support • Evidence of consensus/consultation required

• Proposals reviewed by SDAC and accepted/rejected • Once accepted – • A Committee kickoff-meeting is held, and proponents have ~8 months to complete the draft • Draft goes to public comment (two months) • Comments (if any) must be resolved by the committee • Comments deemed “Out of the revision’s scope” are parked for consideration at next revision

• Modified draft goes to committee ballot (two weeks), or if technical changes made due to comments, goes to combined committee ballot & public comment process (6 weeks).

Standards protocols • Inclusion policies • Generally follows ISO rules • Third parties can no longer be named within the Standard • Roles and responsibilities • Generally not permitted • Approval of the SDC required • Submission stating why it is essential is required

• Conformity assessment • Generally not permitted • Can be considered if clearly defined in project scope • Inclusion must be justified

• Only changes consistent with agreed project scope will be permitted

Standards protocols • ISO Standards • Direct text adoption strongly encouraged • Simplified project proposal required • Goes though similar project process as revision of Australian standard • Kick off meeting etc not required • Usually combined ballot/public comment process utilised

• If changes from original ISO text required, modified adoption can be considered

Standards protocols - ISO • Managed via ISO process (3 years max to publish) • Subcommittees report to a main ISO committee e.g. TC44 for welding • Standards development and amendments are managed by a subcommittee • Main committee and subcommittees are “mirrored” by an Australian Committee • WD-003 mirrors TC44, TC44/SC10, TC44/SC11 as participant, & observer on TC44/SC5 and TC44/SC7 • Revision can be done by the subcommittee or an approved working group.

• Australia nominates relevant experts to participate in these revisions and meetings • It is essential to attend the meeting in person if you have specific requirements • Travel subsidies usually available • Can now attend meetings via internet or phone (e.g. Zoom)

• Revisions are circulated to national mirror committees for comment and ballot • Ballot options include: • Positive ballot, with or without comment • Abstain if not relevant or technical experts not available • Negative ballot, with comment

• 75% positive ballot required from participating countries to pass to next stage

Aged standards • Aged standards are those aged 10 years or more.

• Many aged standards being withdrawn, especially if drafting committee inactive.

• Some work transferred to active committees e.g. WD-003 considering some WD-001, WD-004 and WD-006 standards.

• Examples include AS 2205 testing series, as relevant.

• AS/NZS 2205.4.1 (ISO 9017) • AS/NZS 2205.5.1 (ISO 17639)

• ASNZS 3545 (ISO 6947 adopted)

• As resources to revise aged standards are minimal – • ISO adoptions are under serious consideration when relevant; or, • Aged standard reconfirmed.

• Some aged standards have fallen through the cracks when committees are inactive: • e.g. Hoses for welding gases (AS 1335) withdrawn, ISO 3821 adopted as AS/NZS 1335 via ME-002.

ISO update • ISO 14731 underwent a major revision – published in February 2019.

Adopted in Australia as AS/NZS ISO 14731 (May 2020).

• ISO 3834 • Parts 5 (revised in 2015) and 6 adopted in Australia • All 6 parts being revised by ISO due to changes in ISO 9001 and ISO 14731

• ISO 9606 • Adopted in Australia as AS/NZS ISO 9606-1 in 2017 • Revision has commenced to revise and combine all 5 parts. Australia is active in the revision.

Summary • Standards are evolving • ISO is here to stay • Australia must be active at ISO to ensure its voice is heard • Need to ensure ISO standards are relevant and meets the needs of our industry

• Standards Australia’s resources including active committees are limited • >250 welding and related standards need to be maintained!

• Aged standards are being withdrawn, reconfirmed, or replaced by ISO standards

• Opportunities to join a committee arise from time to time • Opportunity to participate via public comment is free and open to all • Tools are available to quickly identify relevant AS, AS/NZS and ISO standards
