years plus involvement with API 6A.. Member of AWHEMS.
Alfred Kruijer. Shell Global Solutions standardisation department. Co-ordinates editorial support for
this revision of ISO 10423.
Tom Golden. Halliburton. Surface Products. Fifteen years plus involvement with API 6A. Member of
AWHEMS.
Hugh Parker. Shell (SIEP). Took over from Scott Higgins. Previously with Cameron, Vetco, Norsk

Overall project introduction, scope of work
Presentation by Ries Langereis:

API 6A start 1947,now 19th version

ISO start 1994,now 3rd version-why ISO

Realise action activity USA,100 plus participants

Legal and competitive forces in API

ISO TC 67/SC4/WG3 secretariat is in Washington

API is the only institute that audits manufacturing plants after licensing

ISO 10423 main body serves as the backbone of both documents

ISO positioned in Geneva

Based on member countries

No commercial background

Supported by local standards organisations like BS,NEN,API,DIN

Anew version of a standard needs to be balloted/voted and needs a clear majority to pass

China and Russia coming on board ISO
Plan of action 2006/2007
Eric Wehner, in his capacity of AWHEMS member, wants to be in a position to present a draft
revision of ISO 10423 to the API/SC 6 meeting in June 2007.

Current situation USA, AWHEMS
Eric Wehner on behalf of Jerry Longmire.
AWHEMS took the lead in developing the 19th edition of API 6A. Between 4-8 experts have been
involved. Main reason to work through AWHEMS was that they meet on a quarterly basis, whereas
API/TC 6 only meets annually. After successful API ballot and subsequent publication, the work group
kept finding errors. Also, there are some 5 or 6 unresolved technical comments and in addition,
suggestions for a future revision have been made to API for review during their SC6 meeting in June
2007. The same list is offered to the ISO 10423 work group. The AWHEMS work group is as yet
undecided whether to continue or to disband. Jerry Longmire and Eric Wehmer will co-ordinate the
AWHEMS input.
Handout and discussion of first standards up-date
Some changes to ISO 10423 based on API 6A 19th edition and AWHEMS suggestions have been
implemented in draft. Maarten Kuipers, Eric Wehmer and Scott Higgins will review the changes.
Explanation of work process
Alfred Kruijer proposed the following ground rules to ensure timely, accurate and complete revisions
are made to the document:
Backdrop

Large document – large file

Range of experts involved

Many changes expected

Several topics worked in parallel

Ping-pong foreseen in accepting/rejecting changes

Peak periods when approaching milestones

Expensive and valuable experts involved

2-year project
Needs

Workable document size

Distribution lists for drafts

Structured input

One working file

Change tracking

Version control and trail

Secure filing on backed-up server

Continuity during editing phase
Solution


Document split in two: text/tables and figures

Project Manager custodian of team & document

Comment Form not dissimilar to ballot form

Editors only work on instruction from Project Leader

One working file on secure backed-up server

“Track Changes” to Base Document only

Automatic and unique identification in page footer

Quarterly archiving of current drafts & pdf sent

One lead editor, plus one back-up for the duration
The work group indicated that size limitations on e-mail attachments may hamper proper receipt of the
quarterly updates. The request was made to investigate e.g. Livelink space and access for the workgroup
through ISO or Shell.
New NACE implementation
The work group decided to have an independent look at how API 6A 19th edition implemented the
new ISO 15156. Hangers and stems are indicated to be the main issue.
Thierry Cassagne (lead), Sam McFarland and Maarten Kuipers volunteer to take the subject on. A
liaison will be established with the ISO 15156 Maintenance panel. Eric Wehner will participate to
provide background to all API discussions from the past.
Suggested approach is to review remaining issues from the API 6A implementation, to seek comments
and problems from the manufacturers regarding practical application of the new ISO 15156, and to
present a position paper in the next work group meeting in December.
Forgings vs. Castings
ISO 10423 requires forgings for PSL 3 and PSL 4, whereas API 6A allows castings for all PSLs. Some
manufacturers have commented that prohibiting castings was restraint of trade, because some
customers call for API 6D products manufactured to API 6A PSL requirements. The protest is related
to products outside the scope of ISO 10423 or API 6A. No technical or safety justification for the ISO
10423 restriction was available for API staff to use in response.
API indicated they can consider adopting the ISO 10423 requirements if persuasive technical and/or
safety justification is presented. Justification does not necessarily have to show forgings as clearly
superior to or safer than castings. It can be sufficient to show that there are sufficient technical
differences that the two are not interchangeable in all applications, and that forgings are preferred.
Justification must be presented to API by equipment users or other independent parties; API cannot
accept arguments from competing manufacturers to resolve a question of restraint of trade.
Alfred Kruijer (lead) and nominations from Hydro, Total BP and Shell will investigate the issue and
write a position paper. Maarten Kuipers will try to mobilise Statoil as well. The study will include a
discussion on so-called HIPping of castings and a review of the definition of “wrought products”.
Suggested approach is to finalise the nominations by mid October, to involve the academia in mapping
out the differences with respect to e.g. microstructure, metallic phases, nature and extent of inherent

flaws, mechanical properties and resistance to degradation mechanisms. This should be done for all
material classes from table 3. Quality control aspects like NDT detection thresholds, detection hit rates
should be mapped against acceptance criteria. A position paper should be presented in the December
meeting.
Repair and re-manufacture
US practice is not to exclusively utilise OEMs for repair or re-manufacture. To avoid protests of
restraint to trade, API omitted Annex J from the API adopt-back of ISO 10423.
Eric Wehner mentioned that API 6DR now includes a text on repair and re-manufacture that is legally
acceptable in the US (Jonathan Jordan from API staff). He will review this text. Shell indicated a wish
to maintain the current Annex J.
Ries Langereis will liaise with API on the subject and write an A4 position paper by Christmas.
Any other business
None.
Next meeting
Next meeting will held on the 6th of December and will be hosted by Mokveld in Gouda.
